    Summary

    Sena watches Percy from the distance as he plays in the snow with the others. Her stare hardens, as she predicted, she can't relax. Not when his life is at stake, not when they're still looking for them.

    (Look at what you've done.)

    It's not her fault, to begin with, she was just following orders! They told her not to interfere, so she didn't.

    (You knew this was gonna happen.)

    It's not like she could just disobey a direct order from her superiors. That would lead to consequences. Terrible ones. But...

    (It's all your fault why those kids died.)

    She should've done something.

    But it's too late to regret now. She made her choice, now she has to live with it. She'll push through her guilt. And even if she could only save one child. She'll protect him, no matter the cost.

    Summary

    Life was never very kind to you, leaving you in an almost constant state of anxiety and confusion. Tangled in webs of "whys" and "how could yous." Unable to understand and jumping from one painful experience to the next just in an attempt to survive, the world silencing you in its tight grip.
    But it's one final betrayal that'll change your life completely.

    Summary


    ❝ Ninety years without slumbering,
    Tick, tock, tick, tock,
    His life seconds numbering,
    Tick, tock, tick, tock,
    It stopped short
    Never to go again,
    When the old man died ❞


    ─── •┈••✦ ❤ ✦••┈• ───


    Your life has never been easy.

    You were abandoned by your parents at a young age.
    You lost your right eye in an accident.
    Your brother passed away, leaving you to care for his son.
    Then, after several years, you died protecting the two children under your care. It was painful, but there were worse ways to go.

    And now, centuries later, you find yourself brought back to life, face-to-face with your nephew’s descendants.

    ...

    Your life was never easy, but maybe this second chance would be a nice change in direction.

    Summary

    let's cut it short.

    you are a nobody, a human in their mid twenties with a job just as dull as everything else in their mundane life.

    forgotten dreams, aching wallet, no friends, no family, no lover. nothing.

    well, except for your kitty and the measly amount of interactions you get at the clubs you always go to.

    so guess what happens when you meet a mysterious skeleton in the gas station you work at?

    why you obsess over him, of course. what else?

    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.

    Years later, 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

    Humans are complex. Bitties are also complex. You enjoy dealing with neither.

    For some elusive reason, your cat actually likes the freeloader that has been living somewhere in your kitchen. You suppose you can let the bitty stick around. The arrangement is simple after all.

    Until you meet a second freeloader and it becomes clear that everything about the situation is not simple at all.

    Red was your best friend.

    Always, forever.

    Fuck her for making everything difficult. Fuck her for making you feel otherwise.

    Summary

    Frisk dove headfirst into the Underground after spending all her childhood listening to her Mama tell her and her brother stories of the Monsters trapped below.

    What she didn’t expect once she had freed them was not only did Sans have some SOULbond with her mother (ew, that’s her Mama, Sans!) but when Sans accidently brings different versions of him and Papyrus…

    Frisk did not sign up for this! All she wanted was to free the Monsters from her Mama’s stories!


    While you had certainly seen a lot during your years, suddenly meeting your SOULmate (whom you had believed to have outlived) was like a dream come true. Monsters were getting their rights and freedom, and your relationship with Sans was steadily growing.

    ...Now throw in four alternate versions of your SOULmate and you're in for a bit of a ride.

    Especially when some unwanted familiar faces reappear.

    Summary

    “ . . . Hello?”
    You fumble, “oh! Um, Hi, my name’s Nessie, I’ve, ah, got a kid here you might know? Frisk, they said their name is. Mid-toned skin, dark brown hair, blue and pink striped top?”
    “Ah, pardon?”
    You look at the kid, whispering, “how do you know th–?”
    “Um, where are they? I’ll come right over.”
    “Oh, uh, yeah sure. We’re at a, uh, ReFuel Petrol station, around . . .” you rattle off the address, “. . . handing you over, now.” You pass the phone back to Frisk.
    Frisk eventually hangs up, and you sit with them, leaning against the register. They ask you odd questions and you notice that they seldom make any facial expressions.
    “So uh, your mum’ll be here soon. Did you run away from home?”
    They shake their head.
    “Hm.”
    They pick back up their line of questioning about whether or not you ever feel funny in the chest, and you laugh while telling them that “yeah, that’s uh, a pretty common experience for, well, humans. Probably most other animals with organs, too . . ."
