YooOne (유원)

As the leader and main vocal of Off The Cuff, YooOne — the stage name of Kim Jeong-hyun — built his public identity around the group before pursuing a path outside of it. Beyond that framing, the available material does not support additional sections on discography, achievements, or solo activities without risk of invention.

If K-Pop!t holds editorial copy specific to YooOne's solo work, Off The Cuff's releases, or verified career milestones, supplying that material would allow for a fuller, properly sourced profile. As it stands, expanding further would mean padding a thin record with unfalsifiable filler — which this outlet's house style does not permit.
