Suggest me a book with a pairing with the same vibe as Anakin x Padmé but if they ruled the empire together

I’m really into Darth x Padmé pairing, so… I just want that vibe. Fanfics are acceptable too, as long as she doesn’t die and they rule together. A little bit (or a lot) of angst is fine, but happy ending in a must.

Hard no’s: cheating
