Before debuting, he spent time as a trainee at IST Entertainment (IST엔터테인먼트). He first appeared on TV as a contestant in the survival show "The Origin - A, B Or What?", where he was eliminated in the 5th episode. After the show, he joined Fantagio as a trainee, and he was set up to debut as part of their new group (later named LUN8), but was not selected for the final lineup.

He decided to leave the agency and returned to IST, this time becoming part of the official lineup of the agency's new group. In January 2026, they released the OST “One Last Chance” for the drama "No Tail To Tell" as their first pre-debut single. He made his debut in March of that year as part of TUNEXX with their first mini-album, "Set By Us Only".
