Born into a rich family, Go Hee Soo (Kim Jung Eun) has lived the life of a veritable princess, showered with love and sheltered from the real world. Through some rather odd turn of events, she meets playboy Kang Woo Jin (Jung Jun Ho), who just returned from England. The two get off to a bad start when the bumbling princess causes Woo Jin to lose an important contract. He's not exactly Prince Charming, but Hee Soo can't help being drawn to Woo Jin, whose carefree ways introduce her to a life she has never known. This burgeoning relationship is complicated by the entry of her longtime friend Chan Ho (Kim Heung Soo). She may have always thought of him as a younger brother, but he has liked her for many years.
