DONGKIZ went for an experimental style in their second set of 'I'MMATURE' version comeback concept photos. 

Unlike their first, 'IMMATURE' version teasers released earlier this week, the DONGKIZ members seem to be exuding a more stoic, thoughtful mood in this set of images. In each individual cut, the photographer uses a projection in a darkly lit room to illuminate the members. 

DONGKIZ's comeback with their 5th single album 'Chase Episode 1. GGUM' is slated for this July 1 at 12 PM KST.
