Fog Pupil

Sang Luo, who suffers from borderline personality disorder, is naturally sensitive and suspicious, but also focused and persistent. He spent two years getting close to a girl named Shu Pei and established an online relationship with her. Just when the two were preparing to meet offline, Shu Pei's friend Zhang Liu was hanged alive in the demolished building. The strange thing is that Zhang Liu deliberately invited Shu Pei to the scene before his death and was wearing a red dress when he was killed. Shu Pei became the first witness at the murder scene, and the ghost hand pattern under Zhang Liu's body was also closely related to Sang Luo. Since then, Shu Pei and Sang Luo were forced to get involved in this strange murder case, and they also became acquainted with policewoman Han Qingdai. Sang Luo, who became a suspect, had to use his hated congenital mental defect to investigate the case. The murderer did not stop, but left a warning of the crime, which was bound to kill all Shu Pei's friends. Sang Luo also discovered during the investigation that the murderer should be a born psychopath like himself.
