On December 11, all seven BTS members reunited to send off RM and V at the Nonsan Army Recruit Training Center in Chungcheongnam-do. According to reports, a total of 6 vehicles entered the training center, with all BTS members coordinating their schedules to gather on this day.

After RM and V entered their training centers, photos of the group reunion were quickly shared on various online communities, including Weverse.

On Weverse, Jin left a comment on one of the photos uploaded by fans and shared a hilarious story.

He wrote, "I'll share an after story. 

Jin: Hey Hope, the new trainees are talking to me like this. Is this proper?

J-Hope: Hyung-nim, I'll work on disciplining them.

Jin: Hyung-nim? Is there a 'hyung' in the military? Is it right for you to talk (to a superior) like that?

J-Hope: I apologize.

End of story."

Jin, the first member of BTS to enlist in the military last December, has taken on the role of an assistant instructor at the New Recruit Training Center in Yeoncheon-gun, Gyeonggi Province. This center is part of the 5th Infantry Division of the Republic of Korea (ROK) Army. In his role, Jin is responsible for training new recruits at this division, showcasing his adaptability and leadership.

Amidst his duties, Jin found a light-hearted moment to joke with his fellow BTS members, who are now beginning their military service as his juniors. Adding a humorous twist to the military hierarchy, Jin, who holds the rank of sergeant, playfully interacted with J-hope, a corporal, thus joking about the usage of "hyung-nim." This friendly banter highlights the strong bond among the BTS members, even as they navigate their military commitments.

Netizens love Jin's short anecdote about his encounter with the other BTS members who are now newly enlisting in the military.

Netizens commented, "The trainees: RM, V and drill sergeant: Kim Seok Jin," "They're so cute," "Jin always makes the mood," "I love how Kim Seok Jin uses his vacation day to go see his members and not on his birthday," "I love how Jin is the same hilarious Jin we know," "We laugh thanks to Jin," "I wish 2025 comes quickly so they can all gather and share some military stories," and "This is so adorable."
