Lin Wanxing was admitted to the experimental class of Xinghai City No. 1 Middle School, and was arranged by the teacher to sit at the same table with Jiang Che, the top grader. When they met for the first time, Jiang Che's aloofness made Lin Wanxing find it difficult to approach, and the two had little communication. Lin Wanxing discovered that there was an unused piano classroom in the school's art building, and secretly went to play the piano every day after school. By chance, she forgot to bring the piano sheet. Jiang Che passed by and accurately told the name and author of the piece she was playing, which surprised Lin Wanxing. She suspected that Jiang Che also knew piano, but Jiang Che denied it and only said "Heard it before".
Class activities required preparation of a program. The class leader recommended Lin Wanxing to play the piano, but Lin Wanxing refused out of fear. Jiang Che heard from the side and privately handed her a note that read, "Music is used to express oneself, not to please others." Lin Wanxing's heart rippled.
