Description：Bai Lingling (played by Zhou Yutong), an ordinary female college student, has been secretly in love with her online friend "How Far Forever" for six years, but she dares not confess her feelings due to the insurmountable distance between them. At the same time, her graduation defense was defeated due to the disruption of a strange man, Yang Lanhang (played by Liu Yihao), and she was eventually delayed. The double failure of academic and love has put Bai Lingling into an unprecedented life dilemma. Yang Lanhang, who she identified as her "enemy", encouraged her to break the restrictions, continue her studies, and find another possibility in life. In the end, the two fought side by side, tackled the topic, and made great progress in scientific research results. Bai Lingling finally discovered that Yang Lanhang was the "How Far Forever" she had always loved.
