From a young age Kim Mi Hyun has always known one thing: That her eldest sister, Kim Mae Hyun, would marry someone picked out by her parents. But five years after Mae dies, losing her fourteen-year battle to leukemia, that engagement is null and void and her mother wants to win it all back by marrying Mi Hyun off to an influential family. While it's now only Mi Hyun and her older sister, Jung Hyun (who's already married herself), what surprises Mi Hyun is not that her mother would try it once more... But that she'd have Mi Hyun marry her dead sister's fiance, Dong Young Bae, otherwise known as Big Bang's Taeyang, who also just happens to be one of the idols she works alongside with at YG Entertainment as an established artist herself. As being nothing more then a place filler in the eye's of her family and mostly herself, can she overcome the fact that she's nothing more then her dead sister's memory and save her marriage before it crashes and burns?
