    You had a happy family and never got a big problem, just that you never believed into you. Your parents tried everything to help you but in vain. One day, you decided to stop bothering them. You went to the darkest place of the forest and end your life. At least, that was what you wished. ( I'll skip the moment in the Ruins, so you'll fall into the snowy forest.) (Btw, I do not own the AU or the characters that are present in Undertale/Underfell) Edit-Some elements of this story might be trigfering and since I litterally have bo idea of how younger thought this was okay, we'll just say that the reader has Stockholm syndrome.

    Once, there was a battle between two races. Humans and Monsters. The Humans thought Monsters were Vicious, Threatening and Merciless. Though the Monsters thought the same way. The Humans always treated the Monsters as if they were beneath them. So the monsters stood up to them. Eventually, The humans became tired of the monsters fighting back. That was when the war started. Both sides fought Viciously. In the end... The Humans won. Casting a Magic Barrier, they sealed them Underground, In the mountian of Mount. Ebbot... never to be seen again. Though, that was a very long time ago. Now to be considered a myth. A fairytale to frighten kids into not wandering into the forest or near the mountian... Correct? A young woman, about the age of 17, has been orphaned since she was young. Now abused by her Caretakers in her Foster home. With no will to live... She grows curious about the legends and rumors. About the Children "Dissapearing" and going "Missing", near the mountian. She sneeks from her "home", finding a large, Never ending Abyss. Falling down, hoping to end her life... Only to be given another chance at it. So here goes the start of Y/N's new life, free of the abuse and depression of her past home. ... ... ... Or so she thought...

    hey guys I thought it might be a good Idea to write this story but what's it is about is that a girl named seacresea is well abused and bullied because everyone well thinks she is a nerd and well they think her singing isnt really that good so she doesn't sing out loud to others and well she just locks her self out and lies to people that care about her but I should write the story now alrighty.

    UNDERTALE?? IN MY 2020?? -Gender neutral so it's for everyone!- -Underfell- -most art comes from deactivated artists so I will try and credit as accurately as possible!! Many years have passed since monsters were banished underground for bringing upon a war against the humans, once they were lost to their own rage, Mount Ebott turned into a tall tale. A story about the mountain being cursed and having hidden ways of trapping people underground. They say if monsters did exist, they had no mercy in their souls. That humans were the 'good guys'. A human that fell into their world, found the tales were true about monsters existing but hopes they couldn't be as ruthless as they have been told. They wanted to believe that even these so called horrible monsters can be good if they just tried.

    You were being abused. You couldn't take it anymore. But you also couldn't leave your kitten, Millie. So you gently put her in your backpack and got going. Your father wasn't looking. He was drunk, anyways. He probably didn't even notice the window in your room being opened. You made sure to lock your door before you left, then you decided to go for it. Millie was being quiet. She most likely understood what was happening. You were running away.
