I'm not even kidding. I'm crying... seriously.

That was so beautiful. It captured Riku's unspoken feelings for Kairi PERFECTLY. Just completely and totally. And you didn't even use that many words. It was simply, really simply, perfect.

The story format is unique- I think it made the story more beautiful and sad.

Aside from spelling problems, the story is well written. I do think you should go through and fix the grammar on your title and description.

Otherwise, great job!
