政宗くんのリベンジ

Bullied as a chubby kid and nicknamed Pig's Foot by the wealthy Aki Adagaki, Masamune Makabe spends years dieting and training into a handsome, vain teenager. Transferring into Aki's school, where she's known as the Cruel Princess for shooting down every boy who confesses, he hides his old identity and plots to make her fall for him so he can reject her in turn. Her servant Yoshino Koiwai, who seems to recognize his nickname, becomes his uneasy ally.
