A housewife without children spends her days buried in household chores, quickly passing each day with reading or knitting, leaving her emotionally drained. Her husband returns home late every night, too exhausted to pay attention to her, and falls asleep immediately. Since marriage, she's grown increasingly lonely, sensing emotional distance from him. Unable to burden her tired husband with her feelings, she keeps telling herself she must endure. But eventually, her heart reaches its limit. She leaves home and embarks on a journey with a man she just met. At night, thinking of her husband, she feels a deep ache in her heart.
