Tao Kan (played by Lu Yi), a young web designer, met Liu Cuiyun (played by Jiang Hong) in a competition. The two men argued over a work and refused to admit defeat, becoming "enemies".

Tao Kan and his friends, Hong Kong youths Jialin He (played by Chen Musheng) and Yang Huimin (played by Michelle Ye), set up a youth online marketing company, determined to make a difference in this emerging industry. Unexpectedly, Yan Xin Real Estate Company and the youth company where Cui Yun works are in the same office building. Tao Kan and Choe Yun have a narrow road, and they taunt each other as soon as they meet.

Tao Kan felt that the girl in front of her, although beautiful and lovely, had a little bad temper. In fact, Cui Yun is a kind and naive girl. In this building, she has two suitors: one is a big boy with avant-garde style and free personality, Zhou Wei (played by David) of the youth company; The other is Lu Naisheng (played by Kevin Cheng), the manager of Daya Jewelry Company. This person is eccentric and has a low temperament, and even the way of pursuing Cui Yun is different.
