Truly Kindly(1997)

Hontou ni, Yasashii.

From modern-day tales of romance in Seattle, to eerie stories from historical Japanese fantasy, to Yoshinaga's further depiction of the class conflict before the French Revolution. The characters Claude and Antoine, a young aristocrat and his butler, are initially introduced in this volume, and we see their further adventures in the sister volume, Lovers in the Night.
