'The Astronaut' singer entered the boot camp at Yeoncheon, a town near the tense border with North Korea, for five weeks of basic military training with other new conscript soldiers. The oldest BTS member accompanied the others as he enlisted in mandatory service.

For the unversed, every new military recruit must have his hair cut short before undergoing a five-week basic training programme at the start of their service. South Korea requires all able-bodied men in the country to serve at least 18 months in the armed forces.
