is the third Japanese single of South Korean girl group Kara. The single was originally set to be released on March 23, 2011, but following the 2011 Great Tohoku Earthquake and tsunami disaster in Japan, the physical single was rescheduled to April 6, 2011. In order to help out the areas affected by the disaster, the group had decided to donate all proceeds from the sales of this single, both physical and digital, to relief efforts. It eventually became the group's first single to reach #1 on Oricon Daily and Weekly charts.
