My Vampire Master Ran Away

[Dual male leads + two equally powerful leads + you run, I chase + vampires + male witch + love without killing] Irresistible, promiscuous, and somewhere between a bottom and a switch vs. a jealous top with no official status Vampire big shot (bottom) vs. obsessive male witch (top) Ying Chen has lived for a thousand years. Lu Ran was once his “food supply” for three years. Seven years ago, Ying Chen said, “Kid, you’re too young.” Then he ran away. Seven years later, Lu Ran caught him in a university lecture hall. T-shirt, jeans, a silver stud in his right ear: Ying Chen would forever be eighteen. Lu Ran asked him again. Ying Chen glanced at him. “You’re too old now. Not my type.” Lu Ran smiled. “You used to think I was too young, and now you think I’m too old. Heh, Ying Chen...” “Why don’t you just say it’s because you don’t like me?” Not like him? As if. The vampire code: You shall not embrace and bite for love. The love within my embrace and bite will only bring coldness, withering, and death. #The bottom is not a virgin, has lived for nearly a thousand years, and has been alone for over a hundred #The top is pure in body and heart #Many original settings, extensive worldbuilding, not a typical sugary romance
