    Summary

    This f**ker, Sans, was it? Thinks he can just get away with disrespecting your best friend, does he? Oh, f**k no. If he wants to play it big, you'll show him who's the biggest d**k around.

    ------------------

    After all the resets, Sans was finally on the surface. You think a little LV is going to scare him? Okay...maybe it's not a little... But he's been through Underhell and back, he'll run you out of his home if it's the last thing he'll do.

    Summary

    Monsters have been above ground for five years. You're in college in Ebott City, going against your mother's wishes to be a zoologist. But it seemed your monsterphobic roommate is kicking you out. Luckily, it looks like your buddy Sans has a solution.
    Move in with him and his brother. Plus, all of their cousins who just so happen to look like the pair of them!

    I mean, what could possibly go wrong, right?

    Oh boy.

    Summary

    A night out with your roommates' sorority sounded like a good way to wind down from exams season, but your good intentions to keep from ruining someone's nice carpet have you end up in the middle of the forest. In the middle of the night. Very, very drunk.

    Good thing you found a random house to sidle up to and ask to use their phone. Less of a good thing that the skeleton monster that lives in it is only placated by your sloppy jokes.

    -

    Eventually going to culminate in a "Six Skeletons" sort of set-up, but you don't get off as easy by knowing Classic Sans first.

    Summary

    Based off undertale characters, but does not have the usual monster-rise-to-power political plot.

    Our 23 year old Female MC is an optimist who does her best to care for those around her.

    She owns a small cafe, so how does she manage to afford her baby blue sports car and motorbike?
    She also has a little pet rabbit called Kiwi, and an indecipherable train of thought.

    Sans is hurt by all he's gone through during the time underground, but MC won't let him drown.
    He's smart, OP, and who knew he'd have a jealous streak in him?

    Who is this girl and why is she so crazy? More importantly, why does he love it?

    There is plot, but mostly fluff. Because I love fluff.
    Prepare for smiles and awwwwwwws.

    Summary

    Your father is a poor man, who has a plan that might make him rich. All he wants is money and to make his small family happy, so he hopes the Aster family is able to make that happen somehow.

    But you fucked all of that up for him because of what happened at that party. Or at least, that’s what you thought at first.

    Little did you know, one of the members took a liking to you… he isn’t exactly happy about that. He doesn’t like attachments. He struggles to give you everything. Struggles to feel things in general, and usually locks his heart away.

     

    You just had to open the cage.

    Summary

    I write tiny fluff for myself when I get stressed out or down on my tumblr... And some people have requested it to be posted on Ao3 too, Haha ^^ (I'll put the links to the original post in the end notes! I'll update whenever I do make em, there's no schedule for this one!)
    I will be mostly still be posting them on tumblr, but this is a way you can find them all at once. Most of them are unrelated except of a tiny series I call "6 Skeletons and the Crasher" that has no chronological order of tiny snippets of reader's life in one house with 6 skeletons.
    Summaries for each of the snippets will be put in the notes!
    I hope you enjoy the fluff!
