Beautifully Wrong

Cosmo and Nation are just a brother and sister with unnatural lives. He's a strange, lonely young man and she's an ill-tempered, strong-willed young woman. They are the only people in the world who truly understand one another. Is it really all that wrong for this to happen? Will the forces of what's considered "right" and "wrong" drive them apart? Or closer together?
