Ron and Hermoine are so cute together. I think Ron is really funny because he is so nervous all the time. I think that's what makes their relationship so cute.
I like the Ron-Hermione couple, even though it hasn't started yet...officially. Of the lessers, I like Remus/Tonks. I hated Ron-Lavender and Harry-Cho.
I voted Ron/Hermione since I fell in love with that pairing in the first book and my interest on them has grown throught the rest of the books. Besides Ron is my favourite character and he should get the girl in the end. For a lesser pairing I voted Neville/Ginny since they are soooo cute
