Fawning Over a Corpse

Dana and Fawn are a perfectly average couple; they rent an apartment together, they're going to get married when the time is right, and there is absolutely nothing wrong with Fawn. Dana knows that her dearest fiancée is perfectly fine.

...As long as she ignores Fawn's ever-growing, all-consuming hunger. But averting her gaze is starting to become more and more difficult by the moment.

Résumé

"Nothing is wrong with my deerly beloved; she's just hungry."
