NiziU(니쥬) 'Sour Grapes' Highlight Medley

What happened

JYP released a highlight medley previewing NiziU's first Korean-language mini album, "Sour Grapes," which came out September 28, 2026.

In the Korean comments

One commenter's reaction is a specific memory callback: in translation, it reads, "When did they grow up like this. In my memory they're still doing the 줄넘기 (jullomgi, jump-rope) choreography while singing..." — a reference to the jump-rope-style arm motion from NiziU's earlier group choreography, which this commenter is contrasting with how the members look now. Another commenter makes a direct preference statement about this same release, saying in translation, "Personally, I like the album tracks much more than the title track."

What the words mean

One comment reads, in translation, "The NiziU team always 열일 (yeolil) — I'm drawn to track 2." 열일 (yeolil, fan slang: diligent hard work) looks like it could mean "ten things," but it's fan slang shortened from 열심히 일한다 (yeolsimhi ilhanda, "works hard/diligently"). It's a casual, affectionate way fans praise idols for their work ethic, not a literal count of anything.
