Naruto: If I ask you to kill Sasuke, you will become a succubus?

The beginning of the movie made me put all those messy thoughts behind me for a while.

But halfway through, I couldn't sit still.

The movie tells the story of a hero who is deeply in love with a heroine, but the heroine dies in an accident.

The hero was devastated and dreamed of the heroine's resurrection. Finally one day, he really traveled back to the past.

The male protagonist made many different choices from before, took a different path in life, became a winner in life, and saved the female protagonist, but the world eventually collapsed.

He kept starting over, correcting his choices again and again to keep them consistent with what he had done before the time travel, but he still kept saving the heroine, and the world still collapsed.

In the end, he realized that his choices every time could not be changed, and everything that happened in the past must happen again in order to save the world.

The heroine must die.

Some people in the cinema were already crying, but I had a lot to say that I couldn't get out.

"Why?" I couldn't help but ask Shikamaru, "On what basis? Why would the world be destroyed just because one person was saved? Is the world so fragile?"

Shikamaru said in a calm tone of analyzing information: "Because this is a tragic love story. Through this experience, the hero will face up to the departure of his lover, then cheer up and move on."

"But he traveled through time! He went back to the past! He went back to a time when nothing had happened! Why should this world be fixed? Why should his lover have to die?"

My reaction might be a bit too much. Shikamaru looked at me in surprise: "Asaro? This is just a movie. It's just set up to serve the story."

But I couldn't let it go and insisted on asking: "What does Shikamaru think about this kind of thing?"

Shikamaru was one of the people who sent me back. It would be strange if he agreed with the view that the past cannot be changed!

"This kind of thing...? If the person I like dies, then... "

"Time travel thing!"

"Excuse me," a girl in the front row turned around and interrupted our conversation with a frown, "Can you please stop talking?"

Shikamaru replied, "I'm sorry," then looked at me and whispered, "Do you still want to see Chaolu?"

I immediately pulled Shikamaru up and left: "I don't want to watch it anymore!"

For me, figuring out this question is more important than watching the movie. Besides, I don’t accept the setting that the world will be destroyed if I travel back to the past to save someone!

What's so interesting about this kind of story!

It was already afternoon when I rushed out of the cinema with Shikamaru. It was too early to go back to the welfare home, but we didn't have enough time to go somewhere else. We walked towards the river, and I asked, "What does Shikamaru think? What does Shikamaru think about time travel?"

Shikamaru said, "I have actually thought about this question."

"I want to hear it!"

Shikamaru thought about it, probably considering where to start: "I think there may be two systems. System one is that if a person goes back from the future to the past, in order to ensure that the future will not be changed, then he cannot change anything in the past."

"What if it changes?"

"If it changes, then the new past will lead to a new future. But if the future he traveled back to no longer exists, a paradox will occur. So I think the original future will not disappear, but will continue to develop along the setting of 'without him', and he will go to the new future."

I thought about it, and what this system means is that if I return from the future to the past, even if I ensure that Sasuke survives to the end and then saves Naruto, I cannot change the future world where I was born. After sending me away, they will continue to sink in despair.

And I, and only I, can go to the future that Lord Shikamaru and Orochimaru wish for.

But if that's the case, is there any meaning to my mission?

My heart sank.

Is it impossible for me to help them, to save them?

"So, what about the other system?"

"Another system is that the world may be like a game with different endings, but the real world has more endings - infinitely many. Every choice you make is fixed. No matter what you choose, there is a corresponding route in the world that leads you to different fixed endings. This is the parallel world."

"But..." I whispered, "Even with this system, it is impossible to go to the same future after changing the past, right?"

"Well, because the past has changed."

"Then why do they say in the movies that if you save one person, the world will collapse?"

"Maybe there is a crisis that can destroy the world." Shikamaru said, "For example, the world may be in danger of destruction in the future, and the only person who can save the world is the hero in the movie. However, the reason why he became that person is because of everything he experienced in the past. If he went back to the past, for example, and saved the heroine, he might not grow up to be the person who can save the world. Then when the crisis of destroying the world occurs, no one can save the world, and the world will be destroyed - this can also be regarded as changing the past and causing the world to collapse."

"That is to say... it's not that the past cannot be changed. Changing the past will only lead to a new future. However, a new future that is better for individuals may not be a better choice for the whole world, right? In order to create a savior, the savior must sacrifice himself and cannot receive help...? Isn't this very unfair?"

"In fact, you don't have to be so serious about it, because time can't flow backwards, and people can't go back to the past, so for settings like movies and novels, as long as the author can make sense of it, it's fine."

But I couldn't listen to Shikamaru's comfort, because I knew that time had gone backwards and I had returned to the past.

What is it like?

Can I save Shikamaru and the others from the future?

I whispered, "So, are the 7-year-old Shikamaru and the 17-year-old Shikamaru the same Shikamaru?"

Without waiting for his answer, I said, "It's the same person, right? Just like a seed, it will grow into a tree ten years later. So even if it goes back to the past and becomes a seed again, it will still grow into that tree, right?"

Shikamaru said, "I don't think so."

"why?"

"Because people have their own consciousness, and their thoughts are constantly changing. Maybe the same person, after experiencing different things, has completely different thoughts and behaviors at the age of 7 and 17. In that case, although they are the same person physically, they may not be the same person mentally. Compared to the body, I think the shaping of memory is the most important."

I was silent.

Shikamaru's words completely destroyed the meaning of my existence.

If I can't save the people I want to save, and the people I save won't be the ones I know, then why do I exist?

"Asaro..." Shikamaru stopped and looked at me in panic: "Why are you crying?"

I have cried in front of Iruka-sensei before, but that was because I had never cried before, so I wanted to practice crying. But this time, it was not intentional, but tears naturally welled up in my eyes.

"Isn't this unfair?" I felt myself trembling all over. "Why should I spend so much energy and make such great efforts, but nothing can be changed? Besides, if Shikamaru died, I wanted to save you. I just wanted to save you. Why should the world be destroyed for this? The world is so big, why should it collapse just because one person survived?"
