Yuzu Asahina, a high school girl, drops out to take a live-in job at an all-boys dorm to stay close to her beloved younger sister. To blend in, she disguises herself as a boy and dives into dorm life surrounded by a group of quirky, handsome guys. Among them, Ryuga Fujiwara stands out, sparking Yuzu’s heart as she navigates her secret identity.

Usagi has carried an ideal image of her first love for years and wants a relationship with someone who will love only her. Then the boy she once admired returns as her new stepbrother. He is smooth, pushy, and far more experienced than the person she remembers. He keeps telling her he likes her and refuses to respect the distance she wants to keep. Their life under one roof turns into a fast, teasing clash between her ideals and his relentless affection.
