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 Kang Joo, the current heir to Taeyang Group, had been arranged to marry heiress Jang Yi Kyung when she suddenly disappears. The Jang family, desperate to maintain the engagement, finds a poor village girl, Na Doo Rim, wholooks exactly like Jang Yi Kyung, and convinces her to masquerade as the missing heiress in exchange for a sizeable sum of money.
Na Doo Rim’s sweet and sunny personality captivates Choi Kang Joo 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?
