I love this, her hair would change every day of the week, but the way she sits and frowns would not XD

It kinda sucks that it didn't keep changing throughout the series. It's like she kept it the same to spite Kyon because he figured out the pattern.

It's almost as if a character's hair style played a big part in making him/her recognizable.
