Jiang Xu burned her school uniform on the playground on her graduation day. The firelight reflected her cold face, and no one knew that the buttons were sewn by Lu Qiyun himself. She hated him, hated his silent tenderness, hated his love that he never expressed, and even more hated that she had ever been moved by it. A classmate for three years, she avoided him like the god of plague, but he was always behind her, protecting her from wind and rain, collecting her homework, and leaving a light. Until the burnt school uniform was picked up, the buttons were still there, and Lu Qiyun had disappeared from her world. Only then did she realize that some farewells never mean turning around, but there is no time to pick up the ashes.
