    On a dark, windy and rainy night in a bad part of Chicago, a skeleton named G, walked home from work. He doesn't normally walk home, preferring his motercycle, or even his teleportation powers. But something made him walk this night. Fate. G finds himself saving a young girl from a horrific death, and then taking her home to keep her alive. What he didn't expect, was for the girl, much older than first appeared, to flip his whole world upside down. A curse, layed on his SOUL many years ago, may have the second chance of being broken, but DEATH has other plans. To make matters worse, the girl has a deadly disease, with little hope of survival. Can G save the girl who he has sworn to protect and take care of? And in turn, can the girl break his curse, and let him finally live the life he was ment to? 《GasterSansXOC》 (Frequent updates, and this promises to be a very long book)

    (Cover Art is not mine.) You don't remember who you are, or who you used to be. You've woken up in an abandoned costume shop with amnesia, after the second human and monster war. The monsters were victorious this time, and practically all that's left of humanity is trapped in the Underground. You find a journal explaining how to survive trying to live among monsters, and you become aware that you are one of the less than ten humans still on the surface. Deciding to live among the monsters instead of risk it in hiding, you enter a monster-filled city, and meet a certain skeleton. Undertale: ©2015 Toby Fox. All Rights Reserved.

    You worked for the newspaper, doing a simple editing job and a few other things here and there. Ever since monsters came out of the ground, though, rent has sky-rocketed for you. You thought you could deal with it, but after a few months you need a roomie to help with the rent. Which, fortunately, you got one! But, unfortunately, you're too awkward to fucking deal, man. And this skeleton just laughs at you for it. -this fic has lots of cussing in it, and is a slowburn!- -if you have any suggestions of drabbles i should write for the story, comment!- all gaster!sans fics are way too serious to my liking on here, so I made more of a slice of life/comedy fanfic! hopefully this will go well HOOWEE Cover art by junkpilestuff on tumblr!!
