The practice of "Trouble maker" was a complete mess. Hyomin couldn't concentrate at all. Everytime her ex girlfriend, Park Jiyeon, would place her hands on her body for the choreography, Hyomin could feel the air around her become almost non existent and her brain become blank, making her for the hundred time mistake the choreography. Hyomin was mad with herself. Why was she still feeling like this? Why couldn't she just wash away those feeling for Jiyeon?
