The group CORTIS expressed their gratitude to fans after achieving their first music show win with their new song "REDRED."

CORTIS took first place on Mnet's "M Countdown," which aired on April 30. "REDRED" is the title track of their upcoming second mini-album "GREENGREEN," set to be released on May 4, and was pre-released on April 20. This first-place win was achieved solely based on digital music performance, global social media, fan votes, and broadcast scores, without any album points.

Right after receiving the first-place award, the members said, "It doesn't feel real," and added, "We had many goals and ambitions while preparing, and it feels like we achieved this together with CORE (official fandom)." They continued, "This is an award we've always wanted to receive since our debut," and said, "It's meaningful and we are grateful to have won first place before the release of our second mini-album. This is thanks to the blood, sweat, tears, and love of many people." Some members shed tears of joy but soon delivered a highly polished live encore performance. They also expressed their gratitude once again during a Weverse live broadcast with fans after the show ended.

"REDRED" is a song that metaphorically compares what CORTIS aims for as "GREEN" and what they warn against as "RED." All members participated in writing and composing the song. They also took part in creating the choreography and music video, showcasing their capabilities as a "self-produced group." The "Flapping Ear Dance," which involves drawing an X with both arms or shaking hands beside the ears, gained popularity on short-form platforms. The "M Countdown" stage video released on YouTube on April 23 surpassed 1.6 million views within a week. This stage clip was selected as the "M Ca PICK Stage" for the fourth week of April based on fan votes.

The song's performance on music charts was also remarkable. CORTIS became the first boy group debuting within the last five years to enter Spotify's global audio and music streaming platform's "Daily Top Songs Global" chart, ranking 90th on the April 29 chart and maintaining an eight-day streak on the chart. On Apple Music's "Today's Top 100: Global," they held the 49th position as of April 30, maintaining their rank for four consecutive days. They also held first place for three consecutive days on Spotify Korea's "Daily Top Songs" and for five consecutive days on Apple Music's "Today's Top 100: South Korea." On April 29, they set their personal best on daily charts with Melon (73rd), Bugs (14th), and Vibe (40th).

Interest in the second mini-album "GREENGREEN" is also rising. The number of pre-saves on Spotify reached 985,000 on May 1, nearing the one million mark. Based on this figure, they ranked second on the April 29 "Countdown Chart Global," just behind Olivia Rodrigo.

Since their debut in August last year, CORTIS has been expanding their influence in the domestic and international music markets by establishing a unique identity.
