    (Y/n) had a wonderful life. She always had the nicest clothes in school and she loved her family. Her mother and father loved her dearly, and so did her older brother. One day they went on a family camping trip atop Mt. Ebott. They were having a great time, until they were attacked by a bear. (Y/n) and the rest of her family fled, all in different directions. As (Y/n) was running, she tripped over a vine, and into the underground. Everything was going terrible for her, as she found it wasn't as kind as her parents had told her they were. Until she met Sans. ____ Sans, on the other hand hated his life. The only 'new clothes' he got was a new collar, and the only family he had seemed to hate him. His brother was cruel and brash, acting as if he gave no fucks about Sans nor his feelings. The only trips he ever went on, was everyone tripping him. He was often an easy target for bullying. Mostly just light teasing, and every so often physical bullying. Papyrus never knew. Sans never told him, since he figured Papyrus didn't care since sometimes, he was the one bullying him. But everything changed for him the day the human fell down. He found his savior that day.

    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 wanted to help but it was too late... So, you left. Tears filled your eyes as you thought of the one person that needed you the most... They were gone and it's your fault. You ran and ran trying to escape reality. You thought if you could run far enough or fast enough that you wouldn't have just lost everything that made you want to live and exist... but you did. [CoverArt: By Me <3] [I own none of the artwork within the chapters.] [Spin off of the game Undertale brought to you all awesome people who love Undertale by Toby Foxx]
