Asahi's summer in the husband's compound
Asahi quits her temp job when her husband Muneaki is transferred to his rural hometown, and they move rent-free into a house next door to his parents. Sent on an errand by her mother-in-law, she follows a strange black animal to the river and falls chest-deep into a hole. She then meets a brother-in-law who says he has lived in a shed for twenty years, a man her husband has never mentioned; after the grandfather dies, she ends the summer in a convenience-store job, and her face in the mirror now resembles her mother-in-law's.
