A human fell into the Underground, and began befriending every monster they came across, including the skeleton brothers. Their acts of kindness seemed to be genuine, giving the monsters no reason to distrust them... Until the human pulled a one-eighty and killed Sans when everyone least expected it.

This is the story of how Papyrus grieved over his older brother's death, how he discovered the truth about his mysterious sibling... and eventually, how he decides to avenge his sibling's murder.

But in the end he'll forget everything once the timeline resets again, right? That's what he's afraid of. 

(Based on the AU "Disbelief Papyrus," but with an original twist. There are no pairings except for what's canon. This is mainly Papyrus-centric, but it does focus on mystery of Sans during the story.)

My Fault - Underfell Fanfiction (Sequel to Your Fault) by DragonzRawesomE
20 parts Complete Mature
{COMPLETED} It has been just two weeks since the event that changed Papyrus' life forever. Too late, it seems, he realized what he had. And now that it is gone, he has fallen to pieces. How, or if, he will be able to cope, he truly does not know. And as if that wasn't enough, there are countless mysteries in store for this burdened skeleton-- coming from people he thought he could trust, and in places he thought that he knew. Will Papyrus ever be able to solve the mystery behind this devastating chain of events? Or will he, too, fall prey to the ever-expanding void that is engulfing the souls of himself and everyone around him? PLEASE NOTE: This book is the second in its series. It contains major spoilers to the first book, as well as this book may not make much sense without having read it first. So, if you want to keep the excitement of the first book without any major spoilers, I HIGHLY suggest going and reading that first. It is titled Your Fault.
