Learning by oneself was always doable, but if there was someone willing to teach you for free then that was always a bit better than attempting the alternative. Granted, that was making the assumption that she would teach him for free. He had just figured that she would, as Dorian had set it up and she was staying under his roof.
Looking down at her, he awaited a response. He wasn't going to take no for an answer. He rarely did. Still, it was nice for some confirmation. "Is that good enough for you?"
