This is a time-travel story in which both, Sasuke and Naruto travel to the past together. There is plot in this story, but it will be mostly focus on feelings, relationships, and characters' development instead of action. I hope you enjoy it!

PS: Naruto doesn't belong to me. I'd cut my veins before writing that horrible ending!

PS2: I'm editing this story. Bubbusaja has offered to beta the first four chapters for me, while I and my other betas are still working in the next chapter. She has done a wonderful job, and she worked so fast! I don't know how to thank her. Chapter 1-3 are edited now. I'm also gointo to change a little bit the structure of a couple of chapters that I think fit better together.

PS3: Deamiel has agreed to beta this story again from the beggining. She (I do hope it's a she, I'll have to ask her next time I PM her) is a marvel. I'm going to start my Master next year, and she is done a fantastic job in finding all those little mistakes that scape me, and that will probaly lower my grades from an A to a B. So Thank You So Much for your help, and I hope you can keep helping me in the future.

I hope, from now on, everybody can read this story without been distracted by all the mistakes I make. Thank you for your amazing help, Babbusaja.

PROLOGUE

Land of Waves. Team 7, S-rank mission.

Kakashi watched over the two sleeping bodies of his students with worry. The battle on the bridge had taken a deep toll on both of them, deeper than he had expected. Nobody could deny that the mission had been a success. Gatō was killed by his employee's own hands, and in the process so were Haku and Zabuza, though Kakashi was having a hard time trying to feel any sort of joy or relief on the account of their deaths.

However, Kakashi was a ninja. He knew that there was always a heavy price to pay for peace and he was intimately familiar with the sorrow of loss. The death of those two, as regrettable as it was, was still an acceptable payment for a greater goal. There were no more obstacles left to prevent Tazuna from building his bridge and The Land of Waves would soon walk into a new era of prosperity as a result.

And yet, despite of that, it was difficult to feel victorious at all. It seemed like Kakashi still was, despite his best efforts, a sentimental fool. And all this success would matter little to him unless his two most promising students woke up soon.

"Kakashi-sensei?"

Kakashi turned his only visible eye to look at his third student. She was his responsibility too, this shinobi girl, who was not more than a child in all the ways her teammates were not: innocent and untouched by loss.

"They will wake up soon", he lied to her smoothly.

In truth, he had no idea if they would wake up. By all accounts, they should be awake already. "That's what you said yesterday. And the day before." Sakura's voice was weak and tired, barely a whisper. The girl was seconds away from crying.

Kakashi clenched his fists for a second and then forced himself to relax. This wasn't Sakura's fault. If anything, it was his fault. He was the one who decided to take the mission and brought his pupils along despite knowing the risk of going against a class A criminal, let alone two. Sakura was their teammate, and she was obviously very shaken and dead with worry about them.

"Chakra exhaustion is different for everybody. And this was Naruto and Sasuke's first real battle. Their bodies need time to rest and recuperate, that's all," he explained, trying to be reassuring. He tried not to think it was his sensei's son laying in that bed, cold and still. Tried not to think about Minato at all.

"Come on." He put a hand on Sakura's shoulder, guiding her towards the door. "It's late and we must rest. I'm sure they'll be awake by tomorrow."
