5 years. 5 years it's been. 5 years since Frisk freed the monsters. 5 years since your mom left you. 5 years you've put up with your father. 5 years of suffering and anguish 5 years of torture and abuse, mentally and physically. But that was gonna be stopped. ~~~~~~~~~~~~~ Meet (Y/N), a abused runaway with an attitude that's bound to make some people pissed. Well, that's kind of an understatement. After her mom leaving and being beat by her dad, she decides to run away, and finds a completely different world. One that makes her struggle to survive. How could she possibly make it? ~~~~~~~~~~~~ Meet sans, the laid back, lazy, and funny skeleton monster from the underground. At least, that's what he used to be. Now, he's known as Gaster Sans. He's still funny, but in a different way. All the laziness is gone. He's charming, clever, and quick. Ever since he combined souls with Gaster, his personality and appearance completely change. Will he ever feel the same, normal, again?

Why does he even bother? Nobody cares. Nobody sees. Sans thought to himself that he was better off dead anyway, and there was nothing left for him here in this horrible, horrible world. Sans slammed the back of his head against the machine he was slouched against, willing himself to die faster. This will all be over soon, right? I did not create the AUs that appear in this fanfiction. These AUs are based off Undertale, a game by Toby Fox.

"hey, Paps," he said, causing his brother to blink in unmasked surprise. He hasn't called him that in years. "you wanna hear a joke?" ー 〉I didn't write this to try and romanticize abuse in any form, this was honestly a vent but I really think there's more to their relationship then abuse and that's what I wanted to convey 〉TRIGGER WARNING 〉Ongoing

WARNING: Lots of swearing, blood, cruelty and slight sexual themes!!!! Sans and Y/n are arch enemies. They can't go a second without insulting the other. But one day an...accident happens, forcing them to co operate until they find a sulotion to their "situation". But before that, they learn a lot about each other and maybe, the hate they held for each other, will transform into something more...something beautiful
