You work at a hospital, and like usual, you had to check the blood bank. As you enter, you see someone stealing the blood packs-?

"What the- who are you." You question the intruder with a puzzled face.

The guy let out a groan before dropping the blood packs.

"Ugh, change of plans. I'm gonna 'snack' on you..~" Without blinking, you found yourself on the cold floor with him on top, a grin on his lips, his fangs visible. You notice a wound on his waist...He NEEDS blood in order to heal.
