Aventurine

In the dim light of his office, you leaned back on the sleek leather couch, wings folded gently as Aventurine sat across from you, his vibrant eyes fixed on you with that familiar playful spark. The soft glow of city lights framed his figure, lending an almost ethereal hue to his features.

"So, tell me," Aventurine leaned forward, fingers steepled, "what does an angel from the heavens need in a place like this? Surely you aren’t here to save me."

A smirk tugged at your lips. "Maybe I thought you could use a little saving, Aventurine."

He chuckled, the sound rich and smooth, like a well-aged vintage. "Oh, I’m a lost cause, trust me." His tone was light, but you sensed the depth behind it—the carefully guarded wounds he hid behind his charm and wit. As you brushed your hand across the roulette detail on his coat, you noticed his breath hitch, just for a moment.

"But perhaps…you’re not." you murmured, brushing a feather along his hand, sending a ripple of warmth over his cold skin. Aventurine’s hand slipped into yours, fingers interlocking as his eyes held yours. His usually mischievous demeanor softened, vulnerability slipping through the cracks.

"Maybe," he said, his voice softer now, "just maybe. But I think if anyone could change my mind… it might be you."

In that moment, you saw through his mask, felt his hand squeeze yours just a little tighter. And for once, Aventurine felt like more than just the gambler he pretended to be.

Sampo Koski

The streets were bustling with noise and color as Sampo sauntered beside you, his bright green eyes glinting with his usual playful mischief. You cast a cautious glance his way, aware of his reputation, but something about him—perhaps that underlying sense of survival and charm—had drawn you in, despite your better judgment.

"So," he drawled, nudging you with a grin, "an angel with clipped wings, huh? Seems we’ve got something in common, don’t you think? Both of us can’t quite keep our feet out of trouble."

You chuckled, rolling your eyes as you noticed his hand slide a little too close to your coin pouch. “Funny you’d say that,” you replied, catching his wrist. “Though I think you’re more of the rogue variety than the fallen kind.”

“Guilty as charged.” He shrugged with a shameless grin, freeing his hand but remaining close, as though walking away was the last thing on his mind.

Curiosity sparked within you as you leaned closer, wings shifting around you both like a cloak. “What if I told you I could offer you something better than coins or trinkets?”

“Is that so?” He raised an eyebrow, clearly intrigued. “And what’s that, my angel?”

You took his hand, feeling his pulse quicken beneath your fingers. “Trust, Sampo. Someone who sees through the act.”

For the first time, his laughter faltered, and he stared at you with an expression you’d never seen before—a mix of awe and hesitation. “Careful now, sweetheart,” he whispered, his tone uncharacteristically serious. “You might just get more than you bargained for.”

Dan Heng

It was a quiet night on the Astral Express. The stars glowed softly outside the window as you stood beside Dan Heng, wings folded behind you, as silent as the mystery that shrouded him. He glanced over, his blue eyes momentarily meeting yours before he returned his gaze to the starry void.

"I’m not quite sure why you’re here," he murmured, his voice low and reflective. "A place like this… doesn’t seem suited for a celestial being like you."

A soft smile touched your lips as you moved closer, reaching out to brush his hand with yours, gentle and cautious. “Fallen, not celestial,” you corrected. “I lost my way a long time ago.”

He looked at you, and in his gaze, you saw the reflection of his own scars, the history he carried but rarely shared. “And yet, you don’t seem lost,” he said. “You have… a presence.”

You chuckled softly, wings shifting. “I think we have more in common than you realize, Dan Heng. We’re both haunted by what we’ve lost, both searching for something we can’t quite name.”

Dan Heng’s gaze softened, and he allowed himself the smallest, rarest of smiles. “Maybe. But you… have given me something I didn’t think I’d find again.”

You met his gaze, feeling a warmth bloom between you as he reached out, his hand resting against your shoulder—a silent promise, a shared understanding. And there, under the glow of the stars, you knew that neither of you were as alone as you once thought.
