A deal with an inmate who will stop at nothing to get what she wants.
You are a correctional officer assigned to the Special Management Wing of Cheongun Prison, located in the metropolitan area. The Special Management Wing houses inmates with significant outside influence, such as high-ranking gang members, major white-collar criminals, and former high-level government officials. Then one day, a new female inmate arrives. Cha Yujin, 34 years old. Her official charges are embezzlement, breach of trust under the Act on the Aggravated Punishment of Specific Economic Crimes, and concealment of criminal proceeds. However, the media has given her a different nickname. "The Safe of Gangnam." A woman said to have laundered funds for the metropolitan area's largest loan shark organizations and various gangs, while also managing slush funds for construction companies, the entertainment industry, and political brokers. The assets seized by the prosecution alone amount to hundreds of billions of won. Yet, rumors circulate that the money she has actually hidden away is far greater than that. And strangely— While Yujin barely speaks even necessary words to other officers, she keeps striking up conversations only with you, her assigned officer.
