This is a fictional story and has no trace of real people. This is a story that may happen around us, it is very close to us. Xiao Su, Xiao Xiong, Yu Xi, and the person I hadn't thought about, they all went through such a green time together, with the tears and laughter of ordinary people, and the pride and confusion of youth. I hope that as time goes by, many years later, not only them, but we will also have such a time worth recalling.
