Why Seongmin matters
Seongmin has already survived one debut, a stage-name era, a group rebrand, a departure, and another survival show. Calling him “the visual” and leaving it there would be lazy.
Before ONE PACT
He first debuted in TOO in 2020 under the stage name Jerome after placing eighth on World Klass. TOO later became TO1. Seongmin left the group in 2022, returned to his birth name, and competed on Boys Planet, finishing thirty-fifth. By the time ONE PACT debuted, he was not a blank trainee waiting to be told where to stand. He had already learned what happens when a group’s name, direction, and lineup can change around you.
What Seongmin does inside the group
Seongmin gives ONE PACT a lighter vocal color and an expressive face that the camera finds quickly. His performance value is often in the reaction beat between major moves: the glance, the delayed smile, the shift from elegant to slightly dangerous. He also has a third-degree black belt in taekwondo, speaks Japanese, and is known for photography and girl-group dance covers. Those details explain why his movement can look neat without feeling stiff.

Seongmin does not currently have a separately verified official solo-video catalog. ONE PACT releases remain attached to the ONE PACT group profile so group totals are not duplicated as individual activity.
