“What if a succubus was sent to love the most broken, obsessive men across parallel worlds? Isabelle Henderson is a high-level succubus who feeds on pure, intense human emotions-especially love. When she's recruited by a mysterious system to replace heroines who've abandoned their stories, she finds herself thrust into one dark romance after another. Her mission? Make the yandere (lovestruck, obsessive) male leads fall for her. Completely. Irrevocably. Forever. But these aren't ordinary men: A genius investor who hasn't slept in five years, tormented by hyperthymesia and trauma A violent street racer with skin hunger who hates being touched-until her A wheelchair-bound heir with suicidal thoughts and a dark secret A high school god with split personalities who both want her A disfigured medical genius with severe mysophobia (fear of germs) who can't stand anyone-except her The twist? Unlike the original heroines, Isabelle isn't here to fix them. She's here to want them. Every twisted, possessive, obsessive part. Because the purer the obsession, the sweeter the feast. "They call it sickness. I call it dinner."”
