CORTIS will officially begin their music show activities with the title track "REDRED" from their second mini-album. Composed of Martin, James, Juhun, Sunghyun, and Geonho, CORTIS will premiere their new song stage on the 23rd on Mnet's "M Countdown."

"REDRED" is a song that combines an addictive beat, intense melody, solid vocal skills, and memorable choreography. The members participated not only in the music but also in the choreography and video production, showcasing their capabilities as a "young creator crew." They took part in creating a performance that intuitively expresses the lyrics and message, earning credits as co-choreographers. The moves of shaking both hands near the ears during the "that's red-red" and "fluttering ears fluttering ears" sections or crossing both arms to form an X have already attracted attention.

The conceptual performance film released on the HYBE LABELS YouTube channel on the 22nd recorded 1 million views within a day, thanks to its unique cut editing and choreography. On the same day, the "REDRED" video released on Mnet Digital Studio M2's official YouTube channel "STUDIO CHOOM" caught eyes with the members' vivid expressions, synchronized group dance, and vintage outfits that reinterpret early 2000s street fashion.

Starting with "M Countdown" on the 23rd, CORTIS will continue their comeback momentum by appearing consecutively on various music shows such as KBS2's "Music Bank" on the 24th, MBC's "Show! Music Core" on the 25th, and SBS's "Inkigayo ON THE GO" on the 26th. The second mini-album "GREENGREEN" will be officially released on May 4th, and on the same day at 8 PM, they will hold the "GREENGREEN Release Party" at S-Factory in Seoul to meet their fans.
