Synopsis

After failing to get into university and becoming a hikikomori, Kurosu Etsuro attempts to commit suicide, creating a hole in his wall in the process and allowing him to peep in on his neighbor, Miyaichi Rio. Although fascinated by Miyaichi, Kurosu ultimately witnesses her brutally murder a man and gives himself away after screaming. In an unlikely turn of events, the two begin dating after Kurosu confesses his feelings–but will he end up as another one of Miyaichi’s victims?
