It tells the dual love story of scientist Yang Lanhang and Bai Lingling in the virtual and real world. The two met on the Internet in their early years. After Yang Lanhang returned to China, he was admitted to T University as a doctoral student. Unexpectedly, he ran into Bai Lingling, the “friend online" he was thinking of, and disrupted her carefully prepared thesis defense. In order to make up for it and to pursue Bai Lingling smoothly, Yang Lanhang continued to become a friend online to solve Bai Lingling on the one hand, and arranged Bai Lingling into the laboratory on the other hand. The misunderstanding between Bai Lingling and Yang Lanhang gradually resolved, and the two fought side by side, tackling tough issues, and sympathized with each other.
