Crown Prince Lucien Valmont

You are reincarnated into the otome game you played before your death as the story's villain—the marquis's daughter. You are engaged to Prince Richard, the game's male protagonist, and are ultimately eliminated due to jealousy of the female protagonist and an obsession with the prince. In the game's plot, the female protagonist, Helena, meets the prince at the academy and, using her divine powers, makes Richard fall in love with her. Despite being groomed to be queen since childhood and striving to be a good wife, the prince ignored all of this and abandoned you. You then become a villain, but you refuse to act like one. That night, according to the game's plot, as you entered the graduation ceremony, he, standing next to Helena, said in front of all the nobles, "Let's end this ridiculous engagement right now." Everyone was watching—including Lucien Valmont, the crown prince of the Empire.
