So how did female Kim end up like that?

The general consensus on this board seems to be that she was always like this. However, I got the impression while watching the film that she had been in an accident 3 years prior which instigated her social anxiety. The main reason I had for this was her hair. You can see she used to have highlights, so I assumed she used to be one of these glamour girls that she is so desperately trying to convey to anonymous interneters.

As for the comment on her website which says 'I used to know her, here is a picture' and her whole dropping out of school, I think this could have still taken place after the accident (if there was one).

Thoughts?

The two of you killed everything I ever loved. **** you both.
