A/N: This one's a Modern AU in which Hector and Carmilla are not dating (yet) but know each other already. Modern humans are aware of vampires (and other supernatural beings) existing, and there are interspecies interaction laws in place similar to the ones in Monster Mususme (but in a more serious context).

"Leave her alone," Hector said, putting himself between Carmilla and the human man who'd been sexually harassing her.
Rationally he knew that as a vampire she was in no real danger, but Hector couldn't just stand there and ignore it when that was going on in front of him. He didn't know why Carmilla hadn't managed to extract herself from the situation already. Was she trying to avoid making a scene in public?
The drunk human tried to argue with him, but Hector said coldly, "She already told you no. Yet still you persist. You know that by both human and vampire law, she has the right to kill you now?"
The man suddenly looked uncertain.
"That's not-" he started to say, but Carmilla interrupted him.
"Well, that's not the way it's phrased in legal terms, but human law and vampire law are both in agreement on this point: a human who initiates or otherwise consents to sexual contact with a vampire assumes all liability for the results of such, including (but not limited to) injury, blood loss, or death."
She leaned against Hector's shoulder and bared her fangs (it was not a smile) at her former admirer, who was now slowly backing away.
"Did you... want to kill him?" Hector asked, once the drunk had stumbled away, sounding as though he regretted butting in if that were the case.
"I was trying to avoid doing that, actually," Carmilla replied. "Although I honestly don't know why I bothered."
