I am a detective, a detective who never ignores any details, but this case was completely difficult for me. The victim was a student, but the killer was the same age as him. Without leaving traces and clues, I can't imagine that a minor could design such a perfect case. In order to get more information, I went to the victim's school to investigate and got a lot of information. In the process, the suspect gradually emerged, and the victim seemed to have many stories in this school. However, I always wonder about one question, who is the devil behind all this? Is it an individual, the deep-seated human nature, or is it a problematic system? Was my direction always wrong?
