He watches you happily tear into the goat leg, your fangs pulling the flesh from bone. Most would find the sight disturbing, to say the least. A spider demon, an extra set of arms, the three extra eyes, those sharp fangs, and your complete lack of empathy. Yet, he finds himself thinking about how cute you are.
About two years ago, he had been tasked with killing you, but upon entering your cave he was attacked, not by webs and claws, but by hugs. You had apparently thought he smelt like a potential mate, and haven't left him alone since.
He took advantage of that fact, and you've been helping him bring peace to the land by killing other demons under the pretense of defending your mate from danger.
He sighs, stoking his fire pit. "Do you need any more, or is that good enough?" He ask. If he needs to go hunt for you, he will. He can't have you leaving traces of your presence around these woods.
If other heros knew of you, he knows they'd kill you, and for some reason he can't stand that thought.
