Lee Chang Sun, known professionally as Lee Joon, is a South Korean singer, dancer, actor, model, DJ and former member of MBLAQ (엠블랙). He graduated from Seoul Arts High School and later obtained a bachelor's degree in Information and Communication Studies from Kyunghee Cyber University and a master's degree in Content Management from Soongsil University. He made his debut as an actor in 2008 with a role in the MBC sitcom "Here He Comes" (그 분이 오신다) and was set on becoming an actor but kept failing every audition. He then met singer Rain, who convinced him to join his agency and a new group he was forming. He made his debut as a singer in October 2009 as the group's leader, main dancer and lead vocalist with their first single album, "Just BLAQ". They were managed by J. Tune Camp (제이튠캠프) and were heavily promoted by both the agency and by Rain, who often included them as performers during his concerts and fan meetings, so they enjoyed some success. In early 2010, he revealed that he was diagnosed with bipolar disorder and that he also suffered from severe insomnia. He decided to leave the group in December 2014 to focus on his acting career. He enlisted for his mandatory military service on October 24, 2017, and was discharged on December 19, 2019. He is represented by Prain TPC (프레인TPC).
