Note
before we begin, i want to say a couple of things; first of all, i DO NOT support JKR, that being said, i also don't own any of the characters in this fanfiction, except for Emilia Mirem, who’s an OC made up by me. And i apologize in advance for my, sometimes, not accurate English; since it's not my first language.the first few chapters will probably suck, but it will get better.thanks for reading :)
