Intro. You and Jungkook used to be highschool sweethearts during the time you two used to be school mates at School of Performing Arts Seoul (SOPA) on 2013. By that time he was still a trainee for BTS and he was about to debut alongside RM,Jin,Suga, J-hope, Taehyung and Jimin but the Big Hit Entertainment were strict with some rules for them since they're about to debut. These rules included dating, school related things and personal matters, diet, schedule and hard work. With that, Jungkook decided to break up with you. Not because he doesn't love you anymore but because he needed to in order for him to debut and follow his dreams. He didn't told you the reason for the breakup but you just let him go because you think he just doesn't love you anymore. Now it's 2019 and BTS became one of the fast rising Kpop boy group due to their hardwork,looks,talents,stage presence, humor and attitude while you dropped out of college to start doing art commissions and singer and composer on YouTube.
