After the palace maid A Jin accidentally fell into the water, she gained the ability to hear other people's thoughts. Living in the royal court, she initially thought that the officials would be full of schemes and state affairs, but she unexpectedly found that these seemingly stern and cold high-ranking figures were actually soft-hearted and love-struck fools in private.
The cold-faced general secretly loves a gentle young lady but is too insecure to confess; the aloof prime minister is obsessed with the princess, struggling awkwardly on the path to pursue her; the distant emperor cares for the icy consort and suffers from longing just to save face; the war god King Rui is infatuated with a rigid female scholar, and their mutual feelings are constantly misunderstood.
Seeing through everyone's hidden thoughts, A Jin becomes a secret matchmaker in the palace, quietly helping to untangle all their romantic dilemmas. Using her mind-reading ability, she also uncovers palace conspiracies and prevents political coups, ensuring the emperor and the realm remain safe. After witnessing all the palace intrigues and human love stories, A Jin decides to resign and leave the palace, opens a teahouse, and enjoys watching everyone's lives flourish while living her own life in peace.
