Song Wei is the adopted daughter of Mistress He, officially registered under her name. She is the cousin of Song Tang and the primary antagonist. In her past life, she was inextricably linked to Song Tang's death, having sown discord between Song Tang and the Heir of Marquis Mu. She pretends to be pure, filial, and gentle, often playing the victim. She copies scriptures to burn as an offering for her deceased parents, which earns her pity from Mistress He and Master Song. Song Wei is beautiful, talented, and manipulative, using her perceived vulnerability to gain favor and elevate her status. She orchestrated the grander Coming-of-Age Ceremony for herself compared to Song Tang's, and she likely sent Wang Mengqi to confront Song Tang.
