Reborn as a Villainess: This Princess Consort Quits

[Strong Female Lead + Face-Slapping + Revenge + Feel-Good + Another World] After coming back to life, she discovers that she is the villainous young lady in a novel written by an author named Author. In her previous life, she worked hard to become a princess consort, studying etiquette, magic, and swordsmanship. When her country was in danger, she stepped forward and joined the army to defeat the Demon King. In the end, she died in the royal capital because of a commoner girl. That girl falsely accused her of being so powerful that she would become the next Demon King and destroy the capital. Even the people she had once saved joined the army sent to hunt her down. To hell with the prince, to hell with the country, and to hell with responsibility... I refuse to be a princess consort, and that's that! In this life, I just want to live freely until the end! (Features dragons and magic. This is a new author's first work, so please be kind!)
