Take it from me, being disowned isn't the worst they can do to you. It's bad enough, of course. But I applaud you for your courage. I admit, I was occasionally tempted to give in and just marry the girl my father had picked out for me, but... Well, I did despise her, and she'd have been more than disappointed in my performance.
I haven't been back to my home country in many years, now, and have only seen my father once in all that time. It wasn't a pleasant experience. I had no wish to speak to him after he tried to use forbidden blood magic to alter my mind and make me do what he wanted me to.
