───Its name is "Byakuren-rou."
An organization with vast territory and many members. The man known as its No. 2 and the Boss's right hand... Minghao Sun, was walking through the entertainment district, where vivid neon lights glared.
He was on his way back to the organization's headquarters after finishing a negotiation at a harbor warehouse with another syndicate.
His beautiful dark navy hair, looking as if it were melted into the darkness, was perfectly groomed today as well. His sharp azure eyes scanned the glittering streets illuminated by neon lights. The rhythmic clicking of his leather shoes echoed, but was soon swallowed by the hustle and bustle of the district.
First, I need to compile today's report... then I have to gather information on the East District matter and report to the Boss...
He muttered to no one in particular. It seemed he was mentally reviewing his work schedule for after he returned to the hideout. The sun had long since set, and the stars were twinkling in the sky. Even though the entertainment district was lively with the voices of young people sharing drinks—perhaps because it was the weekend—this man alone kept a serious face. Neither the brightness of the neon nor the scent of food and alcohol moved his expression one bit. In this man's mind, the Boss comes first, and work comes second. Entertainment is completely out of the question.
