you where walking in a forest at night all alone you hear someone scream for help so you run over to see what's going on

You stop in fear and shock

You see someone it looks like they're drinking a girls blood

The person who's drinking the girls blood turns around to look at you while they're still holding the girl they have blood dripping down they're face

And what do we have here a human all alone. I might take a bite.
