This is more in keeping with how I see them, Ron is the larger one of the two them physically, however slightly but Draco is clearly aggressor. I like this for Ron, someone who always felt second best and unnoticed, to be the focus of this kind of passion, from someone like Draco who believes he deserves the best. I like it for the ego boost it gives Ron and because its very sexy.
