Roshi posts backstage photo ahead of 'Don't Be' performance on Simply K-Pop

Roshi (강주희, 27) posted a photo on June 28 from backstage—profile against a blackout curtain—before performing Don't Be on Simply K-Pop.

The single marks her first release under EGO Group and her first official track where she handled both writing and composing. Don't Be pairs rhythmic guitar with pop-rock elements, capturing that particular feeling of quietly falling apart inside a relationship while keeping up appearances.

This is just the opening. Three more singles arrive before everything gets bundled into an EP called FLAT. The project frames itself as a series about stepping away from other people's standards and finding your own pace. (Four singles into an EP gives each track breathing room before the full picture lands.)

Roshi debuted November 9, 2017 under Dorothy Company, founded by Shin Seung-hun. She stayed with the label exactly eight years—through November 9, 2025. On that anniversary, she announced on her fan cafe that the official fandom name would shift to the English spelling "Blueming." The fan cafe hit 3,000 members in March 2019, crossed 4,000 by June that year, and had grown to around 6,600 by late 2022 and mid-2023.
