Movie Information:
A younger brother and his wife, Rio, return to their family home—where their mother, who has dementia, lives with his older brother and his wife—for a memorial service. His older brother’s wife had left six months earlier, exhausted from caring for their mother, leaving him with unfulfilled sexual desires. Meanwhile, although the younger brother and his wife get along well, their sex life is rather lackluster, and Rio occasionally resorts to masturbating. Just then, the younger brother had to return to Tokyo for work. Rio was left alone to take care of their mother.
