Arguably the most fearful words for any male idol group fans: military enlistment. It seems like the inevitable moment isn't too far for VIPs, as media outlets have begun reporting on Big Bang's mandatory service requirements.
By end of this year or the beginning of 2017, T.O.P needs to enlist in the military, as he can no longer delay his mandatory service. In order to prevent Big Bang's hiatus being prolonged, the other 4 members, who also have to enlist sooner or later, are planning to serve in the military around the same period.
While the other 4 members have the option to delay their enlistment a little further, the members evidently believe that enlisting together at once is the best option. It's terrifying to imagine a couple of years without Big Bang, but it seems like they are trying their best for V.I.Ps.
