It seems like there has been a push away from the traditional pop song structure, particularly with Aespa's rise in popularity. This song has not one, not two, but three choruses.
Chorus 1: the whisper speaking
Chorus 2: "I'm Athletic girl"
Chorus 3: "Change Up I Want it"
And the way the song works, for the first "chorus" block we get choruses. For the 2nd "chorus" it's choruses 2 and 3. Then for the final one, it's parts 1 and 3 (with chorus 2 spoken at the end which is a callback to the introduction).
Personally I really like it. It still sounds like a cohesive song and instead of one catchy bit, there's three. It would be cool if H1-key keeps this structure in their songs and makes it their "thing" would you like other groups to release songs like this?
