Shen Qinghuan, a modern psychiatrist, traveled to Linjiang City under the fictional background of the Republic of China and became a penniless orphan. She discovered that her golden finger was the "emotional thread" that could see and touch other people's hearts - the embodiment of everyone's knots and obsessions. In order to survive, she transformed into an "interpreter", specializing in sorting out people's emotions and curing their heart ailments. When Lu Xiuyuan, the cold-faced and cold-hearted son of a warlord in the city, was backlashed by his inner demons due to an old case of massacre, and the black and red threads all over his body were as dense as a spider web, Shen Qinghuan broke into his world as a "medicine". This doctor-patient relationship involves the fateful entanglement between the two in their previous lives.
