Hyunsuk

Hyunsuk (현석), born Yoon Hyun-suk (윤현석), is the youngest current member of CIX and one of the artists who kept the group's performances light on their feet even as the lineup tightened. Working under C9 Entertainment, he developed inside a catalog built on sleek hooks, precise choreography, and a slightly darker mood than many of CIX's direct peers. The post-Bae Jin-young era pushed Hyunsuk into an even more visible role as the team moved forward as four. C9's April 2026 statement also makes him the last current member to remain under contract, with his term extending through May 31 while he finishes drama filming, which places him at the very end of CIX's current timeline.
