Seven member group, Rainbow, recently made a successful comeback with their single A. In an interview with Sports Chosun, Rainbow revealed, "It's a relief that 'A' is receiving so much attention. We are delighted that our schedule is packed all week." They also added, "The truth is, we did not have many schedules last time. All we had were the 2 to 3 days of music programs. However, after we began promoting 'A', we are busy throughout the week. We are not only getting calls from music programs, but also from variety programs as well." The members expressed their gratitude and said, "After promoting Gossip Girl, we took a very long break. We made this comeback after about 7~8 months. We did not know that we would be resting for this long. We have been wanting to stand on stage for such a long time. We were very nervous preparing for the comeback. It is such an honor and we are so glad that we can perform on stage again. We like having a busy schedule more. Even when we cannot sleep, we forget that we're tired." Rainbow will promote A throughout the month, and is planning on releasing a new song in October.
