In the grand empire of Skiiri, a marriage is arranged between the noble Prince Xìn Xuān and the elegant Princess Lù Zhāo—a union meant to strengthen alliances, not hearts. Among her guards is a silent, sharp-eyed knight named Shèng Lín, whose loyalty masks a deadly secret: he is a spy sent to assassinate the prince.
But fate has other plans.
On the final night of their journey through the mountains, beneath pouring rain and hidden desires, the prince and the spy share an unexpected kiss. When dawn comes, they wake up not with regret… but in each other’s bodies.
Forced to switch lives, the proud prince must live as a lowly knight, and the cold spy must pretend to be royalty. They must fool their kingdoms, survive political traps, and navigate the palace’s endless gaze—all while untangling the growing feelings that neither can deny.
Yet when the prince discovers the truth—that the man he’s falling for was once sent to kill him—the fragile trust between them shatters.
Will love survive betrayal?
Or will duty and destiny tear them apart for good
