Summary
You're a grad student at a house party. How many skeletons are you running into there? At least one you didn't expect.
(This explains nothing. Please read if you like Sans/Reader romance slice of life with plot, character relationships, fluff and eventual smut. Underfell headcannon is being used.)
(Time for a second note to reemphasize PLOT. Drowning in plot. Plot for days. Send help.)

Summary
Sans was starting to feel like there was a little too much on his plate.
With everything going on–the monsters living on the surface now, the angry backlash from the human city, some weird creepy dreams he wasn’t going to acknowledge anytime soon, and trying to work on something that would stop the resets entirely, all the while he still kept up with supporting his brother in his work of being a monster mascot–Sans would say he was completely booked. In fact, he was basically a full library at this point.
Oh, and then there were the skeletons that looked disturbingly like him and his brother that started showing up out of nowhere. That was happening too.
And they sure as hell were not as friendly as Sans would’ve liked.
Or,
Sans and the other monsters are on the surface now, when different timelines suddenly begin converging into his and start spewing out alternative versions of him and his brother. The world was apparently ending, but, hey, what else was new?

Summary
Sometimes life throws you a curveball. For you, your curveball was going to bed looking like a human, and waking up looking like a monster.
A skeleton monster to be precise.
With the barrier breaking, a large surge of magic descended on the town you live in, and transformed you overnight. Unsure what to do with you, and the others changed, you're ushered into a facility until a monster with similar magic can take you to teach you how to wield the now uncontrollable magic you've been given. After waiting in this place for four years, you'd given up hope that anyone would ever want to take you.
What a surprise for you when you find out that someone does. A lot of someones.

Summary
Taking a break from college to focus on making money seems to be a pattern in many lives.
One semester. Just one is what was promised. However, after the summer semester had concluded with no classes, finding the drive to go back was too difficult, especially when money was still tight. With the eventual deterioration of an ancient car, savings were emptied to find a used car that would suffice. One job just did not cut it anymore with expensive car payments looming every month.Finding a new job as a delivery driver for a pizza place in the 'newer' monster town, you find yourself at the doorsteps of most of the monsters who had emerged merely 2 years ago. The monsters' first emergence was met with heavy backlash, but as the 2 years had gone, most of that stigmatization stayed within households while the monsters were promised suitable living. The monster area paid the best hourly wages in the state, all while being within a reasonable distance. While some customers were gruff and crude, the people you meet prove to be more three-dimensional than most. However, you have your gripes with one particular pair of boneheaded skeletons.
