This is my own au. It contains a oc (He appears pretty quickly). And my first story. Info about the au/backstory: Chara(16) and Frisk(16) were twins. Chara was jealous of Frisk. Their parents loved Frisk, but hated Chara. So did Frisk. One day their parents got in a accident and died. Frisk was heartbroken and blamed her sister for it. So one day Frisk took Chara up Mount. Ebbot.... Edit from 15 Jul 2019: I warn you, this is confusing and kinda cringe worthy. I'll try to make it better in later chapters.
