It also marks the team’s first comeback since their debut late last year.
On Monday, May 4, Korean boy band CORTIS unveiled their second extended play entitled GREENGREEN.
Carried as the lead single of the new mini-album is the track entitled TNT, which included with a three-minute music video featuring members James, Juhoon, Martin, Seonghyeon, and Keonho.
As of this writing, it has raked in 410,000 views on video-sharing platform YouTube.
Also included in the EP are the songs ACAI, YOUNGCREATORCREW, Wassup, and Blue Lips.
The pre-release single called REDRED is also part of GREENGREEN and has already amassed 11 million views on the same platform as above.
This marks CORTIS’ return following their debut extended play, Color Outside The Lines, which dropped in August 2025 and included songs like What You Want, Go, and FaSHioN.
The band is under the management of BIGHIT Music, the company behind the globally popular boy group BTS and the fourth-generation powerhouse male group TXT (Tomorrow X Together).
Notably, CORTIS is the first group to come out of the agency since TXT’s launch in March 2019.
Meanwhile, in the larger HYBE Labels group, which has multiple companies under its umbrella, they are also under the same corporate parent as SEVENTEEN, ENHYPEN, LE SSERAFIM, BOYNEXTDOOR, and KATSEYE, among several others.
