Xu Tan (Bai Jingting) is a very introverted boy. Under the influence of his grandfather who loves table tennis, Xu Tan also began to learn to play table tennis. Just when he was about to give up, an experienced coach discovered Xu Tan's extraordinary talent. Through systematic and rigorous training, Xu Tan's skills improved by leaps and bounds, and he soon became the mainstay of the team. Yu Kenan (Xu Weizhou)'s father was a national table tennis player. Under his father's guidance, Yu Kenan's skills are naturally not to be underestimated, and he is even called a genius. His character is also affected by this and is unruly and uninhibited. These two boys with very different personalities met in the team. They saw the special features that they did not have in each other, competed with each other, and made progress together.
