In the middle of winter eight years ago, a sudden separation tore apart the peaceful and stable life of the Qi family.
The sensitive and fragile girl Qi Shengyu is trapped in the pain of the past, deeply depressed, and isolating the world with silence; the calm and gentle brother Qi Yuheng loses his childishness overnight, takes up the responsibility alone, and silently protects his scarred sister.
Entering the third grade of junior high school, Qi Yuheng met his lonely and unruly classmate Shen Yuye. Two equally lonely teenagers slowly get closer to each other on the campus where the four seasons pass. Born in spring and growing in summer, harvested in autumn and stored in winter, they walked through the four seasons of green campus and faced the breakup of their original family, the turmoil of family reorganization, and the confusion and pain of youth.
The broken past, secret bonds, and long companionship are all hidden between the evening breeze and the mountains. They redeemed each other in the barren years, spanning spring, summer, autumn and winter, and headed for a gentle and long-lasting growth.
Intent: Young people redeem each other in the changing seasons and broken past, and rush towards warmth in their youth.
