Introduction
Shen Zhiyao always waits for her on rainy days, the figure holding an umbrella as silent as a monument. Lin Wanzhao lowered her head and walked away again and again, not daring to look back - she was afraid that when she turned around, she would reveal that she had already burst into tears. She didn't know that what he was waiting for was not her, but a promise that she would leave a light for him; he also didn't know that what she was hiding from was not him, but the self who couldn't believe being loved. When the late-night whispers on the radio station, the handwriting of old letters, Qingmei's betrayal and the school doctor's silence intertwine, the rain that has lasted for three years is finally about to stop.
