Jiang Xinbai (played by Luo Yunxi), the cold and arrogant county king and chief catcher who suffers from prosopagnosia and vows to wipe out Wuxiang% in the world, accidentally meets the eccentric and changeable person every month when he secretly investigates the Wuxiang case.Yan Nanxing (played by Song Yi), a hot-blooded traveling doctor in the world, has never been acquainted with each other. For the secrets hidden in each of them, they experienced a wonderful marriage together, and finally worked together to eliminate the evil of Wuxiang.It also allows the audience to appreciate the true meaning of love through the process of two strong and lonely people, Jiang Xinbai and Yan Nanxing, working together to protect justice. Although face is important, it is not worth the connection of heart and mind. Love is not possession.It is not robbery. The so-called "obsessed with love" does not only focus on external characteristics. Real love is to abandon external factors such as appearance, class, hatred, etc., to persist in the pursuit of justice, and to be willing to take a lifetime responsibility for this love, and even protect it.The responsibility of everyone in the world.
