He made his debut in January 2017 as TOP SECRET's main vocalist with their first mini album, "Time's Up". The group changed their name the following year to TST but faced controversy with Kyeong Ha's legal charges later that same year. They were never able to gain a steady fanbase and presumably disbanded due to inactivity in early 2020.
In April 2023, he signed with Nature Space (네이처스페이스) and re-debuted as a soloist with the EP album "Restart", and in July, he joined XEED as the new maknae with their second mini album, "Blue". The group debuted in December 2022, but the company decided to add him to bring more balance to the lineup.
In March 2024, the agency unexpectedly announced the group's disbandment, which happened the following month.
He is now an independent artist.
