Comments

Natalia Dec 15 2023 11:26 am This movie is a great

Chizzy Nov 22 2023 12:07 pm I was hesitant to watch this film and it took me 1 month before starting this. Also I dont know i was a bit looking for rom com with english dubbed in a while.I have overcome also watching kdramas of lee jong suk since a lot of young actors are moving on the spotlight. Then i gave this i try. And then wow i can say that this is absolutely something a whole lot different and it doesn’t bore me watching even if it is not a rom com. The acting skills of lee jong suk waa on a different level. Most of his dramas are like the type of guy whom you will dream of because of determination and charisma. But in this drama, he was able to portray well his role a well rounded actor. Also with Yoona i am not usually a fan of her but she showed an exceptional level. I recommend this movie im sure you will love this.

neyo Nov 16 2023 10:10 am this drama is incredible. 10/10, that's all

haerin18 Aug 02 2023 1:16 pm This one is good I've already see some of the actors who play big roles on other dramas so I thought they will be the big mouse but it's not and I tried to predict the scenes but mostly I'm wrong haha. The title is so unique that in hangul both mouse and mouth used the same letters so the title can be both Big Mouth and Big Mouse if you are a Korean. Before the final scenes I thought there will be season 2 coz antagonist still not in prison and it so satisfying that he suffers what he deserve on the ending haha

Shairli Jun 29 2023 2:50 am Skeptical about the drama. Binge-watched for 3 days & it was good except Big Mouse character. Quite disapppointed but once taken over by Chang-ho, it meets the expectation.

Radhika Jun 22 2023 12:21 am Honestly I really really tried to like the drama and watch this drama. But I couldn't even finish ep 2. From the start, the storyline is extremely predictable and cliche. Everything about the dramas seems tiring, boring and just putting me to sleep. Disappointed with JongSuk I expected so much more !

Haisehn Jun 10 2023 9:06 am !!!SPOILER!!!

I'm watching this when it's still ongoing, I remember watching this at school because we already had classes that time, and because of having a little bit busy schedule I decided to stop watching it for awhile and watch it when it's already done, but I'm still stuck at episode 12, because one of my friend spoil me about the ending that Miho died because of cancer (can't remember the exact details but as far as I can remember it was incurable). Now I got really curious and I want to finish the drama.

If your into this kind of drama or if you don't get attached easily with the characters and everything this is one of the best drama, but if your a person like me, This is a warning. Yes this is a very nice drama (though I didn't finished it yet but it was a very nice drama) (+plus I'm a fan of Lee Jong Suk and those other actors that we're included in the drama).

Still, still get sad about Miho's death makes me more sad, they should've give Kang Ho and Miho a good ending they really deserve.

Kate May 14 2023 7:41 pm SPOILERS! I finally watched this after hearing all the hype about it but without reading anything about the plot. It’s been a while since I finished a whole drama in like 2 days so that says how much I got sucked into it, still have mixed feelings about it tho. The first few episodes were awesome, the whole plot was interesting even though it did have a few predictable things. Where things started going down for me… 1)Big Mouse being No Park. Saw it coming, didn’t like it. After painting him as this criminal mastermind of a huge crime ring he gets killed 3 seconds after being released. 2)I knew his best friend was in on it but him being the 2nd in command?!? Like are you freaking kidding me?! And Warden Park being the 3rd one?! Like how the hell did that very unlikely trio even end up being the Big three?? 3)For a “secret crime organization” literally EVERYONE was a freaking member!! And like Changho said the symbol was literally displayed in the restaurant entrance and NO ONE pieced it together. 4)But probably my least favorite thing, the rushed ending… just like 99% of all kdramas. They write a solid first few episodes and then they just give up and write the messiest ending possible and try to “fix it” in the last 15 mins. Although this is one set a new record, they literally “solved” everything in the last 5 mins!! I seriously thought they would make a 2nd season, that’s how bad it was. I did like how he killed Doha, kinda genius but also again very rushed. The subplot of the psycho serial killer son, like why even mention it if it didn’t even played out in the end?!? Hyejin never really got justice. No one did… Killing Miho, damn it that broke my heart had me sobbing, completely unnecessary. I really wished they could have kept the hype throughout the end, it could’ve been truly an awesome kdrama.

Skipper Mar 27 2023 2:48 am Ten movie is great but some events and scenes ain't all that thrilling.

Sweetapem3 Mar 21 2023 11:20 pm Good movie but then feels rushed in the ending. They giving off a good start and intense tension. But then they giving it more problem for rush ending like that. Slow pace in the first half episode

Koreanloverrr Mar 07 2023 1:28 pm This movie wasn’t it for me. The ML brought his problem himself. From the first episode, who takes a recording to the suspect and threaten them without any backing. How can you dabble into the world of the corrupt without fear and being naive, gullible and greedy. I don’t blame the other party for setting him up. He caused it himself. I don’t like frustrating dramas. He just acts without thinking about the repercussion which is just stupid.

Ajanigo Feb 17 2023 9:17 am SPOILER ALERT Didn't like the sad ending

Well the cast and acting were amazing Loved them all They deserved the award they got

Celine Feb 03 2023 8:31 am I'm I the only one here? But I think the character of Miho is a bit off, like why does she have to act that way? She definitely is revealing to everyone that she investigates and looking for answers. Can't she do it in a safer way? Like the scene on episode 6 where she went to the director and inspect her necklace, like wtf? She could have observed a liitle bit more and do the right move. She really throws herself in danger

Ant Jan 30 2023 3:39 am Woah I love this drama so much!!! When I first started watching it I didn't expect it to turn out to be hugeeee!! I mean from the Big Mouse vibe and the whole prison thing that was amazing I have to say the secret about Big Mouse was kept well and the rat references were just good I mean Jerry ( the little mouse in Tom and Jerry). I didn't expect Choi Doha to turn out to be a big creep towards the end but that was good he needed a taste of his own medicine. I also love the ending so much because if it was another movie industry (Nollywood) they would have found a way to save the wife from cancer which doesn't make sense but the writer wrote it well and I love it so much. I have to say this is by far one of the best dramas of 2022!!!!! Hands down!

Mercy Jan 22 2023 6:50 pm I've been wanting to see lsj after romance is a bonus I fell in love with him! I really love his acting the actress did great too first time seeing her acting. The ending isn't that okay the movie just start getting interesting towards d end so I'm like 2 or 3 episodes should be added to finish it all the same it's ok but I hope for a season 2. The drama is super hot. The couple chemistry was great too they really deserve the couple award

junejia Jan 02 2023 6:41 pm I finished watching big mouth today and they said the ending was not good as the drama it started but I opposed with it. The ending for me was quite satisfying.

It's a personal rating not just because I'm a fan of yoona and LJS but because the drama was so good and interesting plot. I love this drama I want season 2 with different heroine.

Yasmin Dec 31 2022 9:13 am I knew it❤️. Congratulations to Lee Jung suk and Yoona. They really deserve the awards. I usually don't watch action series, but i loved this so much. Hope that he will act in a family drama next time. Keep it up? fighting ❤️❤️

KST Dec 24 2022 12:05 pm I just finished watching this series. Actually this story was really amazing but the ending was not satisfying. Anyhow this drama is a good crime drama represetation. I really love its style.Finding the big mouse was really impatient thing.Lee jong suk and Yoona had a great chemistry. The acting was really superb. All most all the actors act well. Really recommend this drama to all who like to watch thriller drama series with crime and mystery.

Ciepao Dec 24 2022 5:27 am This drama had a good start and flow, but awful ending.

I was so excited to watch this drama when it aired. I saw a lot of people talking about Big Mouth on every social media platform that I have. And when I finally had a time to watch this series, I understand the hype. From the story, all of the characters, the problems that the main characters are facing, to the gangs, and the curiosity to find out who was big mouse will really make you hooked on this drama. But as the drama near to its ending, I was so disappointed. They introduce more problems just for them to rush it in the finale. The story went to the top and straight falls down. It was so dismaying. Unless they will make a second season, the ending won't get the satisfaction it deserve. I also guess this is the reason why I only saw the hype until episode 10 when it was airing. I never saw people hyping it up when the drama end. They waste a good drama, actors and actresses just for a rush ending.

I'll give it an 8/10. Other than the awful finale the drama was good.

Kfan Dec 14 2022 8:22 pm SPOILER ALERT

I do not feel bad for MiHo. She brought it on herself and honestly if this was real life the “higher ups” would’ve been killed her and ChanHo.

Dreams_Come_True_Juseyoooo Dec 04 2022 11:02 pm Omg i can't wait MBC Drama Awards December 30 ... Cuz this drama ... Wish this drama can get many award !!!

Big Mouth the only rating kdrama in MBC get 13% rating ... Only this drama ...

Kaeselionvidoti Nov 20 2022 11:49 pm Lee Jong-Suk is my favourite of all the time..., i wish Lim Yoon-A couldnt die... best series 2022 great supporting actors best story line

Mr critic Nov 18 2022 8:44 am The storyline is very good, I could guarantee that it is a very interesting story. Storywise and acting-wise will be excellent. The main problem people are angry that they wrap the storyline in 5 min. If asking, should I watch or not? You can watch it but remember every storyline will end episode 16 in 5 min making you feel unhappy and horrible. I wish they can extend just 1 more episode instead of wrapping it in 5 mins. I sense the writer forgot there is finale and decided to end the show it in 5 mins.

Overall story wise :8.5/10 Acting: 10/10 Ending: 2/10 by Mr critic

Mean Oct 18 2022 7:24 am The ending was not bad but how the ending wrapped up took 5 mins of the whole 16 episodes. Gosh. The ending really killed my satisfaction of watching this series.

kdrama lover Oct 13 2022 8:17 am definitely not 10/10. Maybe 8/10? I love every episodes until i watched the last episode, it was a bit disappointing... The ending was very rushed, we cannot enjoy how the baddas got punished. A lot of plot holes. Still have a lot of mysteries unsolved. [SPOILER] Like what the basement lab looks like? What did they do in there? How did Choi Do Ha take all the golds and where did he move them to? How about the Chairman Kang's autopsy result? What about Chairman Kang's will at the end? Also i feel like Hyejin's death and Chairman Kang's son things are pointless. Dr Han killed Hyejin but never got exposed. The death of Choi Do Ha also not satisfying, can just kill him from the start why need to go through all the major election and the trial? sigh

Shula meidav Oct 06 2022 11:58 am A very good serie.wonderful acters.well done.

Michelle Sep 30 2022 11:18 pm [Warning, spoilers ahead] Absolutely amazing drama until the last 30 minutes. It felt like the writers forgot that this was the finale and suddenly has to tie up a lot of loose ends but just didn't have the time to do it properly. Yoona dying felt a bit quick, but I'm not upset with her dying overall, it's more how they rushed it all. They essentially did a montage to try to show how the good guy "comes out on top" at the end and the bad guy gets what is due but it's not quite as satisfying with how they did it. The chairman's son was never brought up or mentioned again, it seemed pointless to say they were trying to find him if nothing was ever concluded from that.

I'd still recommend this drama but would warn them about the ending.

Candela Sep 29 2022 6:42 pm I wish I could erase it from my memory, so that I could rewatch it again, Jong Suk❤️❤️❤️

Lorf asiled Sep 27 2022 10:28 pm Everytime Lee jong suk lead the role always got me excited , he never failed my expectations in portraying his role, always the best Lee Jong Suk

Tee Sep 24 2022 2:31 am There is one particular mystery I failed to understand. We all know that pch is an orphan, the question remains "what happened to his parents, how did they die?" There must be a link to this explaining who pch is or was in my own opinion

Tolulope Sep 23 2022 3:13 am Season 2! Season 2! Season 2! I want season 2...To be honest, I enjoyed every episodes...the anticipation, the suspense, the acting and casts... awesome. Rocking Big Mouth Rap song JustThis Brand New.

Tolulope Sep 22 2022 9:55 am Season 2! Season 2! Season 2! I want season 2...To be honest, I enjoyed every episodes...the anticipation, the suspense, the acting and casts... awesome. Rocking Big Mouth Rap song JustThis Brand New.

Liza Sep 22 2022 6:14 am I want season 2. I wanna see who is the real son of the late chairman.

Morchy Sep 21 2022 10:05 pm The drama was so good and enjoyable but what the heck is the end?!!

Lleesaa Sep 21 2022 9:02 pm Sometimes it is funny but also quite dark. Everyone has good acting. Gong Ji Hoon is so pitiful haha! Mayor sooo creepy at the end I want to box him! I want 2nd season! Highly recommended!

Arwi Art Sep 21 2022 10:22 am it is good for the first episode to the middle, but not good after that to the end

Pukinaaa Sep 21 2022 4:47 am The unsolved cases or unanswered question in big mouth really fits the reality we have in our world, many dead bodies still missing, many innocent people being use by powerful person/people, the people who have money have Justice. Thats why i love the ending of big Mouth, the ending is a bit rushed but overall its good and one of the best dramas in 2022.

Star Sep 21 2022 3:55 am This was wonderful. A brilliant piece. The storyline, actors/actresses, production and all is a hundred percent plus. It's very much recommendable.❤

Miho Sep 21 2022 2:13 am This drama is still a masterpiece even with rushed ending, i suggest u to try and watch, And all of the actor nailed theyr character and the directing is so good.

1989 Sep 20 2022 7:47 pm Even they don't have a lot of promotions in this drama they still managed to have High ratings, well its not surprising because the cast are so amazing i rate it perfect ⭐⭐⭐⭐⭐ and the ending is a bit rushed and sad however i expect that to happen, plot and ending i rate it by⭐⭐⭐. Overlall this kdrama is one of the best dramas this 2022 i looked forward seeing the cast of big mouth in the awards night ♥️

Well Sep 20 2022 11:29 am All cast ⭐️⭐️⭐️⭐️ Story line ⭐️⭐️⭐️ For first episode - 4th episode I can guess everything ? I know what will happen on next scene. I can read every single scene. Watching this because LJS and IYA only. Story line not my type off drama. But I love scene when Miho noticed blood on her teeth and nose. It’s so sad. And from that scene it’s become more sad to watch it. I think it will be happy ending but it’s not ? well I think I can watch another drama from IYA in the future

Arigato Sep 20 2022 1:24 am For me its still good even though its a little bit rushed, there are alot of unanswered questions but its okay if they will have season 2, its okay to have a new season with a lot reason rather than having new season with no reasons to comeback.

Minnie04 Sep 19 2022 6:08 pm Serious , dark drama with few to no romance ( well they are husband and wife so the their love story line passed those dating period , ha) but for me it’s satisfying ending , just little bit rushed . The cast was outstanding everybody play their roles well. Anyways , who doesn’t love Le Jong Suk . —-Congrats for your awesome come back —-. Can’t wait for his next project. Genre like this will suit the best for him.

rushed ending. huhu Sep 19 2022 10:52 am SPOILER! SPOILER! why was the ending sooooo rushed!!!!!!!!! at the end he still punished the badguy that way, what PCH said to warden when he was convincing him was BS. with that ending, you can just kill those badguys from the start. hahahaha and what do you guys mean by hyejin death was a mystery? she was killed and cremated silently. who can identify her ashes? you better watch it again and stop skipping too much scene. and about mr kang son, he cannot do much even if he was found coz in the first place he's a "psychopath", it was confirmed in tak kwangyon case.

Roxie Sep 19 2022 6:31 am This movie really driving me crazy. I can't stop watching and thinking it all this time since I'm done watching this episode. They really all deserved a standing ovation ?❤❤

Kdr Sep 19 2022 4:05 am It was a bad drama, a waste of time and I don't care how much you are a fan of the actors and actress. If this was an American drama it will get 5% on rotten tomatoes.

FullL or plot holes and an anti climatic ending.

There are soooo much other better dramas and this is not one of them. 3/10

Don't recommend watching unless you want to watch to pass the time. Please don't do season 2.

Carol1646 Sep 19 2022 1:56 am I love this drama and wondering if there'll be a season 2 to answer all the holes? --SPOILER-- . . . . What about P. Kang real son? They don't really mention it but it is obvious that TKY are taking the blame for P.Kang's son, right? And Jang Hye Jin's death is still not yet revealed til the end... Did Park Chang Ho succeeded become the next major?

And I might've missed it, but I did not understand the point of the labs, what are they researching in there? I thought they were testing on people (like lab rats) but there's no explanation about it either.

Do they deliberately give radiation to the inmates? So many questions, but overall , its a good drama. Lee Jong Suk is so so so so so so so handsome in here. I didn't expect his baby face to fit such a badass role. Hehe.

"Korean dramas' ending is awful!"

well.. This has a point in writer's side. As we know korea has produce one of the best series in crime, thriller, action even in historical category but we felt like they don't give a proper ending exactly because the plot is a Daebak! We are unable to accept the lone reality.Same happend here regarding the plot. But! The ending was too rushed. The villain who was a jerk enough to kill even ML's wife only got the 10-15 seconds pain.

And another point when in 16 epi miho said "we still have time" I was kinda relief and thought like " ofc they might not show her die! They could have shown her rest on his shoulders in beach or somewhere. Wow that's great. " ;-( but then at the ending i was like... ?.

I think they just dragged the big mouse reveal part bit more than necessary. If they managed to get to that point at least in epi 10 it would have been manageable. It doesn't matter all the things are not reveal in the end.. But.. Ugh.. Idk. Anyway......

Thank you for bringing a kind of unique and exiting drama despite those things. Yoona unnie!!! You did well. ❤️ (Congratulations on 15 anniversary! GG?)

P.S. This is my first time watching a drama at the same time it's airing I guess. ?? I could last because the plot was so active until the end!

Keynjosep Sep 18 2022 9:42 am First of all, SPOILER alert. I'll be writing this review while mentioning most of the storyline.

It's been a great 8 weeks. No, actually just 7. This Noir, Action Korean Drama is definitely good. But it misses the very last spot which is the ending. I am absolutely dissatisfied with that last 20 minutes in episode 16. A 15-minute slow paced scene about a dying character the a 5-minute montage of MC's badass revenge? Like why? how? just like that? It is so rushed and many subplots are left hanging. I'll mention the 2 most obvious left out subplots. First, "Hyejin's murder mystery". Hyejin was murdered but her body was never found. Ko Miho is supposed to be investigating that, but they dropped it. Second is Chairman Kang's serial killer son. He is clearly the one who killed Big Mouse's daughter the brief flashback in episode 14 shows that but then didn't explore it further. That same serial killer is also the one reason the accused serial killer in Gucheon Prison is apprehended.

K-dramas has always been notorious for awful endings. It seems like the writers and directors don't know how to proper a story. I am hoping they announce a 2nd season to actually finish the story.

Song Sep 18 2022 8:01 am Is it going season 2?

papabomb Sep 17 2022 11:23 pm Okay...... so no one will ever know what's happening to Hyejin.. and also the part where Chairman Kang is being killed.. and his son? what is his purpose though in this drama hahah.

fidadudu Sep 17 2022 9:47 pm I really don’t like the ending.

Karti8 Sep 17 2022 7:26 pm I hope the next season will comingsoon

Ang_Gale Sep 17 2022 4:09 pm Simply epic! keeps you attached to the end! absolutely recommended! It is a raw and sometimes violent and very sweet drama at the same time... Love it!

Mimo Sep 17 2022 3:10 pm Very disappointing ending, it was super fast, and what happened to the serial killer son? It felt like the writer and producer didn't agree on the number of episodes until recently that it was a very hectic ending with a poor plot. Of course, the drama is epic but the last episode ruin the quality of the full drama.

Hawraashi Sep 17 2022 2:41 pm What the hell was the ending!!!!!!

Giftwilly Sep 17 2022 1:58 pm I hope

One day we get season 2

torres Sep 17 2022 12:49 pm i liked the entire drama but the end was short like all that happened but the end and revenge was just a small part i mean it still good but it would've been much better with Bigger Revenge

Yoona Sep 17 2022 12:33 pm satisfying drama ending, at least the ending doesn't hang for the main character, good job to everyone involved in making the drama ??

Nekochan Sep 17 2022 12:16 pm What the hell was the ending ??!! So many mysteries unsolved !! Why so rushed ?. Its like the story deviated from the original story , would bring new story on top of another with no proper closure. For instance the chairman’s son , he was brought up so many times making us think he will have some role but no it was just waste of time , too many dragged on parts which couldve been used for stories that needed more screen time, the paper which started all these shouldve been discussed more but all we got was 3-2 secs in the last episode

Yol A Sep 17 2022 11:50 am Soooo many questions without answer... The drama is great from beginning until last 2 or 3 Eps... Disappointing.. I would rate 7/10 They should've done this until 18 eps

bby Sep 17 2022 11:42 am why there is so many plot holes in this drama? why adding another plot twist and problem when there is previous problem need to be solved? why kdrama recently so obsessed with sad ending? wanna be different huh?

Yol A Sep 17 2022 11:03 am That's it ??? What about the son in Texas ?? ( Kang Sanggeun )

Molly Sep 17 2022 11:02 am Ending was such a disappointment. They focused way too much on finding who big mouth was and rushed the ending. I’d rate this 7/10.

Yeay Sep 17 2022 10:53 am Soooo satisfying! For ko miho, its ok for lil emotional scene in this drama but so far this drama is very ???

Congrats all picture and name above❤️

Ayesha Sep 17 2022 10:51 am The victory is too rush, taking away the excitement while screen time were mostly spent for some dragged parts. Some things remain unrevealed, it needs several more episodes

Name Sep 17 2022 10:06 am Bravo!!!! The best drama in the year.. no need season 2 or whatever part 2 or whatever ridiculous open ending sad ending!!!! Im very sure this drama will satisfy all the viewer, not play with ridiculous drama like others so manyyy right now...

Congrats all the cast!! From main to allll you dooo a veryyy good jobb! Salute!

Thanks for a wonderful show Sep 17 2022 2:45 am Im impressed about the wifes of changho, kong ji hoon, choi do ha because they are the example of women in different situations and i believe they will do right thing in the end especially the wife of choi do ha. #womenempowerment

Catherine Sep 17 2022 2:19 am Love the show! I gave only one question: why are so many close ups of the face, ears? Is there any particular reason?

Giftwilly Sep 16 2022 9:52 pm I would love it so much if there was season 2. Loved it.

sHh Sep 16 2022 4:36 pm Wonder if some people commenting are really watching the drama. At this point of commenting ep 16 is not even released yet - that is unless one can leap through time and go forward 15hrs, so how can one predict that ep 16 is boring?

I believe most stuff had an answer already - either go back and watch in detail or if they are questions yet to be answered than the last episode is always there (uhm, no, once again, it's not broadcast yet).

One thing though, there were rumors since early days of the drama that there will be season 2. I've not seen any believable signs to that yet but yes, I think there could be but even if there isn't, the loose ends can be tied up today. Of course it is obvious that they can easily weave the story into the next season without being awkward.

Sue Sep 16 2022 12:20 pm Kind of annoying how they are adding more plot and twist while we only have 1 episode left. There are still so many things unresolved. Ep 16 was one of the most boring episode.

Meerah Sep 16 2022 8:59 am Kudos to all casts, they nailed their roles very well except Ash Kim and Ko miho's dad... Very proud of them all, Saranghae!!

Meerah Sep 16 2022 8:52 am For me ko miho's father and ji hoon's wife are both useless in this series. Can't Ash Kim see how Junhee and Dr Kim's wife are supporting their husbands? Same goes to miho's dad,he didn't even come visit Chang ho for once...So bad

Emar Sep 16 2022 6:47 am It's all kind of cheesy, but it takes itself seriously enough to be pretty entertaining. However, if there is one reason I would recommend this, it's to experience the absolutely amazing performance by Yang Kyung-won, who plays as Gong Ji-hoon. I can't praise it enough, it's brilliant, makes you laugh everytime, from his slow break-it-down-for-dummy syllables to the eccentric movements to describe his mood, it's outstanding.

Oh Puh Liz Sep 15 2022 4:12 pm Of course they should end the drama the way you envisioned it. That's the Best and Most logical and Exciting. Oh they should have hired you to be the writer! If they did everyone wouldn't have to make themselves be bored to death every episode until the current ep 14, including thyself, and still feel compelled to watch it every week. If they hired you to write the story then Miho would have become the one with the most scenes instead of the miserable few! Please apply to the producers to write season 2. You can do it!

MihoIsBigMouth Sep 13 2022 12:18 pm I hope the plot twist is Miho being the Big Mouse, otherwise the ending would be boring without any plot twist.

BiggyMouse Sep 13 2022 9:53 am Spoiler:

Interesting...Now that Miho has been affected with the leukemia...makes Park Chang Ho even more perfect being the new Big Mouse. The grievance is now equal.

Pukiimone Sep 12 2022 7:04 pm Nxt ep will be the most interesting part its always the end in every drama, time to reveal the Truth to answer the questions, its either happy ending or bitter sweet ending no matter what is the ending guessing who's big mouse from the start until now makes this drama great.

RphHH Sep 12 2022 6:49 pm I don't know, but for me this drama quite boring, at first I feel it's interesting but after Ep. 10, I feel it's boring coz everything is so predicted, now I'm at ep. 14, unless there's a plot twist, then it is just an average k-drama for me.

dramawatcher Sep 11 2022 3:53 pm @Aigoo

It's in the early part about ep 2 or 3 but I think it's unwise to delve right into the scene without understanding the story first since that can easily give rise to deeper misunderstanding. So I suggest you start from the beginning.

Before you check it out though, let me offer an alternative perspective for a person whose culture is probably in between both Koreans and Thais, and also one who has seen the drama.

In the scene, the lead was trying to antagonize the serial murderer because he was trying to find a way to seek death. He boldly scolded the murderer and asked if the murderer's mother did not drink seaweed soup but instead had Tom Yam and another Korean soup while she had him. Now if you follow a little Korean culture, you'll know they drink seaweed soup in important occasions. It is a mild and nutritious soup. It's what a pregnant woman drinks as opposed to spicy soups which could agitate a weak stomach. The writer, I believe, chose the two soups because it's what's spicy first off in her mind. If she had meant to put down Thais she wouldn't have listed the other Korean soup too. It is just like in my culture, although we too have quite a few spicy soups, if you are going to ask me to list two spicy food I'm going to say Tom Yam would be one of them because I like it and it's one that comes immediately to mind; not because I'm looking down at it but because it's famous even if it's not from my own culture. We all have our mother's tale about what to eat and what not to eat during pregnancy and I think that's about all. It's unfortunate that another country's dish is used as one of the examples but I think there really is no malice in this case.

Aigoo Sep 11 2022 2:49 pm Help someone can't tell me which episode make Thailand People mad ??? I was shocked when my friend tell me this drama get criticized form some Thailand People !!!! Because Tom Yam right ??..!!!

Hhhhehheh Sep 11 2022 1:49 pm Even if this is bitter sweet ending or happy ending its okay because i see character developments especially for changho so no matter what happens in the end im grateful to this kdrama i learn something that i can use in life, thank you.

Nami Sep 11 2022 12:45 pm Aside from Miho and Changho, my top 5 characters are: 1. Doha (his role is make me itchy and want to punch him the more I watch this); 2. No Park (literally my favorite kind ahjussi, deep condolences for him); 3. Yang Chunshik (devil with an angel heart); 4. Park Youngab (my hands was also got itchy and want to slap him AT FIRST); 5. Kwangyeon / the "psychopath" (Big Mouth is incomplete without his role). Moreover, all the characters in this drama is amazing. This drama itself is amazing. Thank you to all the staffs production and all the actors/actresses. If the ending is satisfying, I would rate this drama 9.5/10. But as now per episode 14, I will rate this drama 8/10.

SooY. Sep 11 2022 2:03 am A bit spoiler*****

So in the end writer obviously conned us. Misleading us to find the big mouse! He gave us so many hints that "big mouse is helping pch so no need to find BM. Focus on the true villain here! If you can!" And here even a small character has a story. May be that's what make this drama quite unique other that the fact that conning us.

Mme emem Sep 10 2022 11:57 pm Im not worried about whos big mouse but im worried about miho and also the ending if this is bitter sweet ending.

oui Sep 10 2022 1:59 pm ohhhhh and my new guess is simple like this too if tky not the elder son may be he is a scapegoat....change his life...,he go to jail his mom will survive and may be the elder son is real psychopath and TKY is normal good guy who go to jail instead of the elder s son ?!! he did all for his mom may be for mom bone marrow transplant...

yes may be it like this if he not no.1 big mouse he will be only a poor scapegoat. and it will be happy ending i guess miho is ok and pch back to be normal and big mouse no more illegal look at the plot about food test scene everyone became good and respect new big mouth pch who became big mouse leader in a nice way ( in case if miho die so pch keep kis promise to be good leader)

Vince Sep 10 2022 12:03 pm Who is the big 3 mentioned by jerry? We already know that the warden and park changho's friend are in 3rd and 2nd spot but whos in the first spot?

arita Sep 10 2022 3:58 am The plot is ok, but I am more amazed by casts actor beautiful visuals haha, I see all people did their role very well, and suit their character perfectly!! Kudos and bravos to everyone!!! You are all did amazing good job!!

Youuuuuuuuu Sep 10 2022 1:03 am @jummybaby yeah he is, but im guessing that big Mouse is not what viewers thinking of since the start, if im not mistaken, the word Big Mouse is the clue to find the truth like the tittle of this drama Big Mouth, if my theory is Right this will be the ultimate plot twist of big mouth and maybe the best plot twist of kdramas because no one notice it, i hope im right haha

Rain Sep 08 2022 9:50 am Despite the motherhood daily journey, i was able to watch the first up to present episode in one day. I was hooked. I can't wait for the ep 13 to be released. Lee jungsuk never fail his fans. He really is an amazing actor. I really thought that lee jungsik is the real big mouse since he grew up in an orphanage and was really a psychopath. Lol pretending to be a nice person. Now that i just watched ep12 i think the real big mouse was jerry.

Moon ? Sep 07 2022 9:58 pm I think the real big mouse doesn't exist, maybe the big mouse is just a scenario made to cover up someone who stole the money.

StarAngel Sep 07 2022 5:45 pm @Female_Human From the start, Park Changho is a Smart lawyer. he said he excelled academically. Like his family jokes, He smart but poor and have no connection, that's why he always loses. Politic world is tough. And now He still smart but have Power. That's the difference. also the situation which make him pressed in prisoner surely force him to think creatively if he want stay alive. He also saw a lot of sly from those criminals, of course He also learned a lot how to be sly. That's how Park Changho became a mastermind now. I think all of this is make sense. When you're pressed, you are at your optimal strength.

Omoblaqee Sep 07 2022 3:52 am If big mouse is an organization then Soontae is in this with Jerry as well.

Tom Sep 07 2022 1:13 am Its really obvious!!! Its Jerry! We all knew Kwak Dong Yeon gains popularity already from a lot of series he was on. And it doesn't make sense if he doesn't have a special role isn't it? I remember him though being villain in strange hero...

Haha at ah Sep 06 2022 12:34 am Im more interested in the flashback of this drama for me thats the most exciting part of this drama.

Pearl Sep 05 2022 11:10 pm I think Chang-ho is big mouse and he has split personality ?

SmallMouse Sep 04 2022 6:33 pm My guess is Tak Kwang-yeon (aka Psychopath, Inmate 1503) is the Big Mouse. Looking for an answer, at the every beginning I excluded all of the people shown as authority/leader cause the would too easy (Room Leader, Warden Park, Chairman Kang, Mayor Choi or even the Miho's father). The key is to point at the most unexpected of the characters portrayed in the drama - so Psychopath. From the first episode shown as mentally weak, with no hope or tomorrow (being on the death row), easily manipulated, impulsive, highly unreasonable and probably addicted to some substances. That being said during the whole series we've been given some strange, till now not explained scenes including Psychopath: 1. He was one of the two people showing up when Park Chang-ho was looking for a support. There was the Room Leader, Big Mouse suspect from episode 12 - whose probably not the Big Mouse but clearly bonded with the Big Mouse and high enough in the hierarchy to stand up as Big Mouse himself. And then - without any particular reason - there was Psychopath with his story of hospitalized mother. 2. Although Psychopath took part in the attempt to kill Chang-ho and was then put in the solitary confinement, he was not murdered or forced to sucide by wardens. Rest of the prisoners lost their lives. Although people were saying he was saved because his on the death row and won't last anyway - I mean was he? Maybe there was another reason for Warden Park to keep him safe. 3. Ko Mi-ho got the job after rescuing Psychopath. The skills or the importance of the saved individual - what was actually the factor that influenced the decision? 4. The strange, unspoken relationship between Psychopath and Gan Soo-cheol. Two scenes showed us that they're for sure connected. First - guards trying to calm down and catch furious Psychopath with tasers and then Psychopath goes to Gan Soo-cheol looking straight in his eyes. And they are looking at each other for a little bit too long. Gan Soo-cheol looks almost frightened - is it because his boss is about to be killed or is he looking for a hint what action he should take? And the second scene in the episode 12 when Psychopath rescues Ko Mi-ho and Gan Soo-cheol comes into the room trying to shot Ko Mi-ho but Psychopath stands on his way. Again - strange facial expression from Gan Soo-cheol and his not shooting but instead punches Psychopath and pushes him aside. So, is Gan Soo-cheol one of Big Mouse's people? Does he recognize Tak Kwang-yeon as the real Big Mouse? 5. At the banquet people were talking about Chairman Kang (Elder)'s son who got disowned because of drug use.What if this son is in fact Tak Kwang-yeon who seems to have this kind of problem? And maybe his mother suffered because of Chariman. That would be a great reason to go against him as Big Mouse. 6. How could he be a model inmate with his past, sentence his serving and his fame of being crazy? There has to be another cause of his privileged position. 7. Psychopaths are kept in the mental institutions, not in the penitentiary. But it's easier to manipulate people and managed business from the prison thus he chose it himself. These are just some of the thoughts I had. The least suspected, the least suitable as a leader and the weakest yet still in the spotlight every time something crucial happens. Considering Big Mouse is the biggest scammer of all, what if he scammed us all hiding under this image? Dear Readers, thanks for your attention. I hope I didn't stir your guesses too much.

Gg Sep 04 2022 6:21 pm I believe its either changho,miho or miho father is big mouse, i dont believe it's jerry because he's so obvious, i only suspect Jerry as relative of changho.

oui Sep 04 2022 1:23 pm the Mayer wife,shes not blood related to the elder?! and the room leader daughter no detail how and when she died if she missing or die young then i guess after ep 12: since gong ji hoon's wife saying at art gallery that Hyunjoohee is not real niece of the elder something so i think about Mayer wife is room reader s missing daughter.and thing starts from long term plan to build all connection. like to catch the bad guys,you've got to think like a bad guy.That why big mouse organization connecting ppl from many careers, i believe it must be something effects from the past urban development project since Mayer s grandpa and the elder are friends and start the project together so because of the greedy project destroy many family in town including miho s family?!!. Her mom die cos?! her dad quit from police department cos he sick of corrupt system that never take the elder or spoon kid heir down with any charge! This city is full of dark side and its the elder empire from generation to generation.so i think big mouse is all the family member of the victim who once in hospital or being sick and became part of guinea pigs on treatment or tested new medicines and the last person who in charge in this project is Prf.soe jae yong. He may be want to do this work no more and try to reveal truth.so he try to quit or not be in silence then he disappears or even fake dying we will never know. Its turn table point! All we know is prisoners sent out to clean and sick and need blood sample on the time same as patient in secret floor from the beginning ep. even now at the lab not reveal the truth yet what behind the secret door. As you see the hint from room reader and Tak Kwangyeon only 2 person who went to the confess room ( early ep that pch said he will do the prisoner request) that only 2 this show up there and talk about family member one talk about lost daughter one talk about his mom at hospital this 2 give hint word to pch to check hospital. so for me this is the possible way that big mouse is the brain of big mouses organization ( that full of many small mouse but gathering to overthrow,seizure the elder family who control all the power. people who lost or lose their love one became one of prisoner you can see jerry and his sister ( he ask about his grand ma with his sis so may be his grandma be one of guinea pigs too) same as Tak KwangYeon mother i think tak kwang yeon mom is being part of the victim.even Pch we dont even know why he lived in orphanage house but i guess that all kids who lost family member from urban project is connecting to some case too i think big mouse is really big organize who connect with bad size like in Gotham city ( batman) so big mouse leader is hero who live in the dark shadow and fight for their love one.its all victimof the elder about urban development project.im quite sure about that. and for Mayer wife i think she will be the one of the turn table point not miho but her.The elder took her to his family and raised her well she became his favorite heir. She may be remember her past.i dont know its 4 ep to go but still many small detail puzzles that this series no telling yet Miho lost her mom her dad is ex police of course he must have all connection with head of prisoners,the gang and the warden. but me,i think Tak Kwangyeon from the beginning is big mouse leader,i think his mom is on new project if medicine test.and the more you see this series he shine up a bit more and more till became important from ep 12 you will see him more often i guess. Mihos dad in the bad case if the writer need more drama in this so he can be the brain of big mouse too he may be gathering all the family of the victim together he and room leader be the builder this org in concept to catch the bad guy you need to think the same way and miho dad is the one who know pch the best but still i think big mouse must be someone young and smart to do drugs business and do many dirty job or bad thing and can be Tak Kwangyeon the writer not reveal the background about him yet so all we know is he is psychopath but no more detail ( in beyond evil he good at acting with eyes) so last i think one of all this can be brain of big mouse org. its all about defraud ppl and i think its not miho cos way too be Anti hero if miho is big mouse cos she must be drug leader and order ppl to the bad job and build up connection nahh not her in my opinion. jerry is too obvious character,the writer and director always point at him tooooo obvious but korean serie always plot twist and twist (look at the when the camellia bloom) you will never know who the killer till the end and you guess every ep who is the killer and when reveal the truth we always say "omg its him?!!" so i think the same thing... Kong JiHoon,Seo JaeYong,Hyun joo hee this 3 is involved big mouse org for sure but in which way i dont know yet but for now i will give Tak Kwangyeon is big mouse in my mind miho dad is the elder of bm org room leader is not dead yet.cos he need to come back the reveal the truth about his family his daughter how she die or missing and pch lawyer must be BM lawyer to clean all the dirty job as i mention before ( he quite upset in 1 scenes that he know pch go to investigate without him the last doha he want to be leader instead of the elder.He is the elder junior style.He think about revenge but go too far too dark side.He cant be big mouse for my opinion cos big mouse must be kind and do some good thing like gangster personality like the godfather style,many ppl loves and adore big mouse and not fear to work with big mouse cos they are in the same goal that why its became big secret org so for this i think Tak Kwangyeon still have this style of leader.still jerry is big mouth cos he start all the fake news to pch big mouse is someone else if jerry is big mouse its too easy guess cos camera loves him and hint and point him all the time when something happened its mot kdrama style they need to draggggg and let us guess and guess more and moree so see it in 4 ep and i think the real big mouse who create the plan will show up in 15-16 must be twist and twist hahaha

NoPark Sep 04 2022 12:15 pm I can't believe it... Wasn't it obvious to us since PCH got to the prison that it could be the room Leader, then why drag therevelation like it's so special?

TD Sep 04 2022 11:42 am I know some people would still not understand this movie no matter how much they watch it. How can some people still think that Choi Do Ha is Big Mouse. They are clearly two different people wanting different things.

BiggyMouse Sep 04 2022 11:39 am @Mermaid...lol, to be honest at this point of the episodes we've gotten to in this movie... I do not know the Writer's plan nor the Director's deal...turns out it is just movie...all the drama and anticipation is too much that they've overdone it, lol....I hope this movie do not fail in the end, we are left with just 4 episodes, wondering how they would contain all the clues and anticipation they've build...To me the best plot twist is Park Chang Ho's lawyer (Soontae) being Big Mouse. Nevertheless, let's see what writer Ha Ram has for us.

Scarlett Sep 04 2022 10:49 am It is not sure! What if Choi Doha only stole the money and gold but everyone thought Big Mouse stoled it? For a reason.. Even if Choi Doha wants to take revenge on the old chairman, he is a criminal too and hurt Changho. Btw I think they messed up the story a bit...I wouldn't want Choi Doha to become such a monster who would get Changho and Miho killed. Pity...

Mermaid Sep 04 2022 9:20 am Guys what drama you all watch? Choi Doha is Big Mouse, in a previous episode it was revealed, they showed him as he visited the stolen gold and money. I think it was obvious... Although yeah, who knows how the idiot script writer and director finished this drama...

sierrabluee Sep 04 2022 7:20 am im watching ep12, changho is asking nopark is he bigmouse? ?

Tansythistle Sep 04 2022 6:22 am Will see it through....too many theories, too many confusion. But I think Miho can be a big mouse or her father. 2 weeks more for the revelation.

Chen Sep 04 2022 5:29 am Don’t you guys wondering who called Jung Chaebong after they killed Seo Jaeyong? It’s Doha! He seems not really clean and good person. I believe he hide something bigger

Ezme Sep 04 2022 5:15 am I believe we will get legit hints nxt eps and for me big mouse is miho, shes the only character that got overshadow by other characters for me that's suspicious.

Spirit?✨? Sep 04 2022 3:28 am After episode 12 Now what's important is who killed room leader??who was the one tried to save park changho?is it jerry? Truth about seo's paper? Intentions of mayor doha? There's still too much to cover??‍♀️

Arif Se. Sep 03 2022 11:39 pm I feel suspicious with Kim Soon tae.. look at his face before the building exploded. Seems like he already knows that the building will explode and No Park will die. Ooh poor him.. finally he will meet his daughter in other world.

Cj Sep 03 2022 8:17 pm @Big tounge, did you really watched the 1st episode? Park Changho's nickname is Big Mouth and that's why everyone's searching for Big Mouse because he is the mysterious one.

Big tounge Sep 03 2022 8:06 pm Bro all of the viewers only focus in big mouse but they are not wondering who is big mouth since ep 1 what a master directing/scriptwriting hahaha. This drama desserves a lot of fans and awards! My tip to you guys, dont just find big mouse you need to find also the big mouth.

Mama alzam Sep 03 2022 6:36 pm I think noh park is a father of park chango (because same familys name is "Park") warden police say that hate Choi Doha because hurt the person he loves ( i mean here is park chango)

And i think Jerry is a brother of a Park chango.

But of Jerry is a big mouse, maybe Jerry is a childhood friends at the orphanage

Rosayume Sep 03 2022 3:24 pm Mi-Ho is Big Mouse! If you go back and think about all the crazy and risky things she did without any fear, you will feel why I'm sure she is. All the signs tell me she is the one. All others are working with her and protecting her..

Sue Sep 03 2022 1:13 pm I don't think Park Noh is dead. Well, it's either the explosion was planned and he already left the building OR he really is dead since they no longer need his character. I also don't think he is big mouse. It can be Jerry. Or maybe Park Noh is big mouse and going forward they will be focusing on the chairman. There are still so many missing puzzles. I also think Doha approves of big mouse going on bail because he knows big mouse is after the chairman. Doha can careless about chairman since he is attempting to take revenge as well. I like the idea of the director of this drama. Director purposely does this to keep it interesting and for viewers to keep coming back. I do feel that this drama is going all over the place. One moment they're allies and the next they're rivals. Too much going on and certain parts I am confused. Overall, I've watched a lot of Kdramas and this is definitely one that I will remember.

chui Sep 03 2022 12:38 pm How the heck can they fit in the last 4 episodes the closure of everything that happened in episodes 1-12 ??? Will there be a closure or a 2nd Season? ?

chui Sep 03 2022 12:30 pm I cannot wait for the next episodes. I Need Answers! Lol! If No Park is really the Big Mouse then the writer used a reverse psychology to the viewers. haha. I was adamant that No Park is Big Mouse because it is too obvious to be him. There are a lot of scences showing he is the Big Mouse and ofcourse who would think that they will make it too obvious and maybe they are just confusing the viewers, but here it is! ugh! In the preview Changho's BFF's aura is something. I dont know hdkdlwhbwnmw!!!! XD just need to let out my frustration :D

Ezy.l Sep 03 2022 10:12 am Why No Park died??? I dont get what Doha think about revenge to Elder.

If Doha want revenge Elder, he must using Big Mouse too right? What kind Doha & Juhee thinking??? Very suspicious.

And Jerry is missing.

Still puzzle

sf Sep 03 2022 8:12 am What was the writer's purpose in making from a lawyer with only 10% success a convict and then to create the supposition that he is the big mouse?

SooY. Sep 03 2022 2:10 am In intro it is shown the mouse is going out of the puzzle and it came after that statue hiding a camera scene. If that's clue then mouse already went out the prison. That means big mouse is Jerry??? But isn't he is too young?

Sepanx08 Sep 02 2022 11:36 pm The plot is dragging and it centers only on the identity of big mouse. The writer is dragging the revelation since the drama will become boring once big mouth is revealed. Already dropped it at episode 9.

jr jr Sep 02 2022 8:28 pm for me big mouse is Jerry since day 1 it's obvious tbh. plus he's a top actor too, for sure they will give him a great character..

kdrama fan Sep 02 2022 8:14 pm Room Leader is the Big Mouse? What??? This can't be true!

CaffeLatte Sep 02 2022 8:13 pm I don't think it's No park, Big Mouse's first appearance should be cinematically cool and shocking, I think No park came to changho to tell him that miho's in danger.. but how did he know about his place? Jerry for sure is the right-hand of Big Mouse

Miho Sep 02 2022 8:11 pm This drama is best in making viewers think. So many twist and turns but my guess is Big Mouse is an organization so basically it consists of a lot of people. But my Miho girl is sketchy too. I don't think Chang Ho is the big mouse. Miho's father is sketchy too.

Small mouse Sep 02 2022 1:35 pm Drama is a Waste of time. Big mouth is a frustrating series. Nothing happens at all ... 11 episodes down ... But feels like watching ep 2. ????

Sue Sep 02 2022 12:05 pm Just got done watching ep 11. So shook. Tbis is only the beginning!!

Kaydrama Sep 02 2022 10:55 am Clue : No park's uniform number is the year of the rat according to chinese zodiac.jerry is his right hand man since jerry is a big fan or big mouse. My theory.?

Binggo Sep 02 2022 10:48 am Big mouse between No Park or Jerry

Big Sep 02 2022 10:47 am Big mouse between No Park or Jerry

chui Sep 02 2022 3:20 am I am thinking that Park Changho himself is the Big Mouse but... there's the same case scenario in k-drama entitled "Mouse" which I don't think they will copy. If ever that Park Changho is the Big Mouse this whole series is a joke. In that case they'll have no originality, which the viewers are expecting for them to do. I hope viewers won't get disappointed. ? P.S. the title was creative enough to have high expectations...

Miho Aug 31 2022 9:30 am For everyone who keeps questioning why the English title is "Big Mouth" when the title in Korean (Hangul) is 빅마우스 (big-ma-oo-seu), Korean also pronouncing "Big Mouth" as big-ma-oo-seu, so the hangul for "Big Mouse" and "Big Mouth" are the same. So the title actually both works for "Big Mouth" and "Big Mouse". But I think why they decided to choose "Big Mouth" as the English title instead of "Big Mouse" is because the main character in this story is Park Changho (the Big Mouth) not Big Mouse

Female_human Aug 31 2022 12:56 am The drama storyline so far is great, intriguing. Although the main character seems too develop to fast (from a dumb attorney that mostly losts cases to a smart calculated mastermind that can defend himself against the 2 big enemies in just a couple of episodes)

Also I still don't get as to why the english title is "Big Mouth" while the korean hangul says "빅마우스 = Big-ma-u-seu = Big Mouse"

fightstar Aug 30 2022 9:25 pm Park Chang Ho is the Big Mouse, This is another case of Jung Baruem of Mouse with a dual personality. He plotted this whole event.

Dongyeonfan Aug 30 2022 4:11 pm Thought this was made by same writer and director of vicenzo but turns out it's not. I love this kind of genre.. It shows us glimpse of what South Korean corruption really looks like. I know it's fictional but it's there

Fairuz Aug 30 2022 12:11 pm Why is the writer got no page? Is this her first drama??!! Wow!

Yaya Aug 30 2022 11:47 am tak kwang yeon is the big mouse, trust me

Nguyen Aug 29 2022 5:27 pm I think BM is the mayor! Maybe the 3 men and others stole the drug formula from his family and he is trying to get them back for it. It was mentioned that BM wanted the paper because he lost someone precious so him, was it his grandpa?? He may be trying to win over the Elder as a means to destroy him by using that paper as leverage.

BigM Aug 29 2022 12:27 pm @CaffeLatte...Wow, I love many of your hypotheses, absolutely right, hopefully many of our questions is answered before the end of the movie

Lily Aug 29 2022 10:56 am Well, Park Chang Ho is the real, the one and only "Big Mouse". Even before all these theories were made up, he was famous for being called "Big Mouth" which is i'm 100% sure that was given because it sounds similar to "Big Mouse".

Lee Jong Suk is the main actor, the drama is called "Big Mouse" then why the hell will he be not the "Big Mouse".

-Facts-

Lol jerry Aug 29 2022 10:18 am Why jerry has different tattoo? Lol

LEE Aug 29 2022 6:08 am Listen, Park Changho is BM! He's the main lead for a reason. It is not his lawyer friend Soon Tae, Miho, FIL, Jerry, No Park, prison guard, prison warden, Elder, Mayor Choi & wife and Prof Seo. Prof Seo is dead guys. There's no way Prof Seo's alive. Soon Tae, Jerry and No Park are all casted for comedy and to act as red herrings.

Mark my words, Park Changho is pulling an act on the viewers and fooling everyone that he is not BM. But he is!

CaffeLatte Aug 28 2022 8:42 pm Here are the missing pieces that we should think about 1. When the woman who told miho that she knows the place where Prof. Seo papers is, we didn't find out who pushed her.. 2. What did the room leader whisper to warden park while playing chessboard when he was hospitalized? 3. Why does miho's father look so relaxed as if it's not a big deal for changho to go to prison? 4. Who is the boy who Mayor Choi was flashbacking him at the fire scene? 5. How did Mayor Choi steal all these gold from Big Mouth and how was he able to hide them? 6. Is Changho related to the Elder by any chance? Since he was watching his live stream and was focused 7. So curious about the room leader's past life tho, and his lost daughter.. could be miho or Juhee 8. The warden said Big Mouth needs professor seo's paper because he lost someone very dear to him.. first, it could be about money.. he describes money as someone who's dear to him.. it could be the room leader or miho or choi doha.. or professor seo himself because i have a feeling that we will know about him furthermore in the next episodes.. and how did warden park know about big mouse's desire about finding the papers? 9. Where did jang hye jin go? It was told she's in itaewon... what could she be doing there? Could it be that she's with professor seo hiding somewhere? Or did she actually go to NY? 10. Why did the psychopath got closer to Guard Soo Chul when he was attacking the other prisoner? He has some grudge on him? Or is it something relatable? The guard also seemed concerned when the psychopath wasn't breathing 11. What was written in the letter when Jerry was hospitalized? And where did he go when miho saw that he wasn't in her hospital bed? I feel like he was meeting up with someone really important and the that's what was written jn the letter, and who's the guy who gave him the letter? He's one of BM.. i feel like it's the new doctor whom Hyun JooHee applied new, can't think of anyone but him. 12. Big mouth knows Changho from the past, it could turn out that he's the elder's grandson or something. Or he has an older brother ... I feel like I'm missing a lot.. hahaha

Yasgirl Aug 28 2022 6:31 pm I think all this guesses are too easy, I don’t think the mayor is BM he was treated poorly and all that but I think he is just getting back at them and trying to be the successor. BM might be anybody it might even be someone we have all seen but never suspected, someone in the background, BM is just playing with their heads but the question is why though there has to be a motive as to why. overall this is a very good drama can’t wait to find out who BM is.

Bm Aug 28 2022 4:55 pm Im having the feeling that Guard Gan Soo-Chu (warden) is the BM.

My big mouse fans Aug 28 2022 2:12 pm This drama really give me headache I think all the cast I suspecting it ??, they reveal in ep 9 who stole the money it’s the mayor, and the ep 10 PCH meeting the BM it’s a warden and he said he is the BM, so there is 2 BM, or I think this 2 is not the real BM, what a nice drama..

kdrama fan Aug 28 2022 12:24 pm It seems like Mayor has the best reason to be the Big Mouse. He has been treated poorly by the rich. They say he only became the mayor because of the rich family and so on. He wanted to get revenge on them to show them even if that's his wife's family. But at this point anyone can be the BM! Maybe I am the BM! :)

met Aug 28 2022 11:03 am in my opinion, big mouse is the room leader, Mi Ho is his sought-after daughter all along, and the little boy in photo is Chang Ho, so Chang Ho married Big Mouse's daughter.

Mama Aug 28 2022 9:19 am Suspecting the room leader too. When the prison warden was arrested, Changho told his wife to check whoever was angry and the room leader had that vibe

Betty Aug 28 2022 8:55 am What if Jerry is the real big mouse ? His name already suitable

OkParks Aug 27 2022 11:53 pm @addicted07 : yeah I agree with you...And guess what, I think Park nurse is Mr No Park's sister, Who can drug on Hyun Joo Hee's water bottle? besides Choi Do Ha her husband and nurses? Let's what happen next...

addicted07 Aug 27 2022 11:14 pm No Park head room leader is giving me big mouse vibes. He's always next to Warden and seems to control him in a way considering he can "read" people. Like how he "predicted" a jail mate death, telling Chang ho he's going to live a long life (him controlling his life), and tried to get the pills from the doctors (probably to see why the people are throwing up blood)

Crystal Aug 27 2022 10:55 pm The room leader is very suspicious. He lost his daughter, he can read tarot, he’s close to the head prison. Now he’s trying to get close to Miho finding about the ‘blood’ thing

bbiyongz Aug 27 2022 9:48 pm I don't think Miho is the Big Mouse esp if we want to consider that BM is an organization. Everyone has a tattoo, Miho doesn't have one. She's Changho's wife so if he has a tattoo, wouldn't Changho recognize it and realize it sooner the moment he saw that mark on the tarot card? Unless she really is the BM and because she's the leader, she can decide whether or not to have the tattoo. But still I don't think she's the BM. I can't find any motive as to why would she do everything she has done so far lmao.

Hongjossi Aug 27 2022 9:12 pm !!!!!!!!!!SPOILER!!!!!!!

From the previous episodes I guess miho is the big mouse..and if u think back all the clues can lead to her for being the BM..I think she is just pretending..and she truly loves changho..that's why Big mouse didn't do any harm for him..but who frames changho as the big mouse..that's the big question..I mean it's weird how they suddenly found money from changho's office..juhee is totally innocent she don't know whats going on at all..

Ray Aug 27 2022 8:46 pm I believe Choi Doha is BM, because he's the main character. hehe

Kshmii Aug 27 2022 5:58 pm I bet my hundred bucks, Miho is the Big mouse

oui Aug 27 2022 4:38 pm Me again here,i still keep guessing the same person as i mention before,i think about Tak Kwan yeon still this person is No.1 in my mind. if big mouse is in prison.it must be him. He is young enough to be drugs smuggle,his connection must be jerry ( jerry is his left hand cos jerry need money for his family and sister and jerry is like only con man like no harmful not that bad bad guy,he just poor and need money) chief prison warden is his right hand cos he is the head of prison, the one control all cctv and can monitor every single area in jail and he loves money so big mouse has drugs money and he may be deal with chief that he stole the identity of the death penalty prisoner.And i think its real story when he was in confess room he ask pch to help his mom and even if you rethinking about why pch became big mouse if you re watching its start from jerry point to tak kwan yeon and later Tky became over acting and start crying..because he is in death penalty row with rape and serial killer charge makes him looks so scary and nobody want to associate with him. his Mom was sick in hospital and may be she is a guinea pig of professor Seo Jae-Yong. and she die cos of that project.Prf may be did all this because the elder order cos his health is no good.He want to stay longer to control this town like the greedy king so that why he always looking for the heirs.

Tak Kwan yeon is,still i think he is my no.1 big mouse,after ep 10 i think his personality show up a bit he looks so scary and insane enough to be a drug cartel leader even crazy enough if you think about he can kill someone easy.i dont know im still long guessing write.Haha and for miho dad last time i think hes involved but now i think may be the lawyer instead of this dad cos i think its already ep 10 and the writer may be not that cruel to see miho and pch too sad i think his lawyer friend is the one who move money on the ceiling cos in ep 10 hes upset to know pch go to investigate without him ( he can spy and send news) The room leader is connecting to some case too i think big mouse is big organize and its all victim of the elder about urban development project before or even some of family became a guinea pigs so makes them connect together and revenge!

my choice no 2 and 3 is still the same last time im not cut off prf.Seo JaeYong or Kong JiHoon off specially Kong JiHoon ,hes not that stupid too and sometime he is mastermind and pretending but my no.1 after ep 10 still tak kwan yeon ( hes good acting and if he became big mouse as i guess surely he will be big star in the future from his acting) that my guess for today so i hope i will correct hahahaha

selen Aug 27 2022 4:22 pm new episode - new theory

okay so after findinf out the information that Professor Seo papera are important to BM because he lost someone i think BM is the room leader. Remember him saying that he lost his daughter…? That could be the reason… Also like we suspect BM should be in prison as well to control everything. That’s why he’s (the room leader) close with Warden Park, since warden park is « works » for BM… idk

sf Aug 27 2022 3:14 pm I don't understand anything from this tangled ball. Lee Jong-Suk's speak is too robotic, without any intonation.

Jillibean Aug 27 2022 1:59 pm I wish everyone would stop abbreviating the title to BM in their posts. I keep thinking of Bowel Movements. Lol!

jj Aug 27 2022 1:20 pm i feel the hospital director should have a bigger role, she has really little screentime but shes also one of the main supporting characters so i feel something is up with her

Bpatrawala Aug 27 2022 1:08 pm Big mouse is room leader, and he lost his daughter because of that paper. And miho and park changho aren't married lol why isn't ahe park miho ?

Aceil Aug 27 2022 10:30 am Okay, episode 10 is now out and i got my suspicions. I am just half way there and i don't think the prison warden is the real BM. I have my suspicions about the room leader. Remember when he got stabbed and sent to the infirmary. He whispered something to the warden and from then, they've been playing together. Lemme just watch it till the end and see what happens!!!

Fan Aug 27 2022 7:06 am Big Mouth is very entertaining! Ep 1 was just average and I think it lose critical mass there. From ep 2 onwards it’s a blast! Although it is categorised as noir I don’t think it is that dark. I thought it was very fun, very engaging and certainly very funny at times. There will be people who think this is not for them - those who don’t like complicated storylines for example. This will twist and fry their brains. But it’s so fun for others.

I love how in some episodes they will give that Lee Jong Suk moment to bring up the excitement but the truck scene reveal on ep 9 is simply another level up. It was so awesome and triumphant at the same time! And, look at the subtle changes of Lee Jong Suk’s character at every stage. Now he is no longer the cheeky and cheesy useless lawyer in ep 1 and 2 anymore. Love how the changes was slowly evolving.

AlisaMartins Aug 27 2022 5:17 am I still think Simply Choi Do Ha is Big Mouse, because you know He is handsome, hot, rich, and very powerful...I mean his character is Second Male Lead and you guys know why!! Hwaiting Gentle Men<3 (maybe I'm just a simple minded person and I'm not writer Haram nim so...! So Let's wait)

CaffeLatte Aug 26 2022 12:00 pm Ep 9 is out, it's not Mayor Choi, I'm still convinced it's Professor Seo himself, the one who met with changho at 8 pm will be jerry but he's not BM, I think he's just sending a message BM wants to say to changho, might as well the letter could conclude that doha must not be trusted, and that changho will have to warn miho about it, meaning that BM still refuses to meet with changho. Mayor Choi stole BM's properties before anyone does and that happened at the car crash and when the 3 thugs went to prison. He hired changho just for show and to keep them quiet, and he's the one who framed chango that he's BM now that all the golds and money is with him. I'm telling you, mayor choi knows who is the real BM and he just won't stay quiet just to sit in the elder's chair. It's such a shame the elder started to put his trust on him even more than his granddaughter.

Jang hyejin definitely told Miho about Choi DoHa, miho's face was suspicious to mayor choi when he asked about janghyejin and the paper, she knows.

To conclude this, Choi DoHa is just as bad as Gong JiHoon.. yet he's not BM. And just like how every single one who died from getting shocked then got alive again, it's possible that professor seo is still alive somewhere, with very good associates that he trusts.

Xhel sonne Aug 26 2022 3:56 am I just watched episode 1 - 8 but i cant find episode 9 please do you have link so i can watch.. thank you

Arif Se. Aug 25 2022 9:50 am I just watched 2nd episode and i am sure that big mouse is Jerry. He acted like idiot l, but he is actually so smart and cruel. I don't like to watch about life in prison. It's so cruel.

eri Aug 25 2022 9:34 am I personally think that Big Mouse is the prison guard who is always shown a lot taking orders from the Warden. I don't have concrete proof and it's all gut feeling so far. If ever I'm right, it would be so good tho lmaooo

lilac Aug 25 2022 7:16 am Jerry(Kwak Dong Yeon) ah I love you!! Hwaiting <3 Goodluck to your new drama with Go Sung Hee that will soon air in September!!!

Ezy.L Aug 25 2022 4:18 am I think the actor in ep 1 who was bury gold & on ep 8 who was moving the gold to Hospital is the secretary of Mayor. But is he the BM? Dont know.. i was analyst his physic and physic BM closest with the secretary of Mayor.

Althea Aug 24 2022 11:45 pm I think the father in-law is Big Mouse. He is a well-known, established, veteran actor in South Korea. I doubt that his role is merely a side character. I'm looking forward for a twist.?

Dutchess Aug 24 2022 6:34 pm This drama has lots of violence, so unlike of kdrama, but its lee jongsuk so ok, will still give a chance

Sister Aug 24 2022 9:53 am Amazing kdrama 'big mouth'. No doubt for LJS acting talent I watched almost all LJS drama except romance is abonus book. ...Btw, he is a fake international gang leader big mouse so it's acceptable when he says Big MouSE , Se not S . Can not wait for next episode. Hwaiting.

Waiting Aug 24 2022 9:18 am 2 more days for the next episode, can’t wait please hurry Friday.

Micky Aug 24 2022 6:17 am Now watching 2nd episode, so brutalIty in prison scene and some kind of mafia plot which so complicated. Actually I don’t like it but I am fond of LeeJongSuk’s previous works. Keep watching, let see.

Hoho Aug 24 2022 5:07 am For those asking for it to be available on Netflix, it’s actually being franchised by disney+. So go get disney+ subscription..

QueenM Aug 24 2022 1:04 am for my guess, its Jerry since he's still alive in episode 9 preview, and still there's no flashback why Jerry ended up in jail being a conman and the childhood story of Park Chang-ho. Hoping that Jerry and Chang-ho wouldn't end up being enemies toward each other. The guard also confuses me a lot coz the shadow of the man who dig all the gold bars is tall and well-built man. Netflix should air this so that people will also watch it , it will be a hit.

Ellen Aug 23 2022 7:59 pm I hope it will aired in Netflex

BiggyMouth Aug 23 2022 3:42 am Could anyone watch episode 8 again and look closely at the left finger of the person who set the Mental Clinic on fire, I think that is Big Mouse, he has a tattoo on his ring finger.. that is a big clue, Jerry doesn't...I don't think Jerry is the Big Mouse.

Hazel Aug 22 2022 3:09 pm To everyone who's here, curious, if Big Mouth is worth watching while still ongoing. IT IS! Every episode is thrilling. I had goosebumps at the end of every episodes. No exaggeration. It has just 8 eps as of now but these eps are just chef's kiss. Plus the actors are so d amn good. I suggest y'all watch this while it's still ongoing for suspense.

Godfred Aug 22 2022 2:32 pm Jerry means ‘little mouse’ and Chang-ho means ‘windows and doors’. Jerry chooses Chang-ho as Big Mouse and uses Chang-ho as a door to help him get out of jail”.

Sisterabenabayolo Aug 22 2022 2:18 pm Park Chang-Ho ( fake big mouse ) is the real big mouse or his wife

My big mouse Aug 22 2022 1:44 pm I think the real BM is from the orphanage and he knew PCH, I can’t wait for the next episode, Until this ep my suspicious of Being BM is always changing ??, my mind is always thinking.

kdrama fan Aug 22 2022 9:28 am I first thought Changho's father in law might be BM but now I think it could be The Mayor. Ji Hoon and others pick on the Mayor as non important so the revenge is to take Ji Hoon's money as BM.

who Aug 22 2022 7:22 am i think Choi Do-Ha is the big mouse he plan a revenge from his wife family cuz they killed ther

Draks Aug 22 2022 7:02 am Only watched 2 episodes but i think jerry could be the big mouse as the name suggest (tom and jerry, jerry = mouse) or jerrys elder brother could be PCO thats why big mouse.

QueenM Aug 21 2022 8:17 pm I think Jerry is still the big mouse, had watch ep 8 end preview and saw Jerry is still alive in the hospital, what if its Jerry all along? that he uses Chang-ho since he was a lawyer, and we didn't know Jerry side story why he's been in jail, we just know he's a conman. Just my thinking

BiggyMouse Aug 21 2022 4:51 pm Woah...This movie is lit! I have skipped the part of trying to figure out Big Mouse, we would eventually find out, now it's just to enjoy every scene.

Rosayume Aug 21 2022 4:15 pm When a drama becomes the number 1 reason why you wait for the weekend to come ? I loved Jong-suk since his first drama and I was sure this one would be a masterpiece. He is an excellent actor without doing any effort, his eyes can transmit to you his feelings and it's just powerful.

Now about Big Mouse, I will be happy if PCO is really him and that he is forgetting that fact. I would love to see this scenario becoming true. The one who is helping him now is not the real big mouse but his people and Go Mi-ho is one of them. I really feel that she knows that her husband is BM.

I don't imagine BM is someone not directly involved with him. Because after all what happened, why BM is still helping PCO??

The other theory is maybe the procecutor Choi Joong-Rak is BM. I feel this man is hiding things. He is the one who came up with the idea of taking PCO out of the prison to the Mental Clinic and he knows everything about their dirty activities.

Anyway, let's enjoy the suspense and forget who csn be BM ?

Gel Aug 21 2022 3:31 pm I think jerry is big mouse

crystal ball Aug 21 2022 2:33 pm From beginning of ep 1 we were told the city name. It is a fictitious city and not the usual Seoul. This is a reason for attention. We were told it is one of corruption and it was developed rapidly. We are now shown that it was build up by the elder and his compatriots, with likely corrupted means. That brings in the story of the Mayor, whose father, an employee of the elder, betrayed the mayor's trust because he dumped chemical waste improperly. Dumping of chemical waste at non approved sites can cause cancer to the people dwelling there (this happened in real life if you look it up). And the father should have done it under the elder's instructions. I believe the reason his parents and the NR group's parents are all dead is linked to the storyline.

This is why the mayor, though under the power of the elder, actually hated him and wants to seek revenge. The mayor may have married the girl for a purpose. I think they could have even lost a child previously and maybe to cancer too. That's why he had mentioned a few times that they get a kid and she was hesitant. Instead she wants to devote her life helping cancer patients even though the elder wants her to take over the empire.

The mayor seeked out Park Chang Ho and planned the revenge and therefore he may be Big Mouse.

The elder, on other hand, is old and looking for someone to take over the huge business. The mayor's wife declined him and he does not trust the mayor. Gong Ji Hoon is not good enough. He needed someone else. Park Chang Ho has said in the prison that Big Mouse is testing his ability. That brings to mind that the elder is trying to find a right person to take over. Is the elder grooming him to be the next one to lead the empire? And why Chang Ho? Could it be related to Chang Ho's real birth identity? Could it be Park Chang Ho is actually related to the elder? Maybe the elder is his grandfather?

The mayor told Ji Hoon that the elder is upset with Ji Hoon because the latter got Chang Ho out of the prison. That could be the case because Chang Ho almost died in the mental ward under Ji Hoon's hands. In prison the elder has eyes to watch over Chang Ho and make sure he could test his ability and not come to any harm.

There are many other reasons that make me derive to this possibility. But conclusion?

Big Mouse could really be the elder or maybe the mayor.

kdrama fan Aug 21 2022 10:32 am I still think it's Miho's father as Big Mouse. Is Jerry still alive?

LJS Oppa Aug 21 2022 9:03 am Very interesting drama. Every detail since episode 1 is important. All the main casts from Chang Ho’s family/team to his prisoner’s group played well. Welcome back Lee Jong Suk oppa. I look forward weekly for the big reveal. You’ll even crack your brain just to think what will happen next. Woah!!!

Xxxx Aug 21 2022 7:13 am Chang-ho is big mouse. Big mouse is his alter personality. Hehehe

Ok Aug 21 2022 6:08 am PCH is BM. He took drug like the one in The Veil where u lost some of your memory. He's target is the hospital secret. Jerry is he's right hand. The guys with tattoo are the kids he took care in orphanage. CDH is the one targeting NR. PCH/BM use CDH and NR.

The drug they give him, Peace is one of his creation. The milk is fir his experimental mouse. He create drugs.

Lalallalalalalalala Aug 21 2022 3:56 am I think Choi Do Ha is the big mouse

Dramafans Aug 21 2022 3:31 am I think Jerry is just the right-hand man. Idk why but I have a feeling Big Mouse is either Kim Soontae or Go Miho's dad.

My BM Aug 21 2022 1:26 am I can’t wait for the next episode, this is really a great drama,

Guje Aug 21 2022 1:12 am After watching episode 8, I'm convinced that Jerry is Big Mouse.

magsie04 Aug 20 2022 11:40 pm so, big mouse is an organization who'd like to go against the elder and NR forum i guess. just like an organization looking for a spokesperson, chang ho happened to be the one chosen maybe bcs of his unrelated background to the families of chaebol or he's actually very related since he's an orphan, no one knows his origins yet.

Darkeyes28 Aug 20 2022 3:33 pm At this point, I gave up guessing who is Big Mouse. I will just wait until this drama unfolds the story

ChickenNoodleSoup Aug 20 2022 2:47 pm Bruuh ,

I cant guess who Big Mouse is. There's a lot of possible, qualified people. Dang.

After watching the Episode 8, I have a new hunch that, Big Mouse is someone related to the Hospital. Due to seeing where the golds were hidden.

I can't wait for the next episode and the episode for the next weeeeeeeek.

selen Aug 20 2022 2:01 pm wow, ep 8 was amazing !!! Reading these 2 comments, y’alls theory aint bad… It could really be that Professor Seo is Big Mouse. As I already mentioned some comments down, big mouse isnt a person probably but a group/organization (for example the cop was one of them hence to his tattoo) and the head is Professor Seo…

Nah bro Aug 20 2022 2:00 pm There is criteria for Big Mouse 1. Rich 2. Unexpected

Based on that criteria I think big mouse is Park kwang jae because has a gold teeth (rich), he is the one who see and able to help Chang Ho on episode 8

Ezy.L Aug 20 2022 1:26 pm I think who is BM related with Chang Ho orphanage. That people who helping Chang Ho has different tatto that means BM is not just a person, but organization too. Remember that Chang ho always give milks to orphanage. The BM either Chang Ho or someone has live in the same orphanage with Cang Ho.

For Mayor Choi i think his role different and to mess our focus who is BM. For the first time Mayor Choi hire Chang Ho i think for fall down Elder & i think Mayor Choi knowing that his wife who was murdered Seo Jae Yong, but he just told to Chang ho that Gi Hoon was the brain of murder.

Mayor Choi has grudge with NR , especially elder. But not the BM (i think? Hehe)

The suspect for my opinion is Chang Ho, Guard gan seon chul, tak kwang yeon, Jerry, secretary of Mayor Choi & Secretafy of elder.

CaffeLatte Aug 20 2022 12:07 pm After watching ep 8, I'm strongly convinced that big mouse is Professor Seo. The director made our suspicion around everyone in the cast based on their actions and hints, while we still don't know what Professor Seo's deal with his chip, we also don't know how does he know ChangHo in the first place. I'm guessing both him and changho were friends back in the orphanage, now that changho's past was all about the orphanage then him meeting miho and her father, he must know him from before, and he's the one who chose him as the lawyer for the 3 annoying prisoners so it was planned ever since he took their case. He applied him because it will be easy to control changho since he was called big mouth at his workplace. Also, who's the one that's been drugging the prisoners? and who's the one who drugged changho in ep1? It must be someone who acknowledges medicine so it might be Professor Seo cuz he's a Doctor.

After all I don't think Professor Seo will die this easly, he has many acquaintance and he's a billionaire, everyone needs him. And I have a feeling jang hyejin knows that he's the real big mouse, and he keeps giving her orders to do as he says.

I think.. Aug 20 2022 12:01 pm I think the BM is someone between miho, miho's father, sun tae (chang ho's friend), and mayor choi.

From the very start, BM had already targeted someone incompetent to 'handle' the 'game', and these people are the one who knows changho is incompetent

And sometimes, there IS a drama that reveals the 'answer' or the villain in the first ep, and they go twisting it around in the remaining eps to make it fun..just sometimes, cuz Memorists didnt reveal the villain until the last ep lol

Dumas Aug 19 2022 10:39 pm From the trailer it looks like Chang Ho will be able to escape the mental institution and then possibly launch a come-back revenge (Jerry could die tonight in the hands of the bad guys). I guess Park Chang Ho will be the one to find the buried gold and then it’ll be another setting. Haha… the revenge will start soon!

But I think in the end Park Chang Ho will choose lawful justice. This is something Lee Jong Suk holds close to his heart, and a common theme in his dramas after 2014. Won’t be surprised because this drama was an idea he came up with the director.

The hint of the book which hides the phone is important. The Count of Monte Cristo - based on a true story. Take a look at the story and you’ll know where this drama draws its inspiration.

Phyllis Aug 19 2022 7:17 pm At this point i just can't think anymore ?

mel Aug 19 2022 3:04 pm @Big PP

omg !!! your theory is very interesting , i want to know the other reasons tho ???

gie Aug 19 2022 10:02 am choi do ha is the big mouse. jerry (maybe his actual name is seo jae ri? family of seo jae yong?) is his accomplice. gong ji hoon and joo-hee were the ones behind the death of seo jae yong?

Pocket cheese Aug 19 2022 6:17 am It’s like watching a movie every week. The directing, acting and cinematography is really good. Can’t wait for next episode. It’s better than Extraordinary Attorney Woo imo.

Dizzy Aug 19 2022 12:05 am I think Big Mouse is Room Leader. Jerry is his minion. They work together to train Changho as Big Mouse because changho is a Lawyer. They need a lawyer to help Room Leader's missing daughter case. The room leader is the one who sending Changho the tarot cards. Since he is a fortune teller, he's the only one who understand the meaning of all cards.

Big PP Aug 18 2022 10:55 pm Tak Kwang Yeon is Big Mouse

He is the one who did not died during the isolation. He didn't kill Park Chang Ho He have mom that have leukemia or something, probably related to the doctor journal. The doctor is experimenting with their patient for new cancer medicine and his mom is one of the victim (remember the episode where there is a floor full of patient that rejecting restitution?)

I have many other reason but wouldn't disclose it bcs it will be a big spoiler for yall

Mari Aug 18 2022 4:53 am I feel like the room leader is the big mouse or smth.

Lily Aug 18 2022 1:16 am Hey @Miho

Lmao! It's not Miho!!

Reasons why Miho is not Big Mouse:

1) The drug buyers namelist given by Mayor Choi, was relayed from Miho to Changho. Miho could have edited the names. ---- Did you see how is this romcom and turns into a tragedy at a second? Miho don't want to lose Changho and even Chango to her. Jerry is the one lure Changho and provide correct paper. It's a guy not a woman. She's just quick witted main lead. Remember Flower of Evil? I just reminded her character to the FL.

2) Burner phones, gold bars, drugs etc were found in Changho lawyer office. Only Miho and FIL could set it up. ---- We all know it was a setup from the start and I believe the Mayor is involved with this.

3) Changho had to borrow from loan company, so he’s not Big Mouse. FIL is aware he borrowed. Only Miho is kept in the dark. --- Lol! The two main leads are just normal couple.

4) Miho is a nurse and Big Mouse has knowledge of drugs (to swap drugs and drug Changho). Coincidence I think not. -- the point here is Miho is a Nurse because they're also against with the hospital she currently works but nothing else just helping her husband get out of the jail.

5) Miho seems so fearless at times. She announced to the public that she got hold of Prof Seo’s papers. -- we all know she's quick witted from the very start. But she's not that evil why would she let her husband get maltreated in the Prison?? Crazy!!!

IMO it's not Miho It is someone closer. And I believe, not only Jerry reports to that person.

Jonel John Ali Aug 17 2022 9:01 pm The movie was extremely amazing and beautiful, especially when the events will be going on and a lot of questions about who is the real big mouse. Mainly, all the characters are very wondrous, especially acting their different rules of events # good job and God bless you all.

Where’s the Cheese Aug 17 2022 7:16 pm @miho

In ep 6 they answered it.

If she’s the one there’s no reason for her to interrogate him if her husband is big mouse. The list she handed him was the wrong list and Park explained that he got the right one through the Tarot card.

Personally I think the tarot card is an awkward move by the writer - unless it’s a bad excuse that he came up with to lie to his wife.

Sten Aug 17 2022 2:26 pm Good as didn't expect anything much because few jail dramas around but took by surprise, I like.

Miho Aug 17 2022 1:57 pm Some of the viewers are criticising Yoona’s acting and the character she’s playing in the drama. I watched until episode 6 so far. I have a feeling it’s all an act on Miho’s end. Miho is the real Big Mouse. So this drama is essentially about the Big Mouse and Big Mouth couple!! (If my head cannon comes through, I’m so watching this drama to the very last episode!!)

Reasons why Miho is Big Mouse:

1) The drug buyers namelist given by Mayor Choi, was relayed from Miho to Changho. Miho could have edited the names.

2) Burner phones, gold bars, drugs etc were found in Changho lawyer office. Only Miho and FIL could set it up.

3) Changho had to borrow from loan company, so he’s not Big Mouse. FIL is aware he borrowed. Only Miho is kept in the dark.

4) Miho is a nurse and Big Mouse has knowledge of drugs (to swap drugs and drug Changho). Coincidence I think not.

5) Miho seems so fearless at times. She announced to the public that she got hold of Prof Seo’s papers.

Poche Aug 17 2022 12:26 pm Tom and jerry cartoons.

Is jerry the cat or the mouse in that cartoons?

Naabi Aug 16 2022 11:47 pm Wait, I forgot that psycho, why did he try to kill Changho, when he knew he was going to help, do you think he has to do something with BM.

Naabi Aug 16 2022 11:43 pm you know, I think either jerry or the Room Leader is the big mouse, like room leader is so observant, he is quite and maybe he is testing or you can say teasing Chong-ho with her daughter's story, or maybe her daughter's incident turned him into Big Mouse. And about Jerry, I think he is just trying to hide himself in jail, he is trying not to go on death sentence, and he is just trying to stay low, whatever, can't wait for next episodes.

Ucup Aug 16 2022 7:51 pm I think the big mouse is close friend who call BOS for the first time, he have mouse tatto on his hand. Overall this drama make my head work hard haha good job team.

Chimmy Aug 16 2022 5:39 am I think Big mouse was revealed in the trailer for ep 7.. Jerry may not be BM but he definitely has something to do with him/her. This drama is worth everything.. 100/10 for me. Lee Jong Suk, hwaiting!!

shaiveloves Aug 16 2022 4:20 am I think Mi-Ho his wife is the Big Mouse. When she gave the list to chang- ho she altered it with the right ones. The only reason why she framed him to be Big Mouse is to save him from dying at prison. I think her message was keep your self alive is an indication that he must live like big mouse in the prison. Additionaly in the scene where she told him she has a lot of money and will pay for his tuition in college. Lastly, i think she has a watcher inside prison that reports to her everything.

Big Mouse Aug 15 2022 9:05 pm I'm tired guessing who is Big Mouse to the point where i'm sure Big Mouse is me, you, us. The audience are Big Mouse. We are all evil. hhaha... There's a reason why Changho always look at the camera in the end of every episodes. He thought we are Big Mouse.

Jillibean Aug 15 2022 8:13 pm I had a similar thought about the father's role in all this but I really hope it's not him. I like that veteran actor and don't want to see him turned into a bad guy.

kdrama fan Aug 15 2022 7:47 pm @hikari - that is so crazy you were thinking the same thing I was. I decided to watch the 1st episode again and thought the Big Mouse has to be someone Changho knew before going to prison. And we always see Miho's father defending Changho.

Hikari Aug 15 2022 7:41 pm What if the real big mouse is Miho's Father? To save Park Changho's life, because he know, if Changho not 'become' Big Mouse, he'll die.... His 'right-hand' in the prison could be Jerry and Gang Soo Chul, and the other clue is Choi Doha ever felt cheated by his father, still we still expecting, nice drama btw

the real big mouse Aug 15 2022 11:18 am I am predicting the big mouse to be Mayor Choi, and Jerry as the "little mouse". Jerry could be related to Mayor Choi too. Anyways, this show is really interesting!

Madapaka Aug 15 2022 9:18 am Lee Jong Suk can never be the Big mouse since big mouse is a vile person. After watching hundreds of dramas, I observed that bad guys always dies or suffers at the end of the drama. It doesnt matter whether you are the main lead or not. If you want a sad ending like mouse, Kill, and penthouse then make Lee jung suk as the Big mouse. It seems like all writers believe the "an eye for an eye , a tooth for a tooth". The end will never justify the means. With that mindset, I'll cross out Lee Jong suk as Big mouse. I firmly believe that Choi Doha is the real big mouse and Lee Jung Suk as Big mouth.

Mari Aug 15 2022 8:09 am What if it is really just a mouse

Just want to say something Aug 15 2022 8:07 am I think the real big mouse won't be revealed till the very last two episodes. Through the episodes before Changho will begin to believe and behave like big mouse like the pretending game becomes true. And the end will be real big mouse vs Changho who believes he is big mouse. Either big mouse has made his real enemy or he wanted Changho to be the nest big mouse. The only thing that can save Changho from losing himself is his wife.

Or the other plot that Changho has splitted personality and he is the real big mouse.

Xxxx Aug 15 2022 8:05 am Jerry is a mouse therefore jerry is big mouse. Hahaha

Hamed Aug 15 2022 1:09 am The room leader is the real big mouse. Or he knows who real big mouse is. Either way he has something to do with the rest mouse. Just a hunch

Jillibean Aug 15 2022 12:24 am SP, I am not sure it's a case of split personality, Kdramas don't often utilize that type of story (losing one's memory, on the other hand, has been done to death in Kdramaland!). I think, rather, the writer is just trying to show character growth; with each new harsh experience his character deepens. I do hope the whole drama isn't set in the prison till the end. Frankly, I'm getting a bit sick of it. I would like to see his character in the real world too, becoming a better lawyer because of everything he has experienced. Not to mention a better husband. His wife is a lot smarter than he is. That bit with the phone in the hospital, where she had taken care to save a picture of the original prescription, was brilliant.

SP Aug 14 2022 8:52 pm Its a great drama but i noticed a few plot holes from the start, which I hope some of you can help to answer.

1. The drama started off as Changho being a completely different man. Timid and full of big talks, which is how he got his name as big mouth. Has his father in law as his assistant since he operates his own law firm. Was offered this deal from Doha and stupidly went to look for Jihoon, trying to threaten some money out of him (which is smth I wouldn't imagine the real big mouse doing). Drank a drugged drink and got sent to prison. 2. Once he was in prison, he attempted to commit suicide / get someone to kill him many times. Not to forget, he even died for a few minutes when he got hanged by the VIPs. 3. After his attempts to die failed, he thought to himself that the only way to survive and protect Miho is to PRETEND to be big mouse while he's in prison. There was even a scene where he punched the other prisoner and in his mind, he told himself that he didn't know that his punch was this strong. 4. Right now, everything that he's doing, his thoughts, his charisma and his actions points to the fact that he could be big mouse himself? It doesn't make sense for someone to have such a drastic change and power to influence. He even THINKS completely differently like a super smart guy, unlike his 'real' self as a 3rd grade lawyer. 5. He used to love money alot, but when he saw the briefcase with money, he didn't even flinch. Many things just doesn't add up.

My only logical self explanation for his case is he could have split personality?

Jillibean Aug 14 2022 8:42 pm I'm less interested in who really is Big Mouth, and more interested in why Park Chang Ho has such a terrible lawyer in Kim Soon Tae! He should have been able to prove right off the bat that Chang Ho, his client, had his drink poisoned with illegal drugs, which caused the car crash. You shouldn't go to jail if you were set up in that way; he should have had that woman arrested who gave him the drink and then forced her to incriminate baddie Kong Ji Hoon. Problem solved right away. Chang Ho would lose his law license because of his foolish attempt at blackmailing Ji Hoon, but at least he would be alive and not have to suffer in prison.

As for the identity of Big Mouth it's usually going to be someone you least suspect. Typical late plot development in these kinds of stories.

Merrily Going Around Aug 14 2022 1:37 pm I don't sense Jerry as the big mouse. The 'Jerry' in Tom and Jerry has always been the little mouse. But I have a feeling that he is a mole planted next to Chang Ho to monitor him. Not that he is a bad guy. In ep 5 and 6 there were enough scenes to show his concern of Park Chang Ho actually stepping into the dark side. Maybe he is working for the Mayor. Or he could even be related to one of those bad guys out there even if he himself is not a bad person.

If Park Chang Ho is the real big mouse, wouldn't that mean he is not the usual protagonist since big mouse deals with drugs?

The mayor has several points to link him with the possibility to big mouse. He can easily access information of the hospital's secret because he is the husband of the director, he is a member of NR Forum, he is the mayor so he has power over the prison warden. So he really has links to everybody. If even Jerry is related to him then he would have direct connection with the prison. The mayor was also the person who approached Park Chang Ho first and dragged him into this. His trust for his family was betrayed when he found out his father was doing something really bad. He also said that to be a big con man you have to first con your closest one.

Comfy Noir to Watch Aug 14 2022 10:51 am The show that would never stop me guessing who is Big Mouse. Greatest Show in 2022!! Yes, i'm calling it now because the show is getting better and better. All actors in this show have good acting. The writing, the directing, the plot, the cinematography, the camera work, the details, even the graphic design, everything else is cool!! I admit, it started slow, then it goes dark and painful in a good way. Now it's Fire..!! The ending of each episodes is always good. We are only at 6 episodes, but it's been so good. We able to feel what Park Changho's feels through Lee Jongsuk's portrayal as Big Mouth to Big Mouse. He has a range, a look, attitude that only few korean male actors have. Yoona's role as Miho (Changho's wife) also satisfying to see. Her role is not like other annoying-clumsy main female characters out there. She has mature and brave personality. Such a queen behavior. The other supporting actors' acting also fun to watch.

Well, let's get to my theory of this show. After watching episode 6, I think it's safe to say Big Mouse is Mr. No Park, the Room Leader? He knows how to read tarot cards that he uses to comunicate with Park Changho. He needs to find his lost daughter so he ask Changho about it. He assures Changho whether he is the real big mouse or not while they're in prison clinic. Then, changho says yes. So, he helps Changho become the Big Mouse at full force by sending all those tarot cards, magics and deaths. Obviously, Jerry knows about this. So, he plays along with him to train Changho as Big Mouse. But even if that was true, I still need to know how Big Mouse put all the big mouse evidence in Changho's office. There are many many mystery i need to solve. I love it. Keep it coming..!!

kdrama fan Aug 14 2022 8:20 am Reading so many comments here, many of you have very good imagination in who could be Big Mouse. I think anything can happen as the writers can make changes. In the beginning, I thought Jerry is Big Mouse but I think that would be too easy for the writers and it is too early to show us who BM is.

It will start to make more sense by episode 13. It is too early

The Great Pretender Aug 14 2022 5:59 am At the moment I think this few are suspicious:

1. Park Chang Ho 2. Noh Park 3. The Mayor 4. Hyun Joo Hee

And maybe even Tak Kwang Yeon or Jang Hye Jin.

I think the writer purposely leaves enough suspicious elements for most characters. But the storyline of NR forum and the hospital would definitely have to come together.

FF Aug 14 2022 2:55 am I think if we watched 'Mouse', it is possible that Chang Ho is the Big Mouse, if not how he gets the list of drug addicts. He conceal his identity by becoming an unpopular lawyer. N who are able to hide all the money in the office???

The second theory is Miho, his wife. Because only she has the lists n she might have exchange the names herself as we know fake names were given by Doha. One more who easily has cyanide if it's not someone who work in the hospital.

Doha's wife is the one who is said to have an affair with Prof Seo. It is confirmed.

popi Aug 14 2022 2:14 am Jerry sus bcs he such a liar being a fan of BigMouse other wise he is his slave a.k.a little mouse Jerry. Doha sus bcs he plays as good char meanwhile he such a liar by being a Mayor by cheating with money. the people who told that he is BigMouse aren't the real BigMouse such as Cangho and Warden YongCab bcs it just a lie for bragging. So, Cangho and YongCab no sus. Prof. Jang Hyejin sus tho. She knows about Prof. Seo's paper, the dasboard camera, and she has an affair. She has conflict with her husband Dr. Han. The Waiters on eps. 1 who gives Cangho coffee is sus, where she gets the drugs from???

Letss Aug 14 2022 2:00 am Im thinking it’s the guard who is big mouse. What if he changed his work clothes to pretend to be an inmate so that chang ho would think BM is an inmate and not suspect him…and Jerry is probably working under BM and has no clue how he look like..orrrr Chang ho is really BM. Got me thinking about the kmovie “the witch” where we thought female lead was an innocent/weak person but towards the end we find out that she is really strong and was pretending the whole time…Maybe this might be the case too. Just my theory hehe

Big Aug 13 2022 9:48 pm The room leader man maybe the BM, Another weekend torture ??waiting for ep, jerry may know who it is every episode I always guessing who Real BM is?this drama really good.

Annashadow Aug 13 2022 9:10 pm I just want to who the Big Mouth actually. If you guys have opinion just comment below I want to know and I like to read about you guys opinion. Because that really interesting to guess who are "Big Mouth". Jerry may know who are really Big Mouth.. damnnn need wait for next week episode.

Hana Aug 13 2022 8:29 pm Yesterday’s episode started to shed some light. It was not the most brilliant episode but oh my, when Lee Jong Suk smiled in this episode I actually felt chills~ ~ He Was So Scary!! How can such a pretty face gives off such terrible feel?

oui Aug 13 2022 7:48 pm i think big mouth is Tak Kwan yeon. the murderer who isolated in prison now,He work as a team with jerry and the guard and some connection with jail leader then he can monitor everything too and i guess he has something related with hospital case and Seo Jae-Yong the professor, his sick mother is behind the secret door,He need to do everything to make her better condition as the early episode he cant control himself to talk about his sick mother. I just guess! And Miho dad is involved too cos he has the key at the office( to moved the money on the ceiling in that quick time ) or even seo jae yong is not dead yet,he set up this plan with some of 3 in vip gang and control behind it.it like ghost control and nobody will point at him..and something to do with card leader too everyone who involve big mouse always in hospital and if not the murderer is big mouse i guess it Kong Ji-Hoon himself is Big mouse cos he take care money for older the money that lost is not his money but older money right? so my guess will be this ??

Tom Aug 13 2022 6:43 pm My opinion: I think Big Mouth & Big Mouse is one. Park Chong-ho has a medical conditon called DID. A condition that has a 2 identity. I have watched some Kdrama like that. BUT… still this drama is very unpredictable because there’s Jerry that complicates my opinion. Theres something about him that i started to think deeply. Very unpredictable!

QUE Aug 13 2022 6:26 pm I just finished 2 episode in a row last night. Wondering how Chang Ho can maintain his hair in shape in the prison? Anyway its a amazing drama

Crystal Aug 13 2022 11:24 am According to the title, big mouth, which means a person who likes to brag, very suitable for the character who lies and acts as a big mouse, so Chang Ho isn’t the real big mouse.

I think the real big mouse is outside the prison, and Jerry (as his name is just a small mouse) is a accomplice of big mouse that sticks to Chang Ho.

The big mouse maybe someone who wants to judge the people who kill Seo Jae Young, then he put Chang Ho as his minion.

There’s a possibility that the writer won’t reveal the real big mouse in the end too.

Well, can’t wait to see it till the end. This series is so good! Brilliantly scripted!

Shin hara Aug 13 2022 9:01 am I have 2 theories about who Big Mouse and why he helps Chang Ho in jail.

First theory, I think Big Mouse is someone in jail who has blood relatives or relationship with Seo Jae Young. Brother maybe and he knew Park Chang Ho is in jail because he tried to uncover the truth about his borther's death. And he wants to get revenge by putting Chang ho as his player. But in the end, Chang Ho forgets his true intention, he gets more and more evil. And becoming Maniac. At the end of the day, the real Big Mouse will turn his back on him. And becoming his enemy. But Chang Ho will finally realize that what he did is wrong and hurt his family. He becoming good again and make pact with the real BM Probably : Jerry a.k.a Seo Jae Ri

Theory 2 : Big Mouse is someone who truly care for Chang Ho. He realized that if Chang Ho get in jail by people who did bad things, he might get hurt till death in jail. So the only way to save him is by putting Chang Ho as Big Mouse. He knew people scared of him, he knew he stole money from the crazy riches. And he can act from the outside and inside jail (by using spy and killer maybe the mysterious guard. Thats why people who do bad things to Chang Ho getting killed mysteriously) Probably : Father in law a.k.a Miho's dad

I am 100 percent sure Big Mouse isn't Chang Ho As the title itself already revealed it's point Park Chang Ho is just a Big Mouth

Arie Aug 13 2022 8:49 am After watching ep 5, I still think Big Mouse is Choi Do Ha for some reasons…It is obvious though!

Little rat Aug 13 2022 7:55 am Big mouse will be someone that you least expected. Kwak Dong-yeon

Tholore Aug 13 2022 7:24 am After watching ep 5 I'm convinced Chang ho is big mouse I think his life with Miho is supposed to be a font to hide his real identity and he's became obsessed with solving the hospital case cos that's what put him in the limelight and revealed his identity There are still so much we don't know yet the hospital is definitely hiding something mysterious All in all this drama is lit

Cj Aug 13 2022 4:48 am After the Drama 'Mouse' I've never been this hooked to watch and wait for the next episode. Everything is so good. Also, dramas with a mouse in it, can't really be trusted LOL. I'm pretty convinced that Chang Ho is really Big Mouse and I think Ko Miho is hiding something that would turn the tables around

Cindee Aug 12 2022 8:55 pm This production is awesome! It’s of good movie quality. Story is tight, script very good, director good and actors are all great! It’s not at all boring. It’s so exciting and I feel myself immersed in the plot. It’s a long time most Korean dramas have been very boring and I almost stopped watching. So happy this comes along. They should win daesang. Especially the male lead. He’s very famous here and his shows rarely disappoint.

I don’t think it’s Jerry.

There’s reports that there’s 3 groups of producers and Lee Jong Suk is one. They have already made a lot of money by selling the rights.

Ala Aug 12 2022 7:25 pm I have big feelings that the events will turn on ep8 just like mouse , and i feel like chang-ho has Schizophrenia

Darkeyes28 Aug 12 2022 3:09 pm Chang Ho, probably has DID. After watching episode 5, I am convinced that he is the Big Mouse.

Rosayume Aug 12 2022 1:47 pm I'm so confused after ep 5 ? Chang-Ho is no more talking to himself like the first episodes, no more monologs :o so it's hard for us tell if he is really lying about being Big Mouse or not xD It's getting exciting to watch and curious to know all the story behind. Soo much mistery. I think the writer did it on purpose, he wants to confuse us as much as possible ? I can't wait for the next episode <3

nora Aug 12 2022 1:29 pm atp i kinda also have the feeling that Chango-ho is Big mouse. Maybe it‘s really because of the accident that he forgot his memories and doesn‘t know that he himself is Big Mouse. Also whats in that secret room in the hospital? Also does the mayor‘s wife have the papers from doctor Seo Jae-Yong because she‘s wearing a cross, maybe even The cross..?? I love this kdrama so much!! No matter the outcome, this is such a good kdrama !!!!

rnnldsm Aug 12 2022 12:29 pm I really think Kwak Dong-yeon is a real Big Mouse. He even named himself as Jerry and had a tattoo on it in his wrist.

Park Chang-ho also said that the Big Mouse might also be in the penitentiary with him because ppl fighting against him kept dying mysteriously, which is in favor with him.

It's very odd also that everything was in favor of Chang-ho's fight. And Kwak Dong-yeon's character is very strange right from the start. I think he's helping Chang-ho secretly to keep his identity.

Well, it's just my opinion. If that's true, I hope they'll be fighting on the same side at the end.

Aqua Aug 12 2022 12:23 pm Excellent drama and top acting

Disan Aug 12 2022 11:29 am My Im-Yoona’s character named Go Mi-ho similar like Gumiho (mystical fox in folklore who likes to fool human). Is it a hint to tell us that she will fool us around? Interesting haha.

KdramaFan Aug 12 2022 6:00 am Well 3 episodes down and we are still where we started off. No History behind Big mouse .... Suddenly LJS is hired ... ..drugged. ... Framed and Jailed. I feel things just do not connect at all .... Nothing special at all apart from cast but their acting too is Blah n dead. Money found ... Doctor dead ... Prisoners fighting amongst themselves ... Its like too much going on but nothings actually happening where i can say Wow ... Just a blah drama fr me. Will watch ep 4 ..... N then decide whether to continue or not.

15 hours b4 Ep 5 Aug 11 2022 4:04 pm Maybe, Park Chang Ho is the real Big Mouse who stole from them rich. That explains the man in the gold dumping scene in ep 1 whom I also believe looks like Lee Jong Suk.

However, the car accident he had due to being drugged by one of those bad ones, caused him to forget his secret identity of Big Mouse. Now, he doesn't remember he is Big Mouse and yet is forced in jail and has to pretend to be Big Mouse just to save his family. The one he is trying to pretend is actually he himself without him knowing. Park Chang Ho now has to use his Big MOUTH skill (from being a failing lawyer) to convince everyone he is Big MOUSE.

This guess could explain why money and criminal tools were hidden in his office - he probably forgot everything associated with Big Mouse due to the accident. Though of course those things in the office could easily be a set-up from any of the bad ones. Or, he could indeed have a split personality. That can explain the part when he was surprised by his own strength (though of course if you have never hit someone in your life before you probably would be surprised about your strength or lack of). I don't really buy the split personality theory though.

Been thinking about the 3 (or 2?) young neighbours. They are listed on the cast list above. If their appearance is only for comic relief to showcase the relation of the married couple, that one-off needn't be listed. They appeared in a very recent interview too. Could they be the ones to help Big Mouse Chang Ho do the NR forum job?

May Aug 11 2022 3:57 pm I really love this series.. So excited for more episodes...

Yoon kay Aug 11 2022 11:35 am My prediction, Big Mouse is either Miho or Jerry Just those two. The reason why Chang Ho needs the list is because he wants to make sure that the Mayor is a good person and can be trusted.

Big mouth Aug 11 2022 7:24 am It's gonna be a twist if miho is actually the big mouse hahaha I'm just having that thought when i read this article with the pic of main characters including miho and the caption is "one of the main character could be the big mouse" sth like tht so i was thinking its also possible miho to be the big mouse since i remembered the drama Memorist whom the villain is a girl (which has never been revealed until the final ep and i was mad hahah i mean like how could us even guess that?!) But there are many characters that are sus tho like jerry, and changho himself so i cant guess it yet for now

Luna Aug 11 2022 7:08 am Friday! Friday! Friday! Why is Friday coming so slow?

This is a very high production. Makes me worried if it’ll continue to be so good or will it become bad midway like lots of k dramas.

At this moment there’s so many suspects but some things are for sure. Money was stolen from a group in N room - from corrupted people with money and social status. There’s a mysterious elder that these people fear. The hospital is involved in shady business, and the judicial system and prison are also corrupted. Haha yes it seems like they are in serious need to have someone shake up this city. So, is big mouse a hero or just the bad eating the bad?

The drama’s directing and cinematography is very good, so is the acting. People are really missing out not checking on this.

jaehan Aug 11 2022 6:58 am I have no interest watching K-drama lately but i try to watch this one because i like the cast. Didn't expect this is so good! every episode always make me curious abt what will happen next >_< There's a guess for who is big mouse is but i try to enjoy the plot and not get distracted by my guess haha

Lily Aug 11 2022 5:19 am Everyone seems has different secrets in this show. I think the one who framed Changho as Big Mouse then put him in jail is not Big Mouse himself. Then, there are these people who hid Professor Seo's Paper somewhere from Changho and his wife. The secret of who is Big Mouse. Then, there are people who are secretly helping Changho become Big Mouse in prison. ALSO.. is Prof. Seo really died? yes, i saw him dead, but there is any funeral i should see? That's why i think every characters in this show looks suspicious. We are suspecting everybody because THEY ALL have secrets. If Changho is the Big Mouse, well then he has got to have Magic. lol. because I don't want to agree with the DID (Dissociative Identity Disorder) theory where he has double personality. What I want if he is the Big Mouse then it's because it's indeed Him not the other him.

Ana Aug 11 2022 12:21 am I think the real big mouse is the one who has tattoo on his wrist..just pretending that chang ho is his idol so that no one knows he's the real Big Mouse and the mayor is his accomplice.

dara Aug 10 2022 5:44 pm Replying to crypticGal

Gal, I went back to those scenes. The names on the Mayor’s list are not shown, just Moho’s list. Anyways, I’m suspecting Miho, her father, or the best friend BUT big mouth seems to be in the prison too (if he is, the young angry-looking guard or Jerry). As you can see, my suspect list is overflowing - this is exactly what the drama wants me to do. Suspect Everyone!!! So, I’m just going to keep my mind open and enjoy the drama haha

Memi Aug 10 2022 5:37 pm @Jenni,

I feel your enthusiasm! How could one not when watching this drama? It is really good and presented like a great piece of puzzle, with different possibilities to the story no matter which theory you choose. And no, you shouldn't wait till the drama is over to watch. You will lose out from all the fun because the storyline will be discussed every week and you'll only get spoilers. Keep guessing, go on.

I come up with a different big mouse every time I watch. Today I went back to ep 1 & 2 again and guess what, I try to watch it to find out the possibility that Park Chang Ho is the one and yes it fits! And I took a careful look at ep 1. Early on in the intro there's a man in the rain coat, the one dumping the gold, guess what? It is Lee Jong Suk! haha... if I can't recognise him I would have to disqualify myself as a fan! So now my theory is it's a Robin Hood/hero concept. He is Big Mouse and makes himself go into prison to capture the real leader of the corrupt group (the elder?) because he is aware that the prison is in cahoot with the group. He is the mouse after Tom.

Another theory a few days earlier: Fortune teller. He has the motive. He lost his daughter (could have found out that she came to harm under the corrupt group). Somehow landed in jail even though that should not be his sentence... and now is trying to exact revenge through Park. But a little problem... he wouldn't be able to manipulate and get Park into jail to fulfill this plan. So who knows?

I'm glad everyone is having fun guessing.

Toloee Aug 10 2022 2:51 pm It's definitely Chang ho he probably just has multi personality disorder and can be whoever whenever Till then sha let's all fold our arms But this show really is worth every minute of my time !! I love the anticipation and how we viewers have so much discuss

Egleeye Aug 10 2022 2:04 pm I thought Big Mouse was Chang Ho, he forgot some important things because of the accident. He even forgot that his punch was very strong.

Bigmouse Aug 10 2022 9:39 am Gorgeously executed and funny, but i think the mayor is the big mouse

Quincy Aug 10 2022 9:37 am This is really interesting, i think jerry is the big mouse

jenni Aug 10 2022 2:12 am Replying To Memi

hii, i get where ur coming from and i 100% agree with u that a lot of people are definitely gonna switch up and will started trashtalking the show. But i‘m not like that. No matter which ending we will become i will be satisfied. I just like having some theories because you never know if it might be true or not. I actually wanted to wait until the kdrama is over but I‘m glad I started so that I have this „impatient/excited“ feeling that makes me feel like dying because I just wanna know what happens next… :)

CrypticGal Aug 10 2022 12:27 am It's Miho or Miho's "father" or the Bestfriend. Go back to ep. 4 look at the names Mayor Choi Doha got from the list and the ones given by Miho to Chang Ho. They're not the same bruhhhh. I've just now realized it after watching those scenes again.

Lady L Aug 10 2022 12:16 am One of the greatest show of this year so far. The creators of this show make us all unite to find the mystery of who is Big Mouse. It feels like we are helping the male main character, Park Changho to solve this mystery. With the amount of zillions theories out there, I just hope whoever the big mouse is, the writers will give us a believable and reliable reasons to the story.

Also, there's one thing that become mystery to me is why no one so far besides Changho's trying to wonder or find out who is the Big Mouse? No one asking, Where is Big Mouse? Why they only focus on a question like "is Changho the Big Mouse"? even the closest people to changho didn't even try to find the real big mouse? or are we going there someday? Still a mystery to me.

Anyway, it's a great show. Keep up the great works everyone!! ??

Ahnah Aug 09 2022 11:15 pm Instead of thinking much and naming almost all the characters as Big Mouse, let's just patiently wait for the incoming episodes surely Big Mouse will be revealed by then.

Memi Aug 09 2022 7:44 pm It’s great to guess who is big mouse and the plot, but some here (esp one with multiple accounts) really go a little too far and guess without any logic TT (actually, don’t mind me, my guess keeps changing too).

I hope it won’t turn out like W where everyone has their own theory and when things were not what they guessed, they began to trash the show.

tim ong Aug 09 2022 7:36 pm If Chang Ho isn't Big Mouse then I feel like this can go into “Breaking Bad” direction where he ends up “becoming" Big Mouse out of pure necessity and then has a hard time letting go of the character afterwards.

jenni Aug 09 2022 4:51 pm Okay Plotwist!!!

Big Mouse Is The Name Of The Group!

Miho, his father in law,kim soon tae and Chang Ho are the members of big mouse but the head of all of them is Miho… That‘s why Chang Ho keeps saying he isnt big mouse, because its a group and he‘s not the „leader“. Maybe thats why they are „framing“ him as big mouse and he doesnt know that it is his wife,his father in law and kim soon tae. They wont tell him for a while so that it looks more „natural“ also they framed him to not get him killed in prison [indjuri‘s theory] this serie will definetly have a big plotwist like mouse [kdrama]

indjuri Aug 09 2022 1:28 pm SPOILER!!

I kept thinking Miho is Big Mouse. Here's what I thought. Chang HO was framed for using narcotics by Jihoon and will be killed. Miho had predicted that so she framed Chang Ho as the Big Mouse to save his life and buy some time (because if everyone thought Chang Ho was Big Mouse, no one would kill him), meanwhile Miho was trying to get Chang Ho out of prison. 5 names on the list from Doha were entrusted to Miho, if Miho was Big Mouse, she could easily give the actual list. Besides, Miho is smart and thorough (for example before injecting medicine into a patient, she took a photo of the prescription first). She is capable to be it.

This drama is so good, can't wait to see next episode

yuri Aug 09 2022 10:56 am why do i think the guard gan soo chul is the big mouse lololol

Meerah Aug 09 2022 5:41 am This is really nice. I'm super hyped about who the big mouse is♥️

Kim Aug 08 2022 10:57 pm The series is so interesting, waiting for episode 5 ??❤️

Gimbiya Aug 08 2022 4:43 pm List of sis - Jerry(big mouse) Miho's Dad(big mouse or elder) lawyer always with Minho(big mouse because he also works in the office) the old grandpa I'm prison (Intel for big mouse) and finally Park Chang (Big mouse).

Happy Aug 08 2022 2:29 pm Who is the third person that was supposed to have his wish granted?! 'Cause Jerry said three people but then only the psychopath and the room leader were shown! I don't know I feel the third person is important? And the room leader's missing daughter? I suspect it's Miho annnndddddd the Father in Law, the Father-in-law is susss. Wait what if he's the elder( the Father-in-law I mean)? Wow! This drama is gooodd

Myfavorite Aug 08 2022 5:35 am Great drama so far, interesting i was thinking the room leader daughter’s missing maybe (Miho)?

Nia K. Haryanto Aug 07 2022 11:31 pm Another great drama from MBC. The first 4 episodes are very interesting. The plot is interesting. Hopefully the next story will continue to be interesting. Really hope the ending is happy, and not like The Mouse drama. :(

honeybubu Aug 07 2022 12:24 pm I think Jerry is the big mouse.. jerry like in tom and jerry lol AND he also said he was a scammer/swindler?

James Aug 07 2022 11:06 am I guess Jerry or no park is the big mouse

Sneha Aug 07 2022 10:06 am Jerry is undoubtedly sus but I have a feeling that our main hero I mean big mouth is big mouse he turned himself in he was the one who gave anonymous tip about himself cause he’s been trying to take all the dirt out of that jail system that A category B category and the C’s it’s all dirt our big mouth have a big reason to do that according to me !! He was quite for 3 years since he married our heroine but then that hospital case he knew that he need to do a comeback!! Well it’s just a theory but let’s see …

fayi jjj Aug 07 2022 8:33 am i think Jerry is big mouse

Shai Aug 07 2022 8:17 am I have a feeling that Jerry is Big Mouse!

who's the real big mouse? Aug 07 2022 7:55 am why no one talking about the mayor?? choi doha. he is the first person that started all of this things. he called park changho to join him agains the VIP, just because changho is not that good as a lawyer so he choose him. he probably know that his wife(?) know about dr. seo document that makes him die. he didn't have a good relation with gong jihoon. he stalked go miho (helped by his secretary). even if he helped changho for the list of the BM buyer, i still can't trust him lol. i can't trust anyone:) i hope it's just my assumption.

anyway, i can't wait for the next episode.

Isife saiki Aug 07 2022 6:04 am Theres something between the guard, jerry, no park and to prosecutor.. i dont know i just can feel it hehhe

N3g Aug 07 2022 5:57 am I think who always help park chango Is guard gan soo chul and jerry. This 2 really something connection with real big mouse is park chango.. he just pretending.. like the mouse ..

Owwww love so much plot twist later...

Bm Aug 07 2022 5:02 am The next ep is really excited, I can’t wait for the next Friday, every episode better and better.

Betty Aug 07 2022 4:51 am I love LJS and Yoona acting . On ep 3 they encountered in jail visit made me cry. They have such awesome chemistry , Lee Jong Suk already an A lister but Yoona proves she is great actor too. Can’t wait to see the rest. The story is great nothing boring so far so good .

Leah Aug 07 2022 12:46 am I really think Jerry is the big mouse.

Kimchi Aug 06 2022 9:25 pm every one is pointing out at Jerry but it really makes sense since from the start I'm not even sure what crime he committed.

But! I'll be really disappointed if Jerry Is the real big mouse because it already reflected from the start.

I hope that Big Mouse is something we can't imagine!

Big Mouth is pronounce Big Mouse Aug 06 2022 8:15 pm This show is making the audience playing detective to find out who the real Big Mouse is. I love it. The actors are perfect. Lee Jongsuk is such a great actor. The directing style is cool. The plot and setting are acceptable. The build-up storyline, the noir and comedy works well together. The show is just getting better every episodes. It is worth to binge-watch.

Spoilers alert! Here is my theory to the potential list of who could be the real Big Mouse with his potential helper :

- Miho's Father & The Lawyer Best Friend. In Ep.1, Big Mouse crime's evidences were all found in their office. They entered the list as the first SUS.

- The Prosecutor. He knows so much. He double-cross Gong Jihoon and The Mayor. If he is not the big mouse, he could be one of the big mouse's trusted man outside the prison. As according to ep.4, the big mouse is inside the prison. Then the SUS goes to... ⤵

- Jerry "The Big Mouse Fan". He is way too good to be trusted and too clean to be in prison. We also still don't know who his real name is. Even the Cell Leader, Mr. Noh Park is also potential to be The Big Mouse. Maybe they work together to frame Changho as soon as he arrived in prison.

- The Prison Guard. This guy is everywhere around Changho since the first episode. He knows and sees everything of whatever happen in the prison. He can be anywhere do whatever only god's know where there's no cctv watching.

- Lastly, Changho himself. Well, nothing is impossible. What if he's lying to all of us since the very beginning? At first, he needs to act like he hates himself being called as big mouse because he is being watched by CCTV that directly controlled by the warden, so he's got to lie to us all the time. What if Big Mouse is actually doing good things in a wrong way ala Robin-Hood rob the rich for the poor? So, he put himself in prison to do justice. idk.

This show has brain. Every single characters are potential to be the Big Mouse. Worth to watch.

nazareiym Aug 06 2022 7:14 pm i think big mouth is jerry ^_^

Zori Aug 06 2022 6:29 pm I guess Jerry is the real BM.. In ep 4 when the room is being searched on Jerrys hand is a tattoo of a mouse lol

What a come back Aug 06 2022 5:09 pm Just out a little while ago and it's up:

Nation-wide Nielson rating 8.6%. Many are hoping it'll past 10% next week.

What a come back Aug 06 2022 4:58 pm Congrats to Lee Jong Suk! This is a fabulous comeback. Big Mouth is really fascinating!

Listed as a noir drama, with a prison setting as background it is definitely not everybody's cup of tea especially for the huge group of drama watching housewives. Was thinking if this will not attract viewers. Luckily it is doing well and rating is going up. Korean chatrooms are filled with chatters... everyone is wondering who Big Mouse is and are praising everyone's acting. And almost all characters in the drama with 3 lines and above have become a suspect lol yes it's that crazy. 10hours after broadcasting (ep4) the comments are still coming in every minute.

Big Mouth is interesting, suspenseful and hilarious at times. It is very immersing and I am able to concentrate on the show unlike many Korean dramas nowadays. Ep 1 was probably just okay but stay on your seat - it took flight from then on and keeps getting better. There are antis launching a campaign against the show because of the fan fighting between female lead Yoona's fans and another idol's fans. Ignore those comments about the show and check it out yourself BEFORE THE ANSWER TO WHO IS BIG MOUSE COMES OUT.

My guess to the big question? I think (possible spoiler ahead) it's probably the mayor's wife working with Jerry and the prosecutor lawyer. Maybe Jerry was sent by her to be a mole in the prison. ATM I think she is the one. Or it could be just Jerry, or the prosecutor, or....

Fans Aug 06 2022 4:45 pm It’s still a puzzle to me, all is suspected, being a BM.

Darkeyes28 Aug 06 2022 3:40 pm Who is the Big Mouse? I am confused.

Kdrama addict Aug 06 2022 1:49 pm I think jerry is big mouse

Justyou Aug 06 2022 12:32 pm Main Lead might be big mouse. Or have personality disorder? We still dont know anything about main lead’s background and who his family are. It seems that he really loves money and want to be rich so big mouse might be his second personality if that was the case but that’s just my theory.

Ucitt. Tiger Aug 06 2022 12:31 pm I think Jerry/kim soon tae is the real big mouse

Lovee Aug 06 2022 12:18 pm My theory is, there is Two big mouse. The good one and the bad one. If there is two big mouse then im thinking park chang ho is the other good big mouse where he’s in charge of the client list but he doesn’t distribute any drugs or do any illegal activities. Because park chang ho do used money recklessly too….Or Jerry is the real Big Mouse since he said big mouse is his idol…anyways the drama is starting to get good. Cant wait til they reveal who big mouse is!!

BM Aug 06 2022 12:08 pm The fortune teller/room leader maybe the real Big mouse…

Street fighter Aug 06 2022 10:58 am after watching preview of ep 5 I think ML park Chang Ho is real Big Mouse or is we saw in ep 1 staring Big mouse is just dumping gold in random construction site so Law farm build may just random site where Big Mouse Hide gold and durges but now Chang Ho become Big Mouse and real one might be dead now.

Nas Aug 06 2022 10:53 am I think Jerry is the big mouse... 100%....

jerrythebigmousefan Aug 06 2022 10:40 am after episode 4, i think there's 2 candidates of big mouse now. chang-ho himself (doubtful, but writernim can make it through with DID plot or other plot) or jerry a.k.a kwak dong yeon's character. mi-ho's father = big mouse is now a weak guess, the inmate deaths countered it. can't wait for more next week!!

kdrama fan Aug 06 2022 9:29 am Big Mouth or Big Mouse??? Lol

So many are confused!

jcl Aug 06 2022 9:28 am I remember Johnny Depp's movie. the tourist in this. I think he is really the real big mouse!

I have one more theory though. Jerry one of the inmate can be big mouse as well.

jcl Aug 06 2022 9:21 am Jerry one of the inmates with mouse tattoo is the Big Mouse!

Twitter Introduced Big Mouse to me Aug 06 2022 6:33 am Theory*** I wanna share my theory. I think, the big mouse could be Miho’s dad. Maybe he is not her real father and only used them to cover his real identity. As he knows, changho is kinda not a ‘smarty’ one. If you guys watch early eps, he said that he was once a police/head/inspector? Maybe there is plot twist such as Miho real father is actually the leader of Changho cell who ask him to find his daughter that went missing..

Everyone looks suspicious to me. But I want happy ending for the leads please writernim. They are each other happy/comfort place. Kudos to all the actors n staffs of Big Mouse. I’m hooked and cant wait for next episodes.

Introvert Aug 06 2022 4:37 am Lee jong suk is awesome!!. Superb actor!

BM Aug 06 2022 3:07 am When MH visited her husband it’s really break my heart, it’s good that her wife is strong woman…

sf Aug 06 2022 1:42 am I don't feel anything watching this drama. It has no suspense, the actions are predictable, and the male lead is from another picture. He cannot show us a taff guy look. I couldn't see in him the change from Chang-Ho to Big mouse. His acting and facial look are the same. This type of role is not for him. On the other hand, the female lead does pretty well with her character.

Jlo Aug 05 2022 11:40 pm Jerry (Kwak Dong Hyeon) is the Big Mouse

Valesong Aug 05 2022 11:34 pm Big mouth is her father

z Aug 05 2022 9:10 pm now i'm suspecting gong ji hoon as the big mouse in collaboration with hyun joo hee:/

swooning-over-how-amazing-this-drama-is Aug 05 2022 3:24 pm Wonderfully amazing , it's been a while since I've watched such great piece of art. It's really a very powerful great drama. I hope they won't screw it up.

Brain Aug 05 2022 2:53 pm This drama is so great, and somehow funny

Tokyo siram Aug 05 2022 12:23 pm Already 2 episodes and all going strong. Please don’t make LJS a fragile character but a strong one for sure. I just loved when he threw punch without knowing its impact. Can’t wait for full episodes.

Street fighter Aug 05 2022 12:02 pm Just 3 Episode but It's like end, How he warn warden and his action are like real big mouse I want he hit solid punch on warden face.

Also Yang Kyung-Won acting I really like it, I always remember his acting in crash landing on you, his acting so good to when I see him in this drama I forget his character of Crash landing on you and Vincenzo.

sandbox Aug 05 2022 4:00 am reunion of chul san and yong san haha

Leeriaa Aug 04 2022 8:57 pm It sounds strange but 5 of 6 main characters in this drama have letter H to begin with in their names, and maybe Jerry too(i dont know his real identity till now so…) Maybe it is just coincidence or it is a big clue for us to find real Big Mouse swindler?!!

San Magh Asi Aug 04 2022 1:44 am I wish to see kdrama related about engineer in near future

Dont_Touch_My_Wife Aug 03 2022 8:53 pm Great drama :) Cant wait to see this week ep , especially i see preview ep 3 Park changho give a warning whoever wanna touch his WIFE .....

Bebe Aug 03 2022 7:20 am Great acting from the leads. and great drama so far

Lucy Aug 02 2022 8:23 pm Lee Jong Suk plays as Park Changho in noir or crime genre drama will always be a bless to watch. His acting skills is tremendously amazing. This type of drama will expect us to get a big plot twist, but yeah, i think the plot twist we will get is that the real big mouse is the father in-law. I mean who the hell have access to put those money, gold, drugs,etc at their office while Park Changho didn't know anything at all. Once he knew who the big mouse is, he will take the legacy as the next big mouse. I think. Well, it's like Dr. Hank Pym's situations when Scott Lang take the title Ant-Man. It's gonna be fun to watch anyway.

Gimbiya Aug 02 2022 4:30 pm Oh Gawd somewhere deep in my head I think he's the real bug mouse! I don't want to believe he's Innocent he's character is too wimpy. But at the surface of my head I an sure his father in-law is big mouse to cap! That man is always appearing evill in dramas why not this time

Lyn Aug 02 2022 8:36 am Love it so far, I’m really curious who is real big mouse, i have in my mind but it’s to soon it’s only 2 episode, the cast are all good…

GoMiho Aug 02 2022 5:40 am Omg this drama was so amazing the cast, acting, visual,plot, chemistry everything is perfect. Lets hit big Big Mouth❤❤

Olive Aug 02 2022 3:25 am Happy to see my husband lee jong suk in new drama!!

I'm always fond of thriller, revenge drama and a lot of them has similar plot but this one is freaking different. I have my guessed already who's the big mouse by watching 2 episodes and I hope i will still shook if that person I choose is not the big mouse lmao.

Anyway! Please support them with yoona. Yoonas character here is almost the same in "exit" a very supportive, caring loving lady and he's dad I love it!! That actor is really good when choosing a drama to jive

Oppo Aug 01 2022 5:57 am I am sensing a combination of the US American series Prison Break and The Tourist movie in this drama. Very interesting story so far...

dala Jul 31 2022 8:53 pm what if jerry is the big mouse or at least his/her accomplice?

dulKhab Jul 31 2022 5:10 pm I'm agree, the quite sound in the some scenes would be perfect.. than ruin the moments

Sun Jul 31 2022 3:23 pm They put way too much background music!

Yellow Jul 31 2022 11:53 am he tried to kill himself but ended up being the most feared person in prison LOL

Matts of LJS Jul 31 2022 6:38 am Omoooo!!! I waited so much for LJS drama. This Big Mouth is so much fun to watch anc will definitely watch all LJS projects. ? Lablab

Anonymous Jul 31 2022 3:54 am A fun drama!!! The best. Can't wait for the next ep. Jongsuk and Yoona's acting & chemistry is insane!

vianey Jul 30 2022 11:32 pm @A NO. Technically, it is correct. There is really no way to spell "th" in Korean. Just like they switch F for "ㅍ" (p)

NN Jul 30 2022 9:50 pm What if PCH is the real Big Mouse? What if he is the anonymous informant who arrange everything to put himself behind the bars? What if this is all part of his masterplan?

Interesting to watch...

fan Jul 30 2022 2:10 pm If it ends up like Mouse, imma cry bcs of the plot twist ?

Ren Jul 30 2022 2:07 pm After watching the first and second episode... Well, he is asking for it lol But he don't really deserve that kind of punishment
