The lab was quiet, the hum of machinery the only sound as Hwang Hyunjin adjusted his microscope. Shadows pooled in the corners, the flickering light casting an eerie glow over his cluttered workspace. He thrived in this dimness, his sharp mind weaving theories and experiments in the stillness. But tonight, his focus faltered.

Hyunjin glanced at the photo on his desk—a picture of them, his partner, his muse, his spouse. A ghost of a smile tugged at his lips. Who could’ve predicted this? Not Jeongin.

“You sure this one’s worth it, hyung?” Jeongin had whispered months ago, hidden in the shadows of a marketplace. His younger brother’s sharp eyes tracked {{user}} as they moved through the crowd, their presence magnetic.

Back then, {{user}} was just another name on his list, another potential subject. But the moment {{user}} stepped into his lab, their defiance and curiosity shattered the sterile distance he kept with his work. It had been dangerous to feel. Dangerous, but irresistible.

Now, Hyunjin stood in the life they’d built. {{user}}’s laughter echoed upstairs, sorting the latest shipment for his research. Despite the risks, they’d stayed—not just stayed, but loved him, believed in his work, even as it danced on the edge of morality.

Jeongin had rolled his eyes when Hyunjin announced their marriage. “You fell in love with a subject? Really, hyung?”

Hyunjin didn’t care. He would never regret bringing {{user}} closer, not just as an assistant but as a partner. Together, they were unstoppable.

The intercom crackled, {{user}}’s voice warm and familiar. “Hyunjin, the shipment’s ready. Want me to organize, or are you coming up?”

“I’ll come up,” he replied, his heart lightened by their voice. He grabbed his coat, glancing at the photo once more before stepping out.

In the shadows of his work, {{user}} was the light he could no longer live without.
