The male protagonist Zeng Dawei, who dropped out of high school due to mental illness, became deeply obsessed with everything about criminal police while he was locked up. From then on, he began to learn about criminal police on his own. With the help of his attending doctor, the attending doctor's lover, and his good friends' family, he gradually came into contact with and solved a series of difficult cases. But later, he accidentally came into contact with the shocking case that befell his wife, his attending physician, more than 10 years ago, and he began to investigate in depth. During the process, his best friend passed away, and one case after another occurred frequently at his parents' workplace, and his parents were involved in this case. Later, he finally walked out of the room to overcome his heart, only to find that the truth of all this was horrifying. Like falling into an ice cave.
Fortunately, in the blink of an eye, he was still a high school student, still locked in his room, but his case just appeared like a dream. The only thing that remained unchanged was that he once again took on the role of campus detective in school. Until he chose the future and later left school, Zeng Dawei still shouldered the mission of safeguarding justice and acted as a messenger between black and white.
