Song Zhiwan, who has been up and down in the workplace for many years, is sober and independent, but has long been tired of relationships. By chance, she met Jiang Yu, a young man who loved badminton. The two people's identities and experiences are very different, from testing each other to gradually getting closer. On the playing field, young men work hard for their dreams; in the workplace, women face pressure and move forward step by step. They support each other and save each other across age and secular perspectives. Let go of your impetuosity, put aside the criticism from the outside world, grow side by side on the road of pursuing dreams and companionship, and finally understand that the best love is to become a better version of yourself, stay together tenderly, and walk together year by year.
