Prime Minister Han Seong-sook referenced lyrics from rookie K-pop group CORTIS on June 8 while preparing for her confirmation hearing. She took office on July 1 under the Lee Jae Myung administration.
Han quoted the line "I'll spare no effort in boldly crossing barriers as traffic lights change and times change" from the song "REDRED." She later said her younger sibling, a fan of the group that debuted in 2025, introduced her to the music.
The reference highlights CORTIS' appeal beyond typical teenage listeners. Data from Melon on June 22 showed listeners in their 40s accounting for the largest share of streams for "REDRED," with ages 40 to 60 making up 43 percent.
Group member Seonghyeon noted surprise at older fans during busking events. The five members average 18 years old. Songs like "REDRED" and "FaSHioN" use playful retro sounds and everyday Korean expressions instead of typical K-pop production styles.
