The sun filtered through the massive glass windows of the IPC headquarters, painting the dark wood and polished floors with golden light. Aventurine sat at his desk, lounging as if the towering pile of investment documents before him was no more stressful than a light breeze. His eyes scanned over a datapad, but his mind was elsewhere.

Specifically, it was on you.

You had shown up this morning in his office as you always did, bearing a little box wrapped in shimmering paper. Inside was a bracelet: delicate chains of gold intertwined with tiny gemstone chips that sparkled like stars. You had said it reminded you of him—his shine, his brilliance, his ability to make even chaos look beautiful.

And now that bracelet sat snugly on his wrist, hidden beneath the cuff of his blazer sleeve. No one would know it was there, but Aventurine could feel its weight.

The thought of you crafting it made his chest ache with an emotion he often buried under charm and strategy. It was vulnerability—a sensation far more dangerous than any bet he had ever placed.

That evening, you sat cross-legged in your little workspace, a tray of tools and half-finished designs spread out around you. Aventurine had slipped away from his work early and stood quietly in the doorway, watching as your fingers deftly threaded silver wire through a small emerald bead.

"Do you ever rest?" His smooth voice broke the silence, making you jump slightly.

You looked up, smiling as you placed the half-finished earring on the table. "Rest is overrated when inspiration strikes. Besides, I have a certain someone who keeps my creativity alive."

He chuckled, stepping into the room and inspecting the scattered pieces. The light glinted off the glasses perched on his nose, their rose-tinted lenses casting a faint glow over his cheekbones.

"You spoil me," he said, picking up a necklace draped with charms shaped like playing cards. "This one’s new, isn’t it? A touch of luck for your favorite gambler?"

"Luck and love," you teased, standing to face him. "But I don’t think you need the former when you’ve got the latter."

The words caught him off guard, his usual quick-witted responses faltering. You were one of the few who could do that—strip him of his carefully constructed layers and make him feel seen. He reached out, his gloved fingers brushing a stray hair from your face.

"You make me reckless," he murmured, his smile softer than usual. "And I think I like it."

A week later, Aventurine sat across from you at a bustling café. The world outside was cold and dreary, but here, the warmth from the drinks and the glow of your presence made it feel like summer.

You handed him another little box, your grin playful. "Go on, open it."

Inside was a set of cufflinks shaped like tiny roulette wheels. The craftsmanship was exquisite, the enamel shimmering in shades of black and red. He held one up, his lips quirking into a smile.

"Let me guess," he said, "you’re trying to rig my odds?"

"Only in your favor." you replied.

He leaned back, twirling one cufflink between his fingers. "You’re dangerous, you know. Giving me trinkets like this—it’s like you’re branding me as yours."

"Good." you shot back, sipping your drink with a wink.

For a moment, he said nothing, his gaze steady and intense. Then he reached across the table, his gloved hand covering yours.

"I’ve lived my life on the edge of losing everything," he said quietly. "But you... you make me think there’s something worth keeping."

Your cheeks flushed at the rare sincerity in his voice. "Then hold onto me." you whispered.

He didn’t need to say anything more. The look in his eyes—the same daring, confident glint he wore in the heat of high-stakes deals—said it all. Aventurine wasn’t a man to gamble on something unless he believed he could win. And with you by his side, he felt invincible.
