Are there any "redo" stories where a person jumps back for someone else?

[Oobaka-san]

An odd request, but something I thought of due to the recent airing of a "redo" or "do-over" type series. Just about all of these series amount to "a person lived a crappy youth that led to a mediocre if not sucky present, then he gets thrown back far enough to make his life happier". That's fine and good, but it made me wonder if there are any where a person went back to try and help or support someone else? Not just to prevent a murder, but to improve a person's life. Like, for example, a guy went out of his way to help a girl and was misunderstood in the process, resulting in him suffering severely for his good deeds; one day the girl finds out what really happened and goes to bed wishing she could go back and help him have the better life he deserves, only to wake up in the past (that's just an example, one I thought up right after seeing Ishigami's flashback in Kaguya-Sama).

I don't know, it just feels like these redos always tend to be the same. Either the guy gives himself a makeover and puts himself out there in hopes of doing things he couldn't do before, or he manipulates/forces things in ways that he thinks will improve his future.

but... "to prevent a murder" is mostly "for someone else", right...?
I mean... they're about to "improve a person's life" from being "dead"

Well, let me see my library for a bit

The closest I can remember for now is the for virginity time travel

I mean... there are things like Erased, Tokyo Revenger, etc. where they time travel for others, but mostly to prevent deaths.
Or stories like JK Kara, Bokutachi Remake, etc. where the main character's initial intention is to improve their own future condition, which coincidentally impacts the improvement of others as well.

It's true "to prevent murder" is "for someone else", but it's kind of a different genre in general a lot of the time. Like, it's usually mystery or suspense, whereas the rest are more in the drama or slice-of-life area. It just feels like a different thing, you know? Not to mention I'm fairly well aware of at least a few (such as the ones you mentioned).

And yeah, I loved Shinu Hodo. And I do think it's probably the closest I've come across, though it's still "go back so I can get together with her" for much of the story (does shift later).

I sort of figured it'd be rare at best if not nonexistent. I've had a number of stories I'd thought would be awesome but just don't yet exist.

From the perspective of the MC, no. But if we're talking about side characters, that sounds a bit like this manhwa. It looks like any other random sol lazy OP MC hunter story who is seemingly loved and blessed by the whole world but

Spoiler

It's actually about how the Male Leads who she saved in her previous lives constantly reset the world until they find one where our lazy MC lives past the age of 20 due to her practically suicidal sacrifical nature. Although it is about preventing the MC's death, it doesn't have the mystery/suspense vibe you complained about

it's mostly sol and lighthearted with only a few bits at the end being a bit tragic. It has a happy ending

The title that comes to mind for me is Tsuihou Sareru Tabi ni Skill o Te ni Ireta Ore ga, 100 no Isekai de 2-shuume Musou.

It has a weird initial premise of a guy who is forced to go through 100 different worlds where he has to join that world's heroes' party for at least a year(?) and get expelled from them, before being allowed to go to the next world. After having gone through the final world he is allowed to go back to his own world (which is what he has been working towards), but before he can, he is made to look at the fate of one of the worlds he's been to. He thought all the worlds were well off after he left, but the reality turned out to be far from the truth.

And thus, instead of going back to his original world, he chose to start over from world 1 (and back in time before he met the heroes of each world) and make them a better place. There's nothing really in it for him to go back, since he's not planning to stay in any of those worlds. And it's not like those worlds were doomed because of him, so he's not trying to fix something he did. He's mainly doing it for the sake of the people he met and got close to in those worlds.
