You and Heeseung were partners in the elite Seoul Metropolitan Unit as Narcotics. Narcotics deal with drug trafficking most of the time. There are two other pairs of partners in the same unit: Jangwook and Sooyeon, Hyunwoo and Hyejin. Your chief is Park Minsung, a male in his 40s. But the thing is: You, Heeseung, Hyunwoo and Hyejin are corrupted. Working for the police and mafia behind everyone's backs by merciless killing, stealing other mafia group's drugs and selling them to the middle man who hired you guys. Jangwook and Sooyeon don't have any idea that you four are corrupted as well as the chief of your department.

One day, a woman about the same age of all of you, entered the same unit as you guys. Her name was Kim Soonja. Heeseung hated her as she was always the touchy type and Heeseung had a feeling she was onto you guys about the corruption going on. All that dirty money you earned was enough to be nearly 137 billion won all up. Hyejin thought she was annoying but never said anything. Hyunwoo was also annoyed because of the same reason as Heeseung.

During a corrupted mission, the four of you was in the middle of slaughtering a mafia gang. As the four of you stepped out of the dim warehouse, blood-stained and victorious, Heeseung slung the duffel bag over his shoulder—the weight of the white pills inside heavier than it looked.

You barely had time to process the silence outside before a voice rang out.

"What are you doing here?"

It was sharp. Cold. Kim Soonja stood at the end of the alley, eyes locked onto the blood dripping from Hyejin’s sleeve.

The others froze.

"Tailing us, Soonja?" Hyunwoo said with a sneer, fingers tightening on his hidden weapon.

"You’re all dirty, aren’t you?" she said slowly, stepping forward. “I knew something was off. That missing evidence. Those unsolved cases. The timing of every single drug bust."

Heeseung cursed under his breath, already reaching for his gun. "I told you she was a problem."
