WARNING: there are some of my OCs in the story, one of them is jingix, he's a villain, and well, he's made of hate,LOVE, fear and determination and he wants to end the world, he's a replacement for bete noir from glitchtale, but because i don't own glitchtale that is from camilla cuevas from youtube, i'll use my own character, he looks like a mini devil- you know what, imma put a pic of him when the time comes.
Y/N was the eldest of the royal family. Her life was great. She was turning 16, the age where she'll be able to help her parents with royal duties, and get more privileges, when her younger sister, Frisk, goes missing. Y/N's life falls apart, while her mother heartbroken, and her father started to ignore her. Not having a great life, she decides to run away, learning about the hard life of being a citizen. Having to live on the complete opposite side with poverty, she learns she has to hide, and everyone isn't what they seem. Not even her.
