Whoo, check out actor Kwak Si Yang on the set for a shoot with 'Sure' magazine!

His agency, Starhaus Entertainment, recently posted a behind-the-scenes video of their hunky, tall star looking all fashionable for the shoot.  Although he's full of charisma and chicness when the camera is snapping away, he becomes his normal cute and dorky self once he's speaking to the camera about how the shoot's going.
