ONF will be joining a list of groups that'll be making a comeback in early-June. Before that takes place, however, another batch of individual teaser images has been released for fans to check out. Much like their previous photos, they highlight the clear blue sky in the background once again. Check out all the images below and let us know what you think of the concept so far.

Meanwhile, ONF will be making a comeback with their 2nd mini album 'You Complete Me' on June 7. Stay tuned.
