I've obviously never "actually" broken a girl either, since I'm not in prison.But Arael does act differently around me than anyone else. Maybe I've "broken" her more than I know, because god knows 3 years ago I never would have imagined her capable of acting like this.
However, the point stands as I said earlier... nothing is better than taking a girl, strong willed and arrogent, and breaking her until she can be shaped into whatever you want her to be, and she knows what you've done to her, and hates you for it.
