Su Jin, a 25-year-old jewelry designer, encountered a drastic change in her life on her wedding day - the groom-to-be, Lin Zexi, mysteriously fell and died. Surveillance showed that she was the last person to recommend him. When a DNA test revealed her identity as the adopted daughter of a wealthy family, the gilt jade pendant left by her biological mother implicated the blood debt of the island development case twenty years ago. In order to find out the truth, she was forced to enter into a contract marriage with Huo Linchuan, the leader of the Huo Group. Little did she know that the pale young man who transplanted bone marrow for her in the hospital bed five years ago had already written her fate into the chess game.
