Zhu Xuanwen is a strikingly handsome, highly intelligent, and incredibly wealthy man who seems to have it all. However, he suffers from a neurosis stemming from a childhood car accident, believing he is Emperor Jianwen of the Ming Dynasty. This delusion leads him to neglect his real-life responsibilities, leaving his company’s management to others while focusing on building a palace and ruling his imagined empire.
Concerned for his well-being, those close to him seek professional help, hiring Luo Kaihuai, a mental health professional. Desperate for money, she takes on Xuan Wen's unusual case. As a member of the emperor’s "harem," Kaihuai faces challenges in trying to help Xuanwen, who consistently resists her efforts. She must navigate this complex dynamic to find a way to assist him.
