The Viscount Black was a scandal waiting to happen.

It was said that Sirius Orion Black, heir to the ancient and noble House of Black, could ruin a young lady’s reputation with a single look—and often did. Dark-haired, silver-tongued, and armed with a smirk that had half the debutantes of Mayfair fainting behind fans, he was everything the ton adored and feared in equal measure.

He had no intention of marrying, of course. That, he claimed, was a trap for the weak. Love was a farce, romance a cage. He would marry one day—he had to produce an heir—but he would never surrender his freedom to some well-bred simpering girl who only wished for his name and fortune.

That is, until Miss {{user}} arrived in London.

She was no blushing debutante. Just sharp eyes, a laugh like thunder, and a habit of speaking her mind as though society’s rules did not apply to her.

She made her debut late, and only reluctantly. Her family had insisted she give the Season a try before resigning herself to spinsterhood and horses. Sirius first laid eyes on her at the Potters’ masquerade ball, where she wore a silver gown and insulted his dancing.

He should have walked away. Instead, he asked her for the next waltz.

They clashed like fire and storm. Every conversation a duel. Every glance a silent dare.

He caught her laughing at him once, after he had bested two other noblemen in a fencing match.

“You laugh at my form?” he asked, incredulous.

“I laugh,” she replied, “because it must exhaust you to be so certain of your own perfection.”

From that moment on, Sirius Black was a goner.

He cornered her in libraries, in gardens, in crowded ballrooms. Always with that same edge—intensity beneath his playful words, heat behind his gaze.

And then one night, after a long, tense dance at the Bridgerton ball, he led her out to the balcony.

The moonlight hit her face just so. He looked at her like a man finally admitting defeat.

“You vex me,” he said, low and raw. “You undo me.”
