Episode 8 recap: Hua Zhen submitted his resignation letter.

Chen Hao was searching for clues in the archives, but was accidentally locked in overnight by a patrol officer. In the early morning, he managed to escape when the cleaning staff came. He coincidentally ran into Captain Feng, who had been obstructing his investigation and had looked down on him. Hua Zhen felt the case was complex and was worried about implicating his colleagues, so he decided to resign in order to investigate further. He gave his resignation letter to Chen Hao, who had seen a missing person notice in the newspaper and thought he had found a lead, but then learned that Hua Zhen was leaving his job.

Hua Zhen explained his decision, and although Chen Hao wanted to persuade him to stay, Hua Zhen's mind was made up. Outside, Luo Min Min misunderstood Hua Zhen's words. As Hua Zhen was leaving the police station, he coincidentally ran into Luo Min Min's family, who invited him to dinner. At the same time, his classmate Hua Liang also found him and expressed curiosity about why Hua Zhen was working at the small police station. Hua Zhen promised to give him an answer in two weeks.
