According to reports on October 26, industry insiders shared, "JIN will apply (the cancellation of postponement) as soon as he returns from Argentina, and will soon start arranging related matters including his activities."
JIN is scheduled to make a special guest appearance on English band Coldplay's 'MUSIC of the SPHERES' world tour concert in Argentina on October 28 (local time), and perform his solo song 'The Astronaut' for the first time.

The agency also shared that other members of BTS will also serve their mandatory military duty one by one; according to their individual plans.

Since JIN has decided to withdraw the postponement, he is expected to enlist in the military within this year―immediately after he receives an enlistment notice from the Military Manpower Administration.
