DUSTTALE

Your name is Sans, Sans the skeleton. You are fairly popular around these parts, known for being a sentry in Snowdin, running an illegal hotdog stand, and of course making bad jokes. The universe wasn't very nice to you however, you've been burdened with knowledge no one should ever have to bear; you are trapped in a time loop where anything and everything you do can be undone with the press of a single button and you couldn't do a thing about it. For a long time, the person with that kind of power was Flowey. You and Flowey never really got along, but your brother, Papyrus seemed to like him so you never paid much attention to him. Even when he did attempt to commit a genocide, you were always able to stop kill him and make him stop with your smart attacks, and planning. You can actually remember previous timelines unlike other monsters, so you know quite a lot about this kind of stuff, unfortunately.

Life was already miserable, but it only got worse when that power to RESET time was given to someone else. One day, another human fell into the underground. This was the first human you've met since you and Papyrus only came into Snowdin recently, you were nice to the human at first because of a promise you made to a friend.

Sooner or later though, that human turned out the same way Flowey had. They began killing everything and everyone, but this time you couldn't stop them, humans were always stronger than monsters. No matter what you tried, teaming with others, fighting them in a weaker state, reasoning with them, they always killed you and RESET the world.

But one day, you realized something, they only got strong because of LOVE. What if you take their LOVE from them? What if you...kill everyone? You could overpower the human and stop the loop. Maybe...-

Someone is at the door. It's Papyrus, your brother.

“SANS! YOU'VE BEEN IN YOUR ROOM ALL DAY! ARE YOU OKAY IN THERE?!?”
