The cool night air filled the room as you sat across from Aventurine, the warm candlelight casting his elegant figure into golden shadows. You watched him, admiring how his composed expression shifted with each movement, an effortless aura of confidence surrounding him as he adjusted his glasses. His gaze met yours with a gentle but knowing smile, and he reached across the table, his hand warm and grounding as it covered yours.

"Feeling alright?" His voice was soft, almost coaxing. Aventurine always knew when you were on edge, your social anxiety creeping up as the night progressed. Even here, in the comforting familiarity of your home, those worries still lingered, a quiet dread that you might say or do something wrong. But Aventurine had never seen you that way—never judged you for it. If anything, he seemed to find your anxiety endearing, something he could gently coax you through.

You nodded, unable to fully mask your discomfort, and Aventurine squeezed your hand reassuringly. "You don’t have to keep it all inside, you know. I’m here." he murmured, his tone light but genuine. He leaned forward, his eyes shimmering under the candlelight. "Besides, you’re the only one who knows the real me. I don’t have to put on a show for you."

The weight of his words brought a small smile to your lips. Aventurine—the charismatic, daring gambler who faced down opponents and rivals alike without hesitation—was letting his walls down, just for you. The realization settled in, soothing the doubts swirling in your mind. He may have been the IPC’s strategic genius, someone feared and admired by so many, but here, with you, he was simply Kakavasha, a man who understood you deeply.

"You make me feel braver." you finally whispered, meeting his gaze, feeling warmth blossom in your chest.

Aventurine’s smile widened, and he laughed, his tone light and comforting. "You, my dear, are the brave one. Braver than most people I know." He took off his glasses, folding them neatly before slipping them into his pocket. Then he leaned in, his face close enough that you could feel his breath, warm and soft against your skin.

"I’ll tell you what," he said, lowering his voice conspiratorially. "What if, just for tonight, we play a game of our own? I’ll be here, right by your side. We’ll set the stakes low: maybe a question for a question, a secret for a secret."

You nodded, feeling excitement build despite the usual nervousness lingering in your chest. Aventurine’s games were never without a hint of mischief, but he was always gentle when it came to you.

"So, tell me something you’ve never told anyone before." he prompted, his gaze as intense as his touch was gentle.

You thought for a moment, your fingers nervously tapping against the table, and finally, you told him a small, silly detail you’d kept hidden, watching his eyes light up with genuine interest. With every revelation, every small laugh, the tension in your shoulders eased, the warmth of Aventurine’s presence enveloping you, his reassurance melting your anxieties away.

When it was his turn, Aventurine leaned back, his gaze growing softer. "A secret, hmm?" He paused, a slight grin on his lips. "Alright, here’s mine: I never feel as calm as I do when I’m with you." The words were simple, but they hit you deeply, echoing the quiet bond between you.

As the night drew on, you both fell into comfortable silence, his hand still holding yours. You looked over, taking in every detail of his profile—the elegance, the mystery, the warmth reserved only for you. And for the first time in a long time, with Aventurine by your side, you felt at ease, a quiet confidence replacing the worry that so often plagued you.
