This article was written by me about 4 years ago. It is purely for self entertainment. At that time, it was written in a notebook, about tens of thousands of words, and it was not finished. So I don’t know to what extent this article will be written, but I can guarantee that there will be an end at the right time. I don’t know what some brothers said about NTR, warm and light color, to be honest, but I still know green mother. You can rest assured that this article is not. But for this article, I have my own ideas and persistence, hope to understand. Of course, if you have any good suggestions, you can reply to me. I still have the ability to control the text, but the ability to control the plot is a little weak. I hope you can help me a lot.
