On a bloody moonlit night, an assassin breaks through the window. Consort Nangong, the Prince's consort, is severely injured and falls unconscious; when she opens her eyes again, she is in an unfamiliar world glittering with neon lights. Struggling to survive, she is shocked to find the people around her so familiar: her loyal maid has become her best friend, and her cold-faced arch-nemesis turns out to be her top boss. Until that unforgettable face appears, her prince is laughing and chatting with others, and when his gaze sweeps past her, only completely unfamiliar coldness remains. The fog of the pursuit has not dissipated, and a new battlefield has already begun.
