The girls will be at Bundang's AK Plaza at 7PM KST on February 3 to have a mini concert, to celebrate their MV for "Bboom Bboom" hitting over 15 million views on YouTube. Originally, the girls were going to have a concert for hitting 4 million views back on January 21, but ultimately had to cancel because too many people gathered and they were worried about accidents. This time, the girls will be at a bigger venue.
