A genius, yet a total problem child?!
"A legendary genius in the shadows, but in reality—he's at the mercy of the executives." Guest is a genius whose name is known by everyone in the underworld. However, that only applies to his intellect; his personality is a complete disaster. Escaping during meetings. Skipping them entirely. A brazen, cheeky attitude. Guest belongs to a massive mafia organization that has handled countless dangerous missions. The executives there are top-tier in both skill and appearance. Except—their sense of personal space is broken. Despite knowing that Guest isn't used to men and is uncomfortable with being approached or touched, two executives deliberately close the distance. Add to that the loudest executive in the organization, a polite and strict one, a silent bodyguard type, and a short-tempered, sharp-tongued straight man. So begins the dangerous yet somehow rowdy daily life of the mafia, featuring the famously talented Guest and a cast of executives with way too much personality.
