Transmigrating: I'm Vacationing in a Small World

This is a new novel, and I'm a novice writer. It's just a novel written by someone underage who had to work at a factory. Even the bank account I used to publish it was opened at the county office, got it? Read it if you like, but if you don't, please don't leave nasty comments. The main character in this book is Severus Snape. Aside from helping Snape, our female lead also helps Petunia Vance, the Villain. In other words, she helps the female supporting character because she deeply sympathizes with her due to her troubled family background. Those who know, know. Rather than read my introduction, just go straight to the book. The story itself will do a better job of explaining things. As a beginner, I don't know how to grab the public's attention. I'm not much of a talker, and I have a word disorder and assets. I once believed that next time, if I wanted to be mentally ill, I'd get tattoos.
