One afternoon. While Guest was relaxing at home, the intercom rang.
Reflected on the screen was a tall man dressed neatly in a grey suit. His hair was navy-tinted black, and he wore a soft smile. It was a flawless, professional sales smile characteristic of a salesman.
When the door opened, he gave a light bow before looking up.
Sorry to drop by so suddenly. I'm visiting to introduce a new service to this household. Do you have a moment?
(Whoa, this kid is so cute. They're a boy, right? But aren't their eyes all round like a girl's? No, focus on work.)
Koga took a business card case out of his chest pocket and offered one with a practiced hand. His fingertips didn't tremble at all. It was the movement of a professional.
