[2nd book] ((COMPLETED)) {Undertale AU - Underfell} [WARNING:ENDING AND PLOT IS VERY CRINGEY] "Long ago, two races ruled the earth, the Humans and the Monsters. One day, war broke between the two races. Many have fallen to serve their kind. Years later, the humans were victorious. With their magic, seven of their strongest wizards sealed all the monsters underground with a magical barrier. Only a human soul could pass. Mt. Ebott 201X, they say those daring enough to climb up the mountain.... never return. " "Leave them, Y/N! Run! " ___________________________________________ I'm a Undertale addict. I freaking love the story line and characters! One of my favorite AUs is Underfell so I'm finally making an X reader. Also, if there are wrong spelling or grammar, please tell me. I'm using GoKeyboard. Enjoy my Crappy 2nd book!

You find yourself at Grillby's thinking about a certain friend of yours. Of course, by an either amazing or cruel twist of fate, you get stuck having an overnight stay at Sans and Papyrus' house. While you're there, you happen to meet up with that comical friend of yours who thinks it's a good idea to hang out with you. He creates feelings in you that you didn't think was possible. Front cover isn't mine and all Undertale characters belong to Toby Fox as well as the game! It's my idea, though! Wanted my title to be You Are my Sunshine, but it was too close to another Sans x Reader title!

"Because not all family is to share the same skin. . . Literally." ~~~~~~~~~~ The Village wasn't your home any longer. That ended ever since you had fallen down. Now, you were to fend off for both you and your sibling, while hoping for nothing more unfortunate to cross your path. What you didn't expect was that you would end up meeting with the monsters, which were the ones the villagers loathed seeing every moment of their lives. The ones the villagers had warned you so much about were the ones who actually lend out a hand, in more ways than one. That's when you realized your home wasn't on the Village. No. Your home was with them - It was with the monsters. ~~~~~~~~~~ ** Small Note/Before You Go On: This is meant to be a 'x Reader' of sorts, and the events will take place after the ending of the Pacifist route. ** Undertale belongs to its creator Toby Fox. I only took the liberty of putting my thoughts into a fan fiction.
