°*⁀➷ YANDERE OCTOBER 2025 ; DAY 1 — LOVE LANGUAGE ┆彡
Quality time. Quality time?
You don't see him as much anymore. Which is weird. There was a point where he could barely be apart from you.
He's disappearing to stars know where, leaving you and Papyrus for hours long. Sometimes even days. Unannounced. Unspoken.

Summary
When you were ten years old, your parents sent you to stay with a relative of yours from Ebott. Their villa was situated up on the mountainside, and you loved to explore the forestry. One day the ground gave out and you fell Underground, and faced terrors beyond your imagination. You were missing for weeks.
After you managed to miraculously return to the surface, your parents were relieved - but deeply troubled by your 'delusional ramblings'. They were convinced you were 'crazy', and feared how that would reflect on their reputation. Your doctors advised sending you to an in-patient psychiatric facility, which is where you spent the next few years in intensive therapy and counseling.
15 years later, you're a young adult with a somewhat manageable grip on life. You keep your head down, attend the social events that are expected of you, and try to be as unnoticeable as possible. Your parents arranged a suitor for you, and you're to be wed within the next year.
That is, until, those monsters your parents and doctors tried to convince you weren't real suddenly crawled out from the Underground. And they're a lot different from what you remember.

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
The daughter of a politician and a successfully business man being kidnaped and held for ransom was something you only heard about in stories, rare true crime specials that didn't happen to regular people. Until it happened to you.
Now in the middle of a blind panic your father has purchased several Monsters to make sure it doesn't happen again, using what might have been shady business dealings to get special permissions for them. You never asked about how your dad had so much money, or how he was always able to pull so many strings, but maybe you really should have. -

Summary
You died.
Plain and simple, one moment you were there, strapped to the table in that ever so dark laboratory. Then a loud cracking had occurred - the sound of your own soul giving up. It had been deafening, like ice breaking beneath your feet. That purple crystalline heart shattering like fragile glass, unable to persist any longer.
The testing had been too much for you, not even you could persevere through it. Not after months—years.
You…died?
Then why were you here? More importantly where? What had
Gasterdone? And why did reality seem to glitch in and out with every painful thrum from where yoursoulshould be? And who were these skeletons that felt oddly familiar to yoursoul.>> Persevere?

Summary
Being the cleric of an inter-dimentional war isn't that bad once you get used to it.
When a skeleton falls from a portal into your bedroom, rambling about things you'd always thought were fake, what would you do with everything he says? When he claims he needs to win a war against his very own brother, his bone and marrow, who are you to turn down his request to be his army's medic? When you realize you're falling ill, who are you to tell him something is wrong?

Summary
The world changed when the barrier broke. With the monsters and the child ambassador came an influx of new diseases that are barely understood. You're a young scientist and have been called upon to work with monster-kind to help treat these strange new conditions, but you begin to notice that you have changed alongside the world - more so than you could possibly imagine.
High jinks and low jinks ensue. WARNING: contents include spicy bone-zoning, VERY slow burn, painful hanahaki experiences for the mc & more :))

Summary
Gonna try my hand at this for the first time! These will all be Sans/ Reader, but might play around with various AU's I don't normally mess with.
Might also sneak some canon or not canon scenes in here from my fics if they fit hehehe.
Also going to try to do some of these with Gender Neutral readers, which I am not very good at but gonna get some practice in! GN Reader will stand for Gender Neutral reader.

Summary
You'd never expected to be one of those people who bonded with a random stray, and if you did, you never expected it to turn out like this. The tiny... blob of an animal was cute, affectionate, and melted your heart before you'd even named him. Unfortunately, not everything is as it seems. You've met this lovely creature before, and he definitely remembers you...

Summary
You should be dead. Everyone else in this god forsaken city died as soon as the barrier came down and these creatures, these MONSTERS, invaded Ebott City. You got lucky, or maybe not.
You had the bloodline of a mage. Which meant you could create barriers. In a moment of panic you had created a barrier in your apartment, locking you and your neighbor inside, and the monsters out.
But now the clock was ticking and you had a group of skeletons sniffing around your apartment, telling you that they couldn’t wait to drag you back to their den.
They meant as food…. r-right?
