    Summary

    You run a café. You mind your business. You serve caffeine to monsters, tolerate regulars, and try not to set the espresso machine on fire.

    So when “Sans” walks in acting weird—untied sneakers, hoodie with fur, telling jokes your Sans could never land—you know something’s up.

    Turns out he’s from another universe. And somehow, he’s made himself very comfortable in yours. Including on your couch. And maybe… your neck.

    You’ve already got one Sans. You don’t need another.

    Now your life is unraveling. Shortcuts are glitching. Mirrors don’t show your reflection. And the stranger who shouldn’t be here keeps looking at you like he’s known you through a thousand timelines.

    He calls himself a mistake.
    You call him everything you were afraid to want.

    Summary

    Underfell x Reader story, regular updates now.
    For the first time, a grown up human has fallen into the Underground instead of the usual younger Souls, the last Soul needed for monster-kind to escape the Underground, but, it just so happened that the human would not give up so easily.

    The story is a mix of lore (adventuring through the Underground, trying to achieve the trust route) and romance/smut. It will be feels heavy, just with a buildup to it :)

    The Reader/"You" is AFAB(assigned female at birth, so to say, a body of female sex), their gender won't be mentioned nor will their name (only nicknames), so you can think of them as yourself or whoever may come to your mind.

    -----------

    Content warnings:
    Smut and Romance (both fluff and rough), temporary Death, Violence.

    Multiple smut-scenes with the Reader and various characters from Underfell.
    Mostly slow burns, occasional fast burns will come again and again.
    Has a plot n ideas traveling along with the fun!

    Summary

    "Monsters could never artificially create their own kind. Science is not life, life is not science. The process of giving birth to offspring is only purely possible from love and the natural process of magic merging the energy of two monsters' souls. From love and magic, various hybrids can be born, giving rise to new and unknown species in the dungeon. The power of such monsters is amazing, combining several types of magic in themselves. This is how the core of a child, just born in the mother's body, will remain directly connected to its soul until the moment of birth. The young soul, which is just beginning to form, will immediately turn into a pile of dust if the procedure of separation from the mother is carried out too early. Losing its child, the monster loses a part of its own soul. Children are..."
    The Unknown closed the book without even finishing the page. The process of creating their species was too complicated. Where was the research? The facts? Not just words written down by unknown Chudovskians. Is science not life? If there had been no science, the monsters would have died after the war, destitute under the mountain. Hungry, cold, in the eternal darkness of a new life.

    Summary

    Failure. Reset.
    Failure. Reset.
    Failure. Reset.

    This time, you fall into the Underground, weeks before the last human child arrives.

    Not many monsters expected to see an adult human in the Underground after all this time... not even Sans. You definitely weren't supposed to be here.... or maybe you are? Maybe you’re 'the anomaly' that can finally stop this endless cycle of resets?

     


    Or maybe you'll just get stuck in it with the rest of them.



     

     

     

    The story is told through the second person. This was done to keep the story's POV similar to the game's POV.

    Do you think, that even the worst person, can change, if they had just tried hard enough?

    Summary

    Mature is just in case because I'm obviously a terrible person.

    Edit:The artist to the comic I mention has been told to me to be dreemurr_skelememer and thank you to piixiecv who helped me find who it was and I've dedicated this story to you just for that! I always enjoy the support and help when I can get it!

    -------------------

    This is base off the small comic where Asgore is sitting on the cliff talking to his memory of Chara where he tells of Toriel still being disgusted and avoiding him, Flowey disliking him even though Asgore knows that Flowey is Asriel/his son, and that Frisk is scared of him while not knowing how to connect as he doesn't know of the resets.

    This made me feel for him and I honestly I immediately thought he needs a girl. So, here comes (finally) a FEMALE character for our poor ex-king of the Underground!

Months have passed and Sans is hanging out with you in your apartment like usual. Deciding to make some food, you two start baking. What is the harm in baking?
