Yewang

Yewang (예왕), born Seo Ye-wang (서예왕), is the main vocalist inside EPEX, the C9 Entertainment group that has treated its discography like one long youth document instead of a stack of disconnected comeback slogans. He debuted with the team on June 8, 2021, and his role has stayed clear throughout that run: he is one of the voices that gives EPEX its lift when the production turns tense, bright, or emotionally direct.

That matters because the group has spent the past few years pushing a connected arc from the early BIPOLAR releases into the larger Youth cycle. Yewang is part of the reason those records land with more than concept polish. His tone gives the hooks shape, and his placement in the arrangements helps EPEX move between urgency and release without losing melodic control.

On HITKULTR, Yewang reads less like a generic profile-page member and more like a functional center of EPEX's vocal line. From Youth Chapter 1 : YOUTH DAYS and Youth Chapter 2 : YOUTH DEFICIENCY to Youth Chapter 3 : ROMANTIC YOUTH and the 2026 project Youth : Epilogue, he has stayed visible in the group's most narratively coherent period.
