The brocade tent overturned, and the flames gnawed at the bones. Shen Qingci, the legitimate daughter of the Marquis of Yongning, mistakenly believed in the "deep sisterly love" of her concubine Shen Qingrou in her previous life, and was obsessed with her fiancé Gu Zhaoyan's "sworn oaths of friendship". She ended up being imprisoned in a woodshed and burned to death - her wet nurse died tragically, her mother was poisoned, and her dowry was swallowed up. Even her father turned a blind eye to her desperate situation for the sake of the Marquis's reputation and career.
From the step-by-step preparation in the palace, to the undercurrents of the chess game in the court; from the determination to seek revenge alone, to the mutual sympathy with Prince Jing - Shen Qingci is no longer the gentle daughter-in-law who can be manipulated by others, but a man in power with intelligence as his blade and tenacity as his armor. Not only does she want to repay the blood debt of her previous life, but she also wants to rewrite the fate of her family, protect all the people she cherishes, and carve out her own beautiful path in the treacherous deep house and court.
