I know this kind of dumps on the main theme but at the same time, when this came to me, it wouldn't leave me AT ALL, and I let some ties to it bleed in. That may not be good enough though so if you like it, then it's cannon. If there would be too many problems that would rise up from its consequences then forget you read it, please.

ALTERNATIVE ENDING:

A World of No Further Regrets

"Twenty-four hours is not enough to change an entire history or regrets. Besides, your loss is nothing compared to those around the world. We're not gods, Naruto. It's not our call."

"Sasuke, we have to, alright. I mean, what about your family!? This could be chance we need to change their path, we'll just go back before everything and—"

"I have a family."

"Sasuke..."

He looked to the Oracle, something in him radiating with reluctant defiance. "We will not take the offer. We do not need your gift."

Naruto's face shot up as he looked to Sasuke.

"What are you saying Sasuke!? Do you not realize how insane this is? You really gonna just throw this away?!

Sasuke merely stared at him for a moment and Naruto could only wince, looking down despondently. No matter what they chose, Kaguya would still come and even if they intervened then, more of the Ōtsutsuki clan would take her place threatening the world. And it was doubtful that they would have the same advantages they did then without the pain filled path.

Somehow all of this was spoken to Naruto through just Sasuke's expression. Finally, the Uchiha looked the other way, his fist clenched together tightly. "Stand up, Naruto."

And he did, his head still bowed from a great sense of loss.

The being spoke, its voice somehow sounding more monotone than it had before. "Do you accept this choice? It shan't be given again."

"I..." Naruto's hands were sweating, his heart racing. But. He closed his eyes. "Wait."

Sasuke stared at him.

Naruto swallowed. "Maybe changing death is too pivotal to the course of history. It's events. But if there's one change of no huge consequence to the world itself, as of now...It is that of a father's time." Naruto's eyes drifted the ground as he avoided Sasuke's. "My biggest regret as Hokage was letting a father walk out on his baby girl for so long."

Sasuke tensed.

"I want to go back to that day to talk to that father. And to myself as well, knowing what I know now. Before it's too late."

Sasuke smiled bitterly. "Idiot."

The figure for the first time gave an expression: a soft smile.

"May it be."
