Being an exchange student is supposed to be fun. A new experience. That is, until your "adoptive" parents' son is attractive, along with his 6 other best friends. Then your supposed stress-free home life is turned into constantly walking on egg shells.

You and Kim Yugyeom hate each other so much. He is dating your best friend but because of your parents, Yugyeom is forced to marry you. Is the marriage going to fail miserably?
