A thunderous laugh broke through the quiet of the ninth floor, followed by three light, delighted female giggles. Although many people had gone to the building's cafeteria or to the adjacent streets to eat, the employees who had stayed at their posts or taken over the break room for lunch were still present in large enough numbers to generate a soft sound of voices and cutlery hitting the plastic of their containers and bento boxes.
The men and women present were talking about their clients, their families, or their hobbies, when they weren't just eating in silence, their eyes riveted on their cell phone screens. They were so focused on their TV series, webtoons, or video games that nothing could have pulled them out of their concentration. Not even the big laugh that resounded again.
They were probably used to hearing these hilarious eruptions from Chief Tsukasa; his big voice had melted with the sound environment to become an inseparable part of it.
