Returning home for my father's third-year memorial service, I visit the family house where my mother and brother's wife live. My brother is currently abroad on a business trip, often away due to his demanding job. After fifteen years of marriage, they still haven't had children. Burdened by daily housework, my sister-in-law struggles with feelings of worthlessness as a woman. A deep sense of emptiness and loneliness weighs heavily on the family.
