this is my first fanfiction then ever making so please bear with me. so this is going to be a reader insert. but the reader is as the title says Dabi's twin sibling and your character which is the reader also known as y/n is 5 minutes older. one more thing I'm going to add about your reader in the description because I don't want to add too much is that Dabi doesn't know that they're twins the mangas. Okay this is going to turn into a hawks x reader at some point
