Okay so we all know that in South Korea every male between the ages of 20-35 have to enlist in the military for 2 years.
The way that the government does this is that once you are of enlistment age you have to report to the government and from that day on the can just randomly contact you telling you that in (for example) two months you'll begin your training.
And up until last year agencies were able to postpone their idols enrollment dates to better fit their schedules, but since there was a huge thing about all the corruption on Korea that has now been stopped and the government is now in control of ALL South Korean mens enrollment dates.
And we all know that it's bound to happen... That BTS are going to have to enlist at some point or another...
Now ALL of BTS are of enrollment age! Which means that they could literally be called at ANY time!!
These are the dates that some ARMYs suspect that they are going to be enrolled:
Now these could be off by a year or two since we don't actually know when the government is going to call them BUT STILL!!THAT MEANS THAT JIN IS LEAVING IN TWO YEARS!! T_T
The only thing that could possibly prevent them from going is the war ending between North and South Korea, which has been going on for more than 60 years, and thankfully that is in the talks so there is a possibility of that happening before 2020!!
Also when BTS enlist I'm pretty sure that there isn't going to be NO BTS music for 8 years, they'll probably release solo albums or just have comebacks with less members (like Super Junior and BIGBANG for instance)
This is from all of the information that I have gathered so I'm sorry if I had missed somethings , also I am not Korean so sorry if I had explained some things incorrectly^_^
I need a hug and someone cry with T_T
