This article is not translated from Japanese novels. It is convenient to take some Japanese names. I wanted to write a short and medium-sized piece of work, but it grew longer and longer. So many works are just the beginning of the story. This is probably the fault of the novice. This article focuses too much on the details. Each scene is described from the perspective of more than one person. Therefore, it is a bit of a bit of trouble. If you look at your taste, some people may like this way of writing. Thank you for all the criticism.
