Rookie group HALO's OOON shows off his abs in new teaser image

HALO are heating things up for their upcoming debut with a swoon-worthy teaser image of OOON (Oh-Oohn)!


As the leader, OOON was first to go shirtless and definitely had nothing to hide with his toned abs. The teaser image is titled, "Can You Hear Me?", which is most likely the title of a track from their upcoming single album.

Get your hearts ready for more teaser images coming up ahead of HALO's debut later this month!
