Putting the pieces of a puzzle together, Ga Hyeon finds out who the real culprit is and successfully confirms his identity. When Hyeong Ju hears her speculation, he refuses to accept that the real culprit is Sun Ho and storms out of his hideout. Hyeong Ju then retraces his memories and does an additional investigation to confirm Ga Hyeon's reasoning. Meanwhile, Sun Ho unexpectedly shows up at Ga Hyeon's house.

Hyeong Ju and Ga Hyeon find out that Sun Ho is the real culprit who is responsible for the deaths of resetters. In fact, they also realize that Ga Hyeon's house is wiretapped by Sun Ho. Hyeong Ju understands that this is an opportunity to reveal the true identity of Sun Ho, and he sets up a trap to lure him.

Luring Sun Ho into Hyeong Ju's trap was easy, and the police arrest him right after he fires a gun at Hyeong Ju. It seemed as if everything was over, but Hyeong Ju discovers that Hwang No Sub has been lying and hiding his identity all this time. When he and Ga Hyeon visit him, people there greet them as if they expected the visit.
