Park Han Byul and Joo Sang Wook once again left consumers staring perhaps just a bit too long with their sexy ads for�'Bodyguard'.

The underwear brand unveiled its summer pictorial featuring the two endorsement models. The actor and actress have previously teamed up, but they're doing it again, going for a 'cool & light' concept for the summer season this time with their matching green, patterned undergarments.

The pictorial treated both male and female fans to some eye candy with Park Han Byul showing off her amazing figure and Joo Sang Wook putting his abs on display.
