Recently, Rain shared a photo taken with his fellow celebrity soldiers, including Park Hyo Shin, Kim Ji Hoon, KCM, Epik High’s Mithra Jin, and comedian Lee Jin Ho. The photo was taken on March 21 in Hanoi following the “2012 Korea-Vietnam Friendship Concert,” where Rain and the rest of the group gave a special performance.

The concert was held to celebrate the 20th anniversary of the establishment of diplomatic relations between South Korea and Vietnam. In the photo, Rain is standing in the middle, looking to have slimmed down a bit, with the rest of the soldiers surrounding him.

Rain joined the Korean army last October and has served as a trainee at the bootcamp until recently when he transferred as a PR soldier. On March 26, Rain participated in the “2012 Seoul Peace Music Festival,” returning on stage for the first time since his enlistment.
