Su Qingyi has been married into the Li family for two years and is regarded by everyone as an uneducated housewife. Her entire family showers all their resources and affection on her husband's childhood sweetheart, Shen Yaqin. But nobody knows that Su Qingyi is a scientific research genius. She writes formulas on her apron and hides manuscripts in the rice jar, quietly overcoming a bottleneck in a crucial algorithm. On the day she is supposed to register at university, Shen Yaqin publicly accuses her of writing love letters to seduce another man and burns her letter from the research institute. The whole family demands that she admit her wrongdoing. Finally pushed beyond endurance, Su Qingyi overturns the dining table, signs the divorce papers, and cuts all ties with the Li family.
