Kami-sama no Memochou - Volume 5, The Detective and the Love Professor

Yu Li and her boyfriend had known each other for four years and had been together for three. They were deeply in love.Her boyfriend was gentle and considerate. Apart from being a little too clingy, lacking a sense of security, and always dragging her to watch horror movies, he had no other flaws. They were about to get married when a car accident took both their lives.After death, she transmigrated into a book.The good news? Her boyfriend transmigrated too.The bad news? He lost his memory.The even worse news? Some entity calling itself a “system” told her that her boyfriend was originally the villain of this world.And not just any villain—he was a twisted, obsessive, and deeply dark antagonist, completely fixated on the female lead.This world operated on eerie, supernatural rules. The protagonists would be pulled into horror movie scenarios at night to complete survival missions. If their performance scores were too low, their lives would be at risk.And her little boyfriend was already teetering on the edge of danger.Yu Li fell silent.Amnesia, transmigration, and an infinite flow survival game.Now that’s what you call stacking buffs.—The first time she entered a horror scenario, she became the neighbor of the protagonist group. When the male and female leads came over for a visit, her gaze landed on the second-floor window of the house across the street, and she silently curled her lips into a smile.That night, a mu*derous ghost who had claimed countless lives turned into a wisp of smoke and slipped into her home, lying gently beside her. Lowering its head, it inhaled her scent like an addict, utterly intoxicated.“You smell so good… I want to eat you up… So good…”
