Before debuting, he spent some time as a trainee at OUI Entertainment and was set to debut as part of the agency's group (temporarily named OUI BOYZ) in early 2017. The group even released the pre-debut single "Hug Me", but afterwards, their debut date kept being postponed, and all members decided to leave the company without debuting.
He switched agencies and made his debut in February 2020 as DKB's main vocalist, acrobatic and producer with their first mini-album, "Youth".
In October 2023, he was caught by police while drunk driving and his license was revoked. A week later, the group's agency, Brave Entertainment (브레이브 엔터테인먼트), announced his departure from the group.
Due to this incident, he appears to be out of the entertainment industry.
