Chp1: WE JUST WITNESSED A MURDER

Self inset brrr. Undertale aus and omg Upside Down exists in the future, but with less missing cases and disappearances. I'm very sad and lonely + got better at writing.

I don't think anyone will see this but do credit me or send it to me if drawn! (: [fanart is cool]
Also no scheldule on this book, it's updated when it's updated
I do not own Undertale or anything in this book, only the self insert plus a couple of friends, and the Au isn't the 'og Undertale' :)
