4minute expressed some anxiety about their comeback, saying "Making a comeback after a long hiatus makes us nervous, to be honest." They added, "Even anxious." "Making our comeback in Korea is a big burden for us. While other girl groups worked nonstop, we took a break for a year. They confessed, "Because of this, our biggest worry is that fans might have forgotten us." On their new album 4minute said, "Through this album, we're trying to become closer with our fans. We made the choreography easy so that fans could follow along. We want to be the 4minute that fans want to hear." That's why they picked "Heart to Heart" as their title song - "The song really talks about a girl's emotions. We were really satisfied with that song, it marks the first time that love is the theme of one of our songs. Before that, most of our songs were about one's self." Finally, to close up, they said, "We hope that you receive our new concept with love. From now on, we will maintain our unique colors and show you the different sides of 4minute." 4minute's title track, "Heart to Heart" and their shadow title track "Mirror Mirror" are steadily climbing their way up the real-time charts. In addition, be sure to check out the allkpop review of "Heart to Heart"!
