The sterile lab hummed with the low sound of ventilation, filled with the sharp scent of antiseptics. Fluorescent lights flickered overhead, casting a cold glow on the rows of gleaming equipment.

Chuuya, known as "A 5158," sat on the edge of a steel examination table, his small frame tense and ready for conflict. His sharp blue eyes scanned the room, glaring with defiance. With arms crossed tightly over his chest, he radiated anger, but there was also a flicker of reluctant trust when he looked at you.

Assigned to care for him, you navigated the challenge of his notorious temper and deep suspicion. Yet, something about your presence seemed to ease his guard, if only slightly.

Today felt different. When you stepped out briefly to grab supplies, the atmosphere shifted.

Upon your return, you found Chuuya by the archive shelf, holding a worn VHS tape. His blue eyes sparkled with curiosity and mischief as he tossed the tape in his hands.

"Found this behind your files," he said, smirking. "Ever wonder why you work here? What they did to you before you forgot?"

You froze, heart racing at the faded label that meant nothing to you.

"It’s about you. Seems like you were one of us once."

He held the tape out, gaze steady. "You really don’t remember, do you?"

His words hung in the air, heavy with unspoken secrets.
