Kill Them Off, One by One

Minhyun sat at his desk. His eyes were staring at the screen in front of him, taking in the CCTV video that was retrieved by White Mask. While Yoona was away on dinner with her friends, he had decided to stay in his office.

And he was glad he did. Before him was a jewel of a video.

The contents were supposed to be erased - key word 'supposed' - but before it could be removed, White Mask was able to store it inside its database. The AI was able to track down where Minhyun's enemies were and capture control of all the CCTV cameras. It was as if he had eyes everywhere - and he did.

A dark alley, right behind a bar, barely able to capture anything. It was placed there for legality but the owners were able to pay their way out so that it won't be able to capture any of their underhanded deeds. But once in a while, there was a gem that would appear. The men who brought the girls into the alleyway, too drunk to realize that they were being filmed.
