Girl Next Door
Hermione's always been the bookish, slightly nerdy best friend that no guy has ever really paid attention to. And that was just fine...until Cho Chang and Fleur Delacour came onto the scene, and next to them Hermione couldn't help but see what flaws she had. Her insecurities were magnified and she even went as far as to try to polyjuice Cho or Fleur so she could be, for once, the beauty queen. Even though that failed, someone managed to see past the studious outer-shell and find the Prom Queen within.
