The only way to the top in this world, this world born of war, born of death, the only way of ascension? ...is to become someone you don't want to be. And so I've got to break a promise. Because I've got a job to do. And there's no-one who's going to keep me from it. ~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~ How can something so enticing have such awful side affects? All the itching and the scratching from withdrawl keeps me out of check, I am fixated on all of the things that we were together, but those are fragments that are better off lost forever.

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!!

[Y/N] lived with her adoptive mother Toriel for a while. How long is that? About three years. Throughout the time, the monsters in the Ruins know her as if they were her siblings. Flowey became way nicer each day around her, losing his soulless behavior. He cares about her so much he promise to protect her. All was well... Until she sneaked out of the Ruins. Going from Grillby's to the Librar(b)y, she went around having fun. Laws did apply, 16 being the age to leave past curfew, 18 being the age to finally date, and 21 to legally marry. One day, I slipped from my own mouth of the presence of a Princess... And Asgore ordered the Royal Guard to break the door to the Ruins... (Cover art made by Zayn-Inverse on DeviantArt)

When we got hit by a truck-- A small one--my mother wrapped her arms around me, keeping me safe. And the next day, it's when it started. My father started abusing me, giving me cuts and bruises. I always wore long sleeves then, too. I cut my arms, and it doesn't hurt. Not even one bit. My cuts aren't as bad as my life. One day, when I was out of hope, I ran away. 'Yup. I ran away. I didn't care anymore. I just wanted to have a new life. I lived in the alleys two days, and I still kept cutting my arms. But in the alley, was someone, a demon if you will. He grabbed me and tried to do it. But when my hopes fully drained, someone saved me. And I never knew this person would change my life. [Note: Slow updates.]
