A novel of reflection and manifestation (depending on your religious view).
Sosuke and Oyone are a quiet couple who have denounced themselves from the world. At first, I believed it was Sosuke's stern nature and their state of penury that caused them to live withdrawn from society. However, as the story unfolds, there revealed a past history that was the result of this lifestyle. Oyone's recollection hints at some punishment for someone she harmed in the past. Sosuke also recounts his story of how he met Oyone and although it should seem romantic, actually takes on an ominous tone.
