As the worst delinquent of his grade, Kikuma Teranishi is forced to change dorm rooms after breaking the school rules one too many times. Reluctantly entering his new room, he comes face to face with the dorm superintendent, Takasumi Uryuu, who stirs in him hitherto unknown feelings... Kikuma's body tingles, and he wants to take out his urges on Takasumi... What is going on? The next time Kikuma breaks the school rules, Takasumi lays down a ground rule that sparks their relationship: "If you obey, I'll reward you. If you don't, you get punished." (Source: Renta!)
