{Please remember, this is my first Undertale fanfiction. I was still new to the game and fandom itself, so I didn't have all the lines from the characters memorized by heart just yet. I'm not going back to change anything, because I don't think it'll be the same if I change it. Thanks for understanding and please enjoy the story!!!} Y/n decided to take a dare her dumb friend Carla (sorry if that's your name) told her to do. Y/n was dared to climb up Mt Ebott and back down in at least 1 day. The problem was that anyone who went up Mt Ebott, never came back. Will y/n try and complete this stupid bet, or stay and make new friends in this mysterious new place?

After sparing Toriel they met two skeletons one of them is.. Special.. His name is Sans he is the first person who has been nice to them in a long time. The other one is Papyrus the mean younger sibling. Sans and (Y/N) get closer throughout their time in the underground. Will they fall in love? How will everyone react? *Intended for a older audience!* *I do not own any characters in Underfell or Horrortale* *I do not own any music or pictures used in this book.* *Y/N is your character!

Thank you.

(Y/N) and Sans have been best friends for who knows how long. Nothing could ever ruin their friendship... or could there be something? The human and monster war breaks out and the monsters are trapped underground, making Sans and (Y/N)'s friendship come apart. Years later, (Y/N) decides to hike up Mt. Ebott, where the monsters got trapped under, and falls down a hole. They end up seeing everyone they remember from when they were younger, but will THEY remember (Y/N). If they do, will they even protect her from the evil in the Underground, or will they let her die?

(Y/N)'s parents abuse her since she was the mistake in the family. MONSTERS has been released from the underground by Frisk. Frisk And (Y/N) go to the same college (Frisk is older in this). Little does (Y/N) know , she met someone who who cares for her. What will (Y/N) do??

After Ethan (Frisk's older brother) broke the barrier and set everyone free, they went on a huge trip around the world to spend more time together. Frisk had no time at all to talk to her friends and to top it all off she had lost her phone on the first plane ride. Her and Ethan decide it's a good idea to go back to where all of her friends live after over a year of traveling. Frisk was so excited to see her friends again. Especially Sans. Before she left they shared their first kiss and she said that they could work out a long distance relationship but it didn't work out since she had no way of talking to him. She just hopes that they can become closer after not seeing him for what felt like forever. Most of this story will be in Frisk's POV but I might change it around sometimes. Frisk and Sans are about the same age and Frisk is a girl. Chara will be in this sometimes but she's not a genocidal maniac. Also Asriel is in this as well and Flowey was never a thing. One more thing. This will have some curses in it so if you don't like that, don't read it. Anyways, enjoy!

Many years ago there was a war between humans and monsters. Although monsters had inborn magic on their side they were sentenced to live in the Underground, seperated from the surface by a barrier of human souls. The monsters have broken through the barrier and now wish to live among us. Duska watches from her room as a reporter interviews King Asgore on the TV, wondering how life will change for her. Now she lives with two monsters. How much will her life change? Can she reveal her deepest secret to them? Will she find more about herself? Will she fall in love? (Undertale does not belong to me, only Duska does. The songs linked belong to their respectful owners and so does the art. There will be swearing and strong themes. Please enjoy!) (Will upload a new chapter every Australian Tuesday and Thursday.)

~'Disclaimer: This story has a lot of profanity and covers some very very intense or touchy subjects that may disturb some readers. You have been warned.'~ ((Unedited)) After Chara fell into the Underground, they met Asriel a monster inhabitant of the Underground. Soon after that, Chara joins a new family, but their ambition to keep everyone happy goes a little overboard and Chara is flung into a reality of destruction and hopeless wonder. Then many long years later they meet the beloved Frisk, who fell into the Underground, similar to themselves. Eventually everything Chara thought they knew correctly is turned upside down and they as a person are changed forever. ~'The game Undertale belongs to Toby Fox and some of the dialogue is ripped straight from the game itself, too.'~

"I couldn't hold my breath for so long, my vision was all blurry, and my hearing muffled. I heard a loud splash and saw something red and flowing. I felt something pulling me out and a sharp pain on my right ankle. It felt like a cut to me. I could barely focus on the pain since I was losing consciousness. Everything slowly went black as I heard a familiar voice calling out my name." Alphys and Undyne are strangers to each other. After sorting out Mettaton's problem, they get stuck in a dorm together. It may take a few months for them to bond, but a school dance and summer break can really bring them close. So will they? Will they be together in the end?
