Rookie group Romeo had previously made a great debut with "Lovesick," but looks like they'll be changing their image slightly for their comeback!

They dropped the teaser image for their second mini-album, 'ZERO IN,' and they're going for a more tough street look!  Previously, they were as sweet as candy in matching pastel-colored suits.  Here, they are sure to make more fans swoon with a manlier charisma. How might their sound change, as well?
