I Became the Villain's Mother

I have become the mother of “Einspanner”, the antagonist of a novel. I was supposed to be a bad stepmother who abused him as a child and was killed by him when he became an adult. But, when I saw the cute look on his naive and chubby face, “No, he’s so cute. He’s so young that he looks like still sucking on his tiny fingers! How could I ever hurt him?” The child is so cute that I can’t believe that he would become a villain. And so, I decided. I will protect him! This way, he will protect me too!
