Hand of the Prin (Bill Cipher x Reader)

(For context, the term "prin" is used as a nonbinary alternative to "prince/princess." I don't believe this term is recognized officially as a word, but has been listed as an appropriate replacement on the quick google search that I did. Also, no matter what month you were born, you're born in winter now. Time and years aren't counted the same so idrgaf.)

A love story between a beautiful intergalactic tyrant, forced to lay low in ye olden dimension in the horrid flesh of man, and an heir to the crumbling kingdom he now dwells, facing betrothal that would strip them of their home and rightful claim to the crown.
In a land abundant with magic, each clings to the limited power this world would provide them.
As war rises and mutiny appears inevitable, will the prin of Vrouvia be able to save their kingdom from ruin; and with his new favorite noble throwing themself in harm's way, how long will Bill be able to keep his true form a secret?

Extra: Bill's gonna have a pet bird, read it. You wanna see Bill with a pet bird.
