When 27-year-old Wen Xi was in a stable life, she learned that she was accidentally carried by the wrong child when she was born, and her life suddenly turned around. She was forced to recognize her biological parents, and her marriage contract was replaced by Shang Shen, the cold and taciturn leader of the Shang family. The two were originally in a contractual marriage bound by interests, and agreed not to disturb each other. But after marriage, Shang Chen changed from his cold and aloof attitude and took good care of her and tried his best to protect her. Faced with family conflicts and identity troubles, Wenxi gradually opened up her heart under Shang Chen's gentle protection. From alienation to heart-warming dependence, she finally broke the shackles of the contract and became dependent on each other. Wenxi also completed her self-growth and harvested perfect love.
