(EDIT: STORY IS BEING REWRITTEN! PLEASE CONSIDER REREADING THE REWRITTEN CHAPTERS [chpts. 1-31] ON MY PG!) You are a young teenager girl. You have a happy normal life........kinda. You're best friends with the angel of monsters, Frisk. One day you follow her and sans to strange place on accident.You see lots of hers and hims. But one in particular caught your eye. BTW THIS IS A FUCKING SLOW BURN SO STOP WHINING! (Edit: I made this back when I didn't know what I was doing. So lots of the story is very confusing. I will be rewriting this through the summer. I'm sorry)

☆This will be a Nightmare x Reader story☆ ◇ Slow updates 😁 ◇ Trigger warning: -Cussing -Violence -Blood -Death -Abuse -Bullying If you are not comfortable with these, then I suggest you don't read this book. ♧Y/N is not the most popular soul in town, she's bullied relentlessly by fellow classmates, abusive parents and never felt like she belonged so...What happens when a certain group of bad skeletons take an interested in Y/N's soul? ... Especially their leader ♧ ☆I do not own any of these characters besides Shizu as she is my own version of a *****. (SPOILERS BE BLOCKED) ☆Also, this is my own version of Nightmare. He will not be like the Nightmare in Underverse and underverse will not have happened. I'll explain Cross backstory later but other than that, I just felt the need to clarify after I've just caught myself up with underverse. ☆Toby Fox has full rights to Undertale, I am not claiming this as fully my own idea. ☆All these pictures are not my own work unless I say so. ☆I'm still new to writing so if you do not like my content, please don't leave hate. ☆Edits will be made during the process of writing the rest of the chapters and most likely after it is finished. ☆You are free to leave suggestions, I'm alright with constructive criticism just don't be mean about it. And if you have suggestions for the story itself, I'll take it into consideration but don't expect me to use it, I will give credit to the ones who made the suggestions I liked and used. ☆I'm writing for my own enjoyment, so don't expect me to be dedicated to writing this story. Plus I keep getting new inspirations for other stories, so I might write them for a bit as well. ♤Thank you, I hope you enjoy the story♤ 🏅#1 in #Tobyfox

"How can Cupid... how could you be so cruel?" I curse lowly. Who could have imagined something like this happening to me? It had been so long since everything happened, but somehow the pain in my heart never left. The memories starts to flashback into my mind as I start to process what is happening in front of me, and why my past heartbreaks are all gathered at the same place. Nightmare, my childhood friend and first love. My first ever heartbreak. I tend to find him in everyone I have loved. He was cold and unpredictable but he was also warm and considerate at times... He was complicated but I loved all of him. Error, the one I chased over and one I was not willing to give up. He stood up from the rest and gave color to my world. All my poems were dedicated to him and him alone. Dust, possibly my other half. He felt like my soulmate. Everything about him made me feel like we were meant for each other. We shared the same interests about everything but I was wrong about one thing. We didn't share the same feelings. His heart belonged to my best friend. Killer, a flirty guy who people often rumored as the playboy. Most girls had fallen in love with his charm and personality. I was one of those unfortunate ones who fell right into his trap. But I... I saw something in him that other people couldn't see; there was something beneath those sweet grins. Horror. My comfort. My home. The one who filled the gap. The one who I think of every little nice thing. I love him so much to the point where I feel like the pain that would come with it would be worse than death. It had to be avoided. Cross. I was always drawn into him. He was my best-est friend. The one who I can count on everytime. The shoulder I can lean to when needed. The one who made me feel like I am the best thing that ever happened in his life. He was perfect while I am just... me. So why did I have to see them again? Why now? Love is not something I want to go through again... never again. <\3

You were a problem in the multiverse, and he had been given the duty of watching over you in the same apartment you lived in. Their only intention with you was to learn more about what you were and your use and then discard you, just like any other job. That was all there was to it, and nothing else could be done. Shit. He wasn't supposed to get attached to you like this. But now that he was, you weren't going anywhere.

Based off of Beauty and the Beast. You are living a quiet life when you are forced to flee into a forest to escape a forced marriage. While running, you stumble across a certain someone's castle... Howdy, my darlings! This is Editor Valery. This book was originally written on Quotev. It'd be appreciated if you checked out this book there too! There is a sequel. It'll take me a while to put it on here, so feel free to read the sequel on Quotev whenever. This book was first started in 2019, so the Author Notes from my sister will be old. She doesn't want to change anything, so I'll be the one moving everything here! The Editor Notes will change a bit cause I don't like my notes anymore- Anyway, enough of that. This is a Fem Reader story, so enjoy that. You're all beautiful and amazing and I love you all! Enjoy the book! Mwah!
