Lin Wanxing, as a senior member of the company, was given a "problem intern" Gu Yanchen by his boss. He was clumsy and full of mistakes, filled out reports incorrectly, kept meeting minutes off track, and even lost important contracts. Lin Wanxing followed him every day to clean up the mess, and he was so angry that he wanted to resign. Just when the company was on the verge of bankruptcy and all employees were facing unemployment, the good-for-nothing intern who gave her a lot of headaches appeared at the acquisition signing site in a high-end suit and as the prince of the group. It turns out that he came to inspect the secret service, and she was the only senior who "will never leave" him. After the acquisition, Gu Yanchen's painting style changed suddenly, and he pressed Lin Wanxing step by step: "Senior Lin, you used to help me clean up the mess, how about I spoil you now?" A reverse love relationship between superiors and superiors in the workplace kicked off in the intertwining of "pretending to be a pig and eating a tiger" and "marriage first, love later".
