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!

You were a kind human who has a brother named Frisk. You and Frisk always get along until both of you climbed up a mountain. very curious if the legend was true or not. "(Y/N)!! Help!!" You looked towards where Frisk was. He fell into a hole as you jumped in to help him. Both of you landed on the ground with flowers catching your fall. Both of you were in pain as both of you heard foot steps. "A-Are you okay?"

You've been doing the same True Pacifist / Pacifist Run over and over in a place called the "Underground". Though you like the Underground, you can't help but feel weary.. Every time you [SAVE] everyone, the World just..[RESETS]... And with that, you're back at the beginning again. You just want to go home... Why won't this "Underground" let you leave? ... Well, if you can't leave... Something 'new' should happen sooner or later, right..? (You hope that something exciting or different will happen in the Underground.) (You are filled with DETERMINATION.) --- ;) ~~~Disclaimer: I don't own those (MULTIPLE) pictures used in the Cover. I just mixed them up for a spicy cover. ( ͡° ͜ʖ ͡°) Mash-up covers are the best. ;') (I spent up to 3 hrs mixing stuff around + editing + adding light and shadows...*Dies*) If you have a problem with the Cover, I'll change it.

All the world, just hated kind people... they threated them as nothing and put them aside. That even happened in the underworld... They saw them as a sickness, what they don't know is that sicknesses spread... (Cover made by me :3)

(Y/n) (l/n) has a YouTube channel of about 26 subscribers. Ironically, her best friends are Jackspeticseye, Markiplier, Pewdiepie, Wade, Yami, Ken, and Bob. No wonder she would fall down a freaking mountain! (Caution: do not approach if you cannot handle swearing, insane people, you're good to go! Also, UF MTT is mine! Just made this story because he needs love)

I'm here with a new book based on Undertale, Underswap, and Storyshift. These three main characters are most commonly known as The Bad Time Trio. This book is mostly about their adventures, hardships, and challenges that they're going to face. Hopefully all of you will enjoy reading this book even if you're not a fan of Undertale or is still a fan of this game. [NOTE] I DO NOT OWN ANY OF THE THREE ABOVE MENTIONED AUS. THEY ALL BELONG TO THEIR RIGHTFUL OWNERS. I ALSO DO NOT OWN ANY OF THE PICTURES THAT I WILL SHOW IN THIS BOOK NOR THE VIDEOS. EVERYTHING HERE BELONGS TO THEIR RIGHTFUL OWNERS.
