At the age of eighteen, Su Nian met Lu Yanzhou.
Before meeting him, she was a warm little sun to others, but she couldn't cure her own loneliness late at night. After meeting him, she realized that there really was someone in this world who made you want to become a better person and made you finally dare to take off all disguises.
Lu Yanzhou's first eighteen years of life were an isolated island without spring. His mother's departure and his father's harshness made him learn to use indifference as armor to keep everyone out of the world. Until that girl appeared, with the sweet smell of sweet-scented osmanthus cake and a smile that didn't know the heights of heaven and earth.
He thought he was hiding it well.
It was so good that no one knew that he would read every update of her late at night, so good that no one knew that he collected every cookie she fed, so good that even she herself didn't know——
The netizen "Little Sun" who gave her warmth and courage through the screen during her darkest adolescence, and the light that brought him out of the edge of depression, was the girl in front of him who foolishly wanted to make him laugh.
The sycamore leaves fall and grow again, and they fall again after they grow.
From the startling glimpse in the library, to the warm waiting in the cafeteria late at night; from walking side by side on campus, to the sea of stars where everyone rushes towards their ideals.
It took them their entire youth to finally confirm——
It turns out that the best love in the world is not about who lights up who, but that we happen to be each other's light.
