Y/N is a young adult who attends college regularly as they should. They live in a low class overpriced apartment due to the lack of funds to buy a dorm. Their life is boring and they're tired of it until one day disaster strikes their Universe, and is kidnapped by the attackers as a 'pet' But to one of them they are much more... A very heartfelt story with a slightly unstable storyline. I love you guys, and I'm so excited to share one of my over imaginative stories of fantasy and what I call 'ROMANCE'. Thanks a million. Alright, alright, maybe smut if I get enough views and votes, please read/comment. Drop a vote if you will? Maybe follow this new author? Cover art by me. (Small edit: yeah so the first like 80 or so chapters are a bit more wonky than the rest... I have to go in and correct all the pronouns and typos so this book isn't completely finished... still enjoy tho)

(Y/N) has always had a problem with sleepwalking and night terrors, ever since age 10. As she grew, her night terrors became less frequent - but her sleepwalking became more dangerous. She would wake up several blocks from her house, or sitting in her parent's car, and all efforts to stop the dangerous habit were pointless - she could undo locks, move seamlessly through her home and even hold simple conversations as if she were awake. It was almost as if something was drawing her away from home. One mid-winter morning, a blizzard kicked in, and (Y/N)'s boss insisted that she stay home. She took this as an opportunity to get a short nap in, only to wake up in the deep, snowy forest of Mt.Ebbot, miles from home. With the world spinning around her, she makes her way into a cave to get shelter from the storm, unknowingly bringing herself to the mouth of the Underground. Inspired by the lovely CrusnikRoxas's story, 'Cadaverous', and music by Jack Conte, particularly 'Eat'. Content warning for explicit gore, (self) cannibalism, self harm and sexual content. Cover is temporary. Reader is not Frisk, Chara or Aliza. Can also be found on my AO3, HeyitsSmile.

𝘍𝘳𝘦𝘴𝘩 𝘚𝘢𝘯𝘴 𝘹 𝘙𝘦𝘢𝘥𝘦𝘳 | 𝘙𝘰𝘰𝘮𝘮𝘢𝘵𝘦𝘴 𝘈𝘜 You were expecting a quiet college roommate. Maybe a little awkward, maybe a little messy. You were not expecting Fresh. He's loud. He's neon. He wears Heelys in the cafeteria. And now? He's crashing into your life-literally-and moving into your two-bedroom apartment. You and Fresh couldn't be more different-he's all chaotic energy and bright colors, while you just want to pass your classes and keep your sanity. But between late-night takeout, emotional baggage unpacked at 2AM, and one too many accidental heart-to-hearts, something starts shifting. This was supposed to be a normal semester. So why does your heart start racing every time those stupid wheels squeak down the hall?

"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

I have always been unlucky with love huh... I'm the 'Unrequited Love Repeater' that's right. It's almost like Cupid himself hates my entire existence. I met them again. My failed romance stories. The people who made me learn from my mistake. The people who taught me how to love myself. The people who broke my heart and mend it back. The people who made my smile brighter. The people who made my heart warm. The people who took pages from my book. Pages of happiness, sadness, anger, and well... past memories. Nightmare, my childhood friend whom I had always admired when I was young. He loves me but it was the type of love I didn't yearn for. Killer, the playboy who made me laugh the hardest. I wanted him in my arms but he wanted to be in her arms. Dust, my bestfriend who I resonate with a lot. Same music taste. Same vibes. Different feelings. He fell in love with my bestfriend. Error, my 'rival' at academics. I did everything I could to acquire his love. I guess you already know who lost between us. Horror, my guardian angel. Not literally. Comfort. He gave me comfort. He made me feel special but at that time I was already too tired to even try. Cross, my online bestfriend. My feelings on him are uncertain. I don't think I'm ready to address that yet. But after all these years, I still love them. Someday I will be brave enough to mutter the words "I still love you". ___________________ ↷I have the rewritten one published!

"the healer likes t' sleep. like, a lot." Axe looks at the sole female AND human member of Nightmare's subordinates. She was only ever awake for about 8-10 hours a day, rarely ever 12, it was both fascinating and irritating at the same time. He was damn sure humans would be awake for more hours than that, he even asked Murder at the time if it was normal. Said skeleton didn't give a single care though, his words: "who cares, makes her more tolerable. 'sides she gets her job done." The cracked skeleton just couldn't shake off the feeling that there was more to it than meets the EYE. ━━━PHOTO CREDITS: Whale鯨豚 [@Whale5511] on X! ━━━MOST NOTABLE RANKING: #1 in sansxreader, horrortale, something new and badsanses on 23/12/2025 #1 in undertale on 25/12/2025 #3 in bittersweet on 24/12/2025 #5 in reader on 24/12/2025 #19 in sans on 23/12/2025 ━━━━━━━━━━━━━━━━━━ DATES PUBLISHED: 001 ━━ July 29th of '25 002 ━━ July 30th of '25 003 ━━ August 1 of '25 004 ━━ August 3 of '25 005 ━━ August 6 of '25 006 ━━ August 8 of '25 007 ━━ November 8 of '25 008 ━━ December 22 of '25 009 ━━ December 23 of '25
