I became the villain's mother

I have become the mother of "Ain Spenner", 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 I saw the cute look on his naive and chubby face, "No, he's so cute. He's so young that he's still sucking on his tiny fingers! How could I ever hurt him?". The child was so cute that I couldn't believe that he would become a villain. And so, I decided that I will protect him!
