Me and my brother become sans and papyrus from our own story!?

What if two brothers somehow end up in their own story as the sans and papyrus that they made? They called the story starfell, mostly because everyone in the story is like a tsundere, or something similar. They may act like they dont like each other and act like they hate each other but it's the complete opposite. What if after they finish learning how to use their magic, they end up in undertale with a lot of different sans and papyrus from different au's or universes.

(Request which sans and papyrus you want in the story, I got a few in mind, but I want some more to put in the story before this sans and papyrus is there. Personality might be different, things will be different, I'm probably going to be horrible at making this. I got this idea from a few people from ao3, they made a stories with becoming a sans and papyrus or just a papyrus by themselves or something like that. I don't remember their user name, I remember one of the names to one of the stories that was made, it's called Vindictive care ao3 I believe, you should go check it out, it's awesome)

Also to warn you that I also made up the stats on spot, it's not supposed to be realistic but made up kind of thing so don't complain about the stats or something and

Also to warn you I'm not good with puns since I never made one so don't expect them to be good or anything

You can also request a chapter on what you would like to see or read next
