In such a big city, Xiong Dan (Du Chun) is just an inconspicuous little courier. Although he has a grand dream of martial arts in his heart, in fact, he lives an exhausted life every day. Not only is he short of money, but he is also excluded by his colleagues at work. In an accident, Xiong Dan met a girl named Yang Mei (Yao Di), who is a very hot-tempered girl with a quick mind. A conflict arose between the two because of a small misunderstanding. Yao Di's mother has always hoped that her daughter can get married early, which has become Yang Mei's heart disease. The appearance of Xiong Dan gave Yang Mei the hope of getting married. Although she felt that Xiong Dan did not meet her standards for choosing a spouse, as time went on, his sincerity and kindness gradually moved her. Although Xiong Dan finally won Yang Mei's heart, he still had to face the assessment of his prospective mother-in-law.
