Chen Yu, who comes from a top-tier wealthy family, in order to escape from the control of his family, concealed his name and entered a creative studio that was on the verge of bankruptcy. Here, he met Lu Chuan, a planner who bears the burden of the family, Shen Xiaoyu, an intern who firmly believes that "hard work can do everything", and Wu Peng, a small boss who is cunning in order to survive. Chen Yu relied on resources to secretly turn around the fate of the studio, and was regarded as a "lucky koi" by everyone. However, when the true identity is accidentally exposed, the past warmth and mutual help are instantly torn apart by suspicion, jealousy and demands. On the one hand, there is the return order forced by the family to sever ties, and on the other hand, there are doubts from friends about "pretending to be innocent and taking advantage of others." Chen Yu must make a choice between the illusory life given by the golden spoon and the real emotions that bite like gears, and his friends must also re-examine their beliefs in "fairness", "struggle" and "class".
