Lee Jun-young to Begin Mandatory Military Service: What Fans Should Know
South Korean actor and former U-KISS member Lee Jun-young, known professionally as Jun, will enlist in the military on July 21, 2026, to fulfill his mandatory service requirements. As a citizen of South Korea, Lee is required to complete his service before turning 30, a standard legal obligation for all able-bodied men in the country.
Why Lee Jun-young Is Enlisting Now

South Korean law requires all men between the ages of 18 and 30 to serve in the armed forces for a period typically ranging from 18 to 21 months. According to the Military Manpower Administration (MMA), these duties are a civic requirement intended to maintain national defense readiness. While the specific branch or role—whether as an active-duty soldier or a social service agent—remains unconfirmed, the enlistment marks a temporary pause in Lee’s active entertainment career.
Career Background and Transition to Acting
Lee Jun-young first entered the public eye in 2014 when he debuted as a member of the K-pop boy group U-KISS. While he remains associated with the group, he transitioned his professional focus toward acting around 2020. His filmography has grown significantly since that shift, featuring roles in high-profile projects such as the thriller series Weak Hero Class 1 (2022) and the Netflix film Love and Leashes (2022).
His career trajectory mirrors a common path for many K-pop idols who move into television and film, often leveraging their established fanbases to secure leading roles in K-dramas. His recent work continues to solidify his reputation as a versatile performer capable of handling both dramatic and comedic roles.
What to Expect During His Service
During his time away, Lee’s fans—often referred to as “KISSme” from his U-KISS days—will see a hiatus in his new project releases. It is common for high-profile actors to complete their military service during the prime of their careers to ensure they can work uninterrupted afterward.
* Service Duration: Typically 18 months for Army enlistees.
* Public Status: Lee is expected to maintain a private life during his training and service period, as is standard for enlistees.
* Future Returns: Most actors return to the industry within two years, often timing their “comeback” project to coincide with their discharge date.
