It's D-1 to ONF's upcoming summer album titled 'POPPING!'

Leading up to this comeback, ONF has been releasing a range of teasers from highlight medley to sci-fi themed MV teasers. With just one day left to the final release of the album, ONF uploaded a surprise teaser short clip on their official Twitter account. 

In the short clip, the group's leader and main vocal Hyojin is seen approaching the camera and covering the lens. However, what caught fans' attention was the lip ring seen on Hyojin, among the other common accessories. 

Meanwhile, ONF will be back with their summer album 'POPPING' on August 9, 6PM KST. Are you looking forward to it?
