Young online designer Tao Kan (played by Lu Yi) met Liu Cuiyun (played by Jiang Hong) in a works competition. The two had an argument over a piece of work, were both不服气(unwilling to lose/不服气 is difficult to translate directly), and became "sworn enemies".
Tao Kan, together with his good friends - Hong Kong youth He Jialin (played by Chen Haomin) and Yang Huimin (played by Ye Xuan), established a youth online marketing company, determined to make achievements in this emerging industry. Unexpectedly, the Xinxin Real Estate Company where Cuiyun works is in the same office building as the Youth Company. Tao Kan and Cuiyun, sworn enemies with little room to evade each other, would mock each other whenever they meet.
