    Summary

    As a human that's recently moved to the Underground, you've been adjusting to a very different life. You've been treated politely enough, but routines aren't what you're used to, and you don't know anyone closely yet...until one night, you decide to go to a comedy show, and meet someone that changes everything.

    Summary

    It was twelve AM on a friday night- or saturday morning. You'd just finished working a double at the bar; tired and achy as all hell, all you wanted was get home and get off your feet for the first time in fifteen damn hours. You were almost home, just one block off from your apartment; maybe if you'd left work just a few minutes earlier or later, you could have avoided what happened next...

    But you didn't.

    You never did make it to your apartment that night.

    Summary

    When you wake up some where you're not supposed to be, with a bunch of creatures that aren't supposed to exist, what is one supposed to do? Sit down and panic should be the first answer, but, sometimes, you just don't have time for it.

    Summary

    Once long ago, humans and monsters lived alongside one another. During this time it was an age of unparalleled magic and strength in the two sides.

    However, the great war happened, and with the absence of monsters mages slowly died out. After all, humans are not inherently magical. With no more magic to keep the blood lines going, magic is all but a fantasy in the humans of today. That is, until an eccentric billionaire decides the mages need a come back.
    Looks like you and a few others are just the right subjects to get the ball rolling.

     Oh right! There is some swearing in here.

    *WARNING* Some people are very sensitive to kidnapping/abduction themes. While I assure you, I probably won't go too dark, it is a bit... muddy in here. Tread lightly.

    Summary

    IT'S OCTOBER, GUYS! YOU KNOW WHAT THIS MEANS FOR AUTHORS!

    You know how this goes, right? Whole bunch of reader inserts about special fun times with your favorites. And I have no regrets posting this, whatsoever.

    If you are under the age of 18, I would prefer you not read this. Period. If you do, I don't wanna know.

    So...shall we start the Sin Train?

    Summary

    You went to the bookstore one day to buy some manga.

    You got a whole lot more than you bargained for.

    You end up somehow saving the Royal Scientist's life, and her fiancée can't thank you enough for it.

    So that's how you find yourself surrounded by people who love you for who you are and don't want you to change.

    But what's up with these strange dreams you're having? And, why does a certain punny skeleton get so spooked at the number 17? And...who is that tall skeleton with cracks in his face that you keep seeing in your dreams? Did the ambassador of monsters just join your swim team? Can this summary get more cliché?

    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

    You're a terrible person.
    Which was pretty self-explanatory in it of itself, but nonetheless.
    Your descent into human tragedy had been anything but an overnight change, but, you know. Things happened, and the culmination of all your questionable life choices had led you to become the person you were now; a sarcastic, twenty-something-year-old nihilist with bleak prospects boarding on the line of alcoholism.

    So when you wake up after a night at a bar in a jacket that doesn't belong to you and a throbbing, all-consuming hangover, you're not exactly surprised. But when a certain red-eyed skeleton with a wolfish grin and anger management issues decides to insert himself into your trainwreck of a life, well. You aren't having it.

    Unfortunately, he's not taking no for an answer.

    Summary

    You watched him unwrap his lunch, pouting.

    “C’mon, man. Not even a bite?” He started eating and you groaned dramatically. “I’m starving. I’m dying right in front of you. You’re killing me, Papyrus.”

    “good,” he muttered around a mouthful of food.

    “Wow, rude. I have no idea why we’re friends.” You sighed, eyeing the glittery burrito.

    “because you like to mooch off of me,” Papyrus snorted. He finished it off, cracking a grin when you whined in distress. “besides, y’know i only eat this because m’lord made it. he can always tell when i give it away. i’ll get ya something from a food truck later.”

    You nearly cried. “Thank you! I swear, I’ll pay you back when I’m a millionaire.”

    “so, never?”

    “I’ll try.”

    Papyrus shook his head with a grin, reaching out to pat your head. “guess that’s better than nothing.”

    You beamed, soaking up the affection. Papyrus always had your back.

    But… you were still so hungry. You worried that soon, food trucks wouldn’t be enough. Nothing would.

    Summary

    The final continuation of my series, "Everything Is Going To Be Okay."

    You should probably read it for this to make sense.
    You don't have to.
    You do you, I guess.

    Co-Co grows to be a part of your chaos-magnet home, and a part of the Underground as well. All of your friends used to be out for human kids- but they would die for this one. And for you. Even a few alternate universes come to your aid as the world crashes around your ears...will it be worth it in the end?

    *WARNING* I DO NOT PLAN A HAPPY ENDING FOR THIS SERIES.
    IF YOU DON'T LIKE IT
    THEN DON'T READ IT!
    OR IF YOU DON'T LIKE IT, READ IT ANYWAY BECAUSE YOU CAN'T ESCAPE THE VOID OF MY LITERATURE.

    Summary

    Your name is unimportant. Your job is nonexistent, really. And your (ex)roommate just kicked you out in the middle of a surprisingly cold November night. But whatever. You don't care. You'll be fine.

    Keep telling yourself that as you freeze to death, idiot.

    But you'll be fine, for one reason! Two, actually. Two people - monsters really - who just so happen to have the same names as some fonts you know of? You stay with them instead, just to get back on your feet, and a single question rises to your mind.

    What the hell is keeping you here?

    Summary

    You never would have guessed that a random act of kindness on your part would kick start a skeleton's obsessive tendencies. If you had known it'd get you kidnapped, you would have run away screaming - soulmate or not.

    Yet here you are. After all: "no good deed goes unpunished".

     

    [Thought I'd try out some drabbles to get me back into the swing of posting while I work on completing "Déjà Brew" and "The Red Thread of Fate"! Each chapter will have 10 drabbles and each drabble should have about 100 words, though it varies depending on what program it's pasted in ಠ_ಠ]
