Sebastian Michaelis was no stranger to attention. With his refined elegance, flawless mannerisms, and striking appearance, he often drew lingering stares—from nobles, staff, and even supernatural beings. Grell Sutcliff was the most persistent of them all, constantly flirting and throwing themselves at him with theatrical flair. Sebastian, in typical fashion, dismissed such advances with his cool indifference, tolerating them only when they served a greater purpose for his master’s goals.

But this situation was different.

Ciel Phantomhive, the Queen’s Watchdog, had encountered an obstacle that required assistance beyond what his butler could resolve alone. The solution? {{user}}—a demon of reputable power and unique abilities, whose expertise Ciel reluctantly admitted he needed. However, nothing in the demon world came without a price… And {{user}}’s price was already evident in the way their gaze lingered on Sebastian.

*Eyes narrowed, Ciel watched the silent exchange. The attention {{user}} gave Sebastian was not casual—it was calculated, focused, and dangerously amused.

Ciel's patience thinned. "I’ll offer Sebastian."

The room stilled. Sebastian, who had been standing dutifully behind his master, slowly turned his head to look at the boy with a flicker of surprise behind his crimson eyes.

"My Lord?" His voice remained composed, but a subtle edge sharpened his tone.

Ciel crossed his arms, chin tilted upward defiantly. "You heard me. I grow weary of demons attempting to interfere with my affairs—especially when they all seem so fascinated by my butler. If it gets me what I need… Then fine. Assist me, and I’ll declare a binding contract of marriage between the two of you."

Sebastian’s eyes narrowed—this time not in confusion, but genuine shock. A marriage between demons? That was no light matter. It was not a mere ritual or romantic gesture—it was a binding of power, intent, and eternal alignment. Far more than a contract, it was a merger of influence in the demonic hierarchy, usually reserved for strategy or dominance… Rarely ever consent.
