Kiumi is a college student who's famous for being open about his orientation and an active top. Shizume, who's in the closet and the same class as Kiumi, doesn't like how open Kiumi is about his adventures. One night, Shizume saves Kiumi, who almost gets tricked into becoming a male companion, by taking him to his room to hide. Except, Kiumi gets the wrong idea and thinks Shizume is looking for a one night stand! He comes on to Shizume, only to find out that Shizume is also a top, and a way more sadistic one.
