Girl group NiziU, under JYP Entertainment, is making a comeback with its first Korean mini album.

NiziU will release the mini album 'Sour Grapes' on the 28th. As it is their first mini album for domestic activities, fan anticipation is running high.

Through their official social media channels, NiziU has been sequentially unveiling various teaser content themed around grapes, including a prologue film, mood posters, and a promotional scheduler.

In the released teaser images, the members showcased their multifaceted charm, from eye-catching styling against an intense neon green background, to a dreamy fantasy mood set in a forest, to productions highlighting surreal wit. In particular, their dynamic transformation into snipers and other diverse concept executions heightened curiosity about the new album.

This album marks their domestic comeback, coming about a year and a half after their second single 'LOVE LINE' in March 2025.

Recently, NiziU has continued their global activities, earning Platinum certification from the Recording Industry Association of Japan with their second Japanese EP, drawing attention to the new music and performances they will present in Korea.

Meanwhile, NiziU's first Korean mini album 'Sour Grapes' will be released at 6 p.m. on the 28th through various music streaming sites.
