Note: The premise of this story is based around if Frisk stopped reseting, but leaving the world without an ending. It's like they never existed. The only people who remember are Flowey and Sans.

"How many times has it been now partner? I've lost count." Chara said, to Frisk.
"I think at least 40 now." Obviously they were talking about the resets, of which Frisk was sick of. She'd talked to everyone, fought and spared them all. Killed everyone, from Toriel to Sans, and they had had enough. They were sick of it and just wanted a way out, but could not see one.
As they pressed the reset button once again, a thought crossed their head as they stared at the instructions screen.
"F4...". The way that Frisk controlled the main menu, was through a keyboard, and sure enough at the top there was a key called F4.
They promptly pressed it, and the whole screen was brought to a minimal size.
"Hey, what do you think you're doing?" Shouted Chara, agitated about something.
Then Frisk saw it. A big, shiny, X button. She quickly moved to press it, as Chara was screaming insults at them, telling them to stop.
Frisk had no intentions to, and promptly pressed the button. The world went dark. Dark, darker yet darker.
All Frisk could see was what appeared to be a black blob, with a smiling mask.
"Now you've truly screwed up Frisk. Do you know where we are?" Chara asked rhetorically.
"We're in the void. A place where it is unescapable from. That blob standing over there is the so called "Man who speaks in hands" W.D Gaster.
He did the exact same thing you have done. There is no escape Frisk, so congratu-fucking-lations for condeming us to an eternity of lonliness."
The blob standing opposite them seemed happy. He knew no harm could come to his sons now. The two devils were condemned to an eternity in hell.

Sans awoke to the typical drum of Papyrus' shoes outside the door.
This is always the place that he is when the little devil resets. He swore under his breath, as the last run had been one of many in which he had gotten to the surface.
He knew it was fruitless to even hope that there wouldn't be a reset, but you know how it is.
Papyrus slammed open the door to Sans' room. "SANS, PICK UP YOUR SOCK! NYEEEEEEEEH" Papyrus yelled as he threw Sans' prized sock at Sans.
Sans was a bit hazy in getting up, and this resulted in the sock becoming stuck in Sans eye socket.
"OH, I AM SORRY DEAR BROTHER." Papyrus said.
"Heh, no worries, but eye could use a little help," Sans punned.
"OH MY GOD SANS THAT ISN'T EVEN FUNNY HOW COULD YOU DO THIS TO YOUR DEAR BROTHER?!" Papyrus whined.
"Ah I'm sorry bro, but seriously, get it out please." Sans said, feeling the sock in his eye socket and at the back of his head at once, it felt... disturbing.
"NYEHEH, ALRIGHT BROTHER" Papyrus cackled.
As the sock was extracted from the skeleton's eye socket, Sans realized he was particularily tired. He felt like he could sleep for a couple years, maype a dozen or so.
"OH DEAR, WE ARE LATE FOR OUR SENTRY JOBS! SANS WE NEED TO GO!" Papyrus shouted.
"Hey give me a minute bro I just got up." Sans wearily spluttered.
"NO TIME LETS ROLL" Papyrus shouted as he picked up Sans under his arm and bolted out the door. That's something good about Paps, he's extra comfy even though he's all bones. He had the warm feeling in his soul that everything would turn out alright.

"Ugh, where is that little brat." Flowey said, enraged. They were normally in here by around 5 minutes ago.
Flowey decided that he should probably see what they were up to, and he dived underground, into the previus room.
However, when he arrived, there was nobody there, just the buttercups.
He heard footsteps coming, and he dived underground.
Toriel walked through the door, and had a survey around. "Hm, no humans today. I had a peculiar feeling there would be one..." She said.
Flowey was outright confused. "Chara?" He whispered. "What happened?"
