Overview
- Gemstone E&M, which announced the reunion on Monday, Sept. 21, 2026, said all four original members are preparing to resume full-group activities.
- The reunion brings together Lee Hyo-ri, Ock Joo-hyun, Lee Jin and Sung Yu-ri for the first sustained group effort since their 2005 digital single "Forever Fin. K.L."
- The agency says it will plan and manage the comeback in cooperation with the members and their representatives, but it has not yet announced release dates, formats or a schedule.
- Each member has pursued separate careers in music, television, musical theatre and acting since 2005, a factor that shapes logistics and fuels strong fan interest in seeing them work together again.
- Gemstone E&M says it will unveil activities in stages so fans can experience new moments; key things to watch next are formal release plans, performance dates and any tour or broadcast partnerships.
