Chu You and Pei Quchen, rivals in the business world, are on the surface tit-for-tat, but privately they have been lovers who have been ambiguously entangled for five years. Due to the worsening of cervical spondylosis and the crisis of the family business, Chu You drunkenly offered a share transfer letter in exchange for Pei Quchen to take over the company, on condition that he stayed with her for a week and ended the relationship. Pei Quchen saw through her hidden illness and vulnerability, intervened forcefully in her life, took good care of her before and after the operation, and gradually showed affection. As the truth about Chu You's bipolar disorder and family changes was revealed, the two turned from an underground love affair to a soul compatibility. In the end, Pei Quchen healed Chu You's physical and mental trauma, and the two established their sincerity in love and tolerance and spent the rest of their lives together.
