In order to cure mute disease, Su Zhenxue, a doctor with a poisonous tongue, kidnapped Qinxiu Shen Tinglan under the moonlight and imprisoned him in the Medicine Valley as a "human-shaped medicine guide". Next to the medicine stove on the cold bed, she held a needle to test the medicine, and her poisonous tongue was as sharp as a blade; he played the zither to express his thoughts, and the sound of the strings concealed the edge.
Shen Tinglan accidentally discovered the diary of her medicine boy. The lines were full of absurd jokes about "medicine should be used to induce Adam's apple and add a third of rhyme", but there was also a hidden concern about "the need to use mint to calm the nerves". During the three hundred and sixty-five days they were forced to live together, he saw the bruises left by her drug test, and she listened to the forbearance and tenderness in his music.
When an old feud reappears and the truth is revealed, Shen Tinglan realizes that behind her mutism is her determination to protect him. She also understands that this "drug inducement" has long since become an addiction. The fragrance of medicine is mixed with the scent of piano and ink, and the diary pages are full of offense, defense and emotion. From the cold words of "You are a good medicine" to the gentle words of "I will be yours for the rest of my life", they eventually become the voice in each other's throats and the antidote in their hearts.
The spring in the cage is deep, and the harp bones are fragrant with medicine. It turns out that the most powerful poison has been immersed in the most lingering love.
