    Summary

    Sans/Reader fluff and angst! And angsty fluff! And romantic fluff!
    Every chapter is its own story!
    Prepare or tears and happiness and other stuff!
    You can read this apart from the first work in this series, but I carry a lot of stuff over from that one, so I'd read it first to make sense of some of this stuff. I really only started a new work because I was worried the other one was getting too long.
    Thank you to everyone who supported me and left kudos on my last work! These are basically 1/4 canon compliant, because most of it is me talking about ships and stuff.
    Anyhoo, you just got back from Colorado, and immediately things start getting weird. How will you and Sans handle it?

    Summary

    Why is it so cold when you're in the sun? Why does food not satisfy? What douses your good days in spirals of thoughts that you don't control? Why do you feel so hopeless when you're doing fine?
    The answer may surprise you.

    Soulmates? On my PC? It's more likely than you think!
    In all honesty, I haven't the foggiest on what I'm doing, but I hope it's good.

    Summary

    All you had wanted to do was explore the empty Undergrounds a few months after monsters emerged. And where had that gotten you? Kidnapped and locked in some psycho skeleton's basement.

    Luckily for you, you're "rescued" by other skeletons. Who all more or less look the same. Except you still can't go home, because you know about too much of something you're not suppose to know anything about.

    So now you're stuck in the Undergrounds with a creepy murderous looking Axe, a perverted Red who can't keep his hands to himself, a loud and obnoxious brat named Blackberry, a dog like Pup that won't control his instincts, and a carefree Sans.

    At least Blueberry is normal.... r-right?

    Summary

    As soon as Sans had fired the bullet, he felt the world slow down, his vision taking in every detail in that frozen moment as he felt the slow droop of his cigar begin to fall and the heavy smoke taste stick like glue in his mouth.

    The drawn out distant clink of bullet cases tinkling on the floor echoed around him, the muzzle flashes stuck mid-fire, the beads of sweat on his men’s faces shining with a sickly yellow glow as bullets hung in the air moving imperceptibly slow. Cards, poker chips and money were thrown up in the air as the trails of wood chips and dust flung everything aside. Tables were fixed in place as people cowered behind them as they flipped them up in a panic, fear and screams stopped in the still shot of time.

    Except one person.

    Her.

    A devil in a red dress.

    Summary

    If there was one thing you HATED in this world, it was dancing. A complete an utter waste of time which ended in bitterness and depression. Why had you even bothered to try such a thing? And it's not like you needed it anyway, you didn't feel an itch in your muscles nor the tapping of your feet to the radio that plays dimly from another apartment. You just want to get through university and get out from...whatever this was.

    Of course an entire mountain decides to explode with dancing monsters of all shapes and sizes. Dammit.

     

    =================

    Stars, Sans really couldn't get any lazier than he already was. With monsters pirouetting left and right of him, jamming it down the streets and waltzing all over his daily life, he really couldn't stand the sound of moving feet. All he wants is peace and quiet, to lose himself in the grey monotony of ketchup, sleep and tv. Even University is a huge chore and he barely scrapes the attendance on his courses.

    And somehow, even in all his seclusion, he ends up meeting you.

    Where you both ask yourselves the same question every day.

    Summary

    Constantly, the same thing over and over, no matter what Frisk did, no matter what Chara tried. They were becoming numb to it. And so, they laid there, starting up at the opening they fell through, refusing to even start. That's when they heard you call out to them.

    Summary

    His skull shines from the sun as he looks through the glass at you, his face wearing a bright but also lazy smile. He gives a small wave, which you returned politely before settling back into the pile of pillows.

    He seems to take the hint and turns around, engaging in conversation with the rabbit monster. While his back is turned you take a closer look at him.

    He wears a blue jacket with a grey hoodie, black shorts that have a white stripe down the sides and pink bunny slippers. His stance screams lazy and uncaring of the world around him. Cool.

    You haven't even said a word to him, but you already hope he sticks around.

    Summary

    Monsters have arisen from the depths of Mount Ebbot, from a horrendous place you now know as Underfell. The monsters you have the pleasure of meeting may be rough and stand-offish at first, but once you take the time to know them, you're like one of the (albeit dysfunctional) family!

    Summary

    'This is perhaps the closest your ever been to a monster. You never could imagine just how overpowering their presence could be – it’s threatening, smothering, like an unbearable heat that saps your energy. You swallow when the fear sinks in, the realisation that you're in the same room as one of the most dangerous, most powerful creatures in the whole building.
    You only register the large, black boots halting in front of you at the last second. Your head is forced up, and you are staring into the face of Death.'

     

    The monsters have taken Ebott after the Barrier beneath Mt. Ebott shattered without warning. The world you knew is gradually being forgotten by those within its borders, remoulded to suit your new masters who wield powers you cannot even hope to possess.

    But you cannot give up just yet – you have to persevere.

    Summary

    You're just a human, trying to live your life, trying to forget your past and move on. He's some weird skeleton who won't leave you alone and seems to think you belong together. You're NOT interested. Surely this can't end well.

    Something I used as a tool against writer's block. A bit of a vent piece. Probably will update sporadically.
