The group that doesn’t try to look cool — and that’s exactly why they’re dangerous
K-Pop
CORTIS just dropped the “TNT” MV. It’s a B-side from the GREENGREEN EP. The title track is REDRED. But watching this video makes one thing clear: this group has no interest in looking polished — and that’s exactly what makes them dangerous.
What the Camera Is Saying
Handheld. Extreme close-ups. Rough shaking. Natural light, which means dark frames and bleeding colors. The whole thing has the texture of a VHS tape you found in someone’s basement.
Some shots are out of focus. Some are blown out by the light. Neither is an accident.
There’s a 1971 American crime film called The French Connection — Gene Hackman, handheld cameras, a visual texture that felt raw and immediate in a way that hadn’t been done before. TNT carries that same energy. Not trying to capture something beautiful. Trying to capture something alive.
The Neighborhood Behind the Apartment Blocks
The video opens on old Seoul alleyways. The kind of neighborhood that sits behind the gleaming apartment complexes — the kind that looks like it’s already been marked for redevelopment. Worn buildings, narrow paths, the unfiltered texture of daily life.
Early in the song, the age sixteen is mentioned. This reads like a direct self-portrait — the neighborhood they actually lived in, the years before debut. There’s a shot of them running through an elementary school yard. This isn’t a set. This is just Seoul.
REDRED’s music video involved 500 extras, and it wasn’t entirely clear where they all went. TNT answers that. From start to finish, a crowd of people is chasing CORTIS through the streets. Those people aren’t styled. They’re not performing. They look exactly like the residents of that neighborhood — because they probably are.
Why They’re Being Chased
The MV doesn’t explain it. It doesn’t need to.
Follow CORTIS’s music and the context becomes clear. In REDRED, they declared that what the world calls RED — stepping outside the rules, refusing to fit the existing standard — is exactly what they’re choosing. Sixteen-year-olds from the neighborhood made that choice and started running. The neighborhood comes after them. The world comes after them.
“TNT” isn’t a song about an explosion. It’s about the state just before one — the tension that can’t be stopped, the pressure that’s already building. That’s why they keep running. Not because they’re being chased. Because they’re already about to detonate.
No production set. No special lighting. Just Seoul alleys. Just running.
Why a B-Side Has Its Own MV
TNT is not the title track. B-side MVs are uncommon in K-pop. REDRED crossed 10 million YouTube views in 12 days — that momentum made this possible. 2.02 million pre-orders. Those numbers opened the door.
Once again, the members co-directed with IDIOTS. REDRED was the same — members as co-directors, roaming old Korean shops and streets, channeling raw energy into the frame. TNT is that approach taken further. Less controlled. More immediate.
Why This Group Is Going to Matter
They do what they want. That comes through.
Most K-pop rookie groups debut with something safe — a concept the label has validated, an image the market is ready for. CORTIS went the other direction from day one. Psychedelic rock and boom bap. Self-directed MVs. And now: VHS textures and a handheld camera in a Seoul neighborhood that’s about to be torn down.
The group that has no interest in looking cool ends up looking the most dangerous. TNT makes that case.
