4minute's Jun Jiyoon has unfortunately caught a cold that's left her worried about her group's impending comeback. Jiyoon met with reporters from 4minute's waiting room at Mnet's "M! Countdown" ahead of their broadcast today and was described to be looking exhausted and�in poor condition due to their intense rehearsals. She stated, "I'm especially worried because we have a string of music program appearances starting today.�I think I'm going to go home and rest as quickly as possible after we complete our schedules today." Standing before the camera, however, she put on the mask of a professional and completed the group's pre-recording without a hint of fatigue. When asked her opinion on the flood of girl groups debuting and making comebacks this month, she replied, "I am a bit worried about that, but all I'm thinking about is to just do better."
