(Y/n) finds herself in a bit of pickle when Ink Sans explains to her about the condition of the Sanses of the multiverse. No matter what, she is determined to help Ink Sans and Error Sans to find a solution, and protect the others from the hacker. Although, it turns out to be a bit more difficult than she thinks. The multiverse Sanses had been turned to kids, and together, they are impossible to tame. How will the trio manage the kids? Will Ink and Error ever tell her their feelings? How will Core Frisk react? How will turn everything back to normal? How will they fight Nightmare Sans? Will they win? Or will the multiverse be forever consumed with despair and misery? Let's follow (y/n) on her journey and see what happens next. I do not own the multiverse or any of its characters, I don't own you either. I do not own Undertale. I only own the added characters like Hacker and P.

This book is long and needs a lot of work, so I don't think that I will continue to write in here, especially since I've left the undertale fandom now.

Warning! There is a chance that there will be spoilers for the pacifist run of undertale. I recommend finishing that before reading this. There won't be any spoilers for the no mercy run, so don't worry about that! Also, don't worry about anything NSFW/lemon if that's not what you're into-there won't be any of that here. You're a human that's fallen down into the underground. You've decided that you'll stay instead of going home after fighting Asgore and sparing him. Now, you had made some great friendships while in the underground-but one of those friends in particular was one you'd like to be a little more than friends with... Aaaa an X reader fic! I haven't done one of these before, but I hope you still like it!

~Okay, so I'm putting this story under construction because I wrote this in the seventh grade and I know I can do better. I plan to rewrite every chapter before moving on. Don't worry, I have a plot and conclusion ready to be written, but I know that my story could be much better. Don't expect another update for a long time. In the meantime, check out my bookmarks if you're interested in more Undertale content not by me but way better! THIS STORY IS NOT ABANDONED, JUST UNDER CONSTRUCTION. I love you guys~ <3 ~~~~ "Stupid abominations like you don't deserve to be alive!" He picked her up by her fragile and stick-thin neck. What had she done to deserve this? She dangled six feet off the ground, at his eye level. "You are not worth existence. Go and die in some abandoned alleyway. The only thing you're good for," He spat before flinging her out the open window. No larger than the size of a tennis ball, she fell and fell. The wind rushed past her, flipping her ears against her head like whips. Why'd he have to live on the top floor? Even if she wanted to use her wings, they were too broken, too weak to be of any use. Might as well accept her fate now. Her dull, cracked scales stinging from exposure to the harsh summer sun. The tail she called her own flapped uselessly in the air. If she survived this fall, what would become of her? Sure, bittys were popular amongst both humans and monsters, but she wasn't like every other bitty. Other bittys were cute. Other bittys had many of the same kind. Little Bros, Baby Blues, they had more than one. She couldn't be more alone. She couldn't be less cute. Of all the bittys, who would want one so broken? Who would put up with an abomination like her? What was a single, broken, lonely, dragon bitty to do?
