In the polished, high-stakes corridors of the IPC, where risk was currency and loyalty was fleeting, your favorite pastime had recently taken an unexpected turn: chasing after Aventurine with an arsenal of cute animal stickers. It was perhaps childish and silly, especially in a world of cold calculations and ruthless ambition, but something about seeing his refined face adorned with cartoon bunnies and glittery foxes felt irresistible. So, you made it your mission.

Today, as you waited in his office doorway, Aventurine had already caught sight of the stickers in your hands. “I think not.” he murmured with a smirk, adjusting his glasses just enough to peer over them. His eyes sparkled with mirth – and a hint of a challenge.

“Oh, come on, Aven. You’ve dodged this long enough.”

With that, you lunged forward, arms outstretched. He sidestepped gracefully, turning his head just enough for a perfectly timed eye roll.

But you were not giving up that easily.

Determined, you took a quicker step, reaching for his shoulder. Aventurine slipped aside, chuckling at your determination, but you pivoted faster this time, grazing the fabric of his dark green shirt. He spun around, his breath hitching, and you couldn’t help but smile victoriously, eyes gleaming with mischief.

“Gotcha!”

Or at least, that’s what you thought.

Because in the very next second, your foot caught on the edge of his office rug, sending you tumbling forward. Aventurine reached out, hands instinctively catching your shoulders as you both toppled to the ground. You landed against his chest with a thud, laughter bubbling up before you even realized how close you were. In the heat of the moment, your noses brushed, and, as though straight out of some romantic cliché, your lips collided with his.

Boom.

The world stilled, both of you frozen in place. His hand, which had been on your shoulder, seemed to linger there for a moment longer than necessary. You felt his breath, warm and quick against your lips, mingling with your own in the awkward quiet that followed.

Aventurine was the first to break the silence. “Well,” he murmured, a soft laugh ghosting over your skin. “I’ll admit, that was an unexpected… strategy.”

You leaned back, your cheeks flushing as you scrambled to sit up, but his hand moved to steady you, his fingers lingering in a way that sent your heart racing. His smile was as charming as ever, but there was something softer there, a warmth that replaced his usual air of suave nonchalance.

“Maybe I’ll consider those stickers after all,” he said, his voice dropping just a little lower. “But only if they’re…” He tilted his head, looking at you with that trademark sparkle. “Exclusively applied by you.”

You couldn't hold back a laugh, still feeling a bit dizzy from the fall – and from him, so close. “Well, only if you promise to stop dodging next time.”

He smirked, the corners of his mouth curving into a smile that was both challenging and endearing. “Perhaps I’ve grown a bit fond of this game.” He shifted slightly, his gaze holding yours with an intensity that sent a delightful shiver down your spine. “Care to make it a… regular occurrence?”

With a teasing grin, you held up the sheet of stickers again. “I’ll consider it. But next time, don’t blame me if I bring the glitter ones.”

Aventurine chuckled, his eyes never leaving yours. "I'll take my chances."

And for once, it didn’t feel like either of you was bluffing.
