In high school, Lin Zhao was chasing not only the finish line, but also Xu Zhiyu's back on the track.
As teammates fighting side by side on the school team, they have established a deep "comradeship" through sweat on the training ground and shouting on the field. Lin Zhao cherishes every moment and buries the girl's thoughts deeply under this tacit understanding. She thought that they were evenly matched and would eventually see the farther scenery side by side.
But Xu Zhiyu's heartbeat was given to another person cheering for him outside the stadium. Lin Zhao's carefully prepared confession was rewarded with his confused and frank "I'm sorry, I only treat you as a friend." At that moment, the future of the runway suddenly blurred before her eyes.
Time flies. The girl who was riding high back then is now a doctor holding a scalpel and battling with death. The once brilliant sports student chose to take root on campus and become a physical education teacher who ignites the passion for sports in the next generation. The pleasantries at the class reunion were polite but distant. She heals the wounded and protects lives; he teaches and educates people, protecting dreams. They have all become "guardians", but the girl who wanted to protect him back then finally learned to use another way to heal her grand secret love that ended in nothing.
