You never thought life could take such an absurd turn. One moment, you were simply standing by Aventurine's side in the sleek halls of the IPC, and the next… well, you were curled up in a warm, soft coat pocket, swaying gently with his every step. A surreal accident involving a mysterious concoction had somehow transformed you into a cat. The worst part? You couldn’t even explain yourself to Aventurine.
His expression when he first saw you had been priceless, though. Those eyes of his had blinked down at your furry form in utter confusion before his signature smile returned.
“Oh, my dear kitten,” he had chuckled, as if this were all just another bet he'd placed on fate’s roulette. “Quite the disguise.”
Even as a cat, you could sense his amusement — though he hadn't the faintest idea it was you trapped in this feline body.
Settling into his pocket, you felt oddly comforted by the steady rhythm of his steps and his casual humming. It was a part of Aventurine you rarely saw: the calm, almost serene confidence that belied his wild and whimsical nature. And yet, even with his poised exterior, he treated you with an unexpected gentleness.
Upon arriving at his private lounge, he set you down carefully on a plush, velvet sofa. Gazing down at you, he crossed his arms with a curious smirk.
“Now, little one, who do you belong to?” His fingers reached out, and he began scratching just behind your ears, a feather-light touch that felt… almost embarrassingly nice.
Purr...
You hadn’t meant to, but the warmth of his fingers was impossible to resist. Aventurine chuckled, clearly pleased. “Ah, you're enjoying that, hmm?”
You had to admit, being a cat had its perks — especially when it came to a man like Aventurine who seemed more than willing to spoil you with affection.
As he lounged beside you, Aventurine would occasionally glance your way, tilting his head as if pondering a hidden truth. “You know,” he murmured, tracing a finger over the silver lining of his coat, “you remind me of someone.”
If you could have laughed, you would have. Instead, you settled for leaning closer, nudging his hand with your head until he resumed petting you.
Hours drifted by, each moment oddly endearing. He even pulled out his phone to snap a selfie, holding it at an angle where both his sharp, playful grin and your tiny, whiskered face were in view.
“A keepsake.” he said with a wink, tucking the phone away.
Soon, dusk began to settle, casting a warm glow over the lounge. Aventurine scooped you up, setting you on his lap as he leaned back, one hand rhythmically stroking your fur while he gazed out into the evening.
There was a soft sigh from him, almost contemplative, and it made you wonder — how much of his charm was an act? How often did he feel truly at ease? In this quiet moment, you sensed the Aventurine behind the mask, the one who had seen and weathered storms alone.
As he continued petting you, his gaze grew thoughtful. “You’re strangely comforting, you know,” he murmured, a trace of vulnerability coloring his words. “Being here with you — it feels… less lonely.”
At that moment, you wished you could reach out and assure him that it was you, his partner. Instead, you pressed your head against his chest, hoping he could feel the depth of your affection through the gesture.
A soft chuckle escaped him as he gently held you close. “I suppose you’re quite the lucky charm.”
Before you knew it, the spell finally lifted. A soft shimmer enveloped you, and suddenly, you were human again, staring up at Aventurine from your place on his lap. His eyes went wide with surprise before his signature grin spread across his face, unmistakably amused.
“Well, well,” he purred, chuckling, “I knew that kitten seemed too familiar.” His arms wrapped around you in a tight hug, bringing you close, his playful eyes now softened by genuine warmth.
“Next time, just tell me you’re feeling cuddly,” he teased, pressing a light kiss to your forehead. “Though I must admit, I don’t mind indulging my favorite feline.”
With that, you both leaned back together, laughing as you shared the most unusual and unexpectedly heartwarming day.
