Hyunsuk

Hyunsuk (현석), born Yoon Hyun-suk, is the youngest member of CIX and one of the artists who helped keep the group's clean, performance-first identity intact from debut through its most recent four-member chapter. He debuted under C9 Entertainment in July 2019, arriving with the bright tone, sharp movement, and easy onstage fluidity that gave CIX a lighter contrast inside a darker concept lane.

That role became more visible after Bae Jin-young left the group in 2024. CIX's 2025 EP THUNDER FEVER and its connected world tour pushed Hyunsuk further into the center of the lineup, not as a sudden replacement figure, but as part of the balance that carried the team into a leaner era. His public profile widened again in 2026 when C9 said his contract would run through May 31 so he could finish drama filming while the other current members closed their label chapter earlier.

That timing leaves Hyunsuk at a real hinge point. He already has the catalog history of a 2019 debut act, but the next phase of his career will depend on how he converts CIX experience into a broader idol-actor profile. For now, he remains one of the clearest entry points into CIX's later-era story.
