    Summary

    Complicated. You hated that word, really - when someone told you things were ‘complicated’ you knew that they had no idea what the word really meant. And yet, it was really the only word you could use to describe your life. “Complicated.”

    Your secrets had secrets and you were towing around a mountain of personal baggage. There were very few people in your life that really understood you and you were perfectly content to never interact with anyone else unless it was absolutely necessary - because of all the things you disliked, people were at the top of that list.

    Enter one Sans the Skeleton, who is very much aware of what the word ‘complicated’ means. Looking back on it, it doesn’t surprise you at all how hard you fell for him. You didn’t believe in happy endings, but you’d be damned if you didn’t give him one - no matter how many tries it takes.

    Summary

    One year has passed since the disastrous research mission to the mythical Island in the Sky. With Ballos defeated and the Demon Crown destroyed, the Island and its inhabitants return to their peaceful existence. But when the seal on Mt. Ebott is broken and monsters begin living on the surface, the Island's true nature and relationship to monsterkind is revealed, and the secrets of human magic are uncovered.

    Author's Note: This story was originally posted on Fanfiction.net on November 2nd, 2015. Frisk is referred to in-story by male pronouns, as at the time I'd mistakenly believed Frisk to be male.

    Summary

    Monsters and humans are... sort of getting along. Although they technically have equal rights, things aren't exactly easy-peasy-lemon-squeazy. An anti-monster gang has sprung up and wreaked havoc around the country. Naturally, a race of monsters who live off of violence aren't exactly the type to shy away from a fight. Rumors are spreading about the possibility of another Monster vs. Human War, and things aren't looking good.

    Nevertheless, both sides are pouring into your clinic after their nightly brawls, but how does one heal a monster? It's a good thing you have a bit of magic up your sleeve, but careful! Mages aren't supposed to exist anymore.

    Let's not forget that there's a certain edgy skeleton who fell for you since the day you patched him up after hours. You had brains, looks, and one of the most stubborn SOULS he's ever seen. He thought you were an actual angel, and if anyone tried to clip your wings, well, he was gonna have a great time showing them what happens when they mess with his girl.

    It's only a matter of time before someone steps out of line. After all, in this world, it's kill or be killed. But one question remains: which side has the real monsters?

    Summary

    The city of Daiport has many things to brag about. It's ancient history, the beautiful mountain ranges and of course, the glistening ocean beaches that hug a good portion of the city's outskirts.

    It's also the home of the monsters that emerged from deep within Mount Ebott.

    You, having left your strict family upbringing to chase after your love for the ocean and a dream to become a professional dance choreographer, find yourself in a city quite unlike any other. But life continues much as it always has since you moved here. You work in the local surf shop, train for the biggest dance competition of your life, and spend all of your free time in the water. That is, until a chance encounter leads you to meet a monster who turns up the heat in your life.

    As for said monster? He's never met a human with hair as bright as his flames. He finds himself drawn to you for reasons he can't fully understand. So the question you both have to wonder is:

    What happens when water and fire collide?

    Summary

    You’re a librarian and part time artist. Well, artist insinuated that you sell things, which you don’t, you paint and sketch to calm your nerves. When you took up that hobby, it never occurred to you that that skill would lead to you befriending a tall and bubbly skeleton named Papyrus. Nor did you expect to feel these strange feelings towards his older, less social brother, Sans. It’s not love though. It can’t be.
    ...right?

    Summary

    Teaching at a new school was a promising prospect for you. You'd already been a teacher for two years at this point, and you were overqualified for your position. Excitement and dread settles in when you learn you may have to teach monster children.

    Not that you have a problem with that, but you're suddenly feeling like your 'overqualified' praise is misplaced. Each of your students shows up, none of them are monsters, but that doesn't mean that one student doesn't have a monster parent.

    Sans the Skeleton is Francine's father, and he seems very interested in you. You only hope that's not a bad thing, because you know who he is.... and what he's done.

    *Note: The tags can be intimidating, but note the only really bad one that applies to the Reader is probably gonna be stalking.*

    *Note 2: Updates are random. Some days I feel like writing, some days I don't. Right now updoots seem to be daily, but I'll update THIS if that is to change.

    Summary

    The town of Snowdin was always quiet and peaceful, none of the folks wanting to cause more trouble for their people since they were stuck underground already. Even so, the King had wanted to bring in a couple more sentries to the little region, and so in moved two skeletons.

    Grillby enjoyed having the Dog Squad at his bar, not only were they friendly, he was able to chat and tell Doggo about what was happening around Snowdin, also getting tips he could tell his patrons in case there were any rock slides and such to make sure they were safe. It wasn't every day that new monsters moved in, so he gave them both a warm welcome and a place to rest as with everyone else. Though he is concerned and confused about Sans. They were both nice people, sure, but Papyrus did most of the talking, while Sans just stuck to pranks.

    Soon though, the barman will figure out the brothers' stories, and promises to help them the best he can.
