(I don't own the Game Undertale or the AU, Underswap nor Undertale Or anything else I only own the anime pictures) enjoy this story :3 also I'm to lazy to make puzzles

Y/N, a girl who is bullied, accidentally falls down a mysterious hole, spooked by an unknown force. Meanwhile, she meets a timid flower, who leads her through the dark underground. Brave and tough, she expects herself to survive the odd challenges of the underground; but how far will her courage bring her? Will she ever get home? Will a certain skeleton in boots make her want to stay? Spoilers for just Undertale in general. There will be some (eventual) fluff, just a warning (づ⌣ω⌣)づ I do NOT own any content besides the story. All characters and images belong to the original artists and creators. Thank you.

UF. Papyrus X Reader Broken and Bloody you arrived in the underground.............. It's pretty much the same, expect something I have yet to figure out. Yeah. Read I guess. (My first undertale fanfic to sorry ahead of time for suckiness.)

Warning: If you don't know what a Yandere is, it is someone with a love obsess and would do anything for the crush's love. Usually they harm those who loves the crush too and pretends to eliminate them. BTW in this story Chara and Frisk are males. And Chara is also a Yandere. This is totally inspired in Yandere Simulator, so credits to YandereDev. Papyrus isn't the person with the most attention, because he has his own "rivals".

You have Fallen into the underground. You made it Past a murderer Goat called Torial. You seen two skeletons One Tall Called Papyrus and one small called Sans. Now you are heading to WaterFall When Somthing Happens and makes you stop.

You are a monster returning to the underground before the war you where mistaken for a human so the humans took you away from your father and once they discovered what you really where they abused, raped, and cut you. Also you have cat ears and a cat tail!

You've been best friends with Papyrus for years now, but you never thought he liked you in that way. And you never knew how far we would go to get you to love him. Will you love him back?!

EDIT: READER AND PAPYRUS ARE BOTH IN THEIR TEENS!! WARNING: BOOK CONTAINS SWEARING/CUSSING AND VIOLENCE Just before she passed away, my grandmother told me about the monsters who lived under Mount Ebott. My mother hated everyone. My father died in the war of the monsters. My grandmother decided to whisper to me: "Promise me, You will find, A better family. One who will love you, No matter their duties. I will love you too, I will be watching you. No matter your choice, Let me hear your happy voice." So that's what I did. Her words went through my head as I climbed the mountain, hoping that a monster could help me. - "Sans flinched as the shouting downstairs grew louder. The ropes around my wrist seemed to grow tighter as I struggled, hoping to break free from the monster stomping up the stairs angrily. As Sans stepped back, his door was smashed open. I took one long look at the figure standing there and instantly knew: this is why I am here." - (SLOW STORY! MANY SLOW CHAPTERS BECAUSE OF DETAILS)(COVER ART NOT BY ME!)

"Well, nothing can be 'great', now can it?" (Contains some foul language)

You are a run away from your home. Your drunken mother hasn't even tried to find you. You live in a small box in an alley way in which you barely can fit into to hide from the rain. One day you come across one of the monsters from the place known as the Underground. Could it get any worse?
