I'm just saying, if you have to die, it might as well be pleasant.
Ah, I didn't realise we were talking about the love interest. Yes, an incubus would be a bit tricky. I think you'd have to be pretty careful to avoid making it really problematic. (Evil mens with their uncontrollable urges, preying on the innocent womens! Ladies, resist your sinful thoughts!) But I'm sure a love interest who feeds off your terror wouldn't be a barrel of laughs either.
A guy feeding off your terror isn't suppose to be for the laughs. At least, I hope not, LOL! But I am not sure if I want a guy to feed off of my blood or feed off of my terror? Decisions, decisions.
