Though Se7en told fans that he would be enlisting this month, he kept the date a secret until his recent fan meeting.

It's now been revealed that Se7en will leave for the Uijeongbu 306 Reserve Battalion on March 19th to officially start his post as an active-duty soldier.

During Se7en's 'talk concert', which marked his 10th anniversary since debut, he announced, "Today's the 9th. There are 10 days left. I'm enlisting on March 19th. I really wanted to tell you, but I saved it for the concert. I received so much love the past 10 years, and I had a great time. I'm always thankful."

The singer also answered questions about his promotions, commenting, "My heart tells me to continue [after I'm discharged from the army]... However, �I think it'd be wrong to promote under the name 'Se7en' when I'm 50 years old," causing laughter.
