Hm.

As long as the dragon is in a child form.. I can't ship him with anyone. And honestly I don't see much good coming from Suu and him. He is a supernatural being. Dragons are possessive and obviously feeding from him will eventually kill him.

I rather have Suu with the Prince, atleast I can see potential character growth on both sides. Yet it's possible for the dragon to have character growth, but if he did, he may bring the rain to help all that need it. Oh well.
