Summary
Dream isn’t quite sure what to make of his new teammate. He’s brash, brazen, and nothing less than completely and utterly dedicated to the art of half-baked answers and bewildering behavior. The Wanderer; The True Guardian. Ink keeps his secrets close and his vials even closer.
Those vials.
Dream wants nothing more than to know.
or
Eight times that Dream sought an answer, and the one time that Ink gave a straight response.

Summary
Epistles and professions— along with a complete lack of professionalism. Dream begins hoarding letters heralded by a mysterious feline. An oddity, he has noted, is the devoid signature on each and every parchment. Abashedly fond of the risqué humor under their veil of anonymity, Dream continues accumulating these sanctums of vulnerability— a casualness he has longed for since his 494 years of slumber.

Personal Interpretations on the Sans Ensemble.

tldr: Killer attempts to swoon Dream and gets clowned on. That’s the plot. Let’s hope Nightmare doesn’t catch wind of this.

Anyone that watches porn regularly has a favorite actor. Someone that they keep coming back to and that always manages to turn their breath short and make their heart slam within their chest no matter how often they watch or hear them.
And for you, that was ‘Big Red’.

Summary
How can you not be sure? Silly skeleton. I either look fat, or I don’t. It’s simple.”
“YOU LOOK FINE! YOU LOOK HAPPY.”
My heart drops and I can’t exactly figure out why. “Happy?” My eyes hone back in on the mirror. Back on The Butt, like my ass has any sort of effect on how happy I look. “But does my butt look bigger?”
“AS COMPARED TO WHEN, DEAR?”
I don’t know. Maybe to when I was a newborn. Or a microscopic sperm cell. “Um. A week ago?”
“LOOKS NORMAL TO ME.”
“Normal,” I sigh. “Try to fit your hands around it. Come on, just try.”
He clicks his tongue. “I DON’T THINK THAT WOULD BE VERY HELPFUL.”
“I guess you’re right.” I say, sounding defeated.
“…WELL, MAYBE YOU DON’T LOOK SO HAPPY ANYMORE.”
“Really?” My eyes light up, and I look back at the mirror. On second thought, I think my butt might have gotten smaller.
“WAIT—NEVERMIND.” He shakes his head. “I’M CONFUSED.”
I laugh at that one. Because if Papyrus is confused, imagine how the hell I feel.

Summary
Frisk’s dad Sans and uncle Papyrus are royal guards. That’s pretty much all Frisk knows about their jobs. Frisk doesn’t know much about their past nor what they actually do for work. All they know, is that they have to wear their monster disguise every day or they’ll be caught. They know that humans who are caught in the underground die. But what happens when Frisk slips up and accidentally alerts the whole of the underground to their presence?
Sans is struggling hard trying to balance being a parent and his job. He wants to be around for Frisk, but he has to satiate Asgore lest he find out Sans’s secret.
Papyrus really wants what’s best for his family. He’s worried about Sans and how stressed out he’s been. Sometimes he worries that Frisk doesn’t have enough social interaction.
I’m so excited about this, I’ve been working on this project for 3 years at this point and I’m so so so happy I’m finally able to post it. It’s still a work in progress, but it’s going well so far! Constrictive criticism is appreciated, especially if you catch a spelling error of mine (just be nice about it please).

Summary
In Woventale, the Underground is a patchwork of strange cities and altered destinies, where familiar faces walk unfamiliar paths. Across the stitched landscapes of Snowfall, Sea Shore, Smokestack, and the Forest Ruins, lives intersect in quiet, calm, or sometimes dangerous, and unexpected ways.
This is the world woven by 'Watchers'. Like you. So why not stay awhile, and listen?
This - is not a grand story. This is a collection of short stories, moments, scenes and encounters.

You are in every universe, in every timeline. Each variant of you is different, but there is one trait that always stays the same.

Summary
Frisk should be fine.
Everyone is on the surface, the sun is shining and bright, and their family is blissfully happy as they pursue their dreams in a world they’d thought locked to them.
Frisk is fine, because this is what they always wanted. So what if their scars ache and magic flashes behind their eyes every time they blink? So what if the copper of blood rests thick on their lips? So what if terror catches in their throat and stills their heart when their family ruffles their hair?
All those hands that have hurt them are achingly gentle now, and there’s nothing wrong anymore. There’s nothing for Frisk to fear.
It’s just the occasional (frequent) bad day, and bad days pass.
So Frisk chokes back bitter accusations that bubble up like poison on their lips, because Frisk isn’t allowed to be anything other than fine.
—
“You hurt me! You killed me! Of course I’m scared of you! How could I not be?!”
The words tear out of Frisk’s raw throat, and they don’t bother to choke back their sob this time, their hands shaking too hard to sign.

Summary
They said no one who climbed Mount Ebott ever came back, but you weren’t “no one.” When Y/N falls into the Underground, they awaken a story that’s been repeating for years… one of monsters, souls, and a lazy ass skeleton who’s seen it all before. But this time, something’s different. The resets don’t feel the same. The laughter doesn’t sound the same. And Sans, the lazy, pun-loving sentry, starts to wonder if maybe this is the one timeline worth breaking the rules for.
In a world where everything resets, what happens when someone finally makes him want to stay?
