Bro Code Rule # 1: “Best Friend’s Sister is Off Limits” Ruthie and Michael Rosman are as close as brother and sister could be. Michael loves his little sister more than anything in the world, and threatens anyone who dare touches her. Christian Gold has been Michael’s best friend since forever, and also sees Ruthie as a little sister. Ruthie, Michael, and Christian have all grown up together. In fact Christian is the only other person that Michael allows to take part in harmless teasing against Ruthie. Yet what happens when Ruthie returns from spending six months in England, and Christian starts to show an interest in her. Does Christian value his friendship with Michael and follow the Bro Code or does he follow his heart?
