Seunghun has announced that he will step away from his career as a singer after CIX brought its team activities to a close. The announcement followed C9 Entertainment’s late-April notice that the group’s operation would stop as members’ exclusive contracts expire, placing Seunghun’s decision within a wider CIX disbandment and contract-ending timeline.1
The move marks a major turn for the vocalist, who addressed fans through a handwritten SNS letter posted on April 29, 2026. In that message, Seunghun said he planned to set aside the title of singer for the time being and live “as one person” outside the stage, while thanking fans and fellow members for the years he spent as CIX’s Seunghun.12
Seunghun Retirement Declaration Follows CIX Activity Halt

C9 Entertainment informed fans through the official fan cafe that CIX would end group activities after roughly seven years since debuting on July 21, 2019. The agency said all parties had reached the view that, under the current circumstances, stopping the team’s operation was unavoidable.13
Korea JoongAng Daily also reported the agency’s position in English, stating that CIX would end group activities and that all four remaining members would leave C9 Entertainment as their contracts reach their respective end dates.4 The company’s notice did not describe the change as a temporary pause with a confirmed return schedule; the available reports frame it as the close of the group’s team activities.
Seunghun’s own statement added a personal finality to the group news. Sports Seoul reported that he wrote that, because he had been singing and dancing since elementary school, starting a new life felt frightening, but that he would try to live diligently.2 In another line from the letter, he thanked the fandom FIX, saying he had been “a very happy CIX Seunghun” because of them.2
Edaily reported that Seunghun also credited fans for shaping the person he had become, writing that his present self was “made by fans.”5 The wording underscored that his message was not only a response to contract news, but also a farewell note to the identity he held as a performing artist.
Contract and Member Timeline
The contract schedule now defines the remaining practical steps for CIX members. BX and Seunghun’s exclusive contracts ended on April 30, 2026, one day after the agency’s notice and Seunghun’s handwritten letter.16 Yonghee is scheduled to enter active-duty Army service on May 11, 2026, while Hyunsuk is set to receive agency support connected to drama filming before his contract ends on May 31, 2026.16
| Item | Confirmed detail |
|---|---|
| Group status | CIX has ended team activities after C9 Entertainment announced the stop through the official fan cafe.6 |
| Debut reference | Reports cite CIX’s debut date as July 21, 2019.3 |
| BX contract | BX’s exclusive contract ended on April 30, 2026.1 |
| Seunghun contract | Seunghun’s exclusive contract ended on April 30, 2026.1 |
| Yonghee schedule | Yonghee is scheduled to begin active-duty Army service on May 11, 2026.6 |
| Hyunsuk schedule | Hyunsuk’s contract is scheduled to end on May 31, 2026, after drama-related support.6 |
The table shows that the end of CIX’s activities is not limited to one member’s statement. The group’s operational halt, two completed contract expirations, one upcoming enlistment, and one remaining contract date together form the immediate post-CIX timeline.
What Seunghun Said About Life After the Stage
Seunghun’s retirement declaration centered on leaving the stage rather than announcing a new entertainment project. Sports Donga reported his handwritten message as saying that he would “set down the name of singer for a while” and try to begin a new life as an individual outside the stage.1
The phrase “for a while” leaves the wording cautious, but the reports consistently describe the message as a retirement announcement from the singer or the entertainment field. Sports Seoul framed it as Seunghun expressing his intention to retire from singing after CIX concluded its group activities.2 Edaily similarly reported that he had declared retirement from the entertainment industry alongside the end of CIX team activities.5
Available reports do not provide a new agency, solo schedule, acting plan, or public activity calendar for Seunghun after the contract end. The confirmed information is narrower: he thanked fans and members, reflected on his long period of singing and dancing, acknowledged fear about beginning again, and said he would work hard in the next stage of life.2

For fans following the broader CIX disbandment news, Seunghun’s letter is the most personal piece of the announcement cycle. C9 Entertainment confirmed the structural end of team activities and contract departures, while Seunghun gave his own account of leaving the title of singer behind. With BX and Seunghun’s contracts already ended as of April 30, Yonghee’s enlistment set for May 11, and Hyunsuk’s contract end scheduled for May 31, CIX’s post-group timeline is now defined by individual departures rather than new team activity.
