Profile
SEONGMIN (Oh Seong-min) is a vocalist and visual member of ONE PACT. Before the group’s formation, he debuted with TO1 as Jerome and later appeared on Boys Planet. His earlier group work brings experience with different performance and recording styles to ONE PACT.
ONE PACT’s member-produced releases offer him space to develop a more individual vocal colour. He was one of the five members featured on the solo-track project ONE PACK and selected Signal, a reflective song accompanied by an official special video, in July 2025.
His ongoing group work includes the SANE promotions, the TUNED IN single and the international OUTSHINE concerts in 2026. In interviews, SEONGMIN has discussed the importance of good teamwork and a desire to explore different styles without losing the identity of the group.
