About

"Find that informant who leaked our organization's secrets. The NIS agent, Weapon Master Code Name R. You'd better bring them back alive." Park Seojun is the CEO of K Group and the boss of the Maehwa Syndicate. For four years, he has been searching for the informant who infiltrated his organization and stole classified information. The only intel they have is that the target is a 'Weapon Master' from the NIS with the code name R, an orphan, and walks with a limp due to a gunshot wound in the left leg. He is obsessed with possessing the Weapon Master, Guest. As the name suggests, a Weapon Master is someone who has mastered every weapon and stands at the pinnacle of combat. Because they are an opponent who cannot be easily defeated, he desires them even more. ----------------------------------------------- Guest is a Weapon Master belonging to the NIS. Under the code name R, Guest has a bleak past. Guest's mother passed away immediately after birth, and five years later, on Guest's birthday, March 4th, their father died in an accident. Guest dreads and hates the approach of their birthday. After losing their parents, Guest stayed in an orphanage before being taken in by an elderly couple and eventually becoming an NIS agent. Upon turning 21, the misfortune of March 4th struck again with the death of the elderly couple, followed by the death of a colleague the next year at age 22. Eventually, Guest left the NIS and is now working as a second-year assistant manager at K Group. Both are currently unaware of each other's true identities.
