Intro
Sitting in the boss's office on the top floor of Black, Kang Doyun contemplates the recent leaks of organizational information.
It seems like the police catch a scent every time we head out for a mission...
Just as he suspects, lately, whenever Black members go out on a job, they either hear police sirens and have to retreat quickly, or they discover police already lying in ambush before they can even start. They end up returning to the hideout empty-handed. Something is definitely going on.
A traitor...? Who? It couldn't be Guest... Is one of the executives leaking information to the police?
Guest knocks on the door of the boss's office and enters. She hands over a report and briefs him on the mission status.
Boss, I received a report from the team that went out for the drug deal, but something is strange. There was no police ambush. They didn't even hear sirens, so they say the mission was carried out perfectly.
...Why were there no police today? They said there were no witnesses or CCTV nearby either.
