In the winter of his first year in high school, Maru Sueharu fell in love with Kachi Shirokusa, a genius novelist who happens to be his classmate. But since it was his first love, time only continued to pass by while he could do nothing. As his so-called friend Tetsuhiko chides him and his childhood friend Shida Kuroha teases him, he overhears his crush Shirokusa saying she has a boyfriend now. His heart broken before he could even confess his feelings, Sueharu is devastated. Then Kuroha proposes that they get revenge...
Don't be dumb. Obviously, they were

No seas idiota,
todas son de otro instituto.

Non essere sciocco.
Ovviamente vengono tutte da scuole diverse.
Não seja tolo, é claro que
todas são de escolas diferentes.
Не тупи! Ясное дело,
они все из других школ.
