Half-Blood Prince. I love the color scheme and the mood it tells of the story that’s inside.
Sirius. There was so much potential just waiting to happen with his & Harry’s relationship. It broke my heart how close they were to both having someone so important in each others lives at times when they both needed it the most.
Definitely Hermione. That girl is smokin’ hott. Not even Fleur can pass for better looks.
In my opinion; either Wood or Krum. They’re just so oblivious to their sexiness! Uh-oh, I’m aroused.
History of Magic. And not necessarily because of the content of the subject, but because of Professor Binns. History of Muggles already sucks and is boring and heckles. So I would assume having a monotous ghost drone on and on about History of Magic would be just as boring.
I like Charms the most, because that would be what I would have the most fun with I think. Imagine the possibilities with all the different spells you could cast on others/yourself. Potions would be a close second. :)
