In what can only be described as a thunderous debut, BIGHIT MUSIC’s new boy group CORTIS has taken the K-pop world by storm with the release of their first EP, COLOR OUTSIDE THE LINES.
Since its launch on September 8, 2025, the group has not only captured the attention of fans across the globe but has also shattered records — proving that they are more than just the next big thing; they are a force to be reckoned with.
According to data released by Hanteo Chart, CORTIS’s debut album sold a jaw-dropping 436,367 copies in its first week (from September 8 to 14), officially making it the highest first-week sales for any debut album by a group in 2025.
This milestone is a significant achievement in an industry that sees dozens of idol group debuts each year, and it positions CORTIS as a top-tier rookie act right out of the gate.
A Name That’s Already Echoing Loudly
The group’s name, CORTIS, was already generating buzz long before their official debut — largely due to their connection with BIGHIT MUSIC, the powerhouse label behind global sensations like BTS and TXT.
Expectations were high, and fans eagerly anticipated the group’s concept, sound, and overall identity.
Still, few could have predicted the level of immediate success that CORTIS would attain in just their first week.
Their debut EP, COLOR OUTSIDE THE LINES, features a blend of fresh, experimental sounds that match the group’s youthful energy and bold messaging.
Rather than playing it safe, CORTIS went with a strong creative identity from the outset — emphasizing artistry, individuality, and a refusal to conform.
The title of the album itself suggests a breaking away from norms and a willingness to push boundaries — something that’s already resonating with fans and critics alike.
A Standout Track That Defines Their Style
While the EP contains multiple tracks, it was their B-side track “FaSHioN” that initially took the spotlight, launching alongside a stylish, visually striking music video.
The song’s funky rhythm, genre-blending production, and confident lyrics highlight the group’s versatility and charisma.
Paired with fashion-forward visuals and choreography that pulls no punches, FaSHioN became an instant fan favorite and helped drive both streaming and album sales.
Even though it’s not the title track, “FaSHioN” has effectively become a statement piece for CORTIS — a display of their distinct artistic identity.
Their debut stage on SBS’s “Inkigayo” further solidified their impact, with a performance that showcased the group’s exceptional synchronization, stage presence, and charisma.
The buzz surrounding the performance has only fueled more curiosity and admiration for the group, particularly from fans who are eager to see how their style evolves.
Breaking Records and Hearts
CORTIS’s debut album has already overtaken the previous 2025 record held by Hearts2Hearts, making them the most commercially successful rookie group to debut this year.
This record is particularly impressive considering the competitive nature of the current K-pop landscape, where both new and veteran groups are constantly vying for attention across multiple platforms.
Achieving over 430,000 album sales within just seven days is no small feat, especially for a brand-new group.
It reflects the strength of their pre-debut promotions, the strategic backing of BIGHIT MUSIC, and most importantly, the group’s inherent talent and appeal.
In an era where first impressions can make or break careers, CORTIS has made theirs unforgettable.
What Sets CORTIS Apart?
A major factor in their fast rise is the distinct identity that CORTIS brings to the table. From their fashion-forward styling to their unconventional music video concepts, they’re clearly targeting both domestic and global audiences with a sophisticated image that balances youthfulness and maturity.
Additionally, fans have praised the group’s artistic concept, with COLOR OUTSIDE THE LINES being interpreted not just as a title but as a mission statement.
It represents a commitment to authenticity, experimentation, and individuality — traits that are increasingly valued in the global music scene.
A Promising Road Ahead
Given their debut momentum, it’s safe to assume that CORTIS is not a flash in the pan. With their first-week record in hand, the group is now expected to ramp up promotional activities, including music show appearances, variety shows, and international interviews.
If their debut performance on “Inkigayo” is any indicator, they have both the skills and star power to back up the hype.
Fans and industry insiders alike are eagerly watching what comes next — whether that’s a follow-up single, a world tour announcement, or more insights into the members’ individual talents and stories.
