In the 19th century and on the night of her wedding day, Park Yeon-Woo's (Lee Se-Young) husband tells her he has suffered from a heart disease for a long time and apologizes. He spits out blood and dies. She is devastated by her current situation. Making matters worse, Park Yeon-Woo gets kidnapped by a man and is thrown into a well. The next moment, she opens her eyes and sees her husband in front of her. She is now in present day Seoul, South Korea. The man who saves her from the swimming pool is Kang Tae-Ha (Bae In-Hyuk). He is the successor of SH Seoul Corporation. He doesn't mind opening himself up to others due to his heart disease and trauma that he suffered from in his childhood. He is a logical person and not interested in having a romantic relationship, but his ill grandfather tells him that he wishes to see his wedding before he dies. Kang Tae-Ha asks Park Yeon-Woo, who he saved, to enter into a contract marriage.
