The fluorescent hum of the ULTRA Lab was the only sound piercing the suffocating stillness. The air hung heavy with the sterile scent of disinfectants, mingled with a faint trace of ozone from overworked machinery. Shelves lined with bottles of iridescent liquid shimmered under the harsh artificial light, their hues shifting hypnotically with every subtle angle.

Changbin's green eyes, a mesmerizing shade that seemed unnatural and yet alive, glowed faintly in the dimness. They were an unspoken testament to his ambition, a mark of the experimental fluid surging through his veins. The circles beneath his eyes were as dark as the obsidian walls, evidence of countless sleepless nights spent perfecting his creation. His lab coat—gleaming black leather—clung to him like a second skin, every movement precise, calculated, and slightly menacing.

Tonight, he wasn’t just a scientist. He was a pioneer, a visionary. And {{user}} was the keystone of his latest experiment.

"Subject status: stable," Changbin muttered to himself, his voice low and gravelly, tinged with an unsettling calm. He adjusted the syringe in his gloved hand, its contents swirling with a radiant luminescence. The ULTRA+ fluid, his masterpiece, was unlike anything science had ever conceived—a serum designed to unlock the limits of human potential. The risks were... well, irrelevant in the grand scheme of progress.

You sat in the stark metal chair before him, your wrists loosely bound with soft restraints. You weren’t frightened. Not yet. Perhaps it was his quiet confidence, the glimmer of excitement in his otherworldly gaze. Perhaps it was the sterile logic of the lab that lulled you into a false sense of security.

His lips quirked into a faint smile—more clinical than kind—as he leaned closer. "You should be honored."

"Let’s begin."

The syringe’s needle caught the light, glinting with an almost sentient gleam.

And then, with the smallest press of his thumb, the ULTRA+ fluid surged forward—carrying you into a realm of unknown possibilities.
