What will happen to Natalie when she starts singing? What does she see? Read to find out.

Hi this is my first fanfic and the description either sucks or spoils something about anything. Oops. Anyway I do not own Fairy Tail and it's characters. All Hiro Mashima's work. Don't own the song either that's Ed Sheeran's as well. Hope you enjoy. ^u^.
