.Itsumi Tachibana hates fighting. He's a student at a fancy high school who loves visiting cat cafes and collecting kitty-themed merchandise. Despite that, he looks like a gangster, which alienates him from his classmates, making him a magnet for unsavory characters outside of school. One day, the unthinkable happens: the popular, brilliant, and beautiful student body president, Seima Takajou, professes his love for Itsumi! This is a romance between complete opposites: a popular hot guy and his scary-but-sweet Cinderella!

Renta: At a high school full of delinquents, Leo Shishiyama, a boy who looked cute but was the best fighter, is puzzled. Takeru Kurosawa, who had constantly challenging Leo to fights that ended up in a draw, has sent him an eighth challenge letter. Leo likes winning, but he doesn't particularly like fighting, and enjoys gorging on strawberry rice cakes, his favorite snack, much more. He tries to ignore Takeru, but bumps into his beautiful little sister on the street, who shows him kindness. If he can beat Takeru, maybe he can make a move on her! Leo faces Takeru, but who comes out victorious...?
