Harry Potter and the Arrogant Jerk

The saying "opposites attract" is proven true when two very different people come together, despite their own protests. Long-ish one-shot, heavy AU. Super!Harry, sort of (it's not really relevant, just sort of there). Rated T to be safe. Basically my answer to Harry/Draco shipping: Harry/Draco's more worthwhile twin sister. Footnotes!
