Why does it say original creator of just 'Forever and Ever' and not 'One and Only'? They're from the same novel.
Well, technically the original novel is primarily focused on the Forever and Ever storyline, while the One and Only storyline is fairly short and not as detailed. The dramatization of it pulled the two storylines apart and they expanded the historical plot. There may also be like..production things in it, but thats rrly the biggest thing about it.
