Sent deep into the mountains for rigorous practice since childhood, Shen Chutang has mastered top metaphysics medicine, hacking technology, and superb martial arts. Her master observed the constellations at night, calculated that her romantic star was moving, and ordered her down the mountain to undergo her trial. At the entrance of the Civil Affairs Bureau, she bumped into Lu Beiqin, who was eagerly looking to get married due to his grandfather's critical illness. The two hit it off immediately, registered for a flash marriage, and set a three-month contract couple agreement. To test Shen Chutang's true intentions, Lu Beiqin deliberately disguised himself as an ordinary ride-hailing driver and started a cohabiting life.
