CIX member Seunghun has announced his retirement from the entertainment industry, closing his activities as a singer after the end of CIX’s team promotions was confirmed. The Seunghun retirement announcement followed C9 Entertainment’s notice that CIX would stop group activities as members’ exclusive contracts reached their end dates.1
Seunghun posted a long message on social media on April 29, 2026, saying he would step away from the title of singer and begin a new life outside the stage. The announcement came during the same week that C9 Entertainment confirmed the conclusion of CIX’s team activities through an official fan cafe notice.2
Seunghun Retirement Confirmed After CIX Activity Closure

Seunghun’s message centered on his decision to leave the entertainment industry rather than continue under a new agency or solo track. In the post, he said he would “set down the name of singer for a while,” a line reported from his official social media statement.1 He also expressed gratitude to fans, saying, “Thanks to you, I was a very happy CIX Seunghun.”1
The decision was reported one day after C9 Entertainment’s April 29 announcement on CIX’s future. The agency stated that CIX would stop team activities, with Sports Chosun quoting the company’s position that “CIX will stop team activities.”3 The company’s notice placed the decision in the context of contract expirations and future plans for the remaining members.
CIX, which debuted in July 2019, had already gone through a lineup change before the latest announcement. Bae Jin-young left the group in 2024, after which CIX continued as a four-member act.4 Seunghun was known as CIX’s main vocalist and had also participated in B.D.U, the project group formed through Mnet’s ‘Build Up’.5
Member Contract And Schedule Timeline
The end of CIX’s activities is tied to several member-specific dates. BX and Seunghun’s exclusive contracts with C9 Entertainment ended on April 30, 2026. Yonghee is scheduled to begin active-duty military service in the Army on May 11, 2026, while Hyunsuk is set to leave the company after receiving support for his ongoing drama filming schedule, with his contract ending on May 31, 2026.6
| Member / Item | Confirmed Status | Date |
|---|---|---|
| CIX team activities | Agency announced conclusion of group activities | April 29, 2026 |
| BX | Exclusive contract with C9 Entertainment ended | April 30, 2026 |
| Seunghun | Exclusive contract ended; announced retirement from entertainment | April 30, 2026 |
| Yonghee | Contract to end with active-duty Army enlistment | May 11, 2026 |
| Hyunsuk | Contract to end after support for drama filming | May 31, 2026 |
The timeline shows that Seunghun’s departure from the industry is part of a broader transition for the group, but his decision is distinct from the other members’ next steps. The available reports confirm contract expirations, military enlistment for Yonghee, and continued drama-related support for Hyunsuk before his departure from C9 Entertainment. They do not state new agencies or future entertainment plans for Seunghun.
What The Announcement Means For CIX
C9 Entertainment’s notice marked the end of CIX as an active team after nearly seven years from debut. Reports described the agency and members as having discussed the issue for several months before agreeing that continued team operation was no longer unavoidable under the circumstances.3
For fans and industry observers, the announcement combines two related developments: CIX’s group activities are ending, and Seunghun is retiring from entertainment. The first is an agency-level decision concerning the team’s operations and contracts. The second is Seunghun’s own public statement about stepping away from singer activities and beginning life outside the stage.
The reports do not provide further detail on Seunghun’s post-entertainment plans. They also do not describe a final group release, concert, or separate farewell schedule linked to the group activity closure. Based on the available source material, the confirmed facts are limited to the agency notice, member contract dates, Yonghee’s enlistment schedule, Hyunsuk’s drama-related support period, and Seunghun’s retirement message.

Seunghun’s retirement closes his run as CIX’s vocalist at the same time the group’s official activities come to an end. With BX and Seunghun’s contracts already concluded on April 30, 2026, and Yonghee and Hyunsuk’s departures scheduled for May, CIX’s final transition is now defined by confirmed contract dates rather than an announced comeback or farewell event.
