Their label said, "They got so much love from 'Expectation' that it's true we were at first burdened about this new song and choreography. Since we worked so hard, the members were confident in the new song, but they're so happy because the reaction was better than expected. We're so thankful for the interest."

Regarding the sexy choreography and concept, the label said, "After the suspenders dance, now it's the nine-tailed fox dance. It's the point choreography of the new song, so they worked on it for a long time. They're not burdened at all by the skin exposure. They're just happy to have a new image. They're working hard with the determination to look even sexier when promoting 'Female President'. As the members are working hard and passionately, please watch over them fondly."

The girls will have their first comeback this week on 'M! Countdown', so make sure you check their live performances out for yourself!
