Help! I forgot the name of the story i was reading

In the story it allowed you to design the girl main character, her step mom, her dad, her best friend and the boy main character, his mom, and his brother.

The story started off as the girl not wanting to go to the party, however her dad forced her to. She was talking with some other girls, then gets noticed by the this boy and his brother. And the boy wants to get her so he goes off talking to her father or somthing. The girl in the other hand got bored of the party, goes outside? And startes to dance herself. Her best friend notices her and talkes to her. And the girl and boy (and their family + the girl’s best friend) appeared to be wealty/rich.

This is all i remember… Please help me finding this story
