As a child, Masamune Makabe was rejected by Aki Adagaki, a wealthy and beautiful girl who gave him the nickname "Piggy" due to his overweight. Heartbroken, Masamune dedicated himself to working out in order to improve his appearance. Now a handsome yet narcissistic high school student, Masamune is determined to seek revenge against Aki by making her fall deeply in love with him and ultimately rejecting her once more. To his astonishment, Masamune discovers that he has been transferred to the same school as Aki. He begins by trying to win over the "Brutal Princess," but fails miserably at first attempts. However, when Masamune finally makes progress towards his vengeance, he receives a mysterious letter addressed to him using his old nickname. In order for Masamune's plan to succeed, he must determine the identity of the sender before it even begins.

The anime adapts the first 29 chapters of the manga.
