In her previous life, she was dazzled by the wealth in the house and willingly became the mistress' pawn. The courtyard deeply ground her self-righteous ignorance. Her broken innocence experienced the viciousness of despair in the wind and frost swords, but she could not escape the man's callousness and ruthlessness. When her young life was dissipated under the stick, that sigh may have made her regret her past recklessness and rashness.
In the new life, this life no longer blindly follows the family's desire for wealth, no longer believes in the mistress's promises, and no longer fantasizes about men's sweet words. Perhaps she is still a humble slave, at least better than the misery of her previous life.
