Ling Qingyue travels to the capital to find her father, never expecting that her real father is Xiao Chen, the regent, who has been poisoned by a parasite and is on the brink of death.
After saving her father, she discovers that the promiscuous princess has her eye on him.
Even more absurdly, the princess sends her adopted son, Chu Zheng, to seduce Ling Qingyue. She turns the tables and flirts right back, having the time of her life.
The regent and his wife stand up for Ling Qingyue and have her back. They have never treated her poorly just because she was born outside their marriage.
So she fears nothing and charges headlong into helping her regent father investigate who poisoned him.
But as the truth is gradually revealed, she discovers that everyone at the chessboard has their own agenda and wants to win, yet no one knows they are all just pieces...
