Infinite Blue and Evergreen (слэш)

'Kakashi had been in a million fights, had broken almost every bone, been stabbed through, tortured, eviscerated. Nothing in the world ever compared to the pain of watching Gai’s life drain out of his eyes after he opened the Gate of Death. At one point, Kakashi wished he could just go numb, but the sweet relief of nothingness never came. He had to live every day with the anguish knowing that Gai was gone, and he had done nothing to stop it.'
Kakashi sacrifices everything to take a one-way trip, with no idea when and where he will resurface. Now 5 years in the past, he is going to fix his mistakes, make some better choices, and finally tell the love of his life exactly how he's always felt. The only problem is that the war is still on the horizon, and Kakashi knows too much to sit idly by and play house when he knows that Gai will still open the inner gates if he doesn't change some things.
A story about an infinite blue copy-ninja and what he's willing to do to save the evergreen beast of Konoha. Including Team 7, Team Gai, some new help, and a lot of love with a side of angst.
