The story follows The lawyer Park Chang Ho (Lee Jung Suk ), known among his friends by the: Big Mouth. He is actually a very ordinary lawyer, he don't win many cases, he has a lot of debts and he lives a happy life with his wife Ko Miho (Yoona) and his father-in-law. One day, he receives a call from an important person asking him to take over the defense of a three people accused of killing a professor working in Kochon Hospital, who will later appear to be a great danger to this elite. Chang Ho agrees in exchange for fame and money ofc , but he have a car accident and gets up to find out that he is accused of being the notorious criminal and looter money : the Big Mouse. He is arrested and the events goes on, Chang Ho transferred to the prison where he will resist to survive in this dark world that controled by the The corrupt elite that got him involved in these events from the beginning. We continue to try to guess who is really the big mouse, and what if he is it Chang himself. Suspicion will reach us the point that we can suspect his wife and even his father-in-law! At least that what happened to me!
A very wonderful weave with many puzzles and surprises in each episode, and the mesytrious events never loses its level, it continues to increase it in enthusiasm and suspense.
All the characters are great, and I loved the strength of the female cast, especially Ko Miho.
Unfortunately I feel disappointed in the end because of these points:
1- Ko Miho didn't have to die to order to destroy the evil elite! And Chang Ho to really become big mouse. It broke my heart, their perfect couple didn't deserve this end.
2- they mentioned that serial killer son of the old man but he didn't appear which confused me cuz he seemed important to the polt. And i was thinking if there's a season 2 to avoid this gap?
3- and i hate that no knew that Hee Jin was killed by her psychopath husband and no one seemed to be concerned about her.
But at the end i gave it 10 cuz it's a very good drama, and i loved every detail about it from the acting, the polt, and the chemistry between the main leads, they are amazing. And I'm very proud to watch Jung Suk coming back with such a good drama.
