Modern psychotherapist Jiang Xinyue accidentally traveled through time and became a nobleman who had just fallen out of favor in Dayan's harem. She was on the edge of the cold palace, but she had a pair of good cards - her alluring appearance and her professional ability to understand people's hearts. On the surface, she is weak, infatuated, innocent and harmless, but secretly she treats the palace as her workplace and the emperor as her boss, and uses her emotional value and precision to manipulate the emperor's heart. From a chance encounter falling into the water in the imperial garden to winning people's hearts at a barbecue banquet, she climbed from noble to precious concubine step by step. However, the harem is never a battlefield where one fights alone. The queen's calculations, the concubine's arrogance, the queen mother's coercion, and the concubine Shu's old love. Everyone is playing a game of chess. And she is the one who seriously wants to win.
