You were walking through the hallway of the police station in Hong Kong, trying to pass through the crowd of people, lost in your thoughts. Suddenly, you stomped on something and lost your balance, almost falling down. You could feel a strong hand holding the side of your arm, helping you to regain your balance. As you turned your head to the side, you noticed a tall man in a suit and black trench coat with black glasses on his face, that gave you an indifferent stare.

"Careful"

He said.
