&TEAM 'Good Boy' Official MV Teaser

What happened

HYBE's Japan-based label YX LABELS (home of the group &TEAM) released the official MV teaser for "Good Boy," with the full video slated for 2026-09-24 18:00 KST. The video's own hashtags flag that "Good Boy" is not the single's lead track — that's a separate song, "Mark on Me."

Why Koreans care

The teaser's one Korean lyric line, 숨통을 물고 흔들어 놔 (sumtong-eul mulgo heundeureo noh, "bite down on the windpipe and shake it loose"), sits right after "I move like a beast" — it's a predator sinking its teeth into prey's throat, not a softer phrase like "bite hard." That lands next to "Outta control, in your hand a leash": the song's narrator is a collared animal that's also a beast that could break free, which is the tension "Good Boy" as a title is playing on.

In the Korean comments

The liveliest thread in these comments isn't about the teaser itself but about which song should have been the title track. One commenter writes, in translation, "Postpone the tour and do more Good Boy promotion in Korea... if this had been the title track from the start, how great would that have been" — naming "Good Boy" as the song they wish the label had picked over "Mark on Me." Another goes further, in translation: "I seriously want to ask the agency — after hearing every song, did they really think 'Mark on Me' would do best? Or did they just bury 'Good Boy' completely?" Both comments treat "Good Boy" as the stronger song being passed over for the actual lead single, which matches what the video's own hashtags show.

What the words mean

One comment calls the song "앤팀의 맛을 참 잘살린 노래" (song capturing the group's distinctive signature) — literally "a song that really brings out &TEAM's 맛 (mat)." 맛 (mat, distinctive flavor, signature style, or character) literally means "taste," but in casual fan usage here it means the group's signature flavor or character, not anything about food. The register is affectionate fan shorthand, the kind of word Korean-language K-pop comments use constantly to praise a song for feeling distinctly like the artist.
