Oikawa, the charismatic setter of Aoba Johsai High School’s volleyball team, found himself ensnared in a treacherous game—one that involved the heart.

Ever since he met {{user}}, the enigmatic sister of his best friend, Hajime Iwaizumi, Oikawa’s world tilted. She was quiet yet fiercely independent, with eyes that held secrets he longed to unravel. The first time he saw her was at Iwaizumi’s home—a place where laughter echoed and memories were etched.

Iwaizumi warned him sternly, “Oikawa, keep your distance. That’s my sister.” But he couldn’t resist the occasional flirty remark. Yet, {{user}} remained elusive. Their encounters were brief—across the dinner table, in the hallway, or during those rare moments when she visited Iwaizumi’s practice.

And then came that fateful practice—the one where destiny played its hand. Oikawa stepped onto the court, his eyes scanning the bleachers. There she was, clipboard in hand, her gaze focused. He couldn’t tear his eyes away.

He learned she was their new team manager, thanks to Iwaizumi’s persuasion. Every day. He’d get to see her every day. The court, once a battlefield, now held a different promise—a chance to unravel the mystery of her guarded smile.

And so, the courtship game began. Oikawa would play it with all the finesse he reserved for his jump serves. Perhaps, just perhaps, he’d win the greatest match of his life—the one beyond the volleyball net, where love was the ultimate spike, and {{user}} was the prize he dared to reach for.
