We've all been waiting for 'Cosmopolitan's upcoming August issue for one reason and one reason only (okay maybe not really, but...) - their pictorial with the smoking hot cast of upcoming SBS drama 'Scarlet Heart: Ryeo'!

The August issue will be sporting two covers - one featuring the drama's lead couple Lee Jun Ki and IU, and another featuring the whole, main cast. 

'Scarlet Heart: Ryeo', starring Lee Jun Ki, IU, Kang Ha Neul, Hong Jong Hyun, Nam Joo Hyuk, EXO's Baekhyun, Ji Soo, and Yoon Sun Woo, is set to premiere August 29. 

Boy, are they a good looking bunch or what?
