Jungkook was your best friend since high school, always quiet and nerdy, with round glasses falling down the bridge of his nose and hoodie too big for his body. It was the same thing after you both went to college, but when he decided to do an exchange program for six months and go completely IA, claiming he needed that time for himself, you didn't expect him to be back as a complete different person. The shy nerdy now had a sleeve tattoo, piercings on his ears and face, and even rode a bike.
