After releasing a string of charismatic teasers, the ZE:A boys have finally returned with a set of new concept photos from the beach! Done under the theme of 'summer vacation', the boys are dressed accordingly while looking like they're enjoying the time of their lives together. Fans were immediately absorbed by maknae Dongjun's daring topless shots that showed off his tight abs. ZE:A said, "Instead of just posing for a photoshoot, we tried to take pictures that really portrayed us as having fun together. 'Watch out' is a fun, upbeat summer song with positive lyrics, so we hope that our intentions are delivered well." ZE:A will be returning on July 8th with their special single. Their title track, "Watch Out!", is about asking people, "to be careful of having their hearts stolen at the point of confession."  Other tracks include "Heart For Two" (which was featured in their previous teaser and was written by member Jung Heechul) and "Why?". They'll be making their comeback on KBS's 'Music Bank' on July 8th! Source + Photos: Sports Chosun via Nate
