DEVIL IN ME| "human's make mistakes all the time, but the good ones don't run away from their problems, they deal with them". [SUPERNATURAL SEASON 13] [DISCLAIMER; I do not own supernatural or anything from the show, all rights go to the creators and owners of everything. I only own my OC and nothing else]

When Lucifer first heard of his father's newest creations, he was outraged. As if these little apes weren't bad enough, God wants him to worship them? Lucifer's always been his father's favorite, and he won't let these creatures take that from him. He would rather fall than worship those things. And fall he does, and that completely changed his view on everything. Lucifer learns of love and loss, and when he's freed from his cage, he won't let it end. *** This is an old fic based on a prompt from a Facebook fanpage, and definitely does not represent my current writing ability, so if you'd like to read something less cringey, feel free to check out literally any other fic on my page ***
