CORTIS to drop second mini-album ‘GreenGreen’ on May 4

After making a strong impression on the K-pop scene, CORTIS — a K-pop boy group composed of Martin, James, Juhoon, Seonghyeon, and Keonho — is gearing up for the release of their second mini-album “GreenGreen” on May 4.

BigHit Music confirmed the quintet’s upcoming mini-album featuring six tracks in a press statement, as well as a pre-release single on April 20.

The group also announced their upcoming release on Weverse.

“GreenGreen” comes eight months after CORTIS’ debut mini-album “Color Outside the Lines,” which entered the 15th spot on the Billboard 200 charts. 

The K-pop boy group seemingly hinted at the release of their second mini-album during their NBA Crossover Concert Series appearance last February, where they performed one of its tracks “YoungCreatorCrew.”

“Known for their hands-on creative approach across music, choreography, and visual production, the quintet quickly drew attention for their distinctive artistic voice,” BigHit Music said.

The K-pop quintet caught the attention of casual fans after headlining the opening night of the NBA’s Crossover Concert Series, where they were named “Friends of the NBA.” They were the first K-pop act to lead the event. 

CORTIS debuted in August 2025.

The group’s name is a shortened version of the phrase, “Color Outside the Lines,” expressing their dedication to “think freely” without being bogged down by the expectations of society.
