Lee Jae In is an entitled third-generation chaebol. He is handsome, intelligent and wealthy, all of which has predictably made him a touch arrogant. And while his uncompromising professionalism means he is nothing but pleasant to the customers of the hotel he owns, etiquette and politeness are not things known to him in his personal dealings. However, he is in for a rude awakening when he realizes that his grandfather has not left him the entire inheritance he is so fond of. Instead, that key to that fortune has gone to Kim Da Hyun, a strong-willed elementary school teacher who is a complete stranger to Lee Jae In. And perhaps being a stranger isn’t even the strangest aspect of Grandpa’s will: in order to get his inheritance from her, Lee Jae In must marry Kim Da Hyun and live with her for six months. Should he refuse or fail to do so, our chaebol star can forget about ever getting that one thing that actually makes him a chaebol. Can a marriage brought upon by someone else’s force of will ever blossom into something more meaningful, or will the arrogant chaebol pack up with his inheritance as soon as this contract of matrimony runs out?
