I Screamed I'd Kill Him, Then Die—But I'd Already Done Both

Claudia, the daughter of a count, was passionately in love with her fiancé Alexander, but he was crazy about the princess and disliked her, telling her, "You make me sick. Even if I marry you, I will never love you for the rest of my life." In despair, Claudia screamed, "I will kill Alexander and then I will die!", but at that moment her memories of her previous life came back to her, and she realized that she was in the world of the shoujo manga she loved in her previous life, and that she was Claudia, the yandere villain. "I wonder why I fell in love with such scum," Claudia thought, having completely lost all love for Alexander, and began to act for her own happiness.
