Kim Namjoo has three boyfriends. One is her childhood friend, another is a small town boy, and the last is her fiance Oh Sehun. Namjoo is forced to get pregnant when they marry, but that's the least of her problems. Her mother is dead, and their fathers hold the key to the mystery behind it. Sehun's older brother is after Namjoo for his own benefit. And Namjoo's younger step-sister now regrets letting go of her previously arranged marriage to Sehun.
