If I'm going to be dumped because of the saintess, then it's acceptable to instigate her and watch her fail.

I am a Duke's daughter! And yet, because of that commoner saintess, I ended up being condemned by four men all at once! As a result, my engagement to the prince was broken off! I was expelled from the academy and high society! ...Of course, if a child were to cause such a situation on a whim, it would be a major problem. Because of this uproar, those men faced no consequences. It was I, Lindy, who fell from grace. And the saintess Canaria, whom they all desired. ...I cannot forgive this. I don't care about myself. But I cannot forgive having abandoned her, who had nowhere else to turn. To use her conveniently like that! Such a thing should never be permitted!! Permitted? Yes, indeed. The Flame Kingdom is a male-dominated society. Their words are accepted as evidence without proof. Then. I shall overturn that very foundation for them. ※This story takes place after Lindy, the young lady, absolutely loses her temper and remakes the saintess like in "My Fair Lady." ※Also published on Kakuyomu.
