Since you know so many bad boys stories maybe you can help me!! I'm looking for a book with a girl who's in love with the popular guy in school and then one day he asks her to tutor him. They are at his apartment and his older brother shows up and takes an interest in the girl. She meets his older brother and they make a deal that he will kind of date her so his brother, the guy she's in love with, will get jealous. Do you know which book I'm talking about?
