He Wei, captain of the Criminal Investigation Detachment of Jiangyuan City, Donglin Province, Yan Ning, professor of the History Department of Donglin University, and a specially appointed portrait expert of the Jiangyuan City Public Security Bureau.
The two had already known each other in the late summer of 2003. At that time, He Wei's father, He hope, was still the captain of the criminal investigation detachment. He died accidentally while handling a serial murder case. He Wei was picked up by his father's colleague, where he met Yan Ning, who was also staying here.
The summer of 2004 was the beginning of the formal exchange between the two. Yan Ning, who was already in college, often took He Wei to hang out in school to help him resolve his worries. In this way, after a long summer vacation, the two naturally got together.
Fourteen and five years later, in 2017, when the murder case of He hope gradually became clearer, He Wei also officially ushered in the opportunity to "meet his parents-in-law." Yan Ning's parents and he finally had a suitable opportunity to start the meeting that had lasted more than ten years.
The emotional line is mainly about the life of two people as an old married couple, with occasional quarrels and occasional jealousies.
The story line mainly consists of about eleven cases, and the truth of He hope's death will also be revealed at the end.
Intention: Everyone has their own greatest evil in their heart. Some people choose redemption, while others take the evil path.
