Jia En (played by Ren Rongxuan) and Ren Wei (played by Shi Yuanjie) are childhood friends who have been playing together since they were young. They both took the college entrance examination. What Jia En didn't expect was that although her grades were always better than Ren Wei, Ren Wei was admitted to the university of her choice, but she failed. After sending Ren Wei away, Jia En, who felt helpless, decided to go to Taipei to start a new life there. Because her parents were away for something, Jia En decided to go to Chengdong University to join Ren Wei, but Ren Wei didn't show up for a long time. Instead, on the court, Jia En met Rukawa (played by Li Guoyi), a star on campus. In the accidental encounter, Rukawa and Jia En had contact again and again. The throbbing in her heart forced Jia En to start facing up to her feelings for Rukawa, and also made her begin to reflect on her and Ren Wei's future.
