The introverted, sensitive transfer student Su Wanxing is used to hiding herself in the corners of a crowd, until one summer in her first year of high school, when the cicadas never stop singing and she stumbles into the world of the cool, top-ranking student Lu Shiyan.
He is quiet and reserved, yet the most attentive of guardians: he silently hands her his notes, patiently explains problems during evening study sessions, and saves his warmth for her when the wind rises.
From awkward deskmates to secret crushes, from not daring to get close to standing firmly by each other's side, Su Wanxing slowly grows brave in his tenderness, while Lu Shiyan lets go of all his reserve because of her.
The classroom lights, the evening breeze on the sports field, the library at dusk: every ordinary moment of their three years of youth holds the tenderest first stirrings of love between a boy and a girl.
When the evening breeze seems to tread softly on the clouds and starlight spills across the windowsill, they finally understand that their summer encounter was fate, written for them once in a lifetime.
