That startling glance in the fifth grade, when the eyes of Jiang Peiwan and transfer student Lin Jianyu met for the first time, a confused heartbeat was planted. From elementary school to high school, even if the classes were different, the ten minutes of sweet time between classes, the light touch of fingertips and the unexplained "Wait for me" weaved the purest pink bubbles of their youth. However, at the beginning of the third year of high school, Lin Jianyu disappeared from the world, and Jiang Peiwan interpreted that promise as a youthful and frivolous joke.
Ten years of dislocation. Jiang Peiwan became a "nomad" in the workplace who resigned casually and traveled alone. By chance, she learned that Lin Jianyu had become an elite doctor. The huge gap made her completely define that unforgettable love as a secret love that ended in nothing. One tired night when she was twenty-eight years old, when she returned to the downstairs of the old rented community carrying her old things in embarrassment, under the dim street lights, the familiar figure of Lin Jianyu looking up at her window like a sculpture made her freeze instantly. The reunion revealed the dust-laden truth: the drastic changes in his family that year forced him to disappear with a heavy burden on his back. The words "wait for me" were his only promise in despair, and the countless nights in his senior year of high school, where he stayed silently downstairs at her home, were the only glimmer of light left in his darkness. Crossing the gap between class reality and ten years of misunderstanding, this time, with low self-esteem and courage intertwined, can Lin Wan catch this heavy love that is ten years late?
