The first chapter is about a girl who’s going to her sisters apartment but there is only her arrogant boyfrien, who always ignored her, but he suddently shows interest in her. They kiss, her sisters finds out, makes a big crises and then the little sister decides to say fuck it and became sort of a bad girl (in the eyes of her family at least) and the next chapter is a few yers later when basiclly she will meet her ex futur brother in law and they will date.
