BTS '2.0' MV Behind the Scenes

What happened

BTS filmed behind-the-scenes footage for their "2.0" music video and ended up reminiscing about their 2016 breakout era mid-shoot. The clip, uploaded on the group's own channel BANGTANTV under the title "2.0" MV Behind the Scenes, shows the members debating dance counts, singing a Korean New Year folk song, and joking about a mismatched haircut before wrapping the shoot.

Why Koreans care

The clip leans hard on 2016 nostalgia: members argue over whether their comeback that year was 'I NEED U,' 불타오르네 (Bultaoreune, 'Fire'), or 피 땀 눈물 (Pi Ttam Nunmul, 'Blood Sweat & Tears') — three back-to-back title tracks that marked BTS's turn from a struggling rookie act into a mainstream sensation, so mixing them up becomes a joke about how much time has passed. One member jokes it feels like they're about to win 신인왕 (sinin-wang, the 'Rookie of the Year' title-track award), a line that only works as self-deprecating humor because all seven are now well over a decade into their career — underlined by the shoot itself being dated 2026, a full ten years after the songs they're debating. The group also breaks into "까치까치 설날은" (Kkachi kkachi seollan-eun, a well-known Lunar New Year children's song) and deliberately fumbles the lyrics for a laugh, a reference any Korean viewer catches instantly but a foreign viewer would likely miss.

In the Korean comments

Several commenters (fandom) highlighted the contrast between the finished MV's polished, cool image and the members' goofy energy on set; one top comment put it as: "This MV is so genuinely BTS — hip-hop, cool, and both visually and musically classy and perfect, yet somehow it still has that down-to-earth charm from the seven of them looking like muddy little puppies." A smaller, joking minority (fandom) asked for the behind-the-scenes footage to be extended, writing: "Please add another zero to the end — I want it to be 70 minutes long, haha." The majority sentiment across comments was relief and nostalgia that the group's comedic, unpretentious side hasn't changed, captured in comments like "It's so nice to see BTS still not holding back on the comedy" and "Still working hard, still hilarious — I missed this side of BTS so much... you guys are truly the best."

What the words mean

A foreign viewer would likely misread 똥강아지 (ttong-gangaji, literally "poop puppy") as an insult; in Korean it's actually a common term of affection for someone endearing, similar to calling someone a "little rascal," so the comment describing the members as muddy little puppies is pure affection, not mockery. Likewise, the sudden burst of "까치까치 설날은" (Kkachi kkachi seollan-eun, a well-known Lunar New Year children's song) mid-shoot can look like a random non sequitur to outsiders, when it's actually a deliberately botched sing-along to a rhyme every Korean grows up with, played for laughs rather than a genuine mistake.
