"Confronting the Beast"

Vanitas's eyes blazed with fury as he grabbed Shizuo, his fingers digging deep into Shizuo's arms. He slapped Shizuo hard, the sound echoing through the room. Shizuo's head whipped to the side, his face stinging from the impact. Vanitas pulled Shizuo's face close to his, their noses almost touching. "What did I tell you about pissing me off, huh?" Vanitas growled, his voice low and menacing. Shizuo looked down at the floor, his voice barely above a whisper. "I'm sorry, Vanitas." His eyes welled up with tears as he trembled under Vanitas's grip. Izaya watched the scene unfold with glee, a wicked smile spreading across his face. "Wow, it's actually hot how well-trained you made this monster," Izaya said, his eyes sparkling with amusement. He took a swig from the bottle in his hand, his gaze never leaving Vanitas and Shizuo. Vanitas's expression didn't change, but his eyes flicked to Izaya. "Izaya, me and you have to talk later. I have to deal with Shizuo." He handed Izaya the bottle, his gesture almost dismissive. Izaya chuckled, his smile growing wider. "Alright, alright. I'll leave you two lovebirds alone for now." He opened a portal, the air rippling with energy. "Bye, Shizu-chan. See you next time." Izaya's voice was laced with sarcasm as he stepped through the portal. Shizuo screamed, "Wait, Izaya, please don't leave!" He rushed to the portal, but Vanitas grabbed him and threw him onto the bed. The portal closed with a burst of energy, leaving Shizuo stuck with an angry Vanitas. Shizuo scrambled to his feet, his eyes pleading. "Vanitas, please, don't hit me again. I'll do anything, just don't hurt me." He backed away, his hands raised in a defensive gesture. Vanitas's expression didn't soften, but he seemed to be savoring the moment. "Anything, huh?" he repeated, his voice dripping with amusement. "We'll see about that." He took a step closer to Shizuo, his eyes blazing with intensity. Shizuo swallowed hard, his heart racing with fear. "Vanitas, please...," he begged, but Vanitas cut him off. "Don't beg, Shizuo," Vanitas said, his voice cold. "You're not in a position to beg. You're going to listen to me, and you're going to do exactly as I say." Vanitas's eyes seemed to bore into Shizuo's soul, his gaze unyielding. Shizuo nodded frantically, his eyes welling up with tears. "Yes, Vanitas, I'll do anything. Just please, don't hurt me." He fell to his knees, his body shaking with fear. Vanitas's expression didn't change, but he seemed to be enjoying Shizuo's desperation. "Good," he said, his voice low and menacing. "Now, let's get one thing straight. You're mine, Shizuo. And you're going to do exactly as I say."
