Lee In Joon is a South Korean singer, dancer, and former member of XING (씽), THE BOSS (대국남아, known as DGNA in South Korea and Daikoku Danji or 大国男児 in Japan), and ASC2NT (어센트). He graduated from Incheon Dongsan High School and later earned a bachelor's degree in Child Counseling and Therapy from Digital Seoul Culture and Arts University.

He made his debut in 2008 when he joined as XING's new vocalist (under the stage name Soul). The group debuted in 2006 but faced constant lineup changes until their eventual disbandment in late 2009.

He re-debuted in March 2010 as THE BOSS's sub-vocalist with their single album, “Admiring Boy.” The group initially promoted in Japan before returning to South Korea in late 2011, following their agency's strategy of prioritizing Japan. Promotions alternated between the two countries until 2012, when Open World Entertainment went bankrupt, leading them to move to Poom Entertainment and later return to XING Entertainment. The group went into an indefinite hiatus in early 2017.

In mid-2023, he reunited with 2 former group mates during the competition "Peak Time", but Park Hyun Chul (known as Karam) faced controversy when old pictures of him smoking, dancing in nightclubs, and celebrating the birthday of a Japanese AV actress were posted online. As a result, the 3 members left the show to avoid further negative attention.

In December 2023, he signed a contract with NewWays Company (뉴웨이즈컴퍼니) and re-debuted in May 2024 as ASC2NT's main vocalist and sub-rapper with their first single album, "Expecting Tomorrow". Unfortunately, he went on hiatus in October of that year due to health issues and never returned to the lineup. The agency announced his departure in July 2025. No further information has been provided regarding his next steps.
