Чин Би Воль

Bi-wal is the friend of Dong-young and attends the same high school. They are very close and are often confused by other students to be homosexual or "boy-lovers". He is the only character who suspects Dong-young to be the Princess. He sometimes likes to grope Dong-young even after "finding out" that she was a girl (he had already known that she was a girl before he accidentally saw her bound chest). Bi-wal is also shown to be something more than a human.
