He made his debut in November 2020 as BAE173's main vocalist with their first mini-album, "Intersection: Spark". However, as the group has not been able to promote as much, PocketDol Studio (포켓돌스튜디오) allows him to participate in survival shows.
In January 2024, the agency decided to make him part of the co-ed group A SIX. They released the digital single, "Love is All Lies". They have not released any new material since then.
In June 2025, the agency decided to launch a new project group combining some members of BAE173 and FANTASY BOYS. He re-debuted as part of DOUBLE 0NE with their first mini-album, "Xpert".
His contract with PocketDol Studio expired on June 30, 2026, concluding his activities with BAE173.
