This drama tells the daily co-renting life of Gu Cheng, an impoverished and self-belittling top student, and Xia Yuan, the Jingda campus belle and landlord. Xia Yuan has been secretly in love with Gu Cheng for years, and under the guise of co-renting, she sets bizarre rules to start a hardcore reverse pursuit. Facing the composite entanglement of ex-girlfriend Lin Weiwei and the poaching provocation of a rich second-generation heir, the dull Gu Cheng gradually opens his heart under Xia Yuan's meticulous care and direct offensive. After a series of hilarious and ambiguous tug-of-wars such as sharing a bed due to a stomachache, getting soaked in the bathroom, and being forced into marriage through a game, Gu Cheng finally breaks through his psychological defense line, turns from passive to active, makes a domineering promise to give full security, and stages a sweet reverse wife-chasing story of mutual rushing towards each other.
