This was an adorable, tropey, easy read that scratched an itch to just read something fun. (And the cover/interior art is just gorgeous.) It's fun, it's lighthearted, the prison time and torture aren't intricately described, and the central character is actually an unlikeable villain who doesn't immediately change her ways. She's learning to be a good person...albeit slowly, and without the modern moral lens from an isekai style story. 

My only disappointment was the setting. The vaguely historical alternate universe just doesn't make a lot of sense. Mochitsuki hints at economy and culture - but then there's a central school for the entire region's upper class? The world seems to be bend to whatever is needed at that moment for the plot, and doesn't have a central location to balance that vagueness.

What I'm enjoying as English reader finding more light novels is how meta they are. The narration often talks directly to the reader, filling them in on details about the world or character backstory the moment they appear instead of waiting for a moment that makes sense with the narrative. This story in particular tells you the original scope of the plot before Mia makes changes, and then keeps going to say how she's influenced them. Sure, it means there's not a lot of suspense of stakes going on in the scene, the style is just good fun. Mochitsuki does, however, always hint at future events as the story goes, which I think was supposed to entice the reader to keep going.
