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...

– Kuro, arrête !
– Pourquoi ?
K-Kuro! Non dovremmo farlo!
K-Kuro! Não devemos fazer isso!
К-Куро! Не стоит этого делать!
