CORTIS “TNT” MV Explained — Old Seoul Alleys and Raw Energy

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.

UNCHILD Debut: From “Haeun’s Group” to a Real Team

The group that was called “Haeun’s girl group” before a single song dropped

K-Pop

UNCHILD debuted on April 21 under High Up Entertainment — the label behind STAYC. Six members. Debut single: We Are UNCHILD.

But the reason this group started getting attention wasn’t the music. It was a name. Na Ha-eun.


“Haeun’s Girl Group”

The youngest member, Haeun, is better known in Korea as Na Ha-eun. In the late 2010s, she became a household name as a child YouTuber — a “dance prodigy” who went viral during stage transitions at the Melon Music Awards between 2017 and 2019. She appeared on Star King and K-Pop Star 4. The whole country knew her face before she was a teenager.

Before a single note of UNCHILD’s music was public, the group had already been labeled: “Haeun’s girl group.”

The members acknowledged the weight of that. Evon said she felt Haeun had carried that pressure more than anyone.

They debuted under that shadow. And then the first week’s handmic live performances landed — and the reaction shifted.

“Solid.” “They can actually sing.”

The attention that started with one name began moving toward the group as a whole.


What UNCHILD Means

UNCHILD is a compound: UN + CHILD. “UN” as a prefix that inverts the ordinary. “CHILD” as someone who refuses to be defined by any existing standard.

Leader Heekie explained it at the showcase: “It might feel unfamiliar at first — but we wanted to show something that’s purely ours.”

The name itself is a declaration. We’re not following the existing formula.


The Sound and the Look

Watch how UNCHILD translates this sound into visuals.

The title track “UNCHILD” combines electronic pop with garage sound and psychedelic elements — a rough electric guitar riff layered over electronic textures, building to a hard drop. The official description is one line: “Same old rules? We choose freaky.”

The music video opens in a subway, introducing each member’s personality, before cutting to a school setting in a punky, high-saturation uniform aesthetic. That visual choice stands out. The current direction in K-pop has been moving toward desaturated, muted visuals. UNCHILD went the opposite way.

Members Heekie and Haeun contributed to the choreography directly.

The Bias List noted that the repeated chant of “We are UNCHILD” risks feeling like an advertising slogan — but the instrumental pushes forward with enough rock texture to back it up. Their assessment: if this sound develops further, UNCHILD could become a genuinely distinct voice in the girl group scene.


Korea vs. Overseas

In Korea, the “Haeun’s girl group” frame was the entry point. The live performance shifted that quickly.

Overseas reactions have been more immediately enthusiastic. High-saturation visuals, a sound that doesn’t fit the current K-pop template, and a higher ratio of Korean lyrics in the track were all noted positively. Within two weeks of debut, reaction videos were appearing not just in English but in Spanish.

One comment captured the overseas mood well: “Wow, very surprised by them! Interested to see how their sound evolves!”

That gap in reaction isn’t confusion — it’s a signal. A signal about potential.


Members

  • Heekie — Leader, Main Rapper
  • Yeeun — Lead Vocalist, Center
  • Tina — Lead Dancer, Sub-Vocalist (China)
  • Ako — Sub-Vocalist (Japan)
  • Evon — Main Vocalist
  • Haeun — Main Dancer, Maknae

High Up’s first multinational girl group since STAYC: four Korean members, one Japanese, one Chinese.


Why Watch Now

“Haeun’s girl group” was the starting point. What the stage showed was something different — a team moving faster than expected past the frame that was built for them.

They started in one member’s spotlight. They’re building their own identity now. That’s the moment worth watching.
