Shen Jingyuan was the eldest daughter of the Zhenguo Palace of the Dajing Dynasty. In her previous life, she mistakenly believed in a scumbag man's concubine. She had her heart ripped out and her whole family died tragically. Even the secret guard who had grown up with her and was loyal to her, thanked her, but was hacked to death with knives to protect her, leaving no trace of her body. Once she was reborn, she returned to the age of fifteen and the eve of her haircut ceremony. All that was left in her eyes was coldness and ruthlessness, her former gentleness faded away, and she transformed into a cool and sassy daughter-in-law. She was dedicated to revenge, abuse, and protection of the family. She no longer talked about the love between her children. Xie Ci is Shen Jingyuan's personal bodyguard. He was adopted by the Duke's government since he was a child. His destiny is Shen Jingyuan. He is taciturn, extremely skilled, and a paranoid loyal dog. In his previous life, he loved her deeply but dared not express it openly. He could only guard her silently as a bodyguard, and finally died for her. After rebirth, Shen Jingyuan no longer turned a blind eye to him, but still maintained the cold, arrogant and distant attitude of his legitimate daughter, and only regarded him as the most capable subordinate; but Xie Ci took advantage of the opportunity of rebirth (with the obsession and memory of dying in her previous life) to completely transform into a clinging and loyal dog, guarding her at all times, with only her in his eyes.
