Summary
Long ago, deep in the quiet woods of the Underground, Grillby sought only solitude. He never expected to find a fallen human woman-wounded, frightened, and far from home. Against his better judgment, he took her in. At first, it was duty that kept her hidden and safe from the Royal Guard. But when her laughter began to fill the spaces between his silences, protection became something deeper.
When word of her existence spread, Grillby made a dangerous choice: he marked her under his protection, binding her fate to his flame. Their bond grew-slowly, tenderly-but like the flowers she loved, her life bloomed briefly. And then it ended, leaving only memories and ash.
Centuries later, on the Surface, Grillby runs a quiet bar and tells himself he’s content. That is, until a new regular walks through the door - a woman with the same gentle voice, the same curious eyes. There’s something achingly familiar about her, like a dream half-remembered. His flame stirs, warmer than it’s been in ages.
But can love reignite across lifetimes?- Language:

ten to one anthology (on hiatus) by theseventhsmilingfriend
Fandoms: Undertale (Video Game)
23 Oct 2025

Summary
“I CAN’T OPEN THIS BLASTED BOX!! IS THIS SOME KIND OF JAPE?! WHY WOULD HUMANS SELL SOMETHING LIKE THIS?!”
The sound of a trombone plays.
“SANS!! WHAT DID I TELL YOU ABOUT PLAGUING MY LIFE WITH INCIDENTAL MUSIC?!”
“that you love it and want me to do it more?”
“SANS, I WILL DUST YOU.”
“pretty sure that’s workplace harassment.”
“IT IS NOT!”
“is too.”
Envy closes her eyes and tunes them out again as their argument devolves into yelling. She just has to get through today, tomorrow, and the rest of her life. That’s not so bad.(AKA, a less-than-pleasant dojo owner who has too many problems of her own to deal with forgets to take down a "help wanted" sign.)
Please read the before-story author's note of the first chapter!

Summary
THE GREAT PAPYRUS PROBABLY DOESN'T NEED FOOD!
...probably being the keyword there.
But it's an experiment! A very scientific, very important experiment! And it has absolutely nothing to do with how disgusted food makes him feel!
Sans can't know about it. It's not that he doesn't trust him, no. It's just that Papyrus knows Sans wouldn't like the idea of his brother trying not to eat for a whole month.
or
Eating never came easy for Papyrus. The taste, the texture, the strange disgust that followed... none of it made sense. But when he hears skeletons might not need food at all, something inside him clicks.

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!
