On January 17, 2AM member Jinwoon's label Mystic Entertainment told news outlets, "Jinwoon has applied for acceptance to the army's music corps, and if he is accepted, he will enlist this coming March. The decisions have yet to be posted, so we are currently waiting for the results." 

Jinwoon's fellow 2AM member Jo Kwon is currently serving as a member of the army's music corps. Jinwoon will also be the final member of 2AM to carry out his mandatory military service. 

Best of luck to Jinwoon!
