>>91808148>Have her go from seeing him as a cute demon prince to seeing him as a dick, while he goes from seeing her as a weakling to actually being impressed by her, seems about right.
Then you would literally be turning MonStar back into Star.
I've always figured MonStar is supposed to be the polar opposite of Star. A good princess who doesn't go on adventures and instead spends her time in the castle with her parents learning about the kingdom. Or something similar to that.
And it's not just Tom that's fucked over MonStar. Part of the AU is that life in general keeps fucking over MonStar.
Between the uneasy Monster and Mewnian relationship in Mewni and the negative disposition on her looks back on Earth.
She gets her source of comfort when she meets Marco on Earth. Marco being the only one sympathetic enough and forced to live with her long enough to eventually begin tolerating and even befriending her.
While still trying to keep it a secret from all of his school friends and acquaintances for fear of being forever nicknamed "Monster lover" of course.
