Jin of BTS is making a big move after the success of his song "The Astronaut" and the band's recent Billboard record.

It was revealed on Friday, per AllKpop, that the K-pop idol had applied to the Military Manpower Administration (MMA) to withdraw his appeal to postpone his military conscription.

His enlistment was delayed until the end of the year, on December 31.

This comes after his management company, Big Hit Music, confirmed in October that all seven members of the world's most successful K-pop boy band are preparing to serve in the military.

Jin, born Kim Seok-jin, is BTS's eldest member, and his conscription was postponed until the end of the year due to a revision to the Military Service Act in 2020.

His decision followed a heated discussion over whether BTS should be granted exemptions in honor of their contributions to boosting South Korea's image. As is well known, all non-disabled men in the country are obligated to serve in the military for around two years.

Why Did Jin Delay His Initial Enlistment Plans?

Jin discussed the delay of his imminent enlistment in a WeVerse live broadcast on October 28, as well as his new solo single, which was released on the same day.

A few days after returning from Argentina, where he performed with Coldplay, the 29-year-old said that he would be drafting documentation for his forthcoming military enrollment.

With several changes before that announcement, Jin explained, as translated by Soompi, "I originally planned to enlist in June but to be courteous to fans, and I waited until our October performance [in Busan]. I didn't want a tearful performance so my [enlistment] announcement was delayed."
