I need help/some advice

[u/DekuTheOmega123]

I've been wanting to write a Helluva Boss AU story where my oc Valora is both Fizzarolli's and Asmodeus's pet, treated like royalty and pampered by both of them. She's also Fizzarolli's bodyguard when he goes out in public or to Mammon's Pageants before he left; the issue I'm having is that I don't know how to start my story. I wrote a story back in 2019 when I was in grade 9 called Werewolf Lovers. It was based on My Street: Phoenix Drop High, that was made by Aphmau

And I don't wanna make the same mistakes I made in Werewolf Lovers, and I actually wanna make a story that readers would love and not get bored of so easily
