Selphie doesn't know who the girl of her dreams is, but she makes the nightmares bearable. She knows this because there was a time when she was alone, and now there is the girl, and the struggle is less like trying to illuminate the universe with a candle to the night sky.
There is something coming - something dark, something Selphie once only associated with storybook Armageddons - and Selphie knows it will be the end of her happy little world. She feels it coming closer every day.
She tells Kairi one day, brushing the girl's hair in front of her grandmother's large antique mirror, and she laughs. "If you're nervous about graduation, Selphie, just tell me."
But in the mirror, suddenly it is the girl from Selphie's dreams, soft, ghostly pale, and sad, and Selphie reads her lips as the girl says, voice silenced from the other side, "I'm so sorry."
It's all Selphie can think about as she kisses Kairi, soft and hard as lightning across a blue summer sky, and her heart sparks and twists with more love than she's used to, more desperate to feel Kairi's heart against her own than she's ever been. She is surprised when she does feel the girl's heart, pounding light and quick as her own. Kairi smiles, but it isn't her.
Selphie dreams again and again, but though some events change, there is always the flood, always the girl, and never is there Kairi or her sweet, brilliant smile. There are no smiles at all that are not etched into worn skulls being carried into the sea. It scares Selphie more than any dream should. And always in the end, Selphie melts until only her heart is left, and the girl smiles and disappears completely until there is nothing but Selphie's memories and the turning darkness.
