I need some story ideas?

I did a question before about ideas for a book and someone gave me part of the answer i was looking for so ive out some of my own ideas into it and this is what the story is about. it's about a girl from new york city with a famous dad moving to a new school and she meets a bunch of girls who have famous parents too and who r rich and wear like designer brands and she has a crush on a dude who some other very popular (but not as popular) girl likes him too. the clique share a secret with the new girl that one of the girls father isnt really rich therefore she's just a normal girl and the not as popular girl tries to kind of hold it against them like kind of blackmail the group into making the guy like her instead of the new girl and they have to try and find a way to stop her. do u like it? if not can u give me some ideas on how to work on it? even if u do like it give me some ideas
