Summary
As a person, falling in love wasn't on the top of your priority list. If it happened, it happened, but you weren't all too bitter if it didn't. Maybe whatever social higher power wasn't too happy about that, so it just had to partner you up with some nerdy idiot who flew too close to the sun and ripped a self-shaped hole in the middle of reality itself.
And then you also fell in love with his brother. Too bad that you aren't too up for polygamy.
Inspired by Milk Tea and Souls by Lady_Flame96 and Soulfound by yeo_sin, Title inspired by Baile Involvidable by Bad Bunny

*You don’t have to read the previous fic to start here.
This is a continuation, but thanks to the amnesiac plotline, it should also work as a standalone.Series

Summary
The Horrortale Bitty Brothers are abandoned just like Hansel and Gretle. And in an effort to find food and shelter, they stumbled across a delicious Gingerbread house.
Pairing Nightmare Sans and Ccino Sans.
⚠️ Sad beginning, but Happy Ending.
⚠️ Hansel and Gretle level of child/pet abandonment and being lost and hungry
⚠️ Fairytale level of "horror", but still ok to see in a children's movie from the 1980's-1990's -

Summary
A collection of One shots featuring character I want to work with but don't necessarily want to write a whole story about, or just random ideas I wanted to write out.
I'll be adding more as I go.
Probably lots of fluff and good stuff. -

Summary
Noriko works for the Ebott police department in the newly established special bitty unit, her first assignment to go undercover to get into the bitty fighting rings now that the government has given the small monsters all the same rights as their full sized counterparts. What she didn't expect was for her first assignment to have a hiccup in the form of finding something unexpected in an ally on her way to make contact with her in into the rings.
Life in the rings was hell, being sold off to be a breeder was probably even worse. Though dusting in some filthy ally by the jaws of a mangy mutt was not the way he expected his great escape from hell to end.

Through Small Hands: The Bittybones Archives by StrawberyLover

Summary
In a world where miniature skeletons known as Bitties live openly among humans and monsters, researcher Dr. Y/N L/N is tasked with compiling the first comprehensive study of their existence — a collection of field reports that will define how the world understands them for generations to come.
What begins as detached documentation soon unravels into something deeper.
Through every encounter — a gruff Underfell bitty learning to trust again, a bright Underswap duo lighting up their home, a quiet Mafiaswap pair who speak in riddles and loyalty — Y/N starts to see the lines between science and empathy blur.Each tiny skeleton carries a fragment of its universe’s soul — hope, rage, love, tragedy — and as Y/N listens, observes, and sometimes reaches out, they begin to uncover a truth hidden within the multiverse itself:
that even the smallest beings can carry the weight of infinite worlds in their bones.

Summary
Life isn’t fair, case in point, you didn’t expect to be trudging through the snow to the corner store to pick up some much needed, over priced, feminine hygiene products while trying not to bleed all over yourself all because you failed to remember to pick them up with your normal shopping. That’s the thing, no one ever said life was meant to be fair did they?
~*~
Promises were just words, promises of home, safety, love. Only ever worth something if the person kept those words close to their soul. That was something he learned pretty damn quick. Built for love, to be a friend, a companion, tossed into the rings to be a fighter, something he was never meant to be. The only promise he knew he could trust were the few he made to himself, the promise to never fall for the sweet lies of a pretty face again.
~*~
What happens when two souls who honestly need each other, don’t know how to open up and trust? Can love, trust, and home be found when the world has proven that trust is a dangerous thing? Can they get over the hurt that this unfair world has piled on them? Open up to each other and maybe, just maybe find the home they both need? -
