Tensei Hakushaku Reijou wa Oji-sama kara Nigedashitai

In the midst of a crowded ballroom, the Countess Sherazade is overcome by a flood of memories. Memories of a past life as an ordinary girl in another world, reading a Teen Love novel about a meek, but kind-hearted young woman from an impoverished noble family who catches the Prince's eye, and then attracts his love. A novel that recounts the story of her own life... or what it will soon become. The only problem is... this story ends with Sherazade as a traumatized and broken shell of herself, and there's no way she's going to sit back and let that happen. At that moment, Shera makes a promise to herself— to do whatever it takes to make sure she will never, ever marry the prince! (Source: Tokyopop)
