In a quiet residential neighborhood stands a 40-year-old traditional Japanese bungalow. Though the house hardly looks affluent, it boasts a spacious backyard and an open veranda. Seated on the veranda is the sorrowful big-breasted mother, Ijuin Akane. With a gloomy expression, she sighs deeply. She holds a broom and dustpan, seemingly preparing to clean the garden, yet remains seated, sighing in distress. The reason lies behind her—her son, Minoru. Without a word, he silently gropes his mother's large breasts, burying his face against her nape, breathing heavily as he comforts her. Within the quiet home and the stillness of everyday life, a complex mother-and-son relationship unfolds.
