Yoonhak (Formerly Spica Yoonhak) (윤학)

The structured facts provided describe Yoonhak (윤학), born Jung Yoon Hak on December 2, 1984, a Korean artist currently active as a member of PLAYBACK7, previously associated with Spica. However, the narrative material supplied — the editorial bio and recent coverage — concerns Jung Yong-hwa of CNBLUE, an entirely different artist. That content cannot be attributed to Yoonhak, and no further verified detail about his solo work, discography, or career milestones is present in the provided material.

On the facts that can be confirmed: Yoonhak is a Korean artist, standing 180 cm, who performed previously under the name Spica Yoonhak and is currently a member of the group PLAYBACK7. Beyond those data points, the available material does not support additional claims about his music, chart history, or career trajectory.

A fuller profile will be published as verified material becomes available.
