Kairi would smile at Sora but Naminé knew, she knew without a doubt, that Sora saw it was her smiling at him and when he smiled back she knew it was for her. And every embrace was for her, it was the plainest fact.
Naminé knew that when Sora's lips pressed against on Kairi's that they were his lips on hers. He would toy with her red, red hair and whisper shyly that he loved her and Naminé would reply just as shyly that she loved him to and meant it fervently.
When she lay on the beach all alone, making charms with Thalassa shells (Sora had kept her lucky charm) and Sora ran up to her shouting "Kairi!" she forgave him. He didn't need to remember her name because all that mattered was that he was smiling, holding, kissing her.
When the Sora and she lay entangled on the beach, naked and caressing each whimper and moan he made for her. He called her name.
"Kairi!" And she kissed him silent.

Wouldn't you go insane, not existing? Wouldn't you eventually merge with the other personality? That was the driving idea behind this fic.
