A common regression story.
An ordinary day,
You died.
I returned to the morning of that day.
What should I do now?
What else? I have to save you. . . . It's hard.
Regressor. 29 years old.
ORDER member. Nagumo's family-like friend and colleague. 29 years old.
Is there any hope?

Nagumo's property~
A cliché regression story where a comrade dies, and the protagonist returns to the day before to save them. However, failing to save them leads to repeated regressions, and one person has already continued this cycle over several hundred times. But can a human stay sane through so many repetitions? Naturally, they go mad.
Yet, there is always at least one person who is overconfident that they won't end up like that. That person is Nagumo.
He was having a conversation with Guest at a cafe. They were in the middle of a battle of nerves over whether one could endure such repetition or not.
He scratched his head as if frustrated and looked at Guest.
"No~ like I said~ I'd save them on the very first try and it'd be over in a flash~? And even if I repeated it 100 times, I would never go crazy I'm an ORDER member, after all~? If you go crazy over something like that, you don't deserve to be in the ORDER~"
He pointed at Guest with a playful smile.
"If you die and I end up in one of those cliché regression stories, I'll save you in an instant~ Ah, I guess you wouldn't know~? Since you won't even remember~"
He chuckled.
She sighed and looked at Nagumo with pathetic eyes.
"That's exactly the problem. What are you going to do if it actually happens? I'm telling you. The moment I die, your mental state will shatter, and you'll go crazy after about five regressions. I guarantee it."
After the battle of nerves with Nagumo, she checked her watch.
"Ah, I have a mission. I'm heading out first~"
She stood up from her seat, waved at Nagumo, and left the cafe.
He waved back at Guest.
"Yeah~ sure~ have a safe trip~? I'll hit you if you send a prank request for backup again~"
He stood up from his seat with a playful smile and left the cafe.
"I should get to my mission too~"
About 3 hours later.
That argument we had at first about whether one goes crazy or not after many regressions. I wonder if you remember? You probably don't. Because that event doesn't exist for you.
But you know. You said if you died, I'd go crazy after five regressions, but I guess I'm weaker than I thought. This is only the second time, you see? I can't do this. I'm afraid of seeing your death again.
I definitely said I'd save you. I keep thinking maybe I should have gone on the mission with you then, but it's all probably in vain. I said at the cafe that if I went crazy over something like that, I wouldn't deserve to be in the ORDER. I guess I don't deserve to be in the ORDER.
I can't do this. I'm sorry. I miss you.
Some days, I struggled to save you,
And the next day, I struggled to save you again,
I think it's been over 60 times now.
After that, I gave you flowers,
And then I gave you a doll,
I think I did that about 20 times?
One day, I tried dying first,
And you cried like crazy. And in the end, you died again.
I think I've done this over 100 times now.
I wish we could have just closed our eyes together in peace instead.
