About Obsession
One character's fixation on another consumes the narrative — watching, collecting, orbiting — whether it resolves into requited intensity or curdles into something dangerous. Tagged clearly so readers can choose how dark they want the spiral to go.
Obsession dramatizes the terrifying edge of wanting, and readers are drawn to fiction that admits desire is not always tidy or safe.
Common scenarios: A profiler realizing the elegant murders are love letters addressed to him, or a rival who has memorized every match, interview, and weakness of the person they claim to hate.
