As suggested by Lee Shin, Se Rin tries to flee from Seoul with Young Woong. However, Young Woong leaves Se Rin at the bus terminal to meet Hyeong Ju to file a suit against her. Meanwhile, Jung Tae, who was also one of the victims of Se Rin's lies, gets parole and visits his sister who recently underwent heart transplant surgery. As the resetters start to lose trust in Se Rin, she desperately asks for help, saying that she will be the next victim.

Ga Hyeon struggles to decide whether to help Se Rin or to ignore her for her deceitful wrong doings. Even before she had time to make a decision, Se Rin is found dead. Hyeong Ju and Ga Hyeon sort out Young Woong and Jung Tae as key suspects, but it turns out that their alibis are legitimate. Meanwhile, Jung Tae makes another deal with Lee Shin.

It was no surprise when Hyeong Ju finds out Jae Young was with Se Rin hours before she was murdered. Meanwhile, Jung Tae is threatened by Jae Young's father, a nominee for the Minister of Education, to stay low until the hearing is over. While Ga Hyeon being confused by a series of puzzling events, Jung Tae faces a death threat by an unexpected acquaintance.
