Taeyang Group is the largest conglomerate in South Korea but the Choi family, who runs Taeyang, has supposedly been under a hundred-year-curse - the first bride of the eldest son will always die. Choi Kangjoo, the current heir to Taeyang Group, had been arranged to marry heiress Jang Yigyeong when she suddenly disappears. The Jang family, desperate to maintain the engagement, finds a poor village girl, Na Doorim, who looks exactly like Yigyeong, and convinces her to masquerade as the missing heiress in exchange for a sizeable sum of money. Doorim's sweet and sunny personality captivates Kangjoo but he has no idea about her hidden identity nor about his family's hundred-year-curse. What will happen when these two people end up falling in love with each other?
