Time and You, Always tells the story of the ambiguous, turbulent youth shared by Chen Yi, a top student in his senior year of high school, and Yu Jingchen, an art student. Chen Yi, a rational and composed mathematical genius, has been quietly paying attention to his cheerful, art-loving deskmate, Yu Jingchen, for a long time. But burdened by his family's expectations and the pressure of an early university admission, he keeps his feelings in check and never dares to cross the line. As Yu Jingchen tests the waters and gradually draws closer, she begins to realize how he feels, but his hot-and-cold attitude leaves her confused and hurt.
Through arguments and compromises, the two gradually come to understand each other's inner worlds and hidden family pain. After his father's death, Chen Yi falls into even deeper turmoil, while Yu Jingchen quietly offers him warmth through her companionship and art. Wei Jia's bold pursuit and the arrival of transfer student Lin Mu make Chen Yi feel increasingly threatened, until he loses control and gets into a fight. It is only after Yu Jingchen nearly falls from a building that he finally faces his feelings, breaks free of his self-imposed restraints, and confesses to her.
Set in classrooms, art studios, and on the sports field, the story follows their wavering and growth as they navigate schoolwork, dreams, and the first stirrings of love. At last, beneath a banyan tree during graduation season, they confirm their feelings for each other. Their friends also set off toward their own futures, bringing this story of youth to a hopeful close. This is a heartwarming school story about unrequited love, companionship, breaking free, and making choices.
