    frisk the human was walking through the judgement hall and was greeted by sans who let her pass knowing that she didn't kill anyone especially his brother but sans felt something off like something's out of place so he decided to follow frisk. he saw frisk walking to the throne room and talked with asgore she then went to the barrier where sans watched their battle. sans saw frisk's soul shatter in a million peices but one big peice of the shattered soul vanished. his eye sockets widened because he knew frisk couldn't reset when her soul was missing a piece especially a big one but the problem was even bigger than that when he discovered that the other au's frisk is missing as well. (so this is called an introduction right?...........then hello I guess. I'm the author of this trashy story if you hate it then don't read it cause this is my first book so read if you dare anyway I hope you enjoy the story.)

    A skeleton and a human, could never happen. It's like saying a world of black and white can be a world of color. Well it can..because love makes it. And if everyone can have live why can't it be between a human and a monster.

    "Now for poor little Frisk." He began to say. He better not make something up just to keep her here. I swear, this girl was to much of a goodie-goodie to have done anything too bad. "Mental asylum for three years." What?....... t-this can't be right. I looked at Frisk and she turned her head to face me. "I'm sorry" she said in a whisper. What was she sorry about? What did she even do to get in there? It seemed like Asriel read my mind because he responded with "Charged for voices in her head, split personalities, and even murder in past timelines."

    The monster realm was much different than the human one, with that separation it was hard to get along and soon a war started, families died, monsters and humans. It wasn't a good time for anyone, children and teens left to fend for themselves while the world wrecked havoc. After years of this chaos it seemed to ease, only for Monsters to hit twice as hard, now enslaving any human they could find as pay back. They took everything from you, well everything that you had worked for that is. It's been about 11 years since the accident happened I was 19 years old currently so that happened when I was 9 I've been alone for 11 years. Taking care of myself and I got pretty good at it to. I hated the monsters, despised them for what they did, but now as I'm alone running away from one, fear was the only emotion flowing through my body. What happens when you get caught by that monster?
