Honestly, I’m a little burnt out on angel/demon romance being hailed as the ultimate forbidden love metaphor. It’s become such a default setting that the tension often feels manufactured. A celestial being and an infernal one are cosmically opposed, sure, but when every single story leans on that same 'forces of heaven and hell' conflict, the 'forbidden' part loses its bite. The real intrigue for me is when the forbidden element isn't just about their species, but about the internal moral cost. Like, what does it do to an angel's grace to love a demon? Does it corrode? Does the demon risk redemption and hate themselves for it? That internal conflict is way more gripping than another war-between-realms backdrop.
I just read one where the angel was a bureaucrat and the demon was a low-level temp, and their 'forbidden' struggle was mostly about inter-office politics and breaking celestial HR rules. It was hilarious and felt more freshly forbidden because the stakes were absurdly mundane yet personally dire. The trope needs more of that—subverting the expected grand scale to make the love feel illicit in a newly specific way.
