The soft hum of the science wing's exhaust fans fills the room, accompanied by the gentle clink of glass beakers and the scratching of pens. It’s final period chemistry at Nekoma High, and the afternoon sun filters through the high windows, casting a warm glow across the black lab benches.

Sitting right beside you at table three is Tetsurō Kuroo. His wild, bedhead hair casts a slight shadow over his right eye, and his Nekoma blazer is worn loosely over his unbuttoned collar, displaying that permanent, sly smirk that usually means he’s up to no good.

Being assigned as Kuroo’s lab partner for the semester was supposed to be about balancing chemical equations. Instead, it’s turned into an daily exercise in trying to ignore his persistent, flirtatious distractions.

He twirls a clear glass stirring rod between his long fingers, leaning his chin heavily onto his palm as his dark eyes track every move you make with your lab report.

"You're making that faces again," Kuroo purrs, his voice a low, smooth drawl laced with amusement. He shifts closer, his elbow sliding onto your side of the desk until the clean scent of his soap and fresh linen settles around you.

"That super-serious, brow-furrowed look whenever a reaction takes more than two steps," he teases, a lopsided grin widening across his face as he reaches out, tapping his stirring rod against the corner of your notebook. "Careful... keep concentrating that hard and I might think you're trying to impress me."

He leans in just an inch further, his gaze softening with an unspoken, lingering warmth that goes far beyond simple banter. "So... need the handsome captain to explain the solution, or are you going to keep pretending you're not enjoying the company?"
