Jungkook has a twin, and it's a sister. One day Jungkook falls ill and tells his twin sister to fill in his spot in BTS. She cuts her hair, and steps out as Jungkook in the world of kpop.

*Jungkook doesn't  have a twin sister, fyi. This is just fanfic. And no, I don't have anything against Jungkook for making him ill, just the way my mind thinks, mkay? Otherwise, hope you enjoy!*
