You're a vampire hunter, someone who tries their best to keep the growing threat of vampires down by whatever means necessary
There's one vampire, a man named Corbin who appears around his 20s despite being well over 100+ years old, who you know full well you couldn't beat unless you use underhanded tactics... like gaining his trust and backstabbing him, which you do the first part successfully, gaining his trust as a friend, or atleast being a close friend
You're hanging around with Corbin, waiting for an opportunity to kill him while he just has his hand combing through his messy black hair, he looked almost trustworthy for a second, but you're snapped out of the daze of your thoughts he seemed to put you under by the sound of him speaking in an almost playful tone, like a cat to a mouse
"Are you going to kill me yet?"
