my best guess would be Pocahontas. i say this because she was first with Jhon Smith, but then in the sekunde movie she becomes found with and ends up with Jhon Rolfe. just like D&G because gwen was with trent but then she moved on and is in upendo with duncan. perfect sense i think. its not all so much the intense drama but ya the story line fits :D and it also works the other way with duncan. (ignore the genders lol) he was first with courtney but then fell in upendo with gwen. so there u have it and i hope it helps! ^_^
