The group's new song "Rough" has dominated multiple charts since its release, achieving the first perfect all-kill of 2016 and earned them many well-deserved awards on music programs. But their continuous, steady rise doesn't end there. The girls are so popular these days that "Glass Bead," a song that they released over a year ago is surging back up the charts once again!

"Glass Bead," the group's debut track which was released on January 15 of last year, has entered Melon's top 100 this past February 7! It's an incredible feat for a song that is over a year old to be climbing the real-time charts once again, as the charts typically represent songs that were released recently. 

Congrats girls on all your success!
