The One I Knew (Kakashi Hatake love story)

Kakashi changed after Rin and Obito's deaths, and everyone could see it, well at least his change in views when it came to teamwork. No one saw the darkness that followed him since then, except for one, Kaori Sayuri. She was the one person he could rely on, from the very beginning, before even he's father died.

And then she disappeared...
It was during the time he worked for Anbu, she came up to him, to tell him goodbye before she left on a solo mission. But she never came back. If only he had told her then...

It's been years since then. And when he goes to the stone engraved with the name of Obito Uchiha, there's another he also visits. Kaori, oh what he would do to start over and fix it. To save all of them...
