CORTIS are set to return with a more intense sound, confirming "REDRED" as their upcoming title track.

The group surprised fans on March 30 by unveiling a teaser image for "REDRED" through their official SNS channels. The track will serve as the title song of their second mini album GREENGREEN, scheduled for release in May.

GREENGREEN reflects the group's current identity and direction. The album is described as a collection of what CORTIS truly pursue—eliminating elements they reject while highlighting their present artistic vision, shaped by all five members' tastes.

Ahead of the full album, "REDRED" will be pre-released on April 20 at 6 PM (KST), alongside its music video and performance film. The group will also begin music show promotions with the track.

This marks CORTIS's first comeback approximately eight months after debut. Anticipation is rising, with GREENGREEN surpassing 565,000 pre-saves on Spotify as of March 31.

Despite being rookies, CORTIS are also set to take the global stage. They will perform at Lollapalooza Chicago this August as the only K-pop boy group in the lineup.
