Chapter 1: McCormick is a Mistake

Y/N has been living in South Park for quite some time and has never really gave any attention to the parka wearing boy, until the day he shows up at her door with a request.
That is when Y/N might have made the biggest mistake of her life, or is it truely a mistake?
