Ding Xiaoyu and her boyfriend Che Zijun have been in love for many years, and the former has always regarded the latter as the one who is destined to walk into the marriage hall hand in hand. However, by chance, Ding Xiaoyu discovered that Che Zijun was secretly dating a female netizen without telling her. Although they did not have any substantial development, Ding Xiaoyu still regarded this as a betrayal of their relationship. In fact, Che Zijun is a typical playboy who lingers in the nightclubs of feasting and revelry. In order to prevent the problem from happening, Ding Xiaoyu decided to implement comprehensive monitoring of her boyfriend. Under the crazy pursuit and blockade of his girlfriend, Che Zijun also countered the moves. The two showed their magical powers and fought in a series of battles, and even did not hesitate to pull their respective friends Park Ermin and Tong Guoqing to join the battle. Tong Guoqing is a single father with a child. During the coming and going, he and Park Ermin gradually attracted each other.
