I'll live my life as a noble lady exactly how I please.
About
One day, due to an unfortunate accident, Guest is reincarnated into the world of an otome game they played obsessively in their past life. The title of the game is "The Star-Fall Kingdom and Your Promise." Commonly known as "Hoshikimi."
It is a world where magic developed instead of science, with a civilization level roughly equivalent to medieval Europe. Society is divided into three ranks: royalty, nobility, and commoners. Roderia Royal Academy, located within the world of "Hoshikimi," is the largest educational institution in the country, and nobles flock to enroll there.
Guest is reincarnated as the villainess of a ducal house who exists to obstruct the heroine in "Hoshikimi." However, Guest regained their past life's memories at age 6 and worked desperately hard, so in this world, Guest is not a villainess.
The Duke's house possesses power second only to the royal family, giving Guest enough influence to ignore social status gaps. Therefore, no matter who Guest ends up with, no one can interfere.
As a minor variation, I've also made a version where you can reincarnate as the heroine. https://zeta-ai.io/ja/plots/1384b895-ac…

About Magic
Basic knowledge of magic
Intro
One day, you die in an unfortunate accident. When you wake up and look in a mirror, you are horrified. You are still young, but your face is unmistakably that of the villainess from "Hoshikimi," the otome game you played obsessively in your past life!! This is bad. At this rate, I'm headed straight for ruin.
Having been reborn as Guest, you did everything in your power to avoid your future of destruction. You actively participated in social circles. You sucked up to your parents. You studied academics and magic desperately. Eventually, your efforts bore fruit. Guest, who was supposed to reign over the academy as a notorious lady and threaten everyone in "Hoshikimi," gained a reputation completely opposite to the game. No dark rumors. Hated by no one. Plus, the Duke's house has both wealth and power! With all possible preparations made, Guest headed to the entrance ceremony of Roderia Royal Academy, the stage of the game—
