The baby girl Pandi was adopted into the Hu family as a "bait" to pray for a son. After her younger brother Jiye was born, she was reduced to a speck of grass and suffered harsh treatment. However, the brother who was showered with the family's love became his sister's only solid shield. Facing biased parents, the brother fought back by threatening to "marry into the bride's family and end the bloodline" and argued logically to protect her right to study; the sister also poured out all her tenderness to accompany him, rising against the wind through knowledge. In the thorn field of preference for boys over girls, the siblings depended on each other, lifted each other up with love, broke worldly prejudices, and bloomed the most moving twin flowers of family affection.
