Overnight, the whole family of the Zhenguo General's Mansion was wiped out, and the eldest daughter Shen Qingci fell from the clouds into the mire and became an imperial prisoner.
On the way to escape, she was accidentally rescued by Prince Jing Xiao Yu. This stern, ruthless and heavily armed prince made an absurd request - to let her be an obedient dog by his side.
In order to investigate the unjust case of his father's collaboration with the enemy and treason, Shen Qingci endured the humiliation and agreed to lurk in Prince Jing's Mansion under the name "Aci".
She dealt with various forces, and gradually developed a subtle relationship with Xiao Yu from mutual testing, but she did not know that there was a deeper conspiracy hidden behind this seeming protection.
Li Wenxuan, the son of the Prime Minister's Mansion, is pressing every step of the way, Zhao Kui, an old border officer, is behaving strangely, there are undercurrents at the Queen Mother's birthday banquet, and the blame for Su Wanrou's kidnapping...
Shen Qingci trudged forward on the road of revenge and survival. When the truth gradually emerged, she found that she had been trapped in a huge web of conspiracy. Is Xiao Yu her salvation, or the one who pushes her into deeper hell?
A battle between love and hate, loyalty and betrayal begins.
