In the 19th century, on the night of her wedding day, Park Yeon Woo's husband died after revealing that he had suffered from a heart condition for a long time. She is devastated, but before she can even mourn her husband, she gets kidnapped by a man and is thrown into a well. The moment she opened her eyes, she saw her husband before her. Transcending time, space and death, she is now in present-day Seoul, South Korea, and the man who saves her from the swimming pool is Kang Tae Ha, who looks a lot like her dead husband from the 19th century. Kang Tae Ha is the successor of SH Seoul Corporation. He does not like opening himself up to others due to his heart disease and the trauma that he endured in his childhood. He prioritizes logic over emotions and is uninterested in having a romantic relationship, but his ill grandfather tells him that he wishes to see his wedding before he dies. In the hopes of making his grandfather's wish come true, Kang Tae Ha asks Park Yeon Woo to enter into a contract marriage with him.
