They had just made it to the surface, after the end of yet another pacifist ending. Yes, this was usually a good moment in its own, but Sans has learned that the more happy he was now, the more depressed he would be later, after the reset.
He had given up all hope of ever actually living on the surface.
When Frisk quietly tugged on his coat sleeve and asked to talk to him, he was a little suspicious.
"Sans?" They asked, signing while they talked. They rarely spoke, and when they did, that always used their hands.
"Sup kiddo?" Sans asked, putting his hands in his pockets.
Signing, Frisk said never again, Their hands waving in front of their face and across their body.
"Never again what?" Sans asked cautiously, trying to keep the hope to a minimum,
Never reset again. Promise.
Sans tried to keep the hope from exploding through his bones, but he couldn't help it. Suddenly he felt lighter the. He had in years.
But as the days went in, Sans was still suspicious of the reset, the thought always dark in his head. That kept him from being as happy as everyone else.
But then a week had past.
A month.
Two.
Sans was more hopeful than ever.
He absolutely loved the surface. Everything was fresh and big. There were buildings taller than Asgore's castle, lakes bigger than all of Snowdin. The surface was the most magnificent thing he had ever seen.
There was so much to see, so much to learn! And after 3 months on the surface, Sans had decided to get a job. It's been years since he had a real job.
He was getting happier and happier everyday. He finally felt like he belonged somewhere, that he was loved, had a family.
He finally stopped giving up.
