It's been a few years since Y/N started her family. Without Honey, she made due with what she had; that being the cafe, her brother-in-law Blue, and her two twin sons. Of course she missed Papyrus. There was no doubt about that. Though, she had to learn to accept his passing. Her sons did not... One of her sons soon makes a secret deal, causing the whole world to reset back in time. The family of three wakes up in the underground. Two family members are now in dire need of medicine. They resolve to find help, get medicine, and find a way out. That is, until a familiar face steps back into their life. AAAAA- HI! It's Oreo aka Writer~San! This is a SEQUEL to one of my books! SECOND! If you haven't checked the first (New Purpose), THEN yoU nEeD to STaRt thErE! XD Also, Undertale and its characters don't belong to me, and is rightfully owned by Toby Fox. All Underswap characters rightfully belong to their owner as well. The writing in this book, though, is completely mine! Please enjoy (owo)~🖤

Toriel has noticed something about Sans. Every few weeks he comes home rather late, and sneaks something into his room. As it turns out, it's a bottle of pills. Thinking he was becoming addicted, she threw the medicine out. Wrong move. (Inspired by The Owl House, cover is my art)

(UnderTale belongs to the amazing Toby Fox, not me! This one shot is based off the Book of Atlantic, from the Black Butler series, specifically the part where Elisabeth is strong and awesome. And this is brotherly love, not fontcest. The cover is my own art.) After going to the surface, the monsters are met by a zombie apocalypse. The gang finds them surrounded by a horde of zombies, all weak and beaten to their last bars of HP, none of them finding enough strength to face the zombies who seek their SOULS. And the first person the zombies close in on is Sans.

PLEASE READ BEFORE GETTING INTO THE STORY: In a story of Undertale where Monsters are bound to the laws of having a Soul Mate, (Y/n) doesn't understand her own role in this world of deceit and cruelty... not until she meets a certain skeleton. While she is best friends with Frisk, the two trust each other at all times. Although... how far can (Y/n) run from her past? Especially when both her and Frisk are primary targets to it... --- Okay, so an important note. This story will have shorter chapters. Probably around 1500+ words each. Whenever I am unable to preform a larger update for my other story, I will instead do this one. Anyway, I hope that you guys enjoy! Sans will also have a possessive nature in this, fair warning. Also, this is rated mature. So keep that in mind while reading. Also, as all of my stories have gone on thus far... the image DOES belong to me, please do not steal it/ use it without permission! And here are your important key words while reading the story! (Y/n): Your name (E/c): Eye color (H/l): Hair Length (H/c): Hair color (S/c): Skin color (F/c): Favorite color

Y/N's best friend Blueberry (also known as Underswap Sans) invited them to move into the shared/connected apartment next door. They could hang out all the time! It's an awesome opportunity and the chances of it happening again are slim. Being closer to friends means a lot, especially in this tough life on the surface. Blue has introduced Y/N to other Sanses before, and they've never had any issues with them. Even so, what happens when they find out that Blueberry now has a very creepy one as a roommate? His cracked-open skull and unclear motives for being here are a major concern. Still, it's not as freaky as the stranger's ghostly appearances and obnoxious actions. Blue says "he's just misunderstood." Should Y/N follow their conscience, warn Blue and run? Or listen to Blueberry's optimistic advice, and befriend their new neighbor? Hello! owo ... Undertale aus and art presented in this book are not mine. However, the story is 100% my work! I hope you enjoy it!
