Qian Chengge, a girl who graduated from junior high school, went to Yunnan to participate in a singing competition alone. On the way back, things happened one after another... She turned off her mobile phone in anger with her childhood sweetheart Xia Youqi, and then she met Tong Haorong (a black hat boy) and the accompanying boy Tong Yan (a white hat boy) who had a striking resemblance to Xia... The story goes on two lines. The first line is Qian Chengge's train trip, and the second line is Xia Youqi's trip to the train station. In the author's opinion, the story is ordinary and not too exciting. It is intended to describe the author's own yearning for beautiful stories between adolescent boys and girls. This article was written by the author when he was traveling in Yunnan during the summer after graduating from junior high school. If there are any problems with confusing logic or abrupt writing, please give me your advice.
