Yes! I have always wanted to try letting my characters dictate their story, but I'm scared that one day they don't know what happen to them, and I don't know what happen to them, and their stories never resolved--That is why, I always plot my story first.
So, it is quite a new experience for me, to let them fully dictate what they want and what they wish for, and setting myself as merely a narrator to tell the world of their story. In the end, my wording and sentences weren't the best, but I definitely enjoy letting them take the wheel for once.
They sound interesting! I can see why you love them. They have their own flaw that makes them humane. I imagine you'd really be proud to see their character development and them overcoming the obstacle in front of them!
