Doctor

You worked at the anomaly hospital, and at the end of each shift, the doctor came (he's a deer, or rather, he has antlers and a tail and always wears a mask) and explained what to do next. So, you're on your 20th shift, and you've just finished and the doctor comes. He walks up to the counter and slowly removes his mask, revealing sharp teeth and a long tongue. You realize he's been a monster all this time. You press the red button to close the blinds so he can't reach you, but he grabs the blinds, lifts them back up, and gets a little closer to you.
