Er....I'm a huge harry potter fanfic fan so....yeah. My couples are Harry should be the romantic and sexy single man that takes forever to find the perfect girl. Of course, when he does she's amazing. Every man's dream.
Hermione should become the old maid cuz no guy likes her. To stuck up and know it all.
Ginny and Draco should get together and live happily ever after! Just kidding, although I do think they would make a cute couple.
Finally, Ron and Luna would be perfect together.
