Sang Shik is described as a “wacko secretary” who dreams of being a top diplomat: Good-looking, athletic, and a competent fighter, he is described as “halfway between Jang Geu Rae [of Misaeng] and [spy comedy] Kingsman.” Nara, meanwhile, is a diplomat with strict principles who never does things by half-measures and doesn’t know how to hide even the smallest emotion, who’s described as halfway between the perfect diplomat and a nutjob.
