On the January 25th broadcast of KBS2TV's new hit drama God of Study, girl group T-ara made a cameo appearance, showing up as tormentors of their fellow member Jiyeon (Na Hyun Jung in the drama). I don't want to give away too much of the plot, but you can see from the pictures that the girls are pretty serious. Cute, as always, but serious. Even kind hearted Eunjung looks like she's about to knock the living daylights out of Jiyeon. http://www.youtube.com/watch?v=JBQ0iJdl2EM All of the girls together on set make the already epic drama even better, and although they looked pissed off on camera, at least they seemed to have enjoyed themselves on set.
