*This book will take place during the comic by deadpool4ever at Tumblr.* I would suggest the dub by two all nighters on YouTube. :3 I'll put it up there. You are papyrus' teacher at the snowdin school in the underground. and yes you are a human. but why would they keep you alive if you are human. the thing was, you didn't have a soul. but you did have a brain. a very good one in fact. you were caring for all your students. enough to become a certain little skeleton's favorite teacher. and Enough to bond with him so much that you get to meet his dad. W.D Gaster.

OLD AND BADLY WRITTEN THE REWRITE IS POSTED ALREADY DISCLAIMER: The god figure created in this fanfic is purely fictional. He is purposefully made to be prideful and cruel and is not supposed to represent any god. I am religious myself and I did not intend to attack anyones believes with this book. An angel. Sign of hope for humans, yet a nightmare for monsters. Powerful, skilled and...beautiful. But what happens when one rebels against the cruelty towards monsters? What happens when she's banished to the underground, only with wings as a painful reminder of who she once was. What if she's found by the Royal Scientist? What if the nightmare every monster is scared about, is just as broken as they are? And what if she'd find something she would never imagine she'd find in the underground...love? *Cover edited by me. The pictures used in the story belong to their original creators. If any of them aren't okay with them being used, I'll take them down* Started: 21.12.2018 Ended: 22.08.2021 09.03.2019-Number 1 in gaster! 07.02.2020- Number 7 in undertale! 25.02.2020- Number 4 in undertale! 15.04.2020- Number 1 in undertale! 11.10.2020- Number 1 in papyrus! 03.06.2021- Number 80 in fanfiction!

You were in your element when you stood on a stage. You could confidently sing the melody, serenely take the harmony, basking in the attention and relishing in the feel of your heels hitting the stage and the strain of your vocal cords. You'd been singing for fours years, but the best career decision you'd made was joining up with Mettaton for several duets. You often performed with the monster, and he'd become your best friend, but despite his constant pestering you had yet to meet the rest of his friends. *Authors Note* I originally started this story in 2016, but never finished. I've recently regained my writing mojo, and decided to rewrite, edit and finish Can You Hear Me?.
