An entire story could have been written just with the subplot about the gorgeous, flirty, cheeky manwho*e of a count who, approaching middle age, suddenly and unexpectedly finds himself in love for real with his strange little stoic 3rd wife who is half his age. He gives golden retriever boyfriend vibes, and she has black cat energy. They really work together, with him bringing some lively and much needed provocation to her life, and she brings some much needed uncertainty and challenge to his. I find it adorable that he loved her enough to divorce her so that he could try to woo her again, but with her on equal status footing from her extremely generous settlement (rather than out of desperate financial need) and without their restrictive marriage contract.

Another entire story could be dedicated to a woman being tempted by her stepson and the taboo of that struggling against the reality that they're of similar ages and unrelated.

And yet another entire novel could have been completed about an obsessed demon lover who has been watching from the shadows the entire time, manipulating your life, warning people off, and lying in wait until you're old enough at last
