it wasn't a particularly rare night to spend by atsumu's side. galas and formal events had become a familiar backdrop to your relationship, a stage where you often played the role of his elegant plus one. yet, tonight was just— different. from the moment the sun peeked over the skyline, painting the morning with hues of orange and gold, a radiant smile had taken permanent residence on atsumu's face. it lingered through breakfast, during the car ride, and even now, under the dazzling chandeliers of the ballroom. it was a smile that hinted at a secret joy, a silent celebration you weren't privy to.

as the evening progressed, the air crackled with the usual mix of polite chatter and clinking glasses. atsumu navigated the crowd with his characteristic charm, his hand a warm anchor at the your back. then came the inevitable request for a live television interview. you'd stood beside him countless times, offering a supportive smile to the camera, but tonight felt different. his grin was wider, his eyes held a mischievous glint as he casually pulled you closer into the frame.

"anyway," he began, his voice smooth and confident, "i wanna take this moment to highlight my biggest supporter, my fiancée— wait, what did i just say?"

a ripple of surprise went through the room, a collective gasp that mirrored the sudden flutter in your own chest. just then, the unmistakable opening chords of Bruno Mars' "Marry You" filled the air, a playful melody weaving its way through the stunned silence. your gaze flickered towards the small orchestra in the corner, a question mark etched on your face. but when you turned back to atsumu, the world seemed to tilt.

he wasn't standing beside you. he was kneeling, one knee gracefully touching the polished marble floor. in his outstretched hand, nestled in the soft glow of the spotlights, sat a ring. the playful grin had softened, replaced by an expression of pure adoration. his eyes locked with yours, and in that moment, the noise of the gala faded away, leaving only the two of you in a bubble of anticipation.

"well, baby," he said, his voice a little husky, a tremor of emotion underlying his usual confidence, "this is it."

he took a deep breath, his gaze unwavering. "you're my final set. my match point. my forever. i used to wish the world would end every day, so i'd have an excuse to show up at your door and just, kiss you, because it'd be our last day on earth. but for years now, i've gotten to hold you, kiss you, love you boundlessly, and i'd do it all again if it'd meant you'd be mine."

his surprise was undeniably effective. the sheer audacity of it, the public declaration, the unexpected serenade – it all collided in a wave of shock that left you momentarily speechless.

his eyes searched yours, a silent plea etched in their depths. "so, will you marry me?"
