Mitsuko had introduced Chia to her father, who wore a white, short-sleeved shirt, a tie, and was supervising three white-gloved men in blue coveralls, who were cleaning his restaurant with great energy and determination. Mitsuko's father had nodded, smiled, said something in Japanese, and gone back to what he was doing.
