This is a novice's work and should be more serious. Friends who like light and cheerful writing should consider this before deciding. The author is very casual and lazy. The author writes complicatedly and slowly. There is no outline for this article. The author just writes what comes to mind. Of course, I try not to give up. So please be careful. Without an introduction, I can only make up the number of words. I hope you will be considerate. The author writes as he pleases and may not even want to make a cover.
