On March 25, Block B member/actor P.O. updated his Instagram, revealing that some of his close staff members had thrown him a congratulatory party for his upcoming enlistment in the marine corps. 

The SNS photos showed P.O. posing in front of a sign which read, "Congratulations on your enlistment! Let's meet again when you're a more mature person after completing your service in good health! Signed, all of your loving staff." 

P.O. also held up a cake signed by his staff members, with the printed text, "Soldier Pyo Ji Hoon. Get your head on straight! It's your first time enlisting, isn't it?"

It seems that P.O's dramatic reaction made the staff members laugh, as they eagerly closed in for a photo or video of the sad-funny(?) moment. 

Meanwhile, P.O. is expected to begin his service in the marine corps on March 28.
