In her previous life, Su Jinye, the legitimate daughter of the Minister of Works, was gentle and virtuous. Yet her cousin and fiancé joined forces to frame her. Her family was destroyed, her loved ones died horribly, and her own life ended in the Cold Palace with a strip of white silk. When she opens her eyes again, she has returned to the eve of the turning point in her fate, at the age of sixteen.
This time, she sheds her innocence and conceals her claws. To turn the tide, she sets her sights on Xie Xuan, the Northern Pacifying Prince who holds power over the court: the cold-faced war god she once avoided at all costs, but who ultimately gathered her remains in her previous life. She carefully weaves a web of affection, drawing closer to him step by step until he becomes the sharpest blade in her hand.
At first, Xie Xuan thinks the young woman has a complicated look in her eyes, with her schemes written all over her face even as she pretends to be harmless. He watches her performance coldly, never realizing that he is getting caught up in it himself. When she finally achieves her goal and tries to leave, he catches her by the wrist, his voice low. “You used me and now you want to run? Nothing in this world comes that easily.”
From testing each other to standing side by side, from false affection to entrusting each other with their lives. When conspiracies surface again and enemies close in, they become each other's armor and weakness. Together, they fight their way through the whirlpool of power and true love, and find the light in each other.
