Seventeen-year-old Shi Chuan meets sixteen-year-old Su Meng, and they become the youngest mixed doubles pair in table tennis.
They share the same dream: to earn a place among the top players and compete in the 2024 Paris Olympics.
In their everyday interactions, the seemingly aloof and cocky Shi Chuan proves to be a thoughtful big brother through and through. Su Meng has said more than once that Shi Chuan is the best boy in the world, and they are both drawn to each other.

At last, they meet at the summit and win the Paris mixed doubles gold medal.
They think it will all be over then, but their story becomes a sensation. They are followed by obsessive fans and lose all privacy.
The public's expectations take a heavy toll on Shi Chuan. After Paris, he suffers a string of defeats and is then attacked online.
Shi Chuan begins to give up on himself. Can he overcome the demons in his heart and return to his peak form?
The answers are all in the story.
