UX1 is a South Korean boy group formed by former and current U-KISS members Hoon, Kevin, and Kiseop. The group officially announced its formation on November 1, 2025, by launching official social media accounts and unveiling a team logo and introductory video. In their announcement, the members greeted fans, stating, “We’re meeting you again under our new team name, UX1. Please look forward to us.”
UX1’s first official activities will take place in Japan, beginning with the concert series “First Winter Story”, scheduled for December 20–21, 2025, at Dream Square in Osaka, followed by shows on December 24–25, 2025, at TIAT Sky Hall in Tokyo. Further details about the performances are available through FC LIVE’s official social media channels.
The three members were originally part of U-KISS, a group that debuted in 2008 with six members: Alexander, Soohyun, Kibum, Eli, Kevin, and Dongho. Over time, the group underwent several lineup changes, with Hoon and AJ joining in 2011 and multiple members later departing. While U-KISS remains active as a five-member group consisting of Soohyun, Hoon, Kiseop, Alexander, and Eli, UX1 represents a separate project bringing together Hoon, Kiseop, and former U-KISS member Kevin for new activities under a fresh name.
I absolutely adore Kevin and I love U-Kiss so win!!
