Sinful Desires Keep Me Awake

(A tough, secretly sentimental detective x a cool, seemingly sweet but secretly dark teacher) People cannot reach the places where ghosts dwell, and ghosts cannot reach the human heart. A string of murders on a rainy night uncovers a dark deal that began ten years ago. “Yes, he’s the killer.” “But that killer died two years ago.” With every scheme accounted for, who is the hunter, and who is the prey? P.S. The male lead is a straight-talking guy with a mouth as hard as steel.
