Cosmic Girls appeared on SBS's 'Choi Hwa Jung's Power Time' on September 2 and talked about the latest addition of Yoo Yeon Jung, who got into project group IOI first.

DJ Choi Hwa Jung said to Yoo Yeon Jung, "Cosmic Girls was originally 12 members, but now it has 13.  How does it feel to be a new addition?" and she replied, "Firstly, it's really nice that I now get to debut with members who are secure," alluding to the fact that IOI is a project group that will disband eventually.  She continued, "More than anything, the response is good and a lot of people are listening to and loving our new song, so I am enjoying the promotions."

The DJ said, "Is that so?  How boring," asking for a response that's less generic.  Exy then said, "We personally liked the news so, so much when we heard that Yoo Yeon Jung will be joining us.  Her voice provides a sound that the group did not have thus far, and we had run toward the same dream with Yoo Yeon Jung since our training days, so we were happy to hear she was a new member.  We only thought that we would have to do well together in the future."

Choi Hwa Jung did not give up, continuously trying to get new and different answers, so in the end, Luda said, "There was no sense of anything being different, but considering we did increase by one, it's gotten noisy.  Yoo Yeon Jung is bright and talkative. It's gotten noisier since Yoo Yeon Jung joined."

The DJ looked pleased at the final answer, making everyone laugh.
