Angels have wings. Demons have horns. But what do fuck boys have?

Bangtan Sonyeondan. A group of guys who has a story behind every mask they put on and show to everyone. Every member fights a battle no one is aware of. They're fighting much more than what other people see underground, and that's something only the people whom they let into their walls see. Choi Eunmi. A girl who's known to be quiet and smart as she is one of the scholars in her school and always gets top grades. She lives in a mansion with such a wealthy family friend supporting her and her mother, but she herself, is fighting a battle every single day. A past she had always wanted to bury but her fate gets entangled with a Bangtan member and all the things she had tried so hard to avoid was now becoming inevitable.
