In Which You Become a Multi-Dimensional Pen Pal With Yourself by Idontevenknowwhatthisis
Fandoms: Undertale (Video Game)
26 Aug 2025
Tags
Summary
"Resets", which you only actually learned about this morning, were a freaky time phenomenon which allowed something to travel to the past repeatedly. That "something" was a human, and that human wasn't actually human at all. That was what your journal explained to you.
(Or, Sans doesn't remember the resets, but he knows about them and he has to deal with it.)

Kris can tolerate everyone... Everyone except for you, it seems.
Kris dislikes you, to put it lightly. They just can't stand you, and yet you're so persistent.
... Maybe they find you just a little endearing.

Summary
You'd never expected to be one of those people who bonded with a random stray, and if you did, you never expected it to turn out like this. The tiny... blob of an animal was cute, affectionate, and melted your heart before you'd even named him. Unfortunately, not everything is as it seems. You've met this lovely creature before, and he definitely remembers you...

Not that he would ever directly say so. He isn't very good with words in that regard, but...

I make no promises that I'll have 31 one-shots for y'all to read, but damn I'll do my best to give ya somethin'.

Summary
Two days ago, you said goodbye to your best friend. Yesterday, you lost your job with no prior notice. And then today, you had a fight with your mom. So that’s your day today. Lonely, fighting with your mom, jobless. Perfect Day for a drink or two, right? What's that on TV about monsters?
You didn't expect the monsters to accept that application for a social media job you sent them while you were drunk. Now you've suddenly moved to Ebott and spend your days hanging out with monsters, documenting your weird new life, and marvelling at how different monsters and humans can be - and how similar.

Summary
On the day of their 13th birthday everyone has a name appear somewhere on their body. A script different than their own, but still familiar and comforting nonetheless. It's said to be your soulmates handwriting and, when you make physical contact for the first time, it's to change to the color or their eyes. Or so the rumor goes. But everyone knows that's just an old wives tale since finding yours is so far and few between.
But then there's Fanchon. What the hell is she supposed to do with 12 soulmates?? At least her odds are better than most...

Summary
A great source of despair draws Nightmare to an abandoned AU. There he finds an unfinished Sans with no name, no companions, no purpose, no world, and a soul. Nightmare gives him the option to get out of his abandoned, empty world. He accepts the offer but refuses to destroy anything or hurt people. Instead he finds another purpose. In return the Bad Sanses give him a home, companions, a life, and a name. They call him Ink.
Or: Before he can destroy his soul and enter the Doodle Sphere, Ink is recruited by Nightmare. He accepts his role as best he can, even if he sometimes feels like he is meant for something more.
