Basically how I imagine Au Sanses are as yanderes.

Papyrus finds himself curious about the machine Sans has behind their house. When he accidentally activates it, he ends up sending himself to the world of Underfell. Meanwhile, Underfell Papyrus is sent to Underswap and Underswap Papyrus finds himself in Undertale. Now they must find a way to swap back to their own universes.

Sans has been beat and tortured for most of his miserable life, almost exclusively by his younger brother, Papyrus. But, what happens when Sans is ripped from what he knows? How will Papyrus react? And, more importantly, where will Sans end up? Papyrus has abused and belittled his brother for the majority of his life, unable to see just how much he had hurt the one person he cared about it his life. When he is lead to believe he has dusted his older brother, he loses all reason to live. What happens when he dies in Underfell, only to wake up in a completely different universe? Will have both HoneyMustard and Edgeberry. No smut, sorry :P

cover and possible art in the book isn't mine neither are the characters. I credit if I know/find the artist. I only own the storyline. No one knows when or why they appear but everyone has a special diary that's connected to your soulmate's. You can see what they wrote and vice versa. It might sound easy fore you can just tell your location to your mate but the diary doesn't share that kind of information. This is the story of Sans, Sans the Skeleton and how he found the love(s) of his life. Everything is in Sans's pov unless told otherwise I edit quite often but try to write new chapter weekly, I'm kinda irregular though.

-Starts with UnderSwap- You were at home with Chara, enjoying a regular day. Since you'd gotten to the Underground, you'd become close friends with many monsters, even if your soul was what was needed to free them. You were about to eat dinner with your friends when disaster whisks you away from your home and into a realm where you're left alone and helpless.

When nightmare is told he isn't a king, he must marry to become one. He doesn't care about who, he just wants the name. Will he find love? Welp that changes when he finds out about one of dream's love potions......

Nightmare found a young child a long time ago. When they fell into a coma it sent him over the edge. several hundred years later the child wakes up in a castle of darkness, surrounded by people, er... skeletons, that they don't know. Now they are being raised by murderers, cannibals, and world destroyers. Oh yeah! And their Uncle is the god of Death. Fun. WARNING (but not really): This story has been known to give people heart attacks and possible death from wholesome cuteness. I am not responsible for said medical emergencies or deaths. Read at your own risk. ~~~~~~ || Few things. 1) The first couple of chapters are going to basically just be Nightmare, but it's for plot reasons. 2) Dream is definitely going to be a little ooc. Don't like it, don't read. This is just for fun. 3) Like I said, this is just for fun. So, updates are when I feel like it. 4) I'mma try to keep the pronouns for (Y/N) gender neutral, but I may just drop that at some point. Depends mostly on what you guys prefer. 5) any art or videos added are not my own unless explicitly stated. Cool? Great. Let's get started.
