Night Addiction Puzzle

Su Wan, a 22-year-old cutting-edge trace examiner, took over a series of "Dark Night Erosion Cases" after joining the Municipal Bureau's Criminal Investigation Detachment. He unexpectedly met the 29-year-old mysterious behind-the-scenes investor and temporary criminal investigation consultant Lu Chenyuan; he was a powerful man who walked on the border between black and white, and he was the one who saved her from deep trouble late at night many years ago. One murder case after another continues to uncover the dust of the past, and the two fall into each other's traps in dangerous investigations, pillow entanglements, and erotic games. While unraveling serial murders and years of conspiracies, they tear apart the layers of disguise, letting all the desires, hatred, and sincerity hidden in the night surface.
