**Chapter 1: The Vampire's Proposal**

Izaya Orihara stood before the rundown apartment, a mixture of nostalgia and disdain washing over him. He hadn't been back to this part of town in years, not since his...transformation. The streets were just as dirty, the buildings just as worn down, but Izaya was no longer the same man he used to be. He was now a creature of the night, a vampire driven by his baser instincts. And one of those instincts was telling him to claim Shizuo Heiwajima as his own. He knocked on the door, and after a moment, it creaked open to reveal Shizuo's disheveled appearance. The man's eyes narrowed as he took in Izaya's sleek, modern attire. "Orihara...what do you want?" Shizuo growled, his hand resting on the doorframe as if ready to slam it shut at a moment's notice. Izaya smiled, his fangs aching to descend. "Shizu-chan, I'm done fighting you now. You coming to live with me now and become my wife," he said, his voice low and menacing as he grabbed Shizuo's chin and pulled him closer. Shizuo tried to push Izaya away, but the vampire's grip was like a vice. "Move, damn flea," Shizuo snarled, his eyes flashing with anger. Izaya's eyes turned red, and his fangs descended, glinting in the dim light of the hallway. "Your mine, Shizu-chan," he whispered, his breath hot against Shizuo's skin. Shizuo struggled, but Izaya's hold was too strong. He was pinned against the doorframe, Izaya's face inches from his own. "Let me go, Izaya...you're not normal anymore," Shizuo said, his voice laced with fear. Izaya chuckled, a low, husky sound. "Normal? Ha! I've never been more alive, Shizu-chan. And I want you to be with me, to experience this...new life." He leaned in closer, his fangs brushing against Shizuo's skin. "Imagine it, Shizu-chan. We can walk the streets at night, free from the constraints of the sun. We can be together, always." Shizuo's eyes widened in horror. "You...you're a vampire now. What makes you think I'd want to be with you?" Izaya's grip on Shizuo's chin tightened. "Because, Shizu-chan, I've always had a certain...fondness for you. And now, I can make you mine, truly mine." He pulled Shizuo closer, his lips brushing against the man's ear. "You'll love me, Shizu-chan. You'll love me, and you'll be mine, forever." Shizuo's face twisted in a snarl. "Never. I'll never be with you, Izaya." Izaya's smile grew wider. "We'll see about that, Shizu-chan. We'll see about that." With a sudden movement, he swept Shizuo off his feet and into his arms, carrying him into the apartment as if he weighed nothing. As they crossed the threshold, Shizuo's struggles grew more frantic. "Let me go! I won't go anywhere with you, Izaya!" Izaya simply laughed, his eyes gleaming with excitement. "Oh, Shizu-chan...you have no idea what's in store for you." He kicked the door shut behind them, plunging them into the darkness of the apartment. And in that darkness, Izaya's true nature waited, patiently, to claim Shizuo as his own.
