There he met his high school classmate Fu Hailin and a group of people with very different personalities. After several chats, he was even more devastated. He just wanted to get drunk and wander around the streets, and was knocked to death by the bosozoku. At this time, he met an underage girl Gu Qiaoze and her beautiful aunt Gu Yinxue. The next day the newspaper also published news about a perverted serial killer with extremely cruel methods. Unknowingly, Gu Song seems to have become the next target of the perverted killer.
