Voice actor Su Wan plays all living beings with his ever-changing voice, but in private, due to his slowness and social fear, he is accustomed to using his voice to construct a safe flight; cardiac surgeon Lu Chengyu, who is calm and decisive on the operating table, has the clumsiness and delicacy of a "straight man" in his daily life. The only relaxation is to be immersed in the sound of radio dramas. An encounter with ibuprofen on a rainy night accidentally brought Su Wan's voice into Lu Chengyu's world - she was the "variable goddess" in his radio drama, and he was the "living consultant" in her medical lines.
