Liu Jiayin (played by Dilireba) is a shopaholic who spends money like water. Of course, all the money she spends is from her rich second-generation boyfriend. Finally one day, her boyfriend broke up with Liu Jiayin, and Liu Jiayin was officially declared bankrupt. In order to continue living, Liu Jiayin, who had no independent living skills at all, had to start selling her previous "inventory". Wang Jiwei (played by Guo Jingfei) is a drama actor. Although he has a decent job, he is notoriously stingy when it comes to money. In order to save money, he did everything he could, whether it was installing an independent meter or cracking the wireless password of his neighbor's house, as long as the ultimate goal was to save money, Wang Jiwei could do it. These two people with very different consumption concepts accidentally lived under the same roof. What kind of interesting life will be waiting for them?
