what happens if you were there instead of sans in 0.0 ?
what would have happened if cross took a human soul instead?
would it change the entire timeline of underverse or just... leave it as it is?
would you die in a try to stop the x event, or ,will you fail?

...and most of all.. who are you?

------------------------

just an idea i had while wanting to see what would have happened if there was reader insert and there isn't a lot of those online..
beacuse all season 2 didn't come out yet I'm going to focus on season 1 trying to not get too lazy and discontinue the story if you like it leave a comment it would mean so much to me see ya in the fanfic

Also, y/n is using all pronouns(didn't want to only do they/them, and is aroace(don't expect ships at all in this fic, it is focused on the story)
