ILLIT's New Choreo, an Old Song Name? Fans Joke About a STUDIO CHOOM Label Mix-up

Clicking a new choreography teaser ought to be simple. But one fan said its thumbnail named a much older ILLIT song instead. The replies turned the reported inconsistency into a running joke rather than a technical incident report.

A Reddit user wrote on October 26 that the STUDIO CHOOM teaser thumbnail appeared to say 'Lucky Girl Syndrome' although the opened video displayed 'You're Under Arrest'. A Korean fan post from the same day linked the official teaser, and STUDIO CHOOM's full 4K performance released on October 27 is titled 'You're Under Arrest'. We could not independently verify that all users saw the same thumbnail or confirm its editing history.

The humor comes from colliding the group's old 'Lucky Girl Syndrome' name with its 2026 song. Fans wondered whether the screen had changed or cached differently and jokingly guessed at copy-and-paste. Such guesses are not evidence of how the producer actually uploaded the asset.

The October 26 Reddit replies contain three recognizable patterns: users comparing different screen states, jokes that the channel loves the older song too much, and guesses about a copy-and-paste oversight. On the separately released official performance page, Mnet Plus users praised the choreography and song. These are two different comment contexts, not one representative poll.

'Lucky Girl Syndrome' is an earlier ILLIT song. 'You're Under Arrest' belongs to the group's October 26, 2026 'BREAK EVEN' release. Unlike broader reviews of the new music or video, the focus here is how fans react to an apparent labeling mismatch in the promotion.

Sources checked were the October 26 Reddit claim and comments; the Korean fan post linking the official teaser; STUDIO CHOOM's October 27 4K upload; and the performance title and comments on Mnet Plus. An October 30 third-party tracker displayed roughly 3.66 million views and 107,000 likes for the full video. These are third-party snapshot figures, not verified live YouTube counts. No official explanation of the alleged thumbnail mix-up was located.

If the channel later clarifies what happened to the thumbnail, its explanation can replace speculation. For now, both the official teaser and full performance are provided so readers can check what content the joke refers to.
