CORTIS is preparing for their first-ever comeback with the second EP "GREENGREEN."

The BIGHIT MUSIC rookie boy group announced their comeback schedule on March 6, marking a significant milestone in their young career. The rollout begins with a pre-release of the EP's title track on April 20 at 6 p.m. KST, followed by the full EP release two weeks later on May 4.

This comeback represents CORTIS's first return since their debut, making it a highly anticipated moment for fans who have been waiting to see how the group will build on their initial release. The "GREENGREEN" EP will serve as their sophomore project under BIGHIT MUSIC's roster.

The strategic two-week gap between the title track pre-release and full EP drop follows a common K-pop promotional pattern, giving fans time to digest the lead single before experiencing the complete project. This approach often helps build momentum and allows groups to maximize their promotional impact.

While specific details about the EP's tracklist, concept, or additional promotional content haven't been revealed yet, the announcement itself signals CORTIS's commitment to maintaining an active release schedule as they establish themselves in the competitive K-pop landscape.

The timing of their comeback places them in a busy spring season, with many groups planning releases around the same period. CORTIS will need to distinguish themselves among established acts and fellow rookies all vying for attention during this competitive timeframe.

Fans can expect more details about "GREENGREEN" to emerge in the coming weeks as the April 20 pre-release date approaches. The group's debut showed promise, and this comeback will be crucial in determining their trajectory as they move forward in their career under BIGHIT MUSIC's guidance.
