I'd kill for you Jeff The Killer X Reader Chapter 1

Warning: Language

I go with my best friend and the two guys she took with us, into the woods
"Hey don't touch me" I said
I walked away wishing something I never should have wished
Murders have been committed yesterday last night
Maybe.....maybe I should be careful what I wish for next time

Finding a note saying.....I'd kill for you
Who is this person? Why did they leave me a note?
