You climbed the famous Mt. Ebott to prove to a group of your friends that humans don't disappear when they go up the mountain. While walking around the peak, you trip over a root in the ground and fall forward, expecting to hit the ground. Instead, you were met with open air. As you fell down the large hole, you let out a shrill scream before hitting the ground and blacking out. When you wake up, you find yourself in the Underground where monsters had been banished to by the humans. You meet several monsters down in the Underground, some becoming friends and some becoming enemies. One particular monster though, has been making your heart flutter and your tongue get tied. Sans the skeleton. A new threat appears when a human that had been thought to be dead comes back and threatens you and the entire Underground. Will you be able to stop them or will you be used as a puppet and watch your friends die? Maybe the only thing that can defeat LOVE is love... Author's Note: this was my very first story so sorry if there's bad grammar or confusing scenes, enjoy my awful writing! ((COVER ART IS NOT MINE))

This is the second story to "Unexpected Love" so if you haven't read the first book you should probably read that first so you aren't confused. But anyways, enjoy! You wake up on the cold floor in the old lab that Alphys had found. You felt strange and the only life form that you could find in the Underground was Chara, who had somehow gotten out of your consciousness and now looked like a normal human. You find out that six months had passed and a child named Frisk had freed everyone and the barrier was broken. Now, with Chara somehow befriended, you leave the Underground in search for your monster friends. And most importantly... Sans. Author's Note: enjoy my awful writing! ((COVER ART IS NOT MINE))

You never really understood why the humans never accepted the monsters. All you knew were 2 rules. One, kill any monster you see on the surface. And two, don't enter the underground. Although a so-called "barrier" was down, and monsters were free to walk the surface, nobody wants them up here. You had witnessed countless monsters turn to a pile of dust in front of your eyes. They always fought with such... determination though. And rumor had it, that another war was soon going to break out. You couldn't help your curiosity though, were all monsters truly as bad as you had been taught? And so, one day, you decided to go down to the underground.

(Undertale!Sans x Reader) You've just had the worst week of your life. To make it worse, you've somehow managed to wind up within the code of the video game you once played called "Undertale". You don't know how, you don't know why, but you're in the The Underground, regardless. How will you get back to the real world? What will your challenges with Toriel, Frisk, Papyrus, Undyne, Alphys, Mettaton and Asgore be like, but most importantly... What will The Judge think of your sins, once he finds out who the real culprit of his brother's death was over and over? Will you be best friends. . . or mortal enemies? UPDATES ARE ON MY TUMBLR, @reptilerach, BEFORE WATTPAD!! Go follow that and check other Undertale-related content I post on that blog!! Thanks for reading, and enjoy! *Undertale DOES NOT belong to me, nor do the charaters in this story!! They all belong to Toby Fox. **The concept and plot of the story are my own ideas, but again- the characters and settings are not.
