When ruby rose and yang xaio long were young they downloaded an app that allowed them to receive pictures and messages from an anonymous person that looked like a child their age wearing a beowolf costume that actually looked real. Soon they named the person Y/n and believed he was just another kid, though ruby and yang's Mom's, summer rose and tai xaio long weren't really ok with it thinking it was a stalker. But soon everything changed after when they tried to fix the problem. and it could change everything they ever knew.
