When Kimmie was in High School, she pulled down Betty's スカート just to be popular. When she started working at Mode. I think that Kimmie was pretending to be nice to Betty because she could be 人気 AGAIN and also, she could be フレンズ with Amanda and Marc. But this time, Betty pulled down Kimmie's trousers. I saw when I was watching that there actualy was something on Betty's スカート though. So Kimmie maybe wasn't going to pull down Betty's skirt.
