Lin Wan, a sophomore transfer student in high school, transferred to Xingyu Middle School with her grandmother's last wish, just to hand over a yellowed letter and a tin box full of old things to senior high school student Chang Jiang Yi, the "old friend queen" whom she had never met. When they first met, Jiang Yi was flipping the pages of a book in the sunshine of the library, but Lin Wan was deliberately getting closer. From the original intention of "complete the task", she gradually fell into his gentleness, which was cold on the outside and warm on the inside. When the campus turmoil pushed the two of them to the center of public opinion, Jiang Yi's protection and preference made Lin Wan understand that her painting brush had already painted a trace of his heartbeat. What is sealed in the tin box is not only the youthful regrets of the elders, but also the code of a two-way secret love that spans time and space. Under the blue sky, the thoughts that have been silent for a long time will eventually turn into light rushing in both directions.
Purpose: Focusing on "youth secret love" and "intergenerational emotional inheritance", through the interweaving of the story lines of the two generations, it shows the sourness and purity of secret love, and the courage and responsibility of growth. It conveys the warm core of "love can transcend time and space and become the light that illuminates each other's lives", and at the same time calls on readers to cherish the silent guarding hearts around them.
