In the midst of busy preparations for their comeback, SISTAR's new concept for their third single�was leaked. Their agency, Starship Entertainment, stated, "The concept of their title track, 'How Dare You,' was supposed to be a sporty feminine look that exuded a cold, city-like feel. We tried to release the concept with the music video and the album, but the pictures containing it were leaked. To girl groups, fashion concepts are just as important as the music. Because of this leak, we have planned to release the concept photos earlier than planned." SISTAR has already delayed their comeback album due to the Yeonpyeong Island skirmish.
