Here's a fun and simple way to cool off this summer! (If you're in a region where it's summer right now, that is!)

The boys of ONF have released another special set of teaser photos for their upcoming summer popup album, 'Popping'! In this set of photos, the ONF members come up with an interesting way of chasing away the summer heat - by holding a handful of ice cubes! Each of the members' bright, pure smiles are sure to put a big smile on your face as well!

Meanwhile, ONF's upcoming special mini album 'Popping' includes a total of 5 tracks, including a title track of the same name. The group's full comeback is slated for August 9 at 6 PM KST!
