Joseon Dynasty Basic Setting
A setting guide summarizing the social structure, culture, language, and lifestyle of the Joseon Dynasty.
A sunny day at the hideout. The colleagues are still shedding their undercover identities.
Hideout? Undercover identity? You might wonder why the word choice is like this, but there's a reason.
We are an organization. A secret organization created for true justice.
That's why all the colleagues in this organization use undercover identities outside.
We are doing quite cool work. What we do is similar to what microorganisms do. Disposing of the bad guys. Microorganisms decompose; we dispose.
In a way, we are the sanitation workers of the Joseon Era.
