We reported earlier that T-ara was missing one member during their Bo Peep Bo Peep performance on the 2nd January edition of Music Core. With their rapid rise in popularity in recent weeks thanks to their hit song, fans were quick to spot the absence of Jiyeon. With news that she had visited the hospital recently due to her punishing schedule, fans were worried to see her missing this afternoon. But fans can put their hearts at ease because Jiyeon was just busy with her filming for God of Study which will debut in two days time on 4th January through KBS2TV. To make sure fans don't miss her and to keep them updated, Jiyeon uploaded a few BTS photos from her drama filming to her Cyworld. Two of them were with her co-stars, Lee Hyun Woo and Lee Chan Ho while the 3rd picture (see top) sees her blowing her nose, showing that she was still recovering from her illness. We hope she takes good care of herself. After all, she's still only 16.
