Ahh, I understand… Sometimes, it may become boring to write the same story with only a different love interest.
I don’t want to pressure you or anything, but I wanted to tell you about my idea (you can ignore me; that’s okay :) ). Perhaps Y/N could be the daughter of Hades and Persephone and Mal’s half-sister, although neither of them knows that. After Hades was imprisoned on the Isle of the Lost, Persephone was still able to visit him secretly. However, after some time, all they did was argue, so Persephone eventually stopped visiting him altogether. During one of her visits, she became pregnant but never told him.
Hades, angry, sad, and depressed, got together with Maleficent (I know that the fourth movie shows that they have been together for a long time, but let’s ignore that), and they had Mal. Afterward, Hades left them.
Everything in D1 and D2 happens as usual, but in D3, after Audrey turns evil and attacks Auradon, they need Hades’s Ember. However, they know he will never give it to them, so Ben suggests asking Y/N for help because she is Hades’s child, and so on.
Sorry, I rambled on for so long… I just love your writing style so much. Have a lovely day or night! <3
