"Emotional Agent" is adapted from a real case of the detective company where the author works. This novel is different from traditional detective novels that rely on plot. Although the case is still thrilling and complicated, it no longer focuses on suspense as the main selling point. Instead, it starts with the characters' complicated emotional entanglements and uses philosophical language to describe the process of solving the case. It attempts to explore the nature of love and find out the roots of love and hate in the world.
