Gayoon claimed in an interview with OSEN, "We didn't expect an all-kill of charts, but we've always imagined and wished for it. I can't believe it has actually happened; we're so amazed and happy. We can't wait to perform the song, since we've only revealed the chorus choreography in the music video".

Sohyun continued, "I'm happy that our hard work has produced a fruitful result. I can't wait to be on stage. I'm thrilled that all our songs on the new album are on charts - 4Minute is truly a "music chart gangster"".
