QWER announced fan voting on two unreleased songs. A full video arrives September 6; a listening pop-up runs September 7–13 at Heights Exchange in The Hyundai Seoul, with online and offline voting planned afterward. The two songs have different moods, and the video previews members debating their preferences. Reactions from early listeners including SeeYa, RESCENE’s Minami, Kim Eana and Chimchakman are also planned. The promotion lets fans hear the unreleased music before voting.
