A Violent Atmosphere (AU Sans' & Papyrus' X Reader)

So, here you were. Standing in front of your old home you stayed in. Your mother had a child at a young age and she knew she couldn't take care of a child. So she left you at her mother's until she had her life sorted. That happened when you were 12. When you had gotten into a few 'Fandoms' of some anime and some games. Your favourite game was really fun, but now, you could barely remember much of it. All you knew was that you LOVED the music in it!
Now growing up with your mom, you barely had time to yourself, what with helping around the house all the time, apart from when you went to sleep. When you had hit 16, she got back into her old habits but wouldn't let you go to your grandmothers. It was only when you turned 19 that she turned her life around. Got a good house, well paying job, nice car and heck- she even got a boyfriend.
Even with her trying her best to make you happy, you preferred chatting with your grandmother than your own mom. Of course, that was to be expected. She taught you everything you knew, how to cook, clean, sew and even some self defense. But your grandpa helped with the heavier side. Like... Weapons.
Your grandma died recently and left the house to you. Much to your moms slight annoyance. Your grandpa was away with work all the time and just stayed at hotels all around the world. So you moved in.
Already the first night, and you've already caused trouble for others. But they grow to enjoy your presence!
Oh, and you find out your grandpa... Doesn't do normal work?
And your grandma... Wasn't human?

Well, find out all this and MORE on Y/N's adventure!
