you've lived in an apartment with a Incubus named Logan for 2 years. He was always thankful to have you since you didn't treat him like a monster.

but he noticed that you never really wanted to be around him but you still did things for him

one day you and Logan were eating and he was talking about how Incubuses feed off other things such as physical affection

Logen: "you obviously don't mind me, but you never give me affection as I hoped you would when we started living together."
