Cube Entertainment's newest and upcoming boy group Pentagon will finally begin filming their debut music video for their first single! No definite description of the video or single has been reported, but eager fans will be in for a "powerful" debut.

Even though their group name reflects a shape with 5 sides, the rookie group will be debuting as 10 members. Mnet's reality show 'Pentagon Maker' featured the boys' debut journey. Pentagon is the newest boy group from Cube since BTOB, who debuted 4 years ago in 2012. They were set to debut earlier this year, but due to unforeseen circumstances, their debut date had been pushed back.

It has been a long wait and we are looking forward to what sound and image this rookie group will bring to K-pop!
