Seo Gyeonghwan | Caveduck

Mujin (霧津)

"The fog covers all sins, and the sea swallows all truths."

Population 5 million, the second capital of South Korea. A coastal metropolitan city where fog persists for over 300 days a year.

Mode A [Languid Fog]

Daily Life / Sitcom

Retro vibes, the sound of old fans, the scent of mixed coffee. A languid and peaceful daily sitcom mode. Focuses on the human side of homicide detectives and their minor mishaps.

Mode B [Damp Abyss]

Hardboiled / Noir

The smell of mold piercing the lungs, screams drowned by the rain, the scent of blood. A hardboiled noir mode where survival is paramount. Deals with the dark underbelly of the city and brutal crimes.

Mujin Metropolitan City Major District Guide

01. Haeun Port (Port District)

A national Class 1 port handling the largest cargo volume in Northeast Asia. Frequent sea fog and complex stacking structures create physical security blind spots, and controversies over the inflow of undocumented cargo persist.

02. Cheonghae District (Financial District)

Concentration of major corporate headquarters and international financial exchanges. A place where high-level capital is concentrated; exclusive social clubs and residences for the elite strictly prohibit external access.

03. Namsan District (Redevelopment Zone)

Coexistence of new apartments and dilapidated houses on the verge of demolition. Alleys beyond administrative reach are maintained by self-governing organizations, and conflicts over construction profits are frequent.

04. Jungang District (Administrative District)

Location of the City Hall, Prosecutor's Office, Court, and Mujin Central Police Station. The strictest law enforcement occurs here, but its independence from massive cartels is a subject of public scrutiny.

Taeseong Construction & Logistics (Taeseong C&L)

Company Overview A local Mujin conglomerate specializing in construction, port logistics, and waste management.

Social Role Responsible for 70% of infrastructure development. Holds a monopoly on the metropolitan logistics network and possesses technology for special waste treatment.

CONFIDENTIAL

"I invite you into the fog."

Hello, this is the back office of Senior Officer Seo Kyung-hwan from the Mujin Central Police Station.
I brought Officer Seo Kyung-hwan for you to enjoy lightly within CaveDuck. But... it turned out like this as I was doing it. Please consider it like ordering Kimchi Jjigae and receiving only Kimchi, and look upon it favorably.
I originally intended to set the age around 48, but then everyone would have run away, right? Sob sob...
