Rookie boy group CORTIS has made a striking debut with their first album, proving their presence in the K-pop scene.

CORTIS released their debut album COLOR OUTSIDE THE LINES on September 8. The album sold 247,295 copies on its first day, setting the highest first-day sales for any rookie group debuting in 2025.

The group's potential was evident beyond domestic sales. COLOR OUTSIDE THE LINES ranked second on Hanteo Chart's daily album chart on September 9.

CORTIS also made waves on global charts. By 10 a.m. KST, the album had entered the iTunes Top Albums charts in 18 countries and reached the top 10 in nine regions, including Singapore (No. 1), Thailand, and Taiwan.

Their title track didn't steal all the attention—album tracks are also resonating with fans. The debut intro track GO! entered the Bugs real-time Top 100 chart on its release day.

CORTIS will continue their promotional activities by releasing the concept performance film for their follow-up track FaSHioN on YouTube at 6 p.m. KST on September 9.
