Kirishima and Hayasaka are two classmates who have a secret relationship in public.
In their school life they pretend that they don’t know each other, but behind the scenes there is much more to them than people can imagine. The two get into a relationship that is difficult to break and ends up being impure, unhealthy, and complicated, as the relationship between them was nothing more than an affair that simply created a love triangle before Kirishima’s first love and his second love.
