Part One Sanjua is a high school student and a famous private detective. There has never been a case he investigated in which the criminal was not caught. One day, he received a case about the kidnapping of five female students living in a shared dormitory. During the investigation, two of the girls were found dead in an old storage room in the same building. The bodies were decapitated, and signs of torture were found. The case was handed over to the police. While Sanjua was investigating, questioning some people, and reviewing the surveillance camera recordings, they noticed a strange person wearing a mask and watching the victims' dormitory in a suspicious way. After more investigation and questioning the residents, they discovered that the person lived in the neighboring building and was a writer of crime novels. My Writing ✨
