NiziU(니쥬) 'Sour Grapes' Performance Video

Why Koreans care

The official description identifies “Sour Grapes” as NiziU’s first Korean mini album and dates its release to September 28, 2026, at 6 p.m. KST.

In the Korean comments

One comment reads, in translation, `"ㅎㅎㅎ 아워벌스데이인줄" (roughly, “Haha, I thought it was ‘Our Birthday’”)`, recording an immediate moment of mistaken recognition without explaining the resemblance. Another writes `"넘귀여워 니쥬" (neom gwiyeowo Niziu, “NiziU is so cute”)`; 넘 (neom, “so”) is a casual online shortening of 너무 (neomu, “so” or “very”), which gives the praise a quick, affectionate tone.
