I wish she would just let itsuki go. After what he did to her, why does she hold onto this justice thought tied to him. Yeah he saved you, and then threw you away as soon as he didn't need you anymore. She doesn't have to fall in love with naofumi, it just doesn't make sense.
It's okay to be forgiving to a certain point, but not when the person murdered your father and you don't even know if what he said is true or not. I don't like where this is going.
