After the investigation at the police station, Ga Hyeon helps Hyeong Ju track down Bae Jung Tae, who might hold the key to recent mysterious deaths of fellow resetters. Although they are yet to locate Bae Jung Tae's whereabouts, Ga Hyeon finds something weird about Lee Shin's phone number at Bae Jung Tae's place.

Ga Hyeon and Hyeong Ju eventually get in touch with Jung Tae and in doing so, they find out his relationship with Jeung Seok. However, as more they look into the mysterious deaths of the resetters, the clues somehow direct them toward Lee Shin. Ga Hyeon, in the end, decides to visit Lee Shin just to find out she has left the country.

Ga Hyeon and Hyeong Ju are certain that Jung Tae is the bad guy and Jeung Seok is just one of his many victims. However, this all flips around when they come across a conversation between Jung Tae and Jeung Seok. In the meantime, Jeung Seok is found dead and Lee Shin calls all the remaining resetters for a meeting.
