Fang Tu entered the orphanage when he was young and had doubts about his identity since he was a child. Before joining the police station to investigate undercover, he was accidentally rescued by Zhu Zhiran due to an asthma attack, and the two got to know each other.
The two jointly investigated Zhao Feng's wife-murder case and discovered clues about the core figure in the abduction and trafficking incident at the welfare home where Fang Tu was located. They followed the clues along the way to find out the truth about the murder of Fang Tu's biological father and Zhu Zhiran's mother. During this period, Fang Tu was injured while protecting Zhu Zhiran, and the two went from being ambiguous to confirming their relationship.
In order to arrest the leader of child trafficking, Fang Tu was ordered to serve as an undercover agent and enter the trafficking group. On the surface, his temperament changed drastically, but in fact, he cooperated with Zhu Zhiran inside and outside and solved the two major trafficking groups.
