Overdone idea, but I needed to write something.
Under the Faces of Friends
...
Sora liked Riku, a lot. It wasn't something profound, and the realization of such feelings did not startle the teen. Rather, after he and Riku had very literally plummeted back into the routine of life on Destiny Islands, Sora had simply greeted the feelings directly. As if friends, really, and he was okay with this. He'd always felt them, in whatever way – first acquaintances, then brothers, then more. That was how it always went, though, Sora thought. Always the same in stories about love. But one day, after a month of being back home – Sora recalled Kairi's sweetly smiling face and soft grip, on the day he had returned, and it made his heart lift – something shifted. And again, it was nothing profound.
One day, Riku had given him a look, before the school bell rang to signal the start of classes, and everything fit.
...
Riku loved Sora, very much. It wasn't something that surprised him, really, as Riku imagined he'd felt this way for quite some time. These emotions did not cause him the pain that many would think accompanied an unrequited love. Probably, he mused, because loving Sora was as far from painful as anything he'd ever experienced in his life. Sora was that baby, the one that belonged to his beautiful mother's cheery friend, the lady whose smile lit up her face. That baby became an acquaintance, then something like his brother, but that relation lasted very briefly. It instead gave way to the Them that existed today. Living on Destiny Islands, living together, the strong, silent presence of the light-haired young man and that cheery boy whose smile lit up his face.
One day, as he was waiting for an ordinary round of classes to start, he turned to look at Sora. The shorter teen looked back, and Riku thought; maybe loving Sora has never hurt because deep down, this love has never been just mine.
...
Kairi cared for her boys. Hers, because somebody had to be there for them, the same as how they had been there for her. All three of them fit, naturally, simply. For this, she was always thankful.
One day, as she was watching the tail-end of that day's sunrise in front of the school's albescent doors, she saw Riku look at Sora, and she saw Sora look back.
She gave a secret smile.
...
Sora liked Riku, a lot. So much so, that even if he spread his arms out as wide as they would go, as he had often seen Pooh do when describing to his friends how much he adored honey, the span would not be enough to adequately measure his feelings.
Riku loved Sora, in the same way he had yesterday, and the day before that, and the years before that, and he wasn't trying to be romantic – just truthful.
When Riku looked at Sora one day before classes began, Sora looked back. Something fit, and another thing was realized, and so Riku held out his hand, and Sora took hold of it.
Nothing changed, really, not profoundly. It was merely an acknowledgment, like saying hello. And that was enough.
