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
You need to stop staring at him.
You could spend an eternity just watching him sway his hips along to some overly cheerful pop-song bubbling from his phone, (especially because Stretch is gone for the weekend working on something with Undyne, which means he can’t tease you for getting distracted by the cooler Serif,) but you know that eventually Val will catch you ogling him. Forcing your attention elsewhere, you help out by finding a pot, using the stepstool in front of the sink to be able to reach for the cold handle.
(or, in which the reader falls victim to one of Stretch's traps set behind for his brother, and it leads to some shenanigans with your boyfriend.)

Summary
As a person, falling in love wasn't on the top of your priority list. If it happened, it happened, but you weren't all too bitter if it didn't. Maybe whatever social higher power wasn't too happy about that, so it just had to partner you up with some nerdy idiot who flew too close to the sun and ripped a self-shaped hole in the middle of reality itself.
And then you also fell in love with his brother. Too bad that you aren't too up for polygamy.

Summary
It’s fun being dead.
Or undead, rather, as your sister likes to correct you. Your dear sister is the kind of person who took her dark arts very seriously. Or, her necromancy, rather. You’ll be the first to admit, you don’t know a lot about her school of magic. She doesn’t know much about yours either, but it’s always enjoyable to discuss magical theory with her. She says it’s not her specialty, but she tends to under credit herself.

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.
