Choi Jinri had always been the bad girl to everyone's eyes but Minho saw her differently. And maybe that was the main reason why Jinri started liking him. One glimpse of his presence could make her whole world lighten up. And that was the problem, she continues to like him so bad even though she knows that she can't. She can't because he's engaged. And even if he was, she still continues to harbor this feeling for him. And when his fiance, Choi Sulli (Jinri's twin sister) dies from an accident. Her father desired to make her as the replacement.
