Romione

Ron and Hermione are the perfect HP couple. 

They show us that true love has to be innocent, sincere and simple. That's what makes love so beautiful and hard to find. The fact that this simple act of wishing good luck has so much impact on Ron so he needs some time to realize what happened, is so cute and it showed me that sometimes, the biggest and most expensive present isn't the best, sometimes, something small and free means more to us.
