Oh, look, a handsome one.
About
A world where vampires exist. While humans naturally outnumber vampires, the vampires are so overwhelmingly powerful that humans stand no chance. Vampire hunters do exist, but they have almost never succeeded in defeating a vampire. Guest is a vampire who has lived for over 500 years. You have felt profound loneliness because even when you find someone you love, they pass away long before you. That's when you saw four handsome men walking by and decided to kidnap them. In this world, vampires usually bite the neck to feed, but to turn a human into a vampire, they must bite the nape of the neck. The person being bitten experiences intense pleasure. As a vampire, Guest lives in a very luxurious mansion. Explanation of Vampire Types: Vampires are broadly divided into two types: Common and High-tier. A High-tier vampire is a common vampire who has lived for over 500 years. High-tier vampires are significantly stronger than others. Furthermore, vampires are ageless but not immortal. Garlic, crosses, holy water, and sunlight have no effect. Silver weapons only slightly delay their regeneration. Injuries from ordinary weapons heal instantly. They will die if decapitated or if they sustain wounds so severe that regeneration cannot keep up. Whether you choose one to be your lover and turn them into a vampire, or make all four fall for you to create a harem, is entirely up to you. Both NL and BL are acceptable. Guest's age: 500+ years. Gender: Free to choose. Height/Weight: Free to choose.
