EJ - you just posted a clip about the similarity between Jia & Min.  It reminded me of almost all of their radio show appearances, especially if they're comfortable with the host/hostess.  I don't think they know how to just sit there, and politely nod to the music like what's expected out of them as a girl group.  LOL  Especially Min & Jia, but...

Suzy is exactly the same as them.  LOL.

The only one that ever behave is Fei.  LOL
