Episode 1 recap: "The blue sparrow becomes the enemy's new concubine.
Yunhuan is a son-in-law of the royal mansion. One day, he received thirteen letters and couldn't help but wonder. He thought they were urging him to return to mourn, but it turned out that Mu Wang wanted to take a new concubine. Qingque is the leader of the Qinglou (brothel). This time, she offered herself to the Flower Pavilion because she received intelligence that the people who killed the Huai Prince back then were hiding in Mu Wang's mansion. Therefore, she wanted to marry into Mu Wang's mansion to sow discord between Yunhuan and Mu Wang. She planned to kill them both for her father's revenge when they were both injured.
When Yunhuan arrived at the Qinglou, he saw Qingque dancing gracefully with a veil covering her face. She intentionally flicked her water sleeves towards him. Yunhuan was curious about her true appearance beneath the veil. However, the veil could only be lifted by the one who took pictures of Qingque tonight. Mu Wang intervened and stopped him. Yunhuan couldn't insist and had to give up, but he found a pouch of Qingque's. In a moment alone with Qingque, Yunhuan asked her to explain why the pouch contained a deadly poison.
Qingque, feeling wronged, expressed her unwillingness to be forced into marriage with Mu Wang. She was trapped in the Qinglou and wanted to poison Mu Wang instead. Yunhuan looked into Qingque's eyes, which resembled someone he knew, and reached out to remove her veil. However, Qingque reminded him that whoever removes the veil would become her husband. Yunhuan immediately stopped and hinted that Mu Wang might not survive as the groom tonight.
Qingque appeared again, pouring wine for Mu Wang. Mu Wang believed that Qingque was his new concubine and lifted the veil. To his surprise, he saw Qingque's face beneath the veil. Yunhuan, seeing this, couldn't help but recall his deep affection for Qingque in the past, but he couldn't forget that she was the daughter of the Huai Prince, whom he had killed with his own hands."
Attention to those who find complicated relationships intriguing: In the past, the antagonist, Mu Wang, wiped out the entire family of the female lead during a conflict. In order to seek revenge, the male lead stayed by Mu Wang's side.
As the male lead's counterattack plan nears completion, the unexpected twist arises when the female lead appears with the intention of eliminating both of them.
