Summary
Monsters are free, and Frisk is safe and sound at home.
It feels like fairy tales are real, though a rough break-up after eight years of marriage quickly sobers that thinking.
With the break-up follows a proposal straight out of a steamy novel: share a room with a man you've just met, while you get back on your feet and work on the process of finding a new place to move into.
Turns out, the guy who smells like grease and beer from how often he visits Grillby's is a lot less romantic than you would think.
And it's precisely living together what gets you to know all the icky things about him.
Until you end up falling for him with each nice little thing he does, and suddenly...
It feels like all those icky things start to matter less and less.
More so, when things take a sharp turn and you're in the middle of a gang fight, helping him however you can despite not knowing what you're signing up for.
Overlooking details like bloody clothing, chipped teeth, and reports of missing people on the telly make seeing him drinking straight from the milk carton a much more tolerable offense.

Summary
Once known as one of the best scientists of the Royal Guard, Sans lives on logic and logic only.
He's rejected the idea of soulmates being real, too stubborn to picture it as something remotely plausible.
So, when he starts to gain glimpses of a thin red string tied to his only other human friend besides Frisk, Sans ignores that for an entire year.
Unable to accept his new reality, he drinks himself to near intoxication, and then his drunken self wanders into Grillby's, searching for the woman responsible for making him feel this way.

Summary
Cherry Sweet is a rather unconventional performer at a club like 'The Velvet Crop' with her thick thighs and plush stomach, but she does well enough for herself. The patrons enjoy a bit of variety, but what will she do when she attracts the attention of a monster--and a mob boss monster at that?
Featuring a 1920's vibe with music from the 20's-60's, a meet-not-so-cute developing into a partnership, and a spitfire, plus-sized FMC. I hope you all enjoy!

Summary
In one multiverse, there is chaos.
A Creator unknowingly tips the balance, and a Destroyer writhes in pure pain.
The multiverse is governed by Fate and observed by Destiny, Karma, Light, Dark, Death, and Life.
But what no one realizes is—they are not the first.
Fate once created another multiverse… then abandoned it. Destiny, however, did not. Destiny gave it freedom and continued to watch over it.
When the Destroyer is cast into the Void and crashes into that forgotten multiverse, they take him in as their own.
And there, two beings—a skeleton and a human sorcerer—fall in love with him.

Summary
A Mafiatale inspired Story, Inspired by Staringback's Sooner or Later You're Gonna Be Mine
1920's, a time of flappers, broadcast radio and jazz. At least that's just the glamorous side of the spectrum, on the other end is mobsters, inequality and the ever growing poverty rate. 1928- Is where this story begins, Mercy City, or Sin City is what the majority of the city's residence tends to call it. One resident in particular for sure knows first hand that Mercy City definitely lives up to it's reputation as the most violent city in all the county.... Hell, the world even.Meet Frisk, just one of many of the working Joes that tries to scrape on by from paycheck to paycheck. Working day in and day out with honest jobs that hardly pay anything respectable at all, but he's not worried about that. At least, not until a certain encounter, that figured out his deadly secret, says otherwise.

Summary
“i just wanted ta offer ya one piece of advice, then i’ll get out of your hair.” Frisk took a step back, eyes wide, when the little lights in sans’s eyes went out once again. sans took a step to match hers and one more to put himself right in front of her. The color in Frisk's face drained away in fear.
“if you hurt grillby or cause him harm in any way…..Y o u ‘ l l b e d e a d w h e r e y o u s t a n d.” He said slowly, in a deep, cold voice. The lights in his eyes reignited and he took a step back, “understand?”Never draw attention to yourself. That was the number one rule Frisk had lived by these past few years. It kept her hidden. It kept her safe. So why, out of everyone on this planet, is a high ranking member of the mob suddenly interested in her? She can’t seem to shake him off, no matter how plain she makes herself out to be. Will his interest bring her into the searchlights?
