Seungjun

Seungjun (승준), formerly known to many fans as J-Us, sits in the performance spine of ONF. K&I Entertainment's current member page uses Seungjun as the official name, making the shift part of the group's broader reset story instead of a side note disconnected from the music.

That makes Seungjun relevant beyond choreography talk. The first ONF release under K&I Entertainment has to prove that a management change can sharpen identity instead of flattening it, and the member-facing continuity around artists like Hyojin, Wyatt, and Seungjun is central to that case. The group's current chapter is already being watched closely in HITKULTR's ONF:MY SELF report.

ONF has never worked like a plug-and-play idol brand. It depends on members who can carry concept, performance, and tone together. Seungjun remains part of that engine.
