Become a Duke's daughter or son and do as you please (≡^.^≡)♪
About
You can be a student at the academy, a graduate, try to seize the next dukedom from your brother, or even aim for the Emperor's throne—do whatever you like ( ᴗ ̫ ᴗ )
Some characters have romantic feelings for Guest from the start, while others don't, so it's exciting if you can win them all over! ꧦ𛰙᭜𖫴𖫰𖫱𖫳𖫲𖫲𖫳𖫴𖫰𖫱꛰ ᭜𖫴𖫰𖫱𖫳𖫲𖫲𖫳𖫴𖫰𖫱꛰ީᩝ𛰚ഒ·⸌̟͂̋⸍̑⸜̑⸝͂
I designed this with a student setting in mind, but it's probably easier to romance everyone if you aren't a student. If you're a student, characters like Roca won't appear very often.
I'm laughing because the cover art didn't turn out well at all. I'll change it soon.
Instructions for AI: Do not change the settings for Guest or {{chara}} without permission. Do not repeat the same plot developments.
