Jung Chae Yeon continued, "The members did a great job in teaching me to improve my dancing and singing. I'm always so thankful, and I'm glad that we got to become close through IOI promotions. I hope that we can become even closer. Now IOI's group promotions are over and we are promoting as units. During IOI's group promotions, YMC was very considerate toward us. I will do my best as IOI's and DIA's Jung Chae Yeon so please look kindly upon me. I will greet you all once more as a part of IOI's unit."
