Summary
Hey! I found this story from my old quotev account, and since so many people liked it I decided to repost it back on my AO3. For those who have been with me through the years, this is for you. I can't promise I'll ever update it again though, but for nostalgic reasons, here you go!
__
Monsters and humans are... sort of getting along. Although they technically have equal rights, things aren't exactly easy. An anti-monster gang has sprung up and wreaked havoc around the country. Naturally, a race of monsters who live off violence aren't exactly the type to shy away from a fight. Rumors are spreading about the possibility of another Monster vs. Human War, and things aren't looking good.Nevertheless, both sides are pouring into your clinic after their nightly brawls, but how does one heal a monster? It's a good thing you have a bit of magic up your sleeve, but careful! Mages aren't supposed to exist anymore.
Let's not forget that there's a certain edgy skeleton who fell for you since the day you patched him up after hours.He thought you were an actual angel, and if anyone tried to clip your wings, well, he was gonna have a great time showing them what happens when they mess with his girl.

Summary
Sans wasn't planning on getting himself a slave. There were just too many mysteries surrounding the human to just let them go. Sans was going to find every little secret of theirs if it killed him. Make no mistake, it was likely to kill him. If only the human would stop sucking up to his brother.
Or in which, the author is sick of people using slave fics to make reader a broken/submissive doll and Sans a dom butthead, so author makes their own story and gleefully tramples over some cliches.

Summary
With the magical healing powers of ketchup, Sans survives a genocide run--but the rest of his world doesn't. He sets out across the multiverse searching for a family he refuses to believe is dead, struggling to come to terms with his new life and identity and making more deadly enemies the further he goes. When a rival emerges, he's forced to choose between his past and future or risk losing both.
Complete
(Yes, this is absolute crack--but I found out there was no AU where Sans's soul is literally ketchup and decided that was a problem I had to solve. There will be family fluff, plenty of angst, a bunch of AUs, and general shenanigans. I'm treating this seriously enough that I forgot how ridiculous this was until I had to write this summary.)

Summary
𝗦𝗲𝗾𝘂𝗲𝗹 𝘁𝗼 𝗣𝗲𝗿𝗶𝘀𝗵.
𝙐𝙣𝙙𝙚𝙧𝙛𝙚𝙡𝙡 𝘼𝙐---
In a world where everything seems to be slipping through his fingers, Sans knows that the only way to survive is to do whatever it takes. With the weight of her life in his hands, he faces a terrifying truth: some things are worth losing, but he’ll do anything to ensure she isn’t one of them. In the end, the question isn’t just how far he’ll go—it’s whether he can live with the cost.
---
He remembered the conversations and the words they’d already spoken a thousand times over, the responses they’d known before they’d even asked. He remembered the fights and the endless, grueling battles where he had lost, and then won, and then lost again. The victories became hollow, empty echoes, and in the end, even the victories felt like failures.“You ever wonder,” Flowey’s voice trailed off, dropping into a hushed murmur that seemed to blend with the sound of water lapping at the stone. “If maybe she was never supposed to come back?”
The question hung in the air, heavy and unresolved. Neither of them spoke after that. They just sat there in the swamp, a place that used to be full of life, now lost to time and decay for what seemed like ages.

Summary
It has been a year since the car crash that suddenly and drastically threw Rowan’s world into disarray. She’s finally, more or less, put the pieces of her life back together. Then a rather charming skeleton family moves in across the street. Undecided pairings - though likely many in related and unrelated chapters. Admitted bias for Red and Nox. Writing what I feel like, to be honest. So going to be very character-interaction driven with lots of fluff. …And probably smut (separated out if that's the case). Inspired by, and the first chapter just steals from, the Bonely Hearts Club’s original demo. Characterizations (especially Nox and Rus) are also influenced by “popatochisp”, amongst other authors. The world is on fire and I need feels-goods (also known as dopamine) damn it.
