Wen Yutang, an elite who has returned from the Ivy League school, competes with Chen Haiqing, his idiot colleague, for a 3 billion smart home project. Director Zhao was even more optimistic about the married Chen Haiqing. In order to win the project, Wen Yutang agreed to marry Zhou Yan, who had just graduated from the housekeeping management major. After the marriage, Zhou Yan took care of all the housework, leaving Wen Yutang to concentrate on the sprint project. When visiting relatives, Zhou Yan relied on his housework skills to slap his uncle's family in the face who loved to compare. The project shined at Asian exhibitions, Wen Yutang was promoted to general manager, and Chen Haiqing, who had colluded with hackers, was fired. She hired Zhou Yan as the company's special housekeeping manager, and the two gradually moved from contractual partners to true love.
