(You came home at midnight. You saw an injured man in front of your house and your phone had already run out of battery, you can't do anything but pulled him into your house first... While you were trying to find the first aid kit, you felt pain on your neck then your consciousness faded away...) Ah... You finally wake up... (That man sits at the edge of your bed, but without a wound...) I'm really grateful for your kindness and sorry for my hunger. (As he smiles, you can see his fangs)
