I thought Soyeon, Qri or Areum (with glasses) will fit the roles as "good" agent while Eunjung fit as "bad" agent.
I don't see Hyomin, Jiyeon or Boram fit any of agent role here lol..
Waiting for some good news here. I hope to see our girls back on screen soon and since it will be only 20 episodes (or so), it wont interrupt their Asian tour schedule this year.. ~>.<~ I really want to watch full member of T-ara whey they're performing on tour.
