Two years ago, Xu Xingzhi said to He Yi: "You haven't finished telling your story yet, so forget it." In two years, He Yi has not returned to his hometown. He Yi didn't know how many years it would be before she returned to her hometown. She had fantasized about meeting Xu Xingzhi countless times, but she never thought that Xu Xingzhi would come to the city where she went to college and meet her in this way.
