Everyone says Su Nuoyuan has poor natural advantages: short arms and a weak foundation, with no chance of achieving good results.
She fails to qualify for the junior tournament, her coach has no faith in her, and those around her secretly mock her.
She grits her teeth and spends day after day at the gym, sweat soaking through one training shirt after another.
Then, at training camp, she meets a left-handed prodigy.
He watches her clumsy footwork with a cool gaze, yet late at night, he quietly stays behind at the training court to practice against her.
"Keep up with your footwork. Don't give up so easily."
The round-faced girl swings her racket and turns the tables against the odds. Step by step, she makes her way onto the court that belongs to her, and into the boy's heart.
