NiziU’s “Sour Grapes” Turns Aesop’s Fable Into a Stage Hook

A bright stage with more force

NiziU performed “Sour Grapes” on Mnet’s M Countdown on Oct. 1, introducing the title song in its first Korean music-show stage. 1 The performance was part of the group’s Korean comeback after about a year and six months, a return period noted by Slist and Topstar News. 1 2 Slist says kitschy styling and a forceful performance brought a more intense mood to NiziU’s familiar bright image. 1 Topstar News also highlights powerful movement paired with refreshing charisma. 2 That’s a fun mix on paper: the styling keeps a playful edge while the movement lands with force. 1 2

What the grape move adds

Both Slist and Topstar News single out point choreography shaped like grape clusters; Slist connects it to the song title, and Topstar News says it drew attention and underscored the track’s catchy character. 1 2 The title track draws on Aesop’s “The Fox and the Grapes.” 1 Slist describes the fable’s familiar logic as putting down what cannot be obtained, while both reports say NiziU reframes it around boldly taking choices other people hesitate to make. 1 2 The grape move gives that source a visible cue onstage: the fruit points back to the fable, while the confident premise belongs to NiziU’s reinterpretation. 1 2

Slist reports that comments on the Mnet K-POP performance video included remarks praising NiziU’s growth and saying the song sounded better when seen onstage. 1 Those examples speak to different parts of the return: one to the group’s development, the other to the effect of seeing the song performed. 1

Beyond the M Countdown stage

JYP Entertainment released behind-the-scenes images from the music-video and jacket shoots on Oct. 2. 1 Slist describes vivid-color settings and members moving between playful poses and intense expressions; StarNews specifically mentions V-sign poses and intense gazes. 1 3 The music video was filmed in Taipei, where red, leopard-patterned and leather styling helped project a more mature image. 1 2

NiziU’s “Sour Grapes” was the group’s first mini album presented in Korea and contains five tracks. 1 2 The tracklist also includes “Petal’s Song,” “emoji,” “Into The Dawn,” and “Lullaby.” 1 2 Topstar News describes the album more broadly as exploring familiar materials and emotions through NiziU’s perspective. 2 That album-wide framing sits alongside the title track’s specific fable reference, giving the five-song release a wider context than the stage concept alone. 1 2
