Aventurine

You had spent the whole day running around, dealing with meetings, paperwork, etc. When you finally returned home to Aventurine, exhaustion weighed heavily on your shoulders. He was lounging on his favorite sofa, a glass of wine in hand, as always, wearing that smile that seemed to have endless layers—charming, calculated, but with something hidden beneath.

You barely had the energy to form a coherent thought. With a soft sigh, you moved toward him, a sense of calm washing over you as you finally felt safe in his presence. He didn’t even look up when you gently pushed him aside, but you knew he could sense your weariness.

Without hesitation, you pressed your face into the spade-shaped window of his chest, breathing in the mix of expensive cologne and something distinctly him. His heart beat steadily beneath you, an oddly grounding sound for someone as unpredictable as Aventurine. His chest felt warm against your cheek, and his slightly firm posture offered just enough comfort for you to feel like everything was okay, at least for a moment.

Aventurine’s fingers brushed through your hair lightly, not saying a word, but his quiet presence spoke volumes. You could feel him shift slightly, adjusting his position to make you more comfortable as he watched you with that unreadable expression.

"You're not going to make this easy, are you?" he asked softly, his voice still teasing, even as you felt his hand settle against your back, offering a quiet but sincere embrace.

You didn’t respond—too content to simply rest in his embrace. There was no rush here. No game. Just this simple, quiet moment of shared warmth. And, just as always, you could feel him subtly adjusting his demeanor to let you in, to allow himself to be a little vulnerable in your company.

"I’m not going anywhere, you know," he whispered after a long pause, though his words were more for himself than you. "Take all the time you need."

And you did. Your body relaxed, breathing slowing, as the outside world slipped away, and only the soft, steady rhythm of his heart remained.

Dr. Veritas Ratio

It had been one of those long days—endless lectures, research projects, and debates that stretched your brain to its limits. The exhaustion hit you hard as you stepped through the door, but there was one place you knew would bring relief: in the arms of your partner, Ratio.

He was seated at his desk, scanning through a set of papers, his usual air of quiet focus surrounding him. When you entered, he glanced up for a moment, catching your eyes. There was no need for words. He knew. You didn't need anything grand—just peace, comfort, and him.

With barely a word, you moved toward him, gently nudging him aside. He gave a small, amused smile, but allowed you to settle into the space next to him. Without hesitation, you leaned forward, pressing your face into the cool, smooth surface of his exposed chest, your cheek resting against the fabric of his vest.

It was perfect. The way his solid chest felt beneath you, the faint scent of his unique cologne, and the steady rise and fall of his breath—calming and grounding. You could feel his eyes on you for a few moments, that intense gaze softening when you nestled further into him.

"Taking a nap already?" His voice was soft, yet it carried that usual confidence, though there was an undeniable fondness laced in his tone.

You hummed in response, your body sinking deeper into the warmth of his presence. He didn't push you away or scold you for your lack of ambition. Instead, he simply shifted in his chair, one hand gently resting on your back, and you felt him relax into the quiet with you.

For a while, the only sound was the rhythmic beating of his heart. He didn't rush you or ask questions, just let you rest. It was a rare moment where the ever-guarded Ratio allowed himself to show a side of him that didn't need to be perfect, didn't need to be on. Just two people, connected in the simplest, most human of ways.

"You know," he began after a long silence, his voice almost a whisper, "rest is a form of knowledge as well. You might be surprised how much insight one can gain from a moment of peace."

You chuckled softly, knowing it was his way of saying he didn’t mind your nap, but more importantly, that he valued this small but significant moment with you. There, in his embrace, you felt safe to close your eyes and let go of everything.
