I originally wanted to write it as a time-travel story, but since it is the first one, it seems to have nothing to do with time-travel. This story is just an introduction. Let me explain in advance that I am very sensitive. If you have any good suggestions, just write them down and forget about them. I have always liked people to praise me since I was a child, and don't press too hard to write. Good articles cannot be written by urging. Even if it is only 500 words, you need to carefully consider it before writing. So don't rush me. Although I am slow, I am writing.
