When Lin Weiguang, an introverted and sensitive art student, met Gu Chenxing, a genius from the mathematics department, for the first time among the bookshelves in the library, she would never have imagined that the "Atlas of the Starry Sky" she accidentally pulled out would become the beginning of illuminating her entire youth.
The glimmer of light coming from a new school, with the shadow of the past, is trying to find its own corner under the brush. But Gu Chenxing, the campus male idol who was dazzling on the court and calm in class, had a gentle side unknown to everyone: the sound of the piano in the empty music classroom every Wednesday evening, the clumsy painting he learned just to soothe a stray cat, and... The focused eyes he only showed to her.
Starting from the cooperation at the campus cultural festival, a "Starlight Diary", a kitten rescued together, and the company of the observatory late at night, two hearts slowly approached each other on the scroll of youth. Many years later, when Shimmer's song was heard by more and more people, and when Chenxing's research shined on the international stage, they finally understood: the most beautiful thing about youth is not the sunshine without haze, but the presence of someone who is willing to be your starlight and wait with you for every dawn.
