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...
I thought I was keeping him around, 
but he was just keeping me around...

Yo lo tenía como segunda opción,
pero la segunda opción era yo.

Pensei que eu o manteria por perto,
mas era eu quem estava sendo mantida...
Думала, держу его при себе
на всякий случай, а всё наоборот...
