Baekseung

Baekseung (백승), born Kim Hyun-woo, is part of the core performance and rap line that gives EPEX its edge. Since debuting under C9 Entertainment in June 2021, he has been one of the members carrying the group's youth-series identity across an unusually structured release run that favors continuity over one-cycle noise.

That continuity matters. EPEX spent 2024 and 2025 building a long-form chapter through Youth Chapter 1 : YOUTH DAYS, Youth Chapter 2 : YOUTH DEFICIENCY, and Youth Chapter 3 : ROMANTIC YOUTH. Baekseung stayed central to that arc as the group tightened its storytelling, sharpened its live chemistry, and entered a more emotionally direct phase. The 2026 mini album SoHwa (韶華) : Epilogue closes that sequence and gives his page a cleaner current anchor than a generic member bio ever could.

Baekseung's appeal is not about volume for volume's sake. He works inside EPEX as a stabilizer, someone whose rap positioning and stage discipline help the group keep shape while its concept evolves. For readers arriving through the Youth era, he is one of the members who best represents what EPEX has been trying to build.
