Lu Qian and Ji Xu are college classmates and each other's first love. It may be the friction between stubbornness and control, or the collision between indifference and intensity. Their first love ends in failure. There are three seasons in this year, namely spring, summer and autumn. They fall in love in winter and separate in winter. Luan Shu witnesses this love and parting, which only adds to the sadness of autumn. Maybe, just try it once, and you don't need to fill up the regrets.
Concept: Regrets exist, and not all regrets need to be filled up.
