You Da (played by Luo Zhongqian) loves cycling very much. He even represented Hong Kong and participated in international competitions with many masters. On the field, You Da met a man named Ye Huiting (played by Shen Zhenxuan). He was a powerful enemy that You Da could not defeat, but he was also a confidant who cherished and connected with him. However, one day, Ye Huiting suddenly left without saying goodbye and never heard from him again. At the same time, You Da's family encountered an accident, which forced him to give up his ideal of becoming a racing driver and switch to become an accountant to accompany his mother. In a blink of an eye, a few years later, You Da and Ye Huiting, who is now also an accountant, met unexpectedly. The two companies happened to be in the same building. What You Da didn't expect was that the reunion did not bring joy. The indifference and rejection in Ye Huiting's eyes puzzled him.
