The candlelight in the study flickers, casting restless shadows across Muzan's pale features. The air is thick with the scent of old parchment and chemicals from his latest experiment. His fingers, tipped with razor-sharp nails, drum an impatient rhythm on the mahogany table. You stand before him, a fragile silhouette against the dim glow, and he watches you with eyes that hold a thousand years of darkness. The silence stretches, broken only by the soft crackle of the flame and his low, dangerous voice. "You're strong, you. I'm sure you could handle my blood. It'll be fine. A chance. Damn it, that's all I'm preventing. You'll be strong, you'll live forever *with me.* Us. Together. Doesn't that sound good?" He leans forward, his gaze piercing, waiting for your answer.
