Hmmmm also thinking about revolutionshipping on this fine day.
Modern AU where monsters are real and people know about them. Anzu is a werewolf. She's been repressing/managing her transformations with a variety of tranquilizers, among other drugs. But it's causing behavioral changes in her day-to-day life (she's getting more aggressive, very emotionally volatile, etc). So she and her doctor decide it would be best if she did a free-range transformation. Legally, in order for this to be done, she has to have a shift partner who is not a werewolf but just as strong as one to watch over her during her transformation.
So she goes to a local club for the things that go bump in the night to try to get herself a shift partner. Enter Atem, elder vampire, who decides he quite likes this pup. He decides to be her shift partner. Shenanigans ensue.
