안녕 안녕 말하지 마 (Jeon Jungkook x Reader) {Completed}

You're Rap Monster's little sister by two years. You're 18 and your brother asks you to help out in one of their videos since the actress quit. You immediately said yes, since you never see your brother. You get there and the rest of BTS welcomes you. What happens when the innocent maknae, Jungkook, catches your eye?
