CORTIS is dominating across all fronts, proving themselves as this year's breakout rookie.

As of September 18 at noon, the group had already amassed about 2.845 million TikTok followers and 2.546 million Instagram followers—just one month after opening their accounts. Among 2025 rookies, they rank No. 1 in follower growth.

Their debut album is also a hit. Title track "What You Want," intro track "GO!," and follow-up single "FaSHioN" have sparked viral dance challenges, spreading quickly on social media. The members' self-produced videos and unique fashion have further amplified attention.

The impact is reflected in the charts. According to the latest Circle Chart (September 7–13), debut album "COLOR OUTSIDE LINES" ranked No. 2 on the weekly album chart. First-week sales exceeded 420,000 copies, marking the highest debut album sales for a rookie this year on both Hanteo and Circle charts.

On Spotify's "Daily Viral Songs Global," CORTIS also claimed the No. 1 spot—an achievement no other rookie in 2025 has managed. "What You Want" topped the chart from September 1–7, followed by "GO!" leading from September 9–11.

Formed under HYBE's BigHit Music, CORTIS consists of Gunho, Sunghyun, Juhun, Martin, and James, showcasing self-produced songs and choreography.

The group is continuing their hot streak with music show appearances: Mnet's M Countdown on September 18, KBS2's Music Bank on the 19th, MBC's Show! Music Core on the 20th, and SBS's Inkigayo on the 21st.
