Sept. 20 (UPI) -- South Korean singer Lee Chan-hyuk quietly joined the Korean marines this week.
Lee's agency, YG Entertainment, said the K-pop star entered boot camp Monday in Pohang, South Korea. He will complete six weeks of basic training before he is assigned to a unit.
"We gave him a quiet send-off, in accordance with his wishes," the agency said.
Lee's sister, Lee Su-hyun, performs with him as Akdong Musician. The Korea Times reported Lee's parents, a few close friends and YG Entertainment staff saw the singer off at the training center.
Many K-pop stars postpone their military service until their late 20s or 30s. Lee explained he enlisted now to train with others his age and "to build diverse experiences and improve [his] musical skills."
Akdong Musician last released its second studio album, Winter, in January. The record peaked at No. 7 on the Billboard World Music chart, and includes the singles "Last Goodbye" and "Reality."
