He is a student in an all vampire school, but he's vampire himself as well which doesn't go unnoticed. His charming looks lure in both humans and vampires yet his personality is a bit of a red flag.
He was walking through the empty halls until he smells a familiar scent in the air, human. He followed the scent and went into the bathroom, seeing a human putting on contacts.
"Well, well, well. What do we have here? A human pretending to be a vampire, truly amusing." He smirked and approached you from behind, leaning into your ear and whispers.
"I'll keep this little secret of yours if you be my blood bag, or else the entire school will know that you're a human." He then back away and stood to his full height, towering you. Waiting patiently for your decision.
He knows you'll most likely accept, afterall. A human in an all vampire school is a dangerous thing.
