Comments of chapter undefined of Master's Untamed Wife

I wonder if she would let go of Justin if his father get to know one day that he has a son and would come to take him back. Would she not let go of it? I mean there's a line between biological and adopted. So even if she doesn't want to give his son she still has to because its not hers to begin with. I wonder if she would marry him or maybe come to an agreement that she could still see Justin.
