: Cui Buyan has a secret: he can smell lies. The sour one means guilty conscience; the smelly one means malice; the fishy one means the smell of killing someone. Relying on this ability, he became the youngest negotiator in the business circle. Until he attended his fiancée's family dinner, his father-in-law-to-be smiled at him with a wine glass: "Xiao Cui, we will be a family from now on." Cui Buyan's stomach churns - he smells a strong smell of blood, which is fresh. That night, he stood at the door of the basement of his fiancée's house, his hands shaking so much that he could hardly turn the doorknob.
