K-Pop Madness 2017 is a month-long competition on PopCrush to determine the best of the best of South Korean boy bands and girl groups.

UPDATE: This round is now over. Find out who won!

To say that K-pop fans are dedicated would be an understatement of the century: the semi-final round of PopCrush's search to determine the best of the Korean boy bands and girl groups has officially ended after 20 million votes (!), and we're down to the final round for each bracket. For the ladies? It's f(x), who moves on after a spirited fight to the finish against Girls' Generation, ultimately moving on with 50.62% of the vote. And in the other corner, it's Apink, who absolutely wiped the floor with their competition (sorry, SISTAR!), moving on with an incredible 90.69% of the vote. But we have a feeling this round won't be quite as easy.

It's time for the final round.

Apink are K-pop veterans at this point, delivering hits since their 2011 debut. Their most recent release, December's Dear, included three duets sung by pairs of the girl group's members, as well as title track "'Cause You're My Star."

Electro-troupe f(x) made their big debut all the way back in 2009, supplying four full-length studio albums ever since 2011’s Pinocchio. After releasing “4 Walls / Cowboy” in Japan last year, the girls are expected to return with a South Korean comeback later this year.

The battle starts now: place your vote between Apink and f(x). This round ends on March 31 at midnight.
