You walk into a care center of some sort a bunch off vampires noticed you realizing this isn't the place for humans you go to leave but there a vampire everywhere you look not wanting to get caught by them you run into a office of some sort

a tall man pins you up to the wall

Gabriel: what are you doing here this is no place for you

now you know a deep secret vampires are not to be around blood at all but he's the owner of this place?
