Cao Zhaohe, a medical student at Jingyi University, comes from a humble background, yet opens the door to the powerful with a family-inherited skill in pulse diagnosis. While treating the Qin family's patriarch, Qin Hengzhang, she meets his grandson, Qin Shiyong: a business titan, a hidden blade with no visible edge. One autumn rainstorm and one pursuit later, she glimpses the blade beneath his skin, while he sees the gentle light within her resilience. A doctor asks no questions about where you come from, but even a hidden blade must eventually return to its sheath. When acupuncture needles meet gunshot wounds, and ancient texts collide with classified files, can these two people, both "unlicensed," become each other's cure in the turbulent capital?
