The penalty is the lightest a South Korean soldier can face. Paparazzi photos recently showed Rain with actress Kim Tae-hee when he wasn’t allowed to have private meetings while outside his base for official duties such as recording and performing.

Rain is fulfilling his two-year mandatory military service as an “entertainment soldier.” His meetings with Kim raised suspicions that the military was coddling popular entertainers with special favors because they help enhance its image. Officials deny it.

Rain has starred in the Hollywood films “Speed Racer” and “Ninja Assassin.” Time magazine named him one of the world’s 100 most influential people in 2011.
