You thought your life was like any other fools. A tragic backstory, and then you grew up and had to work till you died. That's it. Not much... much... uh... not uh.... "Well uh.... skeletons?" Oh boy, shits about to hit the fan. ------------------------------------- This is a rewrite of 'Three Bitty Monsters' and there will be several changes, small and large. It will still have the same basic storyline, but it will be more accurate. Not only to the characters personalities, but how they'd act during the time. This will take place in the canon AU of Undertale but will start a week before the monsters are released, It will be a platonic story, and I will try to use a they/them reader. It's likely it will cover some hard topics, but you will be warned at the start of them chapter. There will be multiple ending, reaching from 'More True' to 'Less True'. I hope you all enjoy this story as much or more as the last version of this. Thank you.

Y/N's best friend Blueberry (also known as Underswap Sans) invited them to move into the shared/connected apartment next door. They could hang out all the time! It's an awesome opportunity and the chances of it happening again are slim. Being closer to friends means a lot, especially in this tough life on the surface. Blue has introduced Y/N to other Sanses before, and they've never had any issues with them. Even so, what happens when they find out that Blueberry now has a very creepy one as a roommate? His cracked-open skull and unclear motives for being here are a major concern. Still, it's not as freaky as the stranger's ghostly appearances and obnoxious actions. Blue says "he's just misunderstood." Should Y/N follow their conscience, warn Blue and run? Or listen to Blueberry's optimistic advice, and befriend their new neighbor? Hello! owo ... Undertale aus and art presented in this book are not mine. However, the story is 100% my work! I hope you enjoy it!

Moved from AO3 because of reasons! "You are the only maid (or worker in general) that serves for the Skeletal Household. It's a skele-ton of work, but you manage by keeping onto a fairytale dream."

(Y/n) finds herself in a bit of pickle when Ink Sans explains to her about the condition of the Sanses of the multiverse. No matter what, she is determined to help Ink Sans and Error Sans to find a solution, and protect the others from the hacker. Although, it turns out to be a bit more difficult than she thinks. The multiverse Sanses had been turned to kids, and together, they are impossible to tame. How will the trio manage the kids? Will Ink and Error ever tell her their feelings? How will Core Frisk react? How will turn everything back to normal? How will they fight Nightmare Sans? Will they win? Or will the multiverse be forever consumed with despair and misery? Let's follow (y/n) on her journey and see what happens next. I do not own the multiverse or any of its characters, I don't own you either. I do not own Undertale. I only own the added characters like Hacker and P.
