Want to talk about falling into the wrong place at the wrong time? Y/N definitely scored big time on that one. One moment she's falling, the next she finds herself trapped underground with a monster that wiped out his own kind. He's a cold-blooded killer that never shows any emotion. Though, as time passes, she finds out that Sans isn't as heartless as he plays himself to be. Hello! Writer~San here! Cover art and Undertale AU/Characters aren't mine, but the story definitely is. I hope you enjoy it!!!!

No lemons, just fluff, the book is now officially completed! I will not be taking ANY MORE REQUESTS! Thank you! Hope you like them!

It's only been a few years since monsters have been released from their underground prison. In some towns, monsters are welcomed with open arms. Others? Not so much. Y/N is a 22 year old girl that lives a pretty simple life. Sleep, eat, work, relax at her daily cafe, go home, sleep. Then the routine starts again. However, her routine is thrown off when she keeps running into a skeleton, supposedly named Sans. She would like to get to know him more herself, but there's one problem.. He doesn't talk. Of course, Undertale belongs to Toby Fox, not me lol

It's been over a year since the Underground opened up and the monsters living under the earth swarmed to the surface in their thousands. The human and monster governments are taking their sweet time coming to any kind of agreement regarding monster rights and citizenship, but for the most part, in the less politically-active parts of the nation, life continues as it always has. In your sleepy little town, there are bills to be paid, tables to be waited, and few to no adventures to be found. So when two skeleton monsters move into the empty house near the café where you work, you welcome the changes they bring with them. You knew if you let them into your life they'd make interesting friends. What you didn't expect was that getting to know these remarkable strangers would be like coming home.

Your life is mediocre, not horrible, but not great either. You yearn for love, but can't seem to find anyone. You own a blue/black heart necklace, not knowing it ties you to someone else... This is my first x-reader story, hope you enjoy!
