"I'm experiencing the harem life in a prestigious all-girls' school's dormitory?!" Haruto has been caught in a conflicting situation. His acquaintance had recommended him a job which also involved him living there at the same time, and he decided to apply for it, without actually telling Haruto that the job was being the manager of a prestigious all-girls' school's dormitory. While doing his best to not screw up, he ends up becoming closer with three particular girls. Natsumi Rin, who acts quite cynical when around Haruto. Akishima Hiyori, a cat-like girl who enjoys teasing and pranking Haruto. And Fuyusaki Aiko, a girl who always seems to have a yearning gaze while looking at Haruto. Then all of a sudden, he gets into a sexual relationship with all three of them. The story of the three girls who live in the girls' dormitory starts rolling in an unexpected direction.
