Lu Yanzhou and his wife, Song Qingya, insisted on splitting all expenses equally throughout their 36-year marriage. High-earning and domineering, Song Qingya meticulously calculated every expense but never showed any interest in her husband's work or personal life. After he retired, she asked him to become a full-time housekeeper, and Lu Yanzhou calmly proposed a divorce. Only after their separation did Song Qingya discover that her husband was a leading scientific researcher who had quietly amassed wealth for years because she had never cared enough to notice. As they resolved their past misunderstandings, Lu Yanzhou devoted himself to scientific research and family, finding warmth and peace. Song Qingya also let go of her domineering ways and returned to a simpler life. Their family learned to understand and support one another, living together in peace and reaching a warm, happy ending. The ending is heartwarming and promotes positive values.
