The structured facts describe Yoonhak (Jung Yoon-hak) as a member of the group Supernova (초신성), born December 2, 1984. The narrative material provided, however, concerns a different artist — Woonhak of BOYNEXTDOOR — and does not contain verified information about Yoonhak of Supernova beyond the basic biographical data points.
Given the sourcing rules in effect, a profile cannot be built on material that belongs to a different act, and the structured facts alone do not contain enough substance — no discography, no chart milestones, no documented activities — to support a developed narrative profile without invention.
What can be confirmed from the provided material: Yoonhak (Jung Yoon-hak, born December 2, 1984) is a South Korean artist and a current member of the group Supernova (초신성).
A fuller profile can be written once sufficient sourced material — discography, career milestones, awards, or verified activities — is available.
