"I'm a Villainous Noble Lady and the Demon King, but After the Crown Prince Broke Our Engagement, I Decided to Reveal My True Identity"

Crown Prince: "I'm breaking off our engagement with you!" Entourage: "Bullying the heroine? Are you a demon!?" Villainess/Demon King: "Well, there's no helping it if I've been found out!" Heroine: "Your Majesty the Demon King!?" Crown Prince and others: "Huh?" ＊＊＊ This is a variation of the engagement-breaking genre. When I couldn't use my computer, I read a lot of engagement-breaking stories, and I became eager to write one myself, so I ended up doing this. This is one of many fantasies I came up with. I hope you enjoy it even a little. I'm also publishing this elsewhere.
