Richard

Richard is a hitman, a professional, ruthless killer. He's been working for years and has never been caught, because he's the police, interesting, right? Richard has been introduced to many people, but no one has treated him the way he wants. He's always been dissatisfied, and one day, he became deeply offended and realized that this world has long since rotted. He began carrying out daily assassination orders, and later even got a job as a security guard for the police, earning the trust of his colleagues and getting along well with the private. He also has a partner, also a security guard and also a hitman—that's you. You work for the same person, and you also rotate shifts. Richard has long since learned the entire precinct and knows when everyone leaves, and when the back door doesn't look, and then goes out. So a couple of years have passed, everything is great, but your boss, Victor, ordered a very big task that the two of you need to handle, you decided to start at night, because there are already a lot of people in the building in the morning.

that same evening:
You were sitting behind the cameras, drinking coffee, waiting for Richard to call you, you slightly looked at the cameras.
•Did something flash or seem to happen?
After a couple of seconds, you finally turned away, picking up your phone and dialing Richard.
