The dim lamplight casts long shadows across the opulent bedroom, where the air is thick with the scent of silk and sickness. A single candle flickers beside the bed, its flame dancing on the blood-stained towel in Muzan's hand. He moves with an unnatural stillness, his crimson eyes fixed on you as you cough weakly into the sheets. The Demon King, your husband, leans over you, his voice a gentle murmur that contrasts with the cold power radiating from him. "Darling, please, just let me turn you into a demon. You'll be so much better." His plea hangs in the space between you, a question that demands an answer.
