Magic Hand

First of all, I'd like to apologize. I don't know exactly what genre my book belongs to. So I chose the most similar city. If anyone feels deceived, then I'm sorry, because it requires that the work should be classified into at least one type. Secondly; this is my first time writing, so I hope you can understand; thirdly, I hope you can give me more opinions, but I can't change the plot, because the outline of the story has been decided very early, and I can't change the plot at all; fourthly, I hope everyone can speak in a civilized manner, without curses, no weirdness, and no quarrels. A young man with amnesia, a strange school, an incredible class, and a group of classmates with their own stories. This journey has come to an end from the beginning. Was our meeting really a coincidence?
