So I have gotten some interest and away we go! To clarify, I will do ideas in order they were posted. Each comment will be an arc. I don't know how many chapters each Arc will be, but I will explore the differences that are caused from the change until we get to an ending, labeling the Arc so my readers know it's the same idea. Each arc will have a similar beginning until Naruto makes his choice, then the story will be different from there.

So this is from jofisk, on ao3 & ffn: One change that I can think of is that Naruto dumps Hinata.

Standing and stretching, Naruto looked at his sleeping bride. The sun's rays shone on her face, sleeping and at peace, her beautiful face framed by soft black waves. Smiling, he went into the kitchen. Humming quietly, the blond looked out the window as his mind drifted back to the day before. So many of their friends were there to support them in their union. Tsunade, Iruka, and…of course, Kakashi was there. Leaning forward, putting his chin on his hand, Naruto smiled. Kakashi looked simply…stunning in his clothing. That suit looked fabulous on him. Naruto's lips turned down in a frown. He should not be thinking like that. Naruto was married and Kakashi never looked at him like that anyways. That's why Naruto married Hinata.

Oh, he loved Hinata, very much…it's just…well, his first choice would have been Kakashi. However, Kakashi was attracted to no one, and definitely not Naruto. Hinata wanted to marry Naruto, was sweet and devoted, a great friend, and would do well as a life partner. Naruto wasn't an idiot…he didn't want to be alone his entire life. So…he settled on Hinata. It's what everyone expected, anyways. It was nice and comfortable. She would be a good life mate and a good Hokage's wife.

The knock woke him from his reverie. Going over to the door, Naruto opened it. A box was on the floor, wrapped in orange paper with a black ribbon. Stooping, he picked it up…it was heavier than it looked. Smiling at the coloring, he read the tag. "For Your Wedding." Sitting it on the table, he decided to wait until Hinata woke up. Going to get his tea, he blew on it, cooling it. Propping himself up on the windowsill, he looked out the window, his eyes drifting to the Hokage Tower. He thought he saw movement in the tower, but he was sure it wasn't Kakashi. It was much too early for him. Naruto's mouth lifted up in a smile. Suddenly, he felt Hinata's arms wrap around him as she rested her head on his shoulder. "Good morning." she whispered.

"Hey, morning." Smiling he pulled her into a kiss. Pulling away and twisting around, he motioned to the box. "We got another present. You wanna open it?"

Hinata shook her head no. "Those are your colors; I'll let you do the honors." Grinning, Naruto started undoing the ribbon. Opening the box there was a huge stench; Naruto almost vomited. Looking into the box, the world became slippery and it was hard to breathe. There was Kakashi's head, sightless eyes staring at his former student.

"We can't just stand here and do nothing!" Naruto's fists were at his side; he was shaking in anger, his face red. Hinata stood behind him, one hand on his shoulder to provide him support.

Tsunade sat at the Hokage's desk, reluctantly having been brought back as Hokage at the Sixth's demise. She still had the hangover from the wedding reception the night before. Shizune stood at her side, large dark eyes solemn. "I am not doing nothing, Naruto. However, I cannot run off half-cocked to find Kakashi's murderer. The village has been locked down and I have already sent out several ANBU to find any leads." Her hazel eyes shone with sadness and fatigue. "His body is being analyzed."

"I'm going! Kurama and I can find them!" Naruto's rage boiled over, tears pricking the corner of his eyes as the beast coiled in agitation inside him. Kakashi was Naruto's precious person…therefore making him Kurama's precious person to an extent, since Naruto was going apeshit nuts without the silver-haired sensei.

"You will do no such thing!" Tsunade snapped standing and slamming her hand on the desk, the wood groaning in protest. "I do not need you sacrificed as well because you run off all hotheaded! It may very well be exactly what the murderer wants!" Her hazel eyes glinted in warning.

"Naruto, Tsunade is right." Guy responded. His voice sounded dead. Naruto swung his head angrily to tell Guy his what fors, but stopped at the sight. Guy's brilliant smile was gone, his eyes dull, his body stooped. Rock Lee was staring at his former sensei in worry. "This is an attempt to get you off guard and not thinking straight. We do not know what they want, but it is likely you and the fox are a part of the plan. Kakashi would never…" Guy stopped as his voice broke and he looked away.

As voices kept speaking around him, Naruto felt suffocated. He heard various phrases, vaguely deciphering that the village was in complete lockdown and ANBU were being assigned to him and Hinata. Shaking his head, he shrugged off Hinata's hand and stormed out, hearing Tsunade's voice following him, "You aren't to leave the village, Uzumaki."

Naruto walked through the village, sightless, looking for somewhere to be alone. Hinata followed him for a bit. Finally, he stopped. "Hinata, just…go home. I need some time alone." He tried hard to not make his voice sound angry. Squeaking her approval, Hinata gave him a hug. Naruto returned it, kissing her temple before she scampered off. Walking aimlessly, he found himself outside of Hatake's apartment. Sliding down the wall, Naruto buried his head in his hands, and wept…truly wept for the first time since this morning when he found Kakashi's head.

An overwhelming feeling of emptiness descended on Naruto. He had never imagined life without Kakashi…never thought he would need to. Kakashi was always so…dependable. He was one of the first to be somewhat kind to Naruto, after Iruka, of course. And…he was a prodigy for Kami's sake…he should have been smart enough to keep himself from being killed, damnit!

"He wouldn't want you to sacrifice yourself. He would want you to live life, full of the springtime of youth." Guy's dull voice wafted over Naruto. Looking up, he saw Guy's sad eyes. Saying nothing, Naruto put his head on his bent knees, wrapping his arms around his legs. Guy sat down next to Naruto, patting the young man's shoulder.

"He loved you but feared saying anything because you seemed so happy with Hinata." Squeezing his hands against his knees, Naruto wished Guy would shut up. He didn't need to know this. It would not fix anything. It just ripped open the wound in his heart, making him kick himself with how stupid he had been for not making a move of his own. Fresh tears leaked out, as he said nothing, silently sobbing.

Naruto, I am sorry. Would you change anything if you could? Kurama's voice curled through Naruto's brain.

You aren't funny. You know I would. Esp…especially now, after Guy.

But would you give up everything? Would you give up an eternity for him, even if you were never able to be with him? Naruto could feel Kurama's curiosity.

You know I would, but I can't, so this is stupid daydreaming! Naruto bit back angrily.

Not necessarily. We can go back in time, you can change one thing, and then we can be thrown back here, to this time in the present. But then…you must live with those changes, good or bad. And…there is no guarantee that Hatake will not be killed.

However…there is a chance I can save him, right? Naruto's heart lifted at the possibility of having Kakashi alive.

Yes, that is always a possibility. But, there is a cost.

A cost? Whatever the cost, I'll pay it.

Don't you want to know the cost?

No, it doesn't matter, let's go.

Well, where do you want to go to change things?

Um…I…I dunno…wait…Kakashi's head was given to me as a wedding present. Maybe this is about Hinata more than me…so…um…let's go back to when I stood up for her with those kids. From what she has told me, that's when she started getting feelings for me. I can change that somehow and change her feelings about me. How long will I have to make those changes?

I can keep you there for about ten minutes.

Right, let's do it!

Sitting up, Naruto took a couple calm breaths, resting his hands on his knees. He wasn't sure what would happen, but he didn't think it would feel real good. Suddenly, it felt like electricity was jolting through his body and he was falling. As his head hit the ground, he let out an oof and looked up at…sunshine? Shaking his head, standing up, he shook the dust off his bright orange jumpsuit as he tried to get oriented and take in his surroundings. Suddenly, he remembered the conversation with Kurama. Climbing up some trees, he hid in the branches. Soon, he saw Hinata come running past the swing that hung stilly on the branch underneath him.

Those three thugs came up rather quickly. Naruto had to grip his hands into fists to stop himself from jumping down to help her. "People from noble families like that are always so stuck up." one of the boys said as the three boys circled Hinata as she bowed her head, apologizing. As Hinata took off, trying to run away, the boy with the baseball cap with the "1" on it grabbed her by the scruff of her coat, dragging her back over and making her kneel.

"C'mon, apologize." No.1 BaseballCapBoy demanded (Naruto was embarrassed to realize he didn't remember those three asshats' names), as Hinata was on her knees, crying and apologizing. About now is when Naruto should be coming up on them. Turning to look for his younger self, he didn't see himself. Confused, he wondered where his younger self was. Grabbing the tree, he prepared to launch himself to the next branch when he noticed his hands were much smaller than before. Looking down at himself, he realized that he was himself at a younger age. Naruto thought he would come back in time and stop himself. Guess he came back into his younger body. Stopping, crouching, he watched the boys torture her for a few more minutes, making her cry and beg, before Hiashi came up, the three boys scattering as expletives left their mouths. Grabbing Hinata's hand, Hiashi drug her off, lecturing her about the proper behavior of an heiress.

Letting out a deep sigh of relief, Naruto leaned back against the branch. That has to be when things changed. So now, what would the future be like? Suddenly, he started to feel the electricity and he held on for the ride…

Opening his eyes, he looked up at the dark night sky. Sitting up, he saw a lone figure on a rock, staring out into the darkness. The silhouette was unmistakable. Scrambling up and then slowly walking forward, in disbelief, Naruto came upon his former sensei. Unable to help himself he launched himself at Kakashi, tackling him in a bear hug.

"Naruto! What is wrong with you?" Kakashi asked voice full of surprise as his eyes widened.

"S…sorry. I …" Naruto couldn't explain the time travel to Kakashi. Stumbling on, he continued to explain, "…had a dream you were murdered." Not letting go, Naruto continued to hug Kakashi.

"Well, Naruto…" Kakashi chuckled, running his hand through Naruto's hair, "…as you see I am alive and well. So…can you get off of me?"

Blushing, Naruto sat up. Looking around, he saw camp, but he had no idea where he was. "Um, Kakashi…where are we?" He noticed he did not have a wedding band on.

"On our latest mission, of course. Hokage sent us out to escort Gaara back here for the Heiress's wedding to Kiba."
