Zhu Xuanwen (played by Wanyan Luolong) is a rich second-generation who was born with a golden spoon in his mouth. After a terrible car accident, he seemed to have a broken head. He actually believed that he was a prince who traveled back to the modern era from ancient times. He even gave up the right to operate the family business and started to build a palace in the suburbs, and lived a leisurely retirement life. Luo Kaihuai (played by Zhuang Dafei) is a psychologist who is still in the internship period. Although he has not been in the industry for a long time, Luo Kaihuai's medical skills are deeply trusted by patients. However, in life, Luo Kaihuai's brain has always been in a state of lack of a tendon. He is careless and confused, and can hardly take care of himself. Under such circumstances, Luo Kaihuai became Zhu Xuanwen's attending physician. Zhu Xuanwen certainly resisted Luo Kaihuai's "invasion" to the end, but the high medical expenses made Luo Kaihuai unwilling to give up this opportunity to make money easily.
