All I remember from both the LTS music video and SMCU Ep. 2 is seeing her face lol
I went back and watched the music video again and Karina has by far the most screen time while Giselle is basically a cameo
SM picks their one to push in every group pre-debut and obviously Karina was their choice in Aespa given the BM teaser is literally just her. But it's interesting to me that they've continued to favor her when Winter is definitely bigger in Korea and Japan and Ningning seems to make the most noise out of the four in the West. Perhaps it is because her Chinese bar buys the most and they want to maintain her selling power?
