NiziU Releases First Korean Mini Album ‘Sour Grapes’ [Q&A]
경향신문
What happened
NiziU has released “Sour Grapes,” its first Korean mini album. The project follows the group’s second single, “LOVE LINE,” which was unveiled in March 2025 as its first comeback in Korea.
Why it matters
NiziU’s debut produced notable results, including a music-show win just nine days after debut. At the time, its debut album also ranked seventh in first-week sales among K-pop girl-group debut albums. Against that record and the 2025 “LOVE LINE” comeback, “Sour Grapes” is significant as the group’s first Korean release in the mini-album format. It therefore adds a new album format to NiziU’s Korean release history.
