CORTIS entered the top 4 of all-time rookie debut albums. On September 8, CORTIS released "Color Outside the Line." According to Hanteo Chart, the album sold 436,367 copies within a week of its release. This is the highest initial sales record among groups that debuted this year. Additionally, it ranks as the 4th highest first-week sales for a K-pop group debut album in history.

The agency stated, "CORTIS is a team without members from audition programs or previous debuts," adding, "Considering this, the achievement is very remarkable." The album sales of CORTIS demonstrate their potential as a debut group.

They are also standing out on music charts. CORTIS entered three songs on the Korean Apple Music "Today's Top 100" chart. The intro track "GO!" ranked 4th, the title track "What You Want" ranked 8th, and the follow-up song "FaSHioN" ranked 10th. They are achieving multi-hit success.

In particular, "What You Want" held the top spot on Spotify's "Daily Viral Songs Global" chart for a week straight. "GO!" maintained 1st place for three consecutive days, gaining popularity. CORTIS is gaining attention as the group launched by BigHit Music about six years after BTS and TXT.

The growth of CORTIS is regarded as an example showing the potential of rookie groups in the K-pop market. From the early stages of their debut, they have recorded strong album sales and music chart performances, raising expectations for their future activities. Attention is focused on the impact CORTIS's future path will have on the K-pop industry.
