Shadows Of A Summer Day by Angelita N. P.

At fourteen, Lin Sheng falls quietly in love with Xu Xiachuan, her older brother's friend. He is kind to her when others tease her, gives her a piece of white milk candy, and leaves behind a memory she cannot quite explain. When Xu leaves Ningcheng for university in Yihe, Lin Sheng begins folding paper stars and storing them in a glass bottle, turning an innocent childhood feeling into a private promise to wait.

Three years later, Lin Sheng is preparing for the university entrance examination when she hears that Xu may already have someone special in his life. Rather than abandon the future she has worked toward, she chooses Yihe University and decides to build a life there for herself.

But arriving in Yihe brings her closer to the person she has spent years missing, and closer to misunderstandings she never expected. As Lin Sheng grows into an independent young woman, Xu begins to see her differently. Their relationship is complicated by distance, family expectations, his painful family history, financial burdens, and the fear that loving her means taking on responsibilities he may not be ready to bear.

Around them, university friendships, illness, academic pressure, family gatherings, and the ordinary routines of growing up gradually reshape what they mean to each other. When Xu discovers the bottle of paper stars Lin Sheng has kept hidden for years, the feelings both of them have avoided can no longer remain unspoken.

But recognizing love is only the beginning. They must learn whether love can survive the weight of the past, the uncertainty of the future, and the difficult choice to stand beside another person without trying to protect them from every hardship.

From a summer afternoon in Ningcheng to university life in Yihe and, eventually, a shared future, Shadows of a Summer Day is a slow-burn romance about growing up, waiting, misunderstanding, and learning that some of the deepest forms of love are built quietly, one ordinary day, one small act of care, and one carefully folded star at a time.
