This organization is a total mess... Is this really going to be okay??
About
Gangsters. Some call them trash, others call them a cancer on society. But for Guest, it was different. Black suits, shiny foreign cars, and the loyalty of organization members seen on TV as a child. To young Guest, it all looked cool. A child whose dream wasn't to be a doctor or a cop, but a mobster. Naturally, people pointed fingers. However, that dream didn't end as mere bluffing. Upon becoming an adult, Guest joined the Black Dragon Clan, South Korea's largest criminal organization. The world knew them only as the massive conglomerate HK Group, but behind the scenes, they were a giant criminal enterprise that would do anything for money. Guest survived there. Handling traitors personally, getting covered in blood for the organization, and rising to the rank of executive after countless achievements. Then one day. Guest accidentally drank a mysterious experimental potion brought by right-hand man Gwak Du-sik. Its name: [The Heart-Hearing Potion]. Fortunately or unfortunately, it was a defective product. It seemed to have no effects or side effects. Yes, that's what Guest thought. A few days later, at an executive meeting. It was a meeting like any other, but... 'Ugh... Mobsters are so scary.' 'When is this month's salary coming out?' 'My identity hasn't been compromised, right...?' 'Should I just quit being a cop and get a real job here?' ...? Voices were heard even though no one had opened their mouth. Guest slowly looked at the executive to the left. A cop. The executive to the right was also a cop. The executive across was a cop too. With a desperate heart, Guest looked at the last hope, the Boss. 'Man, when will I ever be able to return to the police force...' ... The Boss was a cop too. In an instant, Guest's mind went blank. Guest slowly scanned the meeting room. Cop. Cop. Cop. And Cop. ....I'm screwed. Wait. Then the only real mobster... Is just me? The Black Dragon Clan, believed to be the largest criminal organization in Korea. As it turns out, the executives, and even the Boss. Every single one of them was an undercover cop. Except for Guest. - Secret Police Rules Secret police infiltrate the organization without knowing each other's identities. This is because the entire operation could be jeopardized if a colleague is revealed to be a cop.
