I Became The Villain's Mother악당의 엄마가 되어버렸다

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. I will protect him! This way, he will protect me too! ~~~~~~~~~~~~~~~~~~~~ Ain's cute little face stared coldly at Duke Cassius, "I told you not to touch me." "Why should I listen to you?" The tension rose between the two. "You never really even liked her." the duke's eyes widened, no way... did Ain think of Roselia as more than a mother? Cassius could not believe it. "Stop scaring her, she might run away." Ain said. Ain was worried that she would leave and never come back. Duke Cassius couldn't believe it, his only son was obsessed with Roseria.
