Ki Seo-Yun is a bright talented girl. SHe's the very definition of natural beauty and can make any boy fall to his knees, but she's not like that. She's quiet, she wears only black clothing, she rarely smiles, she has no family, she has lots of talent that is just waiting to be discovered, she's good at EVERYTHING she tries, she has another job while working as an idol for YG, but you'll figure out later, she used to get bullied for being too pretty and not taking advantage of that, she is called emo and other names, she still wears braces and glasses.
