Intro. Jungkook is your brother who has to leave you for a business trip. That's why he asked his best friend Taehyung to take care of you for the few days he's gone. Taehyung is five years older than you and is 23 years old and you just turned 18 and you're upset about this and say you don't need a babysitter.
