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...
Kachi had a sweet side that 
she only showed to you,
،لدى كاتشي جانب لطيف أرته لك فقط
Kachi-san hat ihre nette Seite nur dir gezeigt,
Kachi solo se mostraba amable contigo.
Kachi solo era amable contigo.
Kachi n’était gentille qu’avec toi.
Kachi ha un lato dolce che mostrava solo a te,
Kachi-san tem um lado doce
que mostrou apenas para você,
С тобой, в отличие от остальных,
Кати была милой,
