Fate seems relentless for Dong-ju as he encounters a car accident and learns of his mother's DUI offense, further adding to his hardships. Like many others who reach rock bottom in real life, Dong-ju makes an unwise decision when he accidentally comes across the script of a novel belonging to the victim of his car accident. To his surprise, the novel achieves great success. However, the situation takes a turn when the boy Dong-ju hit finally regains consciousness.

Dong-ju's primary concern upon the boy regaining consciousness is whether his old memories have returned. Dong-ju is fully aware of his grave mistake and feels obligated to reveal the truth, regardless of whether he remembers anything or not. Simultaneously, as the murder cases and missing persons investigations progress, the similarities between them intensify, leading to a growing momentum. However, Dong-ju has no idea how this would affect him.

Hyun-soo suggests putting up a banner to look for Kang-san’s family. Kang-san gets discharged from the hospital and decides to stay at Dong-ju’s place. While inspecting the site of the accident, Kang-san sees a boy and follows him. Kang-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.
