Fragmentary descriptions mostly focus on the description of character dialogue, giving people a sense of picture and greater space for imagination and creation. The character's personality traits must be determined by the viewer. While writing this novel, the shadow of one person kept repeating in my mind, and the images of many characters were built on his basis. So I want to say that I would like to write this article to commemorate the time that is gone forever, and also wish that all lovers in the world can finally get married!
