Only after many days have passed we will fully know what made Jungkook give up the chance to become the next heartthrob of the world and join the military.
Some Koreans used the example of Elvis Presley to justify BTS' enlistment. Well, that was 60 plus years ago, and after he was released in 1960, he was not in the best of shape and was powerless against the British Invasion.
This year's halftime show would have featured JK if he had not been hoodwinked by RM to join the military asap.
Since Taehyung's future would probably lie in acting, and not singing, it would have been fine for him to show up in the show run by Lee Jieun, an actress (notwithstanding all the harm she had caused to BTS while she was singing), but JK is a different case.
Military changes a man. Whether you like it or not. Someone who was in the military can never really show their 'fresh' face ever again. JK would be quite washed up, fed up person when he is released.
As he becomes more independent, he would realize how Bang and RM had used him, and robbed him the chance to become the greatest soloist to have come forth from Asia.
It would cost him north of $200 million at least.
It seems he was not well advised by those who were close to him, and those who said there would be a career for him after he is released. But there is something called momentum, and by 2025 it will be a different world and JK would be a different person as well.
Some Armies will prefer the more 'serious' side of BTS after they are released, older, wiser but not necessarily more appealing, with the younger fans already having moved on to more recent acts.
That kind of strategy works with Lee Jieun, whose fans are stuck in Korea, but not BTS or JK, whose fans are all around the world and are flexible.
Korean fans are worse than useless. Abandoning them will not cause an act any harm. Let IU, Lim Youngwoong, Akmu and the trottists have them. future acts will learn from BTS' sorry example, but it is doubtful whether they will rise that high to begin with.
