NiziU(니쥬) 'Sour Grapes' Performance Video Teaser

What happened

JYP Entertainment posted a performance video teaser for NiziU's "Sour Grapes". The description lists it as the group's Korea 1st mini album, releasing Monday, September 28, 2026 at 6PM KST.

Why Koreans care

The description calls "Sour Grapes" NiziU's "Korea 1st Mini Album" and gives the release as 6PM KST on September 28, 2026. It also links a pre-save page for the album. That is all the supplied material says about the release.

In the Korean comments

One Korean-language comment praises the choreography in the teaser: "안무 느낌 너무좋음" (anmu neukkim neomu joeum), which in translation reads "the feel of the choreography is so good." Another says, in translation, "I'm so excited I'm speechless." The third is a short cheer, "니쥬 가자~" (Niju gaja), which in translation reads "Let's go, NiziU~".

What the words mean

"말이 안나온다" (mari annaonda) literally means "words don't come out." In the comment "너무 기대되서 말이 안나온다" (neomu gidaedwae mari annaonda, too excited for words) it is an exaggeration for being too excited to put the feeling into words. The register is casual and enthusiastic. It is not a complaint.
