2011–2015: M&D, military enlistment and coming back to work

Heechul carried out his mandatory military service from September 1, 2011, to August 30, 2013. He served as a public service worker for 23 months after undergoing four weeks of basic training at the Nonsan military camp in South Chungcheong Province. At the time of his enlistment, he was a host in the variety show Secret, as well as one of the hosts of the talk show Radio Star. His role in Radio Star was taken over by bandmate Kyuhyun. Shortly after he had enlisted, Kim Jang-hoon released the song "Breakups Are So Like Me", which is a duet with Heechul. During live performances of the song on Music Bank and Show! Music Core, his part was performed by bandmates Yesung, Eunhyuk and Shindong. He was selected to be an internet broadcast radio DJ in January 2012 on Space for a Rest-Visible Radio. The program was aired through Seongdong District's homepage, as that's where Heechul was serving his two-year mandatory military service. He hosted from January 20 to May 18, 2012, and from January 14 to July 26, 2013.
