The two developed feelings for each other while training. Dai Ran was forced to retire because of a back injury and eventually decided to stay on as a coach. After narrowly missing out on the championship at an international tournament, he was mocked by his opponent. He threw himself into training with everything he had, eventually aggravating his back injury. But the next international tournament was only a year away, so he had no choice but to place his hopes in the unruly kids he was training.
When Yu Yi was seventeen, he came across Dai Ran on a short-video platform and thought Dai Ran looked handsome with that focused gaze during a match. Later, thanks to his talent and hard work, he joined Yr, the esports club where Dai Ran played. After Dai Ran retired, Yu Yi became the new team captain. During their training sessions, their repeated physical contact and playful teasing made Yu Yi's heart beat more and more uncontrollably, until he realized he was in love with Dai Ran.
After one match, Yu Yi confessed to Dai Ran while tipsy. Dai Ran, who only had eyes for winning championships, struck a deal with him: if Yu Yi could secure a spot at the international tournament and win the championship, Dai Ran would agree to be with him. From then on, Yu Yi trained even harder. Watching Yu Yi push himself more and more each day, Dai Ran felt increasingly worried for him. At last, he understood his own feelings. After Yu Yi secured a qualifying spot, Dai Ran started giving him little treats now and then.
Theme: Win the match, and win your heart too.
Is it King of Glory? Ha ha ha ha
