My Own Villainess - A Doomed(?) Villainess Isekai

Torn from his own world and stuffed into the body of the villainess he'd been writing, "Amelia" must navigate a world she really should know - too bad she was never great at worldbuilding. Now stuck in a world she (maybe) created, Amy quickly finds that reality has filled in the details she failed to describe. The characters who were so flat when she wrote them now have nuance and motives. The kingdom she wrote into existence is experiencing internal strife she'd never even considered. And let's not even get into the complexities of the magic system or the infuriating demon that forced her into this situation to begin with! Oh, and then there's the fact that she's about to be arrested and executed - but surely she can come up with a way to get out of that... ...Right? Cover by thesweetwinter ~~~ What to expect: - A dense protagonist who's nevertheless trying her best - A devoted (if occasionally somewhat antagonistic) knight - A yandere maid - A long suffering heroine - Weak to strong slow-burn power progression with some real setbacks now and again - Politics, as the protagonist is demoted from being a duke's daughter and prince's fiancee to simple commoner (and yet still forced to attend school with her former peers) - Romance! With who? Even I'm not sure yet! - There's that yandere maid again
