Stiles is possessed by the Nogitsune. It’s been weeks since it started, but so far it was usually just bad dreams, or Stiles not being able to read. Now it’s gotten worse, he can’t tell the difference between dreams and reality. And sometimes, Y/n can’t tell if it’s Stiles or not. Y/n and Stiles has been best friends since forever and recently they’ve grown even closer, not exactly together but not exactly friends either. But Stiles obviously had a crush on Lydia since forever too. Y/n was about to confess their feelings, but when Stiles got possessed, they figured it’s for the best to wait. They’re in Stiles’ room now, just talking, and Y/n is more and more suspicious and paranoid, not knowing if it’s really Stiles or Void Stiles.
