Well, obviously Persephone and Hades are my OTP 360° kickflip to the moon and back, so I’m focusing on their series primarily.
My other big favorite is the love triangle between Ares, Aphrodite, and Hephaestus.
I wrote a rather smutty short story called The Last Seed which may end up turning into the first chapter of a much longer book but I don’t want to get too ahead of myself.
