Shen Qingci, an orphan from the Shen family who was burdened with a blood feud, used marriage as a bait to marry into the regent's palace and formed a seemingly cold alliance with Xiao Jue, who was powerful but unpredictable. She holds the Dark Night Merchant Alliance in her hands, and is working every step just for revenge; he is sitting on a huge power, strategizing in the undercurrent of the court, but he is sincerely moved by this sharp-edged "chess piece".
From using each other to test each other, to trusting to fight side by side, they were tossed between conspiracies and blades: the third prince's frame-up, Su Mingzhe's viciousness, Liu Ruyan's deceitfulness, pushed the two to desperate situations time and time again. Xiao Jue struggled between anger and reason, and finally used the secret protection of "hard-spoken and soft-hearted" to protect her from the fatal storm; Shen Qingci wandered between hatred and temptation, but at the moment he sacrificed his life to protect her, he dropped all his defenses.
When sudden changes occurred in the palace, he led troops to quell the rebellion, and she stabilized the capital. The tacit understanding of internal and external cooperation has long transcended the boundaries of "allies". On the day when the Shen family's injustice was revealed, he publicly declared, "I will take over her past, and I will protect her future." He used power as a shield to protect her.
After the revenge was over, the Dark Night Merchant Alliance turned into the "Benefiting the People Merchant Alliance" and became the people's help in governing the world; and during their semi-reclusive years, they integrated their strategy and affection into their daily necessities. From the suspicion of the cold courtyard of the palace, to the tenderness of fellow travelers in the south of the Yangtze River, from the dependence of life and death on the blade, to the deep affection between the beds, this relationship that began with calculations eventually became the hottest embers in each other's lives, illuminating the rest of their lives.
