    Summary

    It all started with an overheard conversation, then an idea that was carried all the way to you.

    You had built these walls for a reason (both emotionally and physically) to keep those you loved safe.

    However, walls don’t stay up forever and can break before crashing down and that’s exactly what you feared because it meant facing everything that you kept outside.

    Summary

    It has been a few years since monsters had returned to the surface. You didn't interact with them much aside from a couple of skeleton brothers who moved into the apartment below you even though you didn't mind them. The reason for this was because of how sickly you have been your whole life and never got an answer as to why. You find yourself spending more and more time with the punny short skeleton downstairs after one day out...there's only one problem...It's the fact that your body is slowly giving out on you. Will you be able to make it through these trials that will be thrown at you as the two of you grow closer? Or will you lose all of it in the end?

    Summary

    It's your second year at the University of Ebott State, and the first year monsters since they were released from the Underground. You're the classic shy, soft-spoken, reserved girl. Your bangs hide your face, your head always in a book, and the fact that you dress like a grandma, has often made you the center of laughter and isolation. Despite that, you have a love of theater, and have a dream to eventually stand on stage and being apart of the college's theater club.

    Things start to change for you, when a new student joins your degree program, sharing almost all classes with you, who happens to be a skeleton monster, Sans. You find yourself slowly catching feelings for the skeleton.

    The only thing problem is, he already has a girlfriend.

    This can be read completely as a reader. I have not added any defining traits to the reader, but she is named for the story.

    Summary

    Parenthood was hard. That was an undeniable truth, especially for a recently divorced, financially struggling woman who has to deal with the judgment of your community. You didn’t want this to affect your baby too much, not when she was already struggling with her differences. So what do you do? You get her a friend.

    Let’s hope this goes infinitely better than how you're expecting it to.

    Summary

    You grew up together in that war-zone, his big brother watching over both of you. You watched each other's backs, never straying far from each other. They weren't supposed to protect you, you weren't supposed to live, and you certainly can't be discovered to be a human.
    But all of that doesn't seem to matter anymore when the three of you suddenly get thrusted into another universe entirely. At least.... it didn't seem to matter in the beginning.

They both have a great roommate relationship; they don’t know each other that well yet, but Sans makes her laugh.
    One day, she walks inside the apartment, wondering if she was seeing double or if there were two identical skeletons in the middle of the living room.
    Yeah, a second roommate was never mentioned on the lease.

    Summary

    You've inherited your grandmother's home and you're moving back to Ebott to start your new job at the public library. It's been a long road, but you're so close to finally having a safe place to land. Maybe someday you'll have someone to share it all with.

    This will be a self-insert reader romance between Underswap Papyrus, and eventually Underswap Sans as well.
    Expect lots of fluff, angst, friends to lovers, and found family.

    Summary

    After your mother (the last person that cared about you) passes away and you lose your job, you decide that you are going to move out of Ebott City to start a new life. On your last day in Ebbott City you make a wish into a fountain, and end up falling in. When you get out of the fountain however you find yourself face to face with a pair of skeleton brothers, and for some reason its now the 1930's???? It turns out that the Skeleton brothers are the head of the Mafia that runs your side of the city, and you now live in their district. Papyrus seems to be nice, Sans however is skeptical of you and your intentions and makes it known pretty quickly. Reader has to navigate living in a different time and figure out what their life will look like moving forward, and she wants these strange skeletons to be a part of it.

    This is a slow-burn romance where Sans doesn't want to like you, but cannot seem to stay away. Enjoy!

    Summary

    The principles of justice are chosen behind a veil of ignorance.

    He didn’t understand why he had done it. Standing in the freezing winds of Snowdin, with snowflakes swirling like silent witnesses to his hesitation, he came to the horrible realization that he never understood anything.

    But now, under a blazing sun that cast no shadows, Sans would squint at the open sky and wonder if his choice had meant anything at all—or if it was simply another link in an unbroken chain of futility. The warmth on his bones did nothing to erase the cold from his memory. And he will, yet again, remember the distant day when he made the choice.

    Snowflakes falling. Moments dissolving.

    A sky too bright to understand.

    Summary

    You fell into the Underground years ago. Being a part of society as an adult with a job to maintain was hard enough as is, but the gold-toothed skeleton and his tyrant of a brother that tormented you made shit a lot more difficult.

    See, that was hell; but now you're working for an oozing, skele-octopus creature who's got a thing for negativity. You aren't sure if this situation is better or worse, but considering you're being forced to work closely with Sans, it's probably worse.

    Summary

    9 months, 2 weeks and 3 days monsters have been adjusting to life on the surface, finding yourself caught between government red tape, a well-meaning but overbearing goat mom, and a skeleton who thinks sarcasm is a love language. New to you shenanigans are interesting's in hindsight of the bureaucratic nightmares, emotional baggage, and the world's worst sleep schedule, —

    Nope that's not just it.
    Something feels off.

    This isn’t just your day to day, not a sense of Déjà vu.
    It’s penance. And maybe, just maybe that clawing from the ash and grief, there’s something worth holding onto. Something real. But love doesn’t come easy in a world where the clock keeps resetting, and the past refuses to stay buried.
    Because some part of you knows the truth.

    You’ve done this before. And you’ve died for them every.
    Single.
    Time.
