Synopsis: Doukyuusei Seikatsu

Former middle school classmates, Mizuno and Mitazono had personalities that were entirely opposite. After some years, Mitazono contacts Mizuno asking for help with a group of abandoned kittens. Despite his reservations, Mizuno agrees to help and temporarily moves into Mitazono's home to take care of the kittens. Consequently, they unintentionally end up living together as ex-schoolmates.
