BIGHIT’s Rookie Powerhouse CORTIS Just Dropped Their First-Ever Comeback Date — And K-Pop Is Paying Attention

Less than a year into their career, CORTIS is already making their first comeback — and the K-pop world is watching closely. BIGHIT MUSIC’s newest boy group has officially announced that their second EP GREENGREEN is on the way, complete with a two-phase release strategy that’s building anticipation perfectly.

CORTIS GREENGREEN Comeback — All the Key Dates

Who Are CORTIS?

If you haven’t caught on yet, CORTIS is the group K-pop fans have been quietly buzzing about since August 2025. They debuted as BIGHIT Music’s newest boy band — the label’s first new boy group in six years since TXT, and only the third since BTS debuted. That lineage alone made them one of the most anticipated rookie acts of the year.

The group blends pop, hip-hop, and experimental elements, and gained early attention for their performance skills, self-produced content, and strong rookie-year sales. All five members earned credits on their debut project — a rare and impressive feat for a group so new.

Their name says it all: CORTIS is short for “COLOR OUTSIDE THE LINES,” meaning to think freely and break free from the world’s established standards.

Why GREENGREEN Is a Big Deal

For a group barely six months old, dropping their first-ever comeback is a genuine milestone. The two-phase rollout — pre-release title track on April 20, followed by the full EP on May 4 — is a smart strategy that gives fans two moments to rally around, builds streaming momentum, and keeps the group in the conversation for weeks.

CORTIS amassed 1 million TikTok followers within six days of launching their official account, and their debut MV trended across 11 regions on YouTube. GREENGREEN arrives with that momentum firmly behind them — and a global fanbase (called COER) that’s been waiting for exactly this moment.
