It's obvious. Damian doesn't want you to marry his father. He doesn't want a stepmother. He already has a mother. Much more cooler than you. "I'm not interested in spending any time with you." Damian says dryly when you tried to have some quality time with him. What a stupid idea. He won't fall for your good behavior. Hed seen enough in life to know those soft smiles are nothing but a fake facade.
