CORTIS are a five-member South Korean boy group consisting of:<\/p>\n\n\n\n
Martin
James
Juhoon
Seonghyeon
Keonho<\/p>\n\n\n\n
They debuted under BigHit Music in August 2025, making them the label’s next major boy group after BTS and Tomorrow X Together.<\/p>\n\n\n\n
In 2026, their song \u201cREDRED\u201d turned them from promising newcomers into one of K-pop’s most talked-about new groups.<\/p>\n\n\n\n
TikTok named CORTIS its Boyband of the Summer 2026 and positioned \u201cREDRED\u201d at the centre of its K-Pop Summer campaign.<\/p>\n\n\n\n
The group has been built around the concept of a creative crew rather than simply performers executing somebody else’s ideas.<\/p>\n\n\n\n
They have become known for participating in:<\/p>\n\n\n\n
songwriting
composition
choreography
video concepts
creative direction<\/p>\n\n\n\n
That involvement has become a central part of their identity.<\/p>\n\n\n\n
The song uses traffic-light colours metaphorically.<\/p>\n\n\n\n
Green represents the direction the group wants to move toward.<\/p>\n\n\n\n
Red represents things they want to stop or reject.<\/p>\n\n\n\n
The track therefore becomes a youthful statement about deciding what belongs in your life and what doesn’t.<\/p>\n\n\n\n
It’s not exactly subtle.<\/p>\n\n\n\n
That’s part of its appeal.<\/p>\n\n\n\n
The choreography helped enormously.<\/p>\n\n\n\n
One particularly recognisable movement became known as the \u201cwiggle ears\u201d or \u201cflappy ears\u201d dance.<\/p>\n\n\n\n
Short-form videos using the song spread rapidly.<\/p>\n\n\n\n
Even members of BTS, TXT and ENHYPEN engaged with the dance trend.<\/p>\n\n\n\n
That created an ideal K-pop discovery loop:<\/p>\n\n\n\n
song
dance
fan videos
celebrity participation
more song discovery.<\/p>\n\n\n\n
Broadly:<\/p>\n\n\n\n
K-pop
hip-hop
pop<\/p>\n\n\n\n
But describing any modern K-pop group with a single genre is difficult.<\/p>\n\n\n\n
K-pop frequently absorbs:<\/p>\n\n\n\n
rap
R&B
electronic music
dance music
rock
trap
funk<\/p>\n\n\n\n
within the same project.<\/p>\n\n\n\n
\u201cREDRED\u201d leans heavily toward rhythmic, dance-focused pop.<\/p>\n\n\n\n
They aren’t members of BTS or a BTS sub-group.<\/p>\n\n\n\n
The connection is the label.<\/p>\n\n\n\n
Both groups come from BigHit Music.<\/p>\n\n\n\n
That naturally created enormous curiosity around CORTIS from the moment they debuted.<\/p>\n\n\n\n
But sharing a label also creates pressure.<\/p>\n\n\n\n
Every new BigHit boy group will inevitably be compared with BTS.<\/p>\n\n\n\n
The healthiest route for CORTIS is therefore developing an identity that clearly belongs to them.<\/p>\n\n\n\n
Their second EP GREENGREEN arrived in 2026 and performed strongly internationally.<\/p>\n\n\n\n
The group also picked up major awards within its first year, including a Record of the Year grand prize at the 2026 KM Chart Awards.<\/p>\n\n\n\n
That’s unusually fast growth.<\/p>\n\n\n\n

YOUNGCREATORCREW<\/p>\n\n\n\n
Start with \u201cREDRED\u201d if you want to understand the current hype.<\/p>\n\n\n\n
Then move backwards.<\/p>\n\n\n\n
The group’s creative involvement is probably the most interesting part.<\/p>\n\n\n\n
A common criticism of K-pop is that groups can feel heavily constructed by labels.<\/p>\n\n\n\n
CORTIS are deliberately positioned against that perception.<\/p>\n\n\n\n
The members aren’t merely appearing in the end product.<\/p>\n\n\n\n
They’re involved in making it.<\/p>\n\n\n\n
Whether that approach continues as they become bigger will be one of the most interesting things to watch.<\/p>\n\n\n\n
Because music discovery moves quickly.<\/p>\n\n\n\n
By the time an emerging K-pop group becomes globally obvious, the early discovery phase is already over.<\/p>\n\n\n\n
\u201cREDRED\u201d feels like that transition point.<\/p>\n\n\n\n
CORTIS aren’t obscure anymore.<\/p>\n\n\n\n
But they may still be early enough that millions of listeners are only now asking:<\/p>\n\n\n\n
Who are these guys?<\/p>\n","protected":false},"excerpt":{"rendered":"
