In Believer 2, Rak manages to find Mr. Lee, the elusive criminal Jo Won-ho and Rak have been trying to find for years. Tzi Ma plays Lee Yang-gwak.
Mr. Lee is a notorious criminal who runs the largest drug organization in Asia. He is a mysterious man whose name is known by everyone, but no one knows who he is or what he looks like.
The police have been looking for him for a long time. Even after searching for him for two years, Jo Won-ho fails to find him. It is not easy to catch Mr. Lee when several drug lords who wish to acquire his reputation, such as Brian, falsely claim to be Mr. Lee.
Jo Won-ho’s search leads him to Rak, who works with him to find Mr. Lee. Jo Won-ho eventually starts believing that Rak is Mr. Lee, but he is proven wrong in Believer 2.
Mr. Lee’s link with Rak’s past
Twenty-five years ago, Rak’s parents grew opium poppy for Mr. Lee, who was a science teacher. They trusted Mr. Lee, but in the end, he betrayed them. He got them on a smuggler boat and drugged their food and water.
Rak’s parents died, but he survived. He has been looking for Mr. Lee because he seeks revenge for their deaths. Rak believes that he will be able to get rid of the smell of his parents’ corpse that has followed him for years if he kills Mr. Lee.
Rak knows that if he assumes Mr. Lee’s identity and creates trouble, his most trusted subordinate, Seob So-cheon, will hunt him down. Rak wants So-cheon to find him because he believes that she will lead him to Mr. Lee.
When Rak steals raw materials from Brian’s factories and leaves a sample of his drug in Bo-ryeong’s hand, So-cheon finds Rak and makes him produce Laika for Mr. Lee. However, Rak comes to know that the drug lord has retired and will not be coming to meet him.
Mr. Lee’s death
Mr. Lee contacts So-cheon, and Rak uses her phone to track him down. As Brian has kidnapped Rak’s friends, he needs to kill Mr. Lee not just to exact revenge but also to save his friends.
Mr. Lee is living in Norway. He has retired because he wants to live the rest of his life with his family. When Rak finds him, Mr. Lee tells him that it was his academic curiosity that led to him inventing Laika.
However, he kept producing and selling it because he wanted to test the limits of human pleasure; he wanted to trade in happiness. That was in the past. Now Mr. Lee has become too ordinary, and he regrets that.
Mr. Lee feels no remorse for killing Rak’s family. He is not even moved by the news of his own family’s deaths. In fact, he wants to start a new family with Rak, the man who killed his daughter and granddaughter.
Rak realizes that Mr. Lee does not know what it means to be family, so he refuses his offer. When Mr. Lee tries to kill him, Rak shoots him dead. Rak avenges his parents’ murder, but he does not find peace.
