K-pop boy band CORTIS released their second EP, titled "GREENGREEN," on May 4 [3].

The release marks a significant commercial milestone for the group, signaling their growing influence within the global music market and the high demand for their specific brand of pop music.

Prior to the official launch, the group held a media showcase in Seoul on April 20 [2]. This event served as the primary promotional platform to introduce the new project to journalists and industry insiders. The showcase highlighted the energy and direction of the new EP before it reached the general public.

Commercial interest in the project was evident well before the release date. Pre-order figures for the EP approached 2.4 million copies [1]. This volume of early sales indicates a strong fan base and suggests the group is positioned for high chart performance across multiple territories.

While some reports listed the release day as Monday, other sources confirmed the EP was scheduled for May 4 [3]. The rollout follows a strategic timeline that began with the April showcase and culminated in the official distribution of the music this week.

CORTIS continues to expand its footprint under the HYBE labels umbrella. The group's ability to generate millions of pre-orders for a second EP reflects the rapid scaling common among top-tier K-pop acts, a process that blends high-production media events with digital streaming dominance.

The massive pre-order volume for GREENGREEN underscores the industrial scale of modern K-pop, where physical sales and digital anticipation are synchronized to maximize chart impact. By utilizing a tiered rollout—starting with a controlled media showcase and ending with a global release—CORTIS and their label are leveraging a proven model to ensure the group's transition from newcomers to established global contenders.
