I was actually hoping someone would mash them together so I can watch the dance scenes without having to suffer through the rather boring episodes.
I tried to reach EP4 (?) for that blonde girl dancing, but I just couldn't even handle the first episode.

I saw some other clips and they looked pretty. But how often are scenes like that included?
Youtube is not showing much when I type in some search parameters for this show. It only shows the blonde girl dancing on the street and then 2 sisters(?) that look rather similar dancing next to each other in costumes and once while training/showing off. That did indeed look really pretty and very modern and hip-hoppy, which is really cool to look at.
Swinging their bodies and making the wavy-dance moves and all that jazz - k-pop style.

What I'm trying to say is, it didn't look like the usual "Idol dancing" but more like actual hip-hop or at least pop.
