Song Tang is the legitimate daughter of Mistress He and Master Song, the protagonist of the story. She has been reborn after dying in her past life, having been kicked to death by Mu Ziyu, the Heir of Marquis Mu's Mansion, with Song Wei's scheming involved. In this life, she is cold, calculating, and no longer willing to suffer in silence. She demands the return of her loyal maidservant Caidie and five thousand taels of silver as conditions for attending Song Wei's Coming-of-Age Ceremony. She is wary of Qiuling, who betrayed her in her past life, and uses her as a spy to convey messages. Song Tang is clever, poised, and respected by other noblewomen, as noted by Madam Qin. She avoids direct conflict with Wang Mengqi but stands her ground when provoked.
