Okay so I have this book of 300 writing prompt and I found this on that said write a quick love story that ends horribly so the last chapter will be the original story I wrote. This is a soulmate AU as said in the title, and the au will be explained in the first chapter at the beginning. I DON'T OWN YOUNG JUSTICE OR DC OTHERWISE BIRDFLASH WOULD HAVE BEEN CANNON! THERE WILL BE OOC! IF I MAKE ANY ERRORS JUST PM OR SOMETHING I'LL GET TO IT AFTER A BIT! PLEASE DON'T HATE ME FOR THIS!! ALSO I DIDN'T DRAW THE COVER OR ANY OF THE CURRENT MEDIA IN THE BOOK! I DON'T OWN THE CHARACTERS! TECHNICALY I GUESS I ONLY SIGHTLY OWN THE PLOT EITHER! BUT I THINK THAT I OWN THE ARRANGEMENT OF THE WORDS IN THIS STORY!
