It's the group's highest-charting single to date by far, easily beating the No. 36 peak of their 2012 debut, Whoz That Girl.
The No. 1 song of the week belongs to ballad king Sung Si Kyung's Christmas single Don't Forget, followed by A Pink who stay put at No. 2 with LUV.
Super Junior's Kyuhyun is still going strong with his solo single At Gwanghwamun, which is back up two spots to No. 3, while rapper Master Wu's Come Here featuring Dok2 and Bobby arrives at No. 8.
Meanwhile, trending girl group AOA continue to show staying power as their latest hit Like a Cat remains at No. 10 for a second consecutive week.
Last but not least is new female soloist Shannon, who arrives at a solid No. 32 with her first single Daybreak Rain. This is quite good for a rookie female pop artist, especially one from a smaller agency like Shannon.
