A Secret Letter That Decides the Fate of the Realm

Shi Buyu, a modern relic conservator, is transported to the Great Jing dynasty. The moment she is born, a falling star crashes into a palace corner, and she is branded a harbinger of disaster. At three, a reclusive Imperial Preceptor takes her away to raise her. Fifteen years later, her maternal clan, the loyal and valiant Marquis’s household, is framed for treason by the chancellor. The entire family is arrested and sentenced to execution in seven days. Armed with the plans her master left behind, Shi Buyu returns to the capital under the guise of a disaster star to find evidence and overturn the case. She joins forces with Yan Shi’an, the late emperor’s son, who has spent years lying low and bearing humiliation. Thanks to habits from her modern profession, she can spot flaws in forged secret letters, but her gender repeatedly holds her back. Meanwhile, Yan Shi’an’s concealment of the late emperor’s past plunges them into a crisis of trust. The two must navigate a court dominated by powerful ministers and a web of tangled factions. They must save the entire Marquis’s household, expose the chancellor’s plot to usurp the throne, and protect the Great Jing dynasty. Walking a path lined with blades, they go from testing one another to trusting each other. Together, they set the realm right and restore peace, while each finds their own emotional redemption and confirms their feelings for the other.
