The Villainess Won't Fall! ~Framed and Left at the Altar, I Will Complete My Revenge at the Very End~

"Elizabeth, I'm breaking off our engagement." At the ball after graduation, I, a duke's daughter, have my engagement broken off by the prince, my fiancé. The prince, together with his mistress, reveals one after another of my misdeeds that I have no recollection of, cornering me. This is the first humiliation I've ever experienced. That foolish prince has gotten too full of himself. Never. There's no way I would just passively accept such humiliation. And so, my revenge begins. This is a ball that will lead to the destruction of the prince and his mistress... This is a short story. *Also posted on Kakuyomu and Alpha Polis.
