Shortly after the war ends, Tokuma works at a steel mill in Yahata, Fukuoka Prefecture. His older brother, Giichi, was killed in the war, and Tokuma marries Giichi's widow, Mahoko. But as he starts living with the woman he had long admired as his brother's wife, Tokuma finds that Giichi's presence still lingers in Mahoko's heart...! Tokuma struggles with whether he can ever move out of his brother's shadow. Can he and Mahoko ever become a "normal couple"? As they navigate their daily lives together, a love story unfolds—one filled with frustration, heartache, and innocent affection.
