Chorong said, "Every time we release an album, we tried to incorporate change and growth. We believe it is appropriate for us to exhibit an even more grown and mature side of us especially as it has been six years since our debut, so we paid even more careful attention [to this comeback]."

Eunji explained, "We always try to make great music, but we thought that we want to focus more on the musical aspect and mature a bit more. So rather than a hook-heavy track, we just wanted to make pretty music. Even when we were talking to the composer, we expressed our wish to do music that is more mature and focus more on the music itself. Before, we wanted to do the kind of music that was simply catchy, but nowadays, we said we want to do music that is 'good music.'"
