Yingxiu (Chun Zhengming) is a man with a small heart like a needle tip. He likes to be a man who is very calculating. He can not care about his face for a little bit of profit. Therefore, he has no charm at all, and he is a 100% love insulator. Of course, for Yingxiu, sexy and hot women are no more attractive than discount coupons in supermarkets. One day, in a cafe, Yingxiu met a female clerk named Xizhu (Kim Minzhen), and Yingxiu found that she was hopelessly in love with her. Unable to suppress the feelings for Xizhu in his heart, Yingxiu finally decided to confess. What he didn't expect was that Xizhu was also quite attracted to him. The two people who were in love with each other soon came together and entered the palace of marriage hand in hand. Yingxiu felt that he might be the happiest and luckiest man in the world. One day, Yingxiu accidentally found a photo album full of photos of Xizhu dressed as a sexy electric girl. Yingxiu, who discovered his wife's secret, decided to thoroughly investigate the truth of the incident.
