So, it just so happens that the core is going into meltdown and someone had the awesome idea of asking its creator to help. Small problem with that though... he apparently kind of doesn't exist anymore?! How to resolve this? Simple, send someone into the past, namely you, to go and ask them. With everyone's hopes and dreams resting on your shoulders, let's just keep our fingers crossed and hope you can convince the monsters not to kill you and persuade the one and only W.D. Gaster you're not a lunatic and get help. Surely it will go just smoothly, right? No problems at all. I mean, it's not like you're going to fall for a guy that will eventually disappear from existence, right? You must ENDURE!

And this skeleton just laughs at you for it. -this fic has lots of cussing in it, and is a slowburn!- -if you have any suggestions of drabbles i should write for the story, comment!- all gaster!sans fics are way too serious to my liking on here, so I made more of a slice of life/comedy fanfic! hopefully this will go well HOOWEE Cover art by junkpilestuff on tumblr!!

You were created a long time ago, by Ink, to be his successor after his sudden disappearance. You were left within a distant void that is hardly in contact with other worlds--thus relatively hard to enter. But one day, Error finds your world and is ready to destroy you the moment he gets his hands on your soul. Falling into a new AU while trying to escape him, you may have met your soul mate. **This story is currently being rewritten! The plot line stays just about the same, the only thing I'd say changes a whole lot is the quality of the story itself.

𝘍𝘳𝘦𝘴𝘩 𝘚𝘢𝘯𝘴 𝘹 𝘙𝘦𝘢𝘥𝘦𝘳 | 𝘙𝘰𝘰𝘮𝘮𝘢𝘵𝘦𝘴 𝘈𝘜 You were expecting a quiet college roommate. Maybe a little awkward, maybe a little messy. You were not expecting Fresh. He's loud. He's neon. He wears Heelys in the cafeteria. And now? He's crashing into your life-literally-and moving into your two-bedroom apartment. You and Fresh couldn't be more different-he's all chaotic energy and bright colors, while you just want to pass your classes and keep your sanity. But between late-night takeout, emotional baggage unpacked at 2AM, and one too many accidental heart-to-hearts, something starts shifting. This was supposed to be a normal semester. So why does your heart start racing every time those stupid wheels squeak down the hall?

Want to talk about falling into the wrong place at the wrong time? Y/N definitely scored big time on that one. One moment she's falling, the next she finds herself trapped underground with a monster that wiped out his own kind. He's a cold-blooded killer that never shows any emotion. Though, as time passes, she finds out that Sans isn't as heartless as he plays himself to be. Hello! Writer~San here! Cover art and Undertale AU/Characters aren't mine, but the story definitely is. I hope you enjoy it!!!!
