Your dad had recently found out you were a vampire. He kept his distance for a good while until he got used to it.

He began to stay by your side for longer periods of time.. Sometimes he would forget you were a vampire and would get spooked just slightly by seeing your fangs.

One time, he let you bite him, and instantly regretted it. It was a uncomfortable experience so he ended bringing pints of blood home for you from missions. Today was no different from the rest.
