Sometimes the clone story is that other persons like the clone better and then the original one tries to destroy the clone, sometimes they use a clone to help them, but at the end they fight each other who should be the original one. Many are similar, but yours is a original clone story. Instead of trying to fight each other to be the original one, you made them understand each other and as the story says they should have been twins, but she died as a fetus.

SO YEAH! This is the difference.
