For Chiaki, a hostess at a "pink salon" (adult-oriented massage parlor), men were merely tools to be used; as long as she got paid and felt good, that was all that mattered. She assumed Aoyama, the civil servant she lived with, wouldn't meddle in her affairs—after all, he was a mama's boy. Little did she realize that Aoyama was beginning to see her as more than just a roommate... Then one day, Amagi, a divorced office worker, visited the shop. Chiaki found herself drawn to the cool, composed Amagi—a man who didn't immediately try to make a move on her body.
