He is not allowed to have private meetings while outside his Seoul base for official duties such as recording and performing. The ministry says a brief lockup in a military jail cannot be ruled out as a penalty. Kim's agency admits that the two have dated for a month. Rain's agency neither denies nor confirms it. Rain joined the military in October 2011 and is scheduled to be discharged in July.
