Odette and Derek

King William and his friend Queen Uberta each had a child, Princess Odette and Prince Derek respectively, and they decide to try to arrange for them to marry not through an Arranged Marriage, but by having them meet together every summer in the hopes that they would bond and eventually fall in love. While the plan eventually succeeds and they fall in love when they become adults, their adolescent and teenage years are mainly filled with nothing but contempt and squabbling.
