There was a shojo manga I was reading about a year ago and I can't seem to find it anywhere (mainly because I don't remember the title ><).
The story was about this nerdy girl with glasses and she didn't exactly get along with her classmates. Her dream was to be popular and she couldn't do it at her school because something embarrassing happened to her - they all saw her underwear (I think?). So she ditches the glasses and gets contacts and works her butt off to become this attractive girl. She transfers to a different school outside the area I think. She really wants to be popular in this school.
Sorry, that's all I can remember.
Thank you very much for your time! ^_^
