Me and my dark prince/Beauty and the Beast

Lucy Hearfilia falls in love with Zeref, a dark mage, after being sold to him like a slave. She was captured by an evil wizard who toyed with her and then sold her to Zeref after Zeref appeared looking for a servant to clean his home. What will Lucy do when she realizes she has fallen for the demon who kills others, even though he does not enjoy killing, and ignores her except for telling her to clean more. My version of Beauty and the Beast: the original Disney Stockholm syndrome story Fairy Tail version.
