    Summary

    Your year was going pretty great for you, despite some hiccups in the beginning. You graduated college, got accepted into dental hygiene school, bought a new car, adopted a kitten, and your relationship with your high school sweetheart was even better than before! Things were looking up for you, and you were STOKED for your future. Then it all came crashing down on you (quite literally) when you were in a car wreck. Luckily, you were in good hands, er, claws of a little lizard doctor. You two clicked pretty well, and that’s when things really took a turn.

    You met a certain goofy [handsome] skeleton.

    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.

    Summary

    Moving from a backwater town to a city bustling with human and monsterfolk alike, some things begin to change both for the better and the worse. What was left behind comes back to bite at you in the most unexpected times, current progress being put in danger as a result. It's hard to move on, though it's equally difficult trying to stay loyal to what you believe is right.

    With an adoptive seven-year-old son and the remnants of a recent divorce in your hands, your goal is to move on and adjust to life with monsters, these becoming an important part of your life -- one of them in particular reigniting the spark you thought gone with your ex spouse.

    Summary

    Basically it's a lot of chapters of Reader/Sans angst and fluff- there's a bit of a plot but I kind of discover it as I go. Inspired by Undertale, other creators, and my need to shove Sans through a meat grinder and then give him the happy ending he deserves-even if it takes him a while. Please don't judge- I don't edit too much and so my past/present tenses get confused often. Thanks!
    EDIT: After getting farther through this, I'm realizing I do kind of have my own overarching plot! If you leave kudos, I love to go check out your work. So much fun, thank you guys!

    Summary

    You are a twenty-something university student, alone on Christmas because of your own choices and now the strange shape in your dreams is meeting up with your day-time hallucinations and trying to convince you that you've got just the dumb, bright red soul they need to open the underground? Sure, I guess that might as well happen.

     

    This fic is very self-indulgent, you're gonna have to suspend disbelief hardcore when we get into the thick of it. Slower updating speed but never dead!

    Summary

    You gently pushed the door and here you were, outside of the ruins. The first thing to hit you was the cold, then the realization that you just left the only safe place available to you. The second thing to hit you was that wow, maybe it would be warmer if you weren't wearing just some t-shirt and old jeans. The third thing and the last, was that now you were aware of holes in your sneakers. It felt like it was going to be a great day.

    Summary

    He had been having dreams of the same cute little drunk human for almost a year now. They were vivid and she was fun to talk to, and he was convinced that his 'dreams' were accidental manifestations of her magic. Magic she didn't even realize she had. But that magic may have just pulled her into a world of danger.

    Summary

    You’re just an average, happy human, going about life, trying to forge your way in the world. Fortunately, you’ve landed a nice job that pays well, you’re steadily and reliably working your way out of the debt you gained from moving to the city, and you found a great apartment (with a chill roommate, Sans, a polite skeleton monster with puns up his sleeve and an indecipherable gaze) for surprisingly little rent.

    Everything’s fine.

    And then, without warning, two more skeletons seem to show up out of nowhere at your and Sans’s shared apartment. The first to appear is Red, a hot-blooded, sharp-grinned alcoholic who isn’t shy to share his less than savoury intentions with you, with crude gestures and pick-up lines galore.

    ... And the second is a tall, broad, but quiet skeleton who immediately goes by the pseudonym Skull, sporting a huge crack in his head and a single, engorged red iris, that never seems to stop staring at you.

    You’re not sure why both of them won’t leave you alone, or why Sans seems so desperate to stop them from interacting with you... But hey, what harm could come from it?
