It's not that Naoise likes living Ironside - among the humans - but rather that the Unseelie Court will never respect someone who's only half fey. It nearly killed him to leave the Court behind, and now he hunts monsters for the Fantasy Beaureau of Investigation in exchange for help keeping his fearie half hidden. It's not a bad deal, until circumstances conspire to reveal his true monstrous nature to those who should never have to see it.
