I, Yunxi, am 19 years old. I don't have a surname, and I don't know who my biological parents are. I was raised carefully by my adoptive father and adoptive mother, but I lost everything within a few days. My adoptive father and adoptive mother passed away one after another. I only remember that the unfamiliar word Beijing vaguely appeared in my mind. When I lost everything, I thought of this and wanted to compose the most beautiful music in my life for myself.
