Summary
Falling into the Underground wasn’t on your to-do list. Falling for two skeletons definitely wasn’t either.
Blue is sunshine bottled in bone—sweet, loud, and determined to make you smile even if it kills him. Rus is quiet, steady, and the kind of person who remembers your favorite tea. Between the two of them, you’re constantly flustered, overfed, and very, very loved.
When both brothers realize they’ve fallen for you, chaos ensues—except it’s the polite, apologetic kind of chaos where no one wants to hurt anyone else. What starts as a tangle of awkward affection becomes something honest and warm: a relationship built on trust, laughter, and a whole lot of skeleton hugs.
“WE CAN SHARE THEM!” Blue insists, bright as ever.
Rus sighs. “That’s not how dating works, bro.” -

Summary
It's been six months since monsters left Mt. Ebott. In that short amount of time they'd manage to blend into society as best they could, save for the heart of the city. Anti Monster gangs run those streets, scaring many of monsters away. These gangs forced monsters to stay on the outskirts of the city, close to the mountain. Then one day, the university that you work at dared to break social norms and hire a couple of monsters. Nothing could prepare you for what would happen next.

The Chemistry of Love - Remastered! by MischievousManiac

Summary
It’s been nearly six months since monsters broke the barrier and moved out from under the mountain and alongside humans. There was a lot of panic when they first surfaced. Suddenly, these beings of myth were no longer just myth: they were living, sentient beings that want to be given a chance to live and grow just like everyone else.
Maybe it was their calm demeanor that kept most humans from lashing out violently at them. Or maybe it was because they surfaced with a human child that wasn’t afraid of them. Either way, monsters slowly started working their way into the city. The neighborhoods and shops near Mt. Ebott were the first to accept monsters rather than turn them away.
Since you lived a little closer to the heart of the city, your life wasn’t altered all that much by their appearance. Every so often you would hear hushed whispers that some monsters tried coming further in only to be driven back by the Anti Monster gangs that started to plague the city, but you had never seen one. Certainly, never dreamed of working alongside one, only to fall in love with him, either. But fate is a mysterious thing.

Etiquette of Possession by Pipsqueak (Skyhon)

Summary
You raise your eyebrows and gesture towards the back. “By all means. You’ve not introduced yourself to the others here… although I suppose that makes sense, given your mission.”
“i think that mission is a lost cause, to be honest. kris is sorta impossible to find a match for.”
“Well,” you say, “at least there’s wine, then.”
“exactly.”
There’s a pause in which you both lock eyes and blatantly stare at each other, but this time there is not a hint of hostility. It must last nearly a full minute. Somehow, this experience is not at all uncomfortable or weird. Paradoxically, the fact that it isn’t weird makes it weird.
“care to join me?” he finally asks.
And who are you to say no?
—
Or: Sans is the Judge, and you... you are something else. Something that's been sleeping for hundreds of years, under the Deltarune Palace. Something he’s needed, and finally has.
Unfortunately, being possessed by a spirit of violent judgement kinda has its own quirks, and Sans is really fucking stubborn.
Fortunately, so are you.

Summary
Here we are again! Another series of Undertale one-shots following the Fictober prompts and featuring the skeleton brothers as love interests to either my nameless or named girlies.
Just like the past two years, if you'd like any of these to be turned into fics, then please let me know in the comments! If enough people show they're interested, then it'll be added to my list of future fanfics! Five requests are what's needed for them to be added.
And if you choose to wait till the end of the month to read, that's okay! Requests can be made up until November 7th, when I post the list of the lucky winners!
Hope you all enjoy!

Summary
You, dear reader, have been transported into your own AU — as Sans.
Just when you’d begun to settle into this new, bone-white life, one small mistake sends everything spiraling.You’ve fallen into a world inspired by one of the fanfics you used to read religiously — the typical fanfic harem story where a broke college student named Y/n accepts an offer from their childhood friend, Angelica, to move in with her many “roommates.”
Normally, the tale would unfold the same: rumors, misunderstandings, heartbreak, and eventually love.
But with you here, the script is already breaking.Will you help Y/n? Sabotage them? Or maybe twist fate and match them with someone else entirely?
Whatever happens — the story will never be the same now that you are part of it.

Summary
A collections of first chapters of fics I want to write in the future... when I'm done with my other fics. Check chapter summary's for more info on the story in that chapter. Stories will only get one or two chapters here before eventually migrating to their one story. It's a way to show concepts of an idea.
Since it will take me a while to get to write any of these out properly please feel free to take their first chapters and continue the story yourself! I would love to read them :)
Starting off strong with a Wine x Reader story. Reader finds herself reincarnated after her husband killed her, she's determined this time to survive her loveless marriage and make it out the other side.
