you're probably right, the girls just left and Hara naturally fits in.
i really like how Hyomin is not a folding screen anymore, and i love her moments when she starts naming things.
on Sori, i really pity that girl. shes talented and definitely can dance, but i guess she's just now entertaining enough. maybe she get advice from Hyomin and stick to a popular G7 from now onwards.
ps. really love the Hara and Hyuna hug. teacher and student re-unites! haha.
