The eldest brother Jin, who drew attention for his first enlistment in the group BTS, is enlisting as a frontline unit. On the 13th, on the fan community Weverse, Jin answered a fan's question, "Is your brother's birthday next month, are you excited?" Considering that Jin's birthday is on December 4, it is observed that he received an enlistment notice to enlist at the Frontline Recruit Training Center, not the Nonsan Training Center, during December of the year. Regarding this, the agency Big Hit Music did not disclose the specific enlistment date or location. Jin announced his plan to enlist after his solo concert in Busan last month, and after returning to Korea after performing the single "The Astronaut" with the band Coldplay in Buenos Aires, Argentina, he filed a request to cancel his enlistment.
