Toru had lived a loveless life, married off in a political arrangement to the daughter of his late wife's family. Starved for affection, his days grew increasingly chaotic, leading him to drown his sorrows in alcohol, trying to forget himself. One night, Yuna, his son's wife, came to check on him, expressing concern. Dazed from drinking, Toru found himself drawn to Yuna's beautiful, soft, glistening lips—and impulsively kissed her. It was a fleeting, instinctive moment, but the sensation lingered in his mind, haunting him late into the night. Later, he sneaked into Yuna's bedroom and kissed her again. Drawn to her warmth and sensual body, Toru began to awaken feelings he had never known before.
