If I can expose the perfect prince's sins, then breaking the engagement is fine with me.

"Marquess's daughter Solim. I cannot forgive you for causing the bombing incident and assassinating the Second Prince. Our engagement is hereby dissolved." Solim, who was condemned by Beryl, the fiancée of the First Prince who is called perfect, at a night party. She knew that the true mastermind was none other than the prince himself—but the prince, who had aimed to eliminate Solim from the start, orders the knights to execute her as she attempts to resist. Then, a great magic spell explodes. Together with Reina, a dangerously powerful great mage heroine, the villainous daughter Solim launches a counterattack. "I don't care if my engagement is broken off. Don't think you can escape punishment before my very eyes—!" The curtain rises on a thrilling comeuppance play where a reincarnated noblewoman reverses everything and exposes the prince's darkness.
