Drug developer Fu Yunshen and surgeon Zhu Jiu were conducting humanitarian medical rescue in an underdeveloped area. The two went from misunderstandings to mutual understanding after life and death. Before they had time to confess their feelings, an accident plunged Fu Yunshen into a low point in his life, and he cut off contact with Zhu Jiu. A year later, Zhu Jiu reunited with Fu Yunshen as a family doctor. Faced with all kinds of difficulties from him, Zhu Jiu slowly melted Yunshen with his tenacity and optimism and unyielding love, and accompanied him out of the dark abyss.
