Dan Heng

Dan Heng sat in the dimly lit cabin of the Astral Express, the rhythmic hum of the train the only sound that accompanied his solitude. He had always found solace in the quiet, preferring it to the bustling noise of crowds or the endless chatter of others. Yet, tonight was different. His mind was clouded with thoughts of you, the artist who had been a silent but ever-present figure in his life since the day he met you.

The first time he laid eyes on you, it was nothing more than a fleeting moment—one he hadn't thought much of at the time. But it was strange, wasn't it? How that moment stayed with him, replaying in his mind like an image he couldn't shake. He had never been one to dwell on emotions, and yet something about you made him want to linger, if only in the shadows, far away from the spotlight.

Dan Heng didn't understand what had changed. He wasn't someone who sought out attention, let alone affection. And yet, as he watched you work from afar, sketching, painting, your every movement seemed to haunt him. His heart would beat just a little faster whenever you were near, though he could never bring himself to speak those words aloud.

He found himself drawn to your art. The way you captured the world around you, the strokes of your brush that seemed to tell stories even without words. There was a certain intensity in your work—an emotional rawness that he couldn't ignore. He often found himself admiring your paintings when you weren’t around, noticing how every canvas seemed to glow with your feelings.

It was late into the night when he stumbled upon your most recent piece. His heart skipped a beat as he studied it, entranced by the use of color—vibrant, soft hues blending together in ways that felt… familiar. It wasn’t just a painting. It was a confession, a revelation.

The subject of the piece was unmistakable. It was him.

You had painted him—his profile, his features, his soul—captured in every brushstroke. But it wasn’t just the image that left him breathless. It was the colors, the warmth that spilled from the canvas. The shades of blue, gold, and soft pinks spoke of longing, of something deeper than simple admiration. It was a language he understood but had never expected to see expressed so vividly.

He didn’t know what to feel. His initial instinct was to run, to distance himself from this vulnerability you had so willingly shared through your art. But something inside him stopped him. He couldn’t tear his eyes away from the painting, and he certainly couldn’t tear himself away from you.

The confession was out now, laid bare in the colors of your love. The quiet admiration, the unspoken feelings—it was all there, framed on the canvas in front of him.

Dan Heng sighed, a soft exhale of air escaping his lips as he stood before the painting. For the first time, he allowed himself to feel the weight of what he hadn’t dared to acknowledge. And maybe, just maybe, he could find the courage to speak those words too, to paint his own feelings for you.

But for now, he stood still, his gaze locked on the painting of the one person who had quietly captured his heart without him even realizing it.

Sunday

Sunday sat in the quiet of his room, a flickering candle casting soft shadows across the walls. His fingers drummed lightly on the desk, a slight frown on his face as he looked at the painting in front of him. It was a recent creation of yours, the artist he had come to know and admire, even though he had never once admitted it aloud.

It had begun innocently enough—your work, a collection of serene landscapes, abstract expressions of peace and stillness. But as he continued to observe you, there was a shift. Your art had changed, taken on a more personal tone. It wasn’t just about capturing beauty anymore. It was about capturing something much deeper, something you didn’t quite show anyone else. The passion in your strokes had transformed, and Sunday couldn’t ignore it.

The latest piece was a reflection of his own face. His figure was painted in muted hues of silver and violet, colors that mirrored the ones that seemed to haunt him in his dreams. But it wasn’t the likeness that struck him the most; it was the emotion woven into every brushstroke. There was love in the way the colors swirled, an emotion so tangible it seemed to bleed from the canvas.

It was as if you had captured every fleeting moment of their encounters—the way he smiled at you with a hint of warmth, the way his gaze lingered a moment too long. You had woven all of it into this painting, turning their quiet moments into something that felt like poetry, like a love song without words.

For a long while, Sunday simply stared at the painting, his thoughts a whirl of confusion. He had always believed in the Sweetdream Paradise, a world where people could escape their pain. But this… this felt different. It felt real, like a dream he didn’t want to escape, one he wasn’t sure he was ready to face.

Was this your way of confessing? The idea that someone could love him—the person who had always distanced himself from true connection, who had always preached the merit of a painless, perfect world—seemed impossible. And yet, there it was, in front of him.

The painting was more than just art. It was a message, a way of saying what neither of them had yet dared to speak aloud. You had used your work to tell him what was in your heart, and now, he had to decide if he could find the courage to do the same.

The weight of the moment hung in the air, heavy with unspoken words. As he reached out to touch the canvas, a sense of longing surged within him—something that hadn’t been there before. Perhaps, in this moment, the dream of escape no longer felt as appealing as the dream of something real. Something tangible. Something he could finally reach for.

He closed his eyes, allowing himself to imagine a future where the colors of love—your love—were the only ones he ever saw.

Aventurine

Aventurine sat in his private study, the dim light of the lamps casting shadows on the room’s elegant furnishings. His fingers idly turned a deck of cards as he gazed at the newest painting displayed on the wall—a work of art that had both mesmerized and unsettled him. The colors, the brushstrokes, the way your soul seemed to be embedded in every layer of paint—he had seen many paintings in his time, but none like this.

The subject was unmistakable. It was him.

But this was not a simple portrait. No, this was far more. It was raw. It was a confession wrapped in the hues of the artist’s emotions. His face, framed by dark shades of green and gold, looked almost serene, yet there was something deeply intimate about it. The delicate touches of rose and violet reflected a softness that made his heart beat just a little faster.

He had always prided himself on being able to control everything—every move, every decision, every game he played. Life, to him, was a high-stakes gamble, a game of strategy and manipulation. But here, with this painting, everything felt out of his hands. This wasn’t a game. This was real.

Aventurine had always been surrounded by beauty, charm, and a sense of power, but there was something different about this. It wasn’t the typical adoration or fascination he was used to; no, this was love—true, unfiltered love. And somehow, it was aimed at him.

His gaze lingered on the painting, every brushstroke sending a jolt through his chest. He wondered if this was your way of confessing, of revealing the feelings you had hidden beneath the surface. He hadn’t expected this, not from someone like you, someone who had always remained so distant, so reserved. Yet here it was, in full view—a revelation he could no longer ignore.

He had been careful with his emotions, always keeping them locked away behind a facade of confidence and control. But this… this painting had cracked that facade wide open. He couldn’t deny it any longer. The truth was there, laid bare on the canvas, just as much as his own heart was.

Aventurine smiled, a rare, genuine smile that softened his usual playful demeanor. Maybe, just maybe, this was one game he wasn’t so keen on playing alone. Perhaps it was time to place his bet—not with cards, but with his heart.

And when the time came, he would show you that his feelings were not a gamble, but a certainty.
