You go on a hiking trip with your mom and brother and somehow you get separated from them. Finding the way to the Underground, your life is about to change once you meet a very special skeleton. Along the way, you continue to have this... odd feeling. Like you're constantly remembering something. But this is your first time here! How is this possible...? (I know Papyrus is pretty shy himself, but being super shy myself, I kinda wanted to try this and see how it goes and where the story leads. Any and all feelings towards different characters that are or will be mentioned are my personal feelings towards them. It's perfectly fine if you disagree with me, but I'd appreciate it if you all would be kind and respectful of mine and other's opinions. If you respect me, I'll respect you. Simple as that. Oh! One more thing; the reader is female. Anyway, please enjoy!)

((FINISHED)) Error woke up in the antivoid, the pale light the only thing for miles. He had a feeling about today, not that it would be a good day in particular, but just one of those that would stand out. As if it were almost like the beginning of a nightmare for him...

You died. Again. But, when you woke up... You were back at the beginning. You didn't reset... but something was off. Flowey seemed skittish, frightened even. He was KIND. The people you knew, you once held dear... CHANGED. The entire underground was different... Dark. Nobody seemed to recognize you, but a part of them still remained. Someone who just wanted a friend, to be looked up to, respected... And another who just wanted hope-who was tired of this game... You're left with two choices: Will you kill to survive, or will you die befriending them all over again? Authors Note: This is in the AU Underfell. I recommend looking into it, it's simply amazing to me! Long story short, the "you" mentioned there is Frisk but it was a good description for the AU I found once. This is basically, somewhere the save file got corrupted, and now everything is reversed except Frisk. Hope you enjoy! Disclaimer: I do not own Undertale.

After Frisk goes missing, Caitlin, Frisk's twin sister goes looking for her in the the last place she saw her. MT Ebott, the mountain of dark legends, she finds a necklace that belonged to Frisk on the ground. Just like Frisk, Caitlin tripped and fell into the Underground. Caitlin finds things she never knew existed.

Warning! There is a chance that there will be spoilers for the pacifist run of undertale. I recommend finishing that before reading this. There won't be any spoilers for the no mercy run, so don't worry about that! Also, don't worry about anything NSFW/lemon if that's not what you're into-there won't be any of that here. You're a human that's fallen down into the underground. You've decided that you'll stay instead of going home after fighting Asgore and sparing him. Now, you had made some great friendships while in the underground-but one of those friends in particular was one you'd like to be a little more than friends with... Aaaa an X reader fic! I haven't done one of these before, but I hope you still like it!

In the Undertale universe, a different human child falls down into the underground. Even though she is very young she will have to find her way home or stay there forever. ----- Big thanks to my friend from school who helped me out a bit.

My name is (y/n) (l/n) and I have no idea how I came here to the underground. No, really, I just woke up in a patch of flowers... Anyways, I've heard legends about monsters that live underground... They exist. But something about them is just... Odd... I've heard from monsters that the king is obsessed with us humans and well... I'm not really sure how to feel about that... In this book, you are going to read my adventures from when I travelled through the terrifying city's full of monsters who... All... Love ME?!?
