Hyun-soo suggests putting up a banner to look for San's family. San gets discharged from the hospital and decides to stay at Dong-ju's place. While inspecting the site of the accident, San sees a boy and follows him. San finds out that the boy has been abused by his mother. Meanwhile, Hyun-soo visits Dong-ju at his place and asks what motivated him to write the novel.

Hyun-soo tells Dong-ju that the murders in his novel are happening in real life. Dong-ju thinks Hyun-soo's claim is outrageous, but he finds out that she is right. But Dong-ju doesn't report it to the police because he's afraid of losing the luxury he's enjoying. Meanwhile, Byung-man visits Assemblyman Byun and asks about the murder case from 27 years ago.

Dong-ju visits his old high school's principal and sees a photo of a man who looks exactly like Ki-jeok. He asks around and finds out that the man in the photo is Lee Kang-san who went missing in 1995 with his brother, Lee Ha-neul. Meanwhile, Ki-jeok tells Dong-ju that his memories are coming back and that he remembers meeting Dong-ju's father.
