That's so much better than my theory:

Fighting over which was better... Breasts or Butts.

Ddraig arguing in favor of butts, and Albion for boobs. And the God from the Bible punished them by making sure that they always got possessors with their opposite fetish. Hence Ddraig, who loves butts gets stuck with breast lovers, and Albion vice versa.

I came up with this theory a while ago but never posted it. Thought it was just to cruel to the Two Heavenly Dragons.
