Yu yuaner, an ordinary girl, has always been the humble one in the crowd. From primary school to junior high school to senior high school, until she went to college, she realized what it was like to like a person for the first time, and then began to change. She is like countless you and countless me. Although she is insignificant, she is still trying to shine. You always say that growing up is far away, but in a blink of an eye, you and I will go our separate ways. The world is so big. Once separated, it will be forever.
