もう好きでしょ、オレのこと

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.
