But she arrives years too early, finding him as a weak young dragon boy instead of the terrifying monster she expected. So she takes him in and raises him herself—only for the arrogant future destroyer to become a clingy puppy who refuses to leave her side. She was supposed to raise the world's greatest destroyer. So why does he look at her like she's his entire world?
