A remastered retelling of my original story, "Why all the abuse?" Believe me, this story will be much better. Abuse comes in many forms and when it comes to Sans, he's experienced almost all of them. He can't tell half the time when someone's being nice or just pulling his leg. Regardless, this is a story about an abused Underfell Sans who falls into another universe. One full of comfort and no cruel jokes to accompany it. A place he finds himself loving more and more each day all while his brother is back home and is left alone for the first time in years with no one to keep him sane. 'What if Sans never comes home again?' He wonders. Still bad at summaries, my bad. Also, don't let the first chapter's word count discourage you. The other chapters are 1,500 - 3,000 words each.

[^w^;] So... New description and cover art! Yay! Ok, let's go! "What's the point in existing, when you're worth nothing?" We all know that the Underfell Underground is one hell of a place to live in, literally! So why should someone as weak, yet adorable, as Sans be living there? He's trapped, he can't get out and all he has left is his brother, Papyrus, who he calls Boss. Not that Boss is helpful, all he does is degrade him and make everything worse. Why should he have to suffer as much as he does? Why can't he just have a better life? ... Why can't he just disappear? Be careful what you wish for, they say... GAH! I STILL SUCK AT SUMMARIES! BE READY IF THIS SUMMARY SUDDENLY CHANGES! {News flash: It did. ^^^} (READ) Changed it, no fontcest, or at least, it wasn't intended that way. However, you guys can still interpret this the way you want! Also first chapter is all my tags because wattpad won't accept them T^T Why wattpad? Why...?

Please for goodness heavens, don't comment if you're really young, I had to delete enough of cringy comments. Also please don't leave any suggestive comments, there's a reason why this book doesn't have lemons (aka I'm sex repulsed). Just some one-shots about Error!Sans. Mostly fluff and some angst. Basically me throwing here whatever comes to my mind. Error is short, not because I said so, but because it's canon. In some chapters ships are directly shown, while in others they're not. If that's the case then they're probably friends, but there's nothing stopping you from seeing them as a ship. (Cover belongs to yufy01 on tumblr)

Nightmare is a simp for Error thats all ya need to know.. love at first sight? slowly falls into simpness? Will Error like him back? maybe..idk..read to find out Also Error is a semi-top while Nights is semi-bottom.. I put semi cause I don't see much of top Error and bottom Nightmare so it might be difficult for me to write them this way correctly with correct personalities and all °~°

Error just about had enough of the abuse, the pain, the suffering. He just wanted to end it all, no one wanted him right? nobody cared, r I g h t? it wouldn't matter if he was alive or not. He was meaningless, hopeless, no purpose whatsoever. Did it really matter? He protected the multiverse despite all the hatred, he saved them, but nobody knew, nobody C A R E D. So, he jumped, or did he? Fgod made by harrish6! . . . . . . . Author's Note; This story is long and confusing. And the plot will be changed and compromised but will be keeping some key elements and Aus/Multiverses the characters will travel to. Everything else that makes the story too muddled or unnecessary will be removed in the New version of this book. Please read the tags if you want to know what kind of ships there are here...

First time posting so try to work with me people. Error now lives in the Creepypasta AU world after jumping in the void. He would be considered the Puppet Master. About to be on a unwanted adventures, wondering how he adopted certain terrors, confused of gaining suitors, and oddest yet strangely satisfying friendship. Along with trying to live well "normal" as he can be...Who he kidding he should have scene this coming. Better this than Fate. Better explanation later and the idea be on the first page. FgodError concept and idea belongs to @harrish6 Story Idea belongs to @Glitchy_Shadow Art doesn't belong to me but its owner Undertale own by Toby Fox. Creepypasta characters belong to their owners.
