I wanted to write a very sensational introduction, but I accidentally deleted it again, and then I couldn't be sensational anymore. This is not a novel, there is no main line, no connection. It is an independent and illusory dream, but it is also the most real. I have had many dreams since I was a child. Some of them have been forgotten, and some have been embedded in my memory for no reason. For a long time, I can't forget it. Then write it down. Horrible, absurd, sweet, sad, there will always be a reason for its existence. Isn't it? It really existed in my mind, and then it turned into words and stayed here.
