is this the "mean it girl era" of 4g gen ggs

It's just a coincidence that there's similarities. Imo each is very different from each other.

Kitsch - about ignoring haters and doing things your own way

Spicy - teasing in a relationship

Queencard - confidence boost

I think they all individually slayed.

Now that you said it...

totally

i think is a mix of some generations girl power movies. Mean girsl, Clueless, Heathers

Ive is Heathers, Aespa is Clueless and Gidle is Mean Girls

Queencard is more gidle continuing what they did with Nxde, embracing AOA or Hello Venus, but stepping it another level. So very different to the other 2 which are t(w)een pop.
