Xia Man, a young bodyguard who has not been married for several years, met a "hero" who was a chivalrous and righteous man in the process of chasing a flower picker. He fell in love at first sight and thought that the hero was the son of the Duan family, so he married her through a ruse. The mother-in-law, who is rich but not educated, wants her son to marry an educated daughter-in-law and help her son who "failed" the imperial examination to reach the peak of his official career. The mother-in-law was confused when she saw her daughter-in-law climbing a tree and fighting. Xia Man married and found out that the Duan family's son did not know martial arts and was not a hero at all. His mother-in-law was more fierce than him. Should he stay and continue to find the truth or run away?
