Bit in the short side, but I'll take it.

Please update

fantastic

Love the story so far, looking forward to seeing the interaction between Trunks and Vegeta

This looks really promising. There are little spelling mistakes floating around here and there. It certainly doesn't ruin the story, but it'd help to fix them.
So, this is just a suggestion, but I think the narrator should just call Trunks by his name instead of Mirai (Watch out for the misspelling btw. You've been calling him Miria since chapter 2.). Other characters calling him Mirai makes sense, but I feel like the narrator shouldn't do it since we're viewing the story from Trunks' point of view, and he certainly wouldn't call himself Mirai.
I'm also gonna reiterate what WolfShadow96 said; your Future Trunks is adapting to everything way too quickly and easily. He technically just lost his mother and was sent away without his consent, he should at least be going through a bit of emotional turmoil. Especially given his past. I'm not sure what you're planning for this story, but I think it'd make things more interesting if he struggled a little more with the idea of being in the past permanently.
I kinda like how Present Bulma kinda assumes he's fine and doesn't really make an effort to see things from his perspective. I mean, he literally tells her Future Bulma sent him off in chapter 2, and she doesn't question it at all and moves on. It could make for some interesting conflict (internal or/and external) in the future, whether it'd be Trunks getting frustrated that his mother isn't able to empathize with his struggles (especially if he was really close to her in his timeline), or Bulma slowly realizing she's not being as understanding or supportive as she thinks she is.
Kinda underwhelmed by Vegeta's reaction to seeing Trunks again, but I guess it's to be expected of pre-Buu Vegeta lol

I like the idea but, I feel that Trunks is a little too accepting of his situation he did just lose his mother. No matter how you look at it this Bulma will never truly understand what he went through. I feel like he should be a little more reserved for instance when Bulma asked how he slept he could have lied and said he slepted fine but, actually he had trouble sleeping because he's having flash backs of his mother or maybe that his bed is too soft and to him that uncomfortable because all he's ever had were old lumpy mattresses or slept on the floor . Trunks from Super had PTSD and would have little flashbacks of the destruction in his world whenever he would see familiar know something to separate him from everyone else, something for him to work through.

Wouldn't miss a Vegeta fight for anything.

Good that he's settling in I'm looking forward to the interaction between him and Vegeta only down side is no Goku black or future Mia as far as parrings go how about erasa she rarely gets any love or lime would also be a good choice since she already knows about saiyans

That's sad I always did hate what happened to miri bulma

After living a life of chaos and devastation, I imagine life at CC in this timeline will take some getting used to.

Can't wait to see how Vegeta takes him being back. Trunks should also be a good influence on Gohan.

nice

Finally another story about future trunks going back to the past and staying there! Nice story so far, can't wait for the next chapter! I would ship trunks with videl, lol.

I hope it gohanxvidel and maybe miraixerasa

This started out as a very good beginning of a good story. Hope there will be more soon. looking forwared to it.

Not much to say foe this one. Pretty short set up chapter.
