In order to inherit everything his grandfather was going to leave for him, Jae In would have to enter into an engagement contract with Kim Da Hyun, a lovely school teacher with one of the sweetest of personalities in the world. Forced to agree with his grandfather’s terms, Jae In and Da Hyun have no choice but to endure the next few months as best they can.
