During his childhood, Masamune Makabe was spurned by a wealthy and stunning girl named Aki Adagaki, who dubbed him "Piggy" because of his plumpness. Heartbroken, he dedicated himself to rigorous exercise to transform his looks. Today, as a striking yet vain high‑schooler, Masamune is resolved to take revenge—he intends for Aki to become infatuated with him and then dismiss her when they next cross paths.
Unexpectedly, Masamune learns that he has enrolled in Aki"s school. Launching his scheme, he first attempts to connect with the so‑called "Brutal Princess," but all his early endeavors fall flat. Astonishingly, as he inches closer to retribution, a cryptic note arrives that calls him by his former nickname. Unless Masamune uncovers who sent it, his plot will collapse before it even begins.
