ATBO member Jeong Seunghwan has officially begun his mandatory military service, marking a temporary pause in his music career as he fulfills one of South Korea’s most significant national duties.
On October 20, 2025, his agency, IST Entertainment, confirmed that the singer enlisted earlier that day at the Nonsan Army Training Center, a well-known facility where countless K-pop idols and actors have started their military journeys.
The announcement came as a surprise to many fans since neither the agency nor Jeong Seunghwan had shared any prior notice about his enlistment.
However, as explained by IST Entertainment, this decision was made in accordance with Seunghwan’s personal wish to enlist quietly and without public attention.
Agency’s Official Statement: Respecting His Wishes for a Quiet Enlistment
IST Entertainment began their statement by extending gratitude to fans who have consistently supported both ATBO and Jeong Seunghwan.

They expressed optimism about his return, saying he will come back as a more mature and improved version of himself after completing his military service.
