Summary
Papyrus is mourning, though he knows his lover is not dead. Only missing.
He’s only missing them to the point of wanting to rip his soul out.
——
You are not a person.
But perhaps a certain skeleton can make you one.
—————————
Or, reader is a shapeshifter that feeds off of love who hoodwinks Papyrus into thinking they’re his child. Does it count as found family if you stalk them first?

Summary
It was bright. Too bright, what had just happened? Flickers of memories passed through Sans’s mind in a whirl. “Doctor Gaster!” He heard a faint scream. It was muffled under his own screaming of his mind.
“Someone get the kids out of here!” Another voice said. The bustle around him felt as if it was going in slow motion. The colors faded from his vision as he collapsed onto the floor.
“Brother! Wake up!” A small voice peeped. Sans felt his consciousness fade. The nausea he felt was too strong, and he welcomed the darkness.OR
Sans is left to care for his rambunctious younger brother Papyrus, his health suffers as a result of overworking. On top of that: memories of the past plague his dreams. Sans must work to overcome his trauma while also allowing himself to be supported by those who care for him. Tags to be updated as chapters are released.

Thankfully, she has one ally she believes she can fully trust.

Summary
(CROSS UPLOADED FROM WATTPAD!!!)
Ever since the barrier was broken and monsters rose to the surface once more, it seemed like despite the odd reception that they received from the Humans of Ebott, everything was starting to take a turn for the better. But almost a year later, the others couldn't help but notice something different...specifically...SANS was different. The usual laid-back, wise-cracking skeleton was acting...strange. His smile was forced, he didn't tell jokes, he's deprived of sleep, and the demons that were thought to have been put to bed ages ago keep rising back to the surface to torment him. It was no secret anymore. Something was wrong...VERY wrong...but what?

Summary
......"It's a beautiful night today. The stars are twinkling, the crickets are chirping...On nights like these, villains like you, should be burning in hell"......
It was a simple, ordinary day. Just another reset. Telling joke and puns, making puzzles with Papyrus, forced grins, hourly naps, breaks from his multitude of jobs... Everything was as it should be. Then he was back at Snowdin, taking a regular stroll with Papyrus and his dad.
"Sans! Look out!"
Sans turned around as a wormhole-thing opened up. The vortex winds had already lifted him off the ground, slowly pulling him toward the hole.
"Sans!"
"Papyrus, help me!"
...."Hello? Hey man, are you okay?"....

Summary
I’m not good with summaries still- so this is a story where there’s a multiverse where they are all deities, so like deity error sans- would be of balance, destruction, codes, strings- etc you get it?
So deity reaper sans- who was deity errors lover- dies due to protecting their multiverse from something- of course deity’s of their multiverse never really die- they get reborn. However sometimes a few are unlucky enough to get reborn in a different multiverse- or without their memories until they’re older. Etc also deity’s have different names. So expect that. Pov changes to.
And when I say reborn..more like pop into existence again.

Summary
[Y/N] [L/N] is a powerful mage with a bloodline well-known throughout the ages and her family have always been celebrated. They, however, despise how their bloodline trapped monsters beneath the ground. But, that is for another day. In not being able to afford basic accommodation for university, they had to rely on an old (and terrible) friend named Bethany. For some reason, most of Bethany's skeleton mates despise [Y/N] but why is that? Apart from the fact she is a mage?
Just because she has a kindness soul, it doesn't mean she will stand for their bullshit. -
