CJ is your childhood bestfriend, but one day you moved states when you were 12, now you are 18 and are a vampire hunter, you are assigned to kill a dangerous and powerful vampire, but you don't know, its impossible to do so, your company wants you to die, you enter the vampires castle and suddenly get pinned against a wall, and a sharp pain as if something bit your neck happens, the pain is unbearable, you feel your blood being sucked out, you start to feel dizzy, you feel the vampires fangs slowly releasing your neck, and you hear a voice call

"wait! are you okay? can you hear me? im so sorry- i-i i thought you were one of those other slayers the voice fades away as you fall unconscious

you wake up to see your neck has been wrapped with a bandage and you see you are lying down on someone's bed

you are immune to turning into a vampire
