During the Song family's monthly family dinner, the patriarch Song Yuanhong publicly announced that his illegitimate daughter Song Qingwan would be betrothed to the Lu family's only son Lu Siting in exchange for the Lu family's legal support for the land in the south of the city. Qingwan's biological mother died young and had no status in the family. Her stepmother and sister Song Qingyao ridiculed her. Qingwan lowered his head and said nothing, but the flame of resistance ignited in his heart. After the banquet, she returned to the attic room alone and took out her lawyer's license and an old notebook on hypnotism from the secret compartment - those were the relics left to her by her mother. She decided not to hold back anymore.
