Li Haoran, the descendant of Ghost Doctor Valley, went down the mountain to break off his engagement, but he used his acupuncture skills to save Jiangcheng boss Lin Guodong on the train. Unexpectedly, the person who wanted to break off the engagement was Lin Guodong's granddaughter Lin Qingyao - the two had exchanged ugly photos and disliked each other. After moving into the Lin family, Li Haoran relied on his superb medical skills and extraordinary courage to help Lin Qingyao resolve the company's crisis, deal with provocations from love rivals, and slap snobbish relatives in the face. The two gradually fell in love while bickering and sharing adversity. What was originally a farce of breaking up the engagement eventually turned into a two-way love affair.
