That snowy night, Shen Zhiyao returned the painting book to Su Ye and said, "We will never see each other again." Five years later, when she returned from transferring schools, he still put hot chocolate on the winter desk, but never asked her why she left. The picture book disappeared, her mother was critically ill, and her former friends turned against each other. She thought she was living in repentance, but she didn't know that Su Ye's tenderness had already carried her through the whole winter in silence. What really tore everything apart was Lin Tang's words, "It snowed that day, it was no accident."
