Han Sang Eun is a girl who immigrated to Australia at a young age. Returning there upon completing her law degree in the United States, she introduces her American boyfriend, Alex, as the man she intends to marry. Her father, who still follows Korean customs, strikes a deal with Sang Eun. She will be allowed to marry Alex if she agrees to move to Korea to live with his friend for a year. The catch: she will also be living with her fiancee, Kim Yeo Jun, a doctor who has no intention of marrying. With a shaky start, the two begin their 'romance' in an attempt to ward off their parents. But as they start to fall in love, trouble shows up in the shape of admirers, misunderstandings and secrets.
