When the family butler discovers that her daughter, Cheng Yun, has been enduring long-term abuse after marrying into the Yang family, the tycoon secretly promotes Cheng Yun's husband, Yang Chao, and invites him to his birthday banquet. At the banquet, Qiao Tianya witnesses her daughter's suffering—and just as she prepares to reveal their kinship, the tycoon suddenly collapses, critically ill.
