When she discovers her boyfriend's infidelity on Christmas Eve, Sam Sun accidentally enters the men's bathroom in her grief. There she crosses paths with the young and arrogant owner of a small French restaurant, Hyun Jin Heon. Not only does he end up hiring her when they next meet, a debt ridden Sam Sun is forced to accept when he later asks her to pose as his new girlfriend in order to throw off his mother.
