Riley is 17 year old high school girl. She's an average girl and gets picked on by everyone. Her family died in an accident and decided to move to Seoul for a new start. Riley only had 2 best friends Sarang and Nina and they warn her about the school she was transferring to. She never thought that the high school most popular boys would turn their attention to her. She just wanted her life to be better for once with her beat friends. All Riley had in her mind was "Not again"
