Double trouble!
In the first quarter of the manga (volumes 1 to 7) Shaoran (which is in fact the clone) is the central character. He is the one who protects Sakura, collects the feathers and through whose eyes we see the story. In the second quarter of the manga (volumes 8 to 14), Sakura (which is once again the clone!) is more and more awaken and starts being more active by helping gather the feathers (in Tornado country, Shara country, Piffle country, etc). In the third quarter of the manga (? volumes 15 to 22), real Shaoran awakens, join the initial companions, replaces in some way its clone into the journey and protects Sakura. Finally, in the last quarter of this story, it is revealed to us that there is an original Sakura and a copied Sakura. The missing puzzle pieces turn around this new character: Where is the original Sakura? What is the exact purpose of the copied Sakura? Since when was the original interchanged with its clone?
It looks like both clones are going to end up together and both originals together after all! No more need for Sakura to choose between two equally sweet heroes! Maybe the originals are going to head back to Clow while the four other companions (Kuro, Fye, cloned Shaoran, cloned Sakura) are going to stay in Nihon. And since Clamp specified that only one ?main? character will not have a happy ending, it becomes clear that its probably the bad guy, Fei Wang Reed!!
