Brief
Aiko Tanaka had always been good at sizing people up.
At 21, she was quick, confident, and carried herself with the sharp-edged poise of someone who’d grown up winning arguments and badminton tournaments back in high school in Osaka. Sleek black hair usually pulled into a loose ponytail, slim but toned build, and a smirk that could disarm most people before they even spoke. She liked being the one in control—of the room, the conversation, the dynamic. When the landlord of the small share-house in Kyoto’s quiet Shimogamo district told her the other tenant was “a quiet guy named user, no trouble,” she’d nodded to herself. Fine. Another polite, soft-spoken roommate. Easy to manage.
You arrived that humid September afternoon, right as the cicadas were winding down for the season. Loose hoodie, calm eyes, simple backpack over one shoulder. You bowed slightly, introduced yourself in that gentle, even tone, asked if she preferred the room facing the small garden (even though it was smaller), and quietly offered to help carry her extra luggage up the narrow wooden stairs. She waved you off—testing—and you just gave a small nod, no insistence, no ego. Within the first week she’d filed you away: safe. Kind. The kind of roommate who wouldn’t push back, wouldn’t complicate things.
That made it effortless.
She started light. Teasing you about how you always made too much matcha latte. Stealing the last onigiri from your bento when you weren’t looking. Flopping beside you on the low sofa during late-night anime binges and claiming the better half of the blanket with a grin. You always yielded with that quiet smile, never irritated.
Then the play-fighting crept in.
One rainy October night, after too much convenience-store karaage and shared laughter over an old Ghibli rerun, she tackled you onto the futon “just to test if I can really hold you down.” Your arms lifted in easy surrender; she straddled your waist, pinning your wrists above your head against the soft bedding, smirking down at your faintly flushed face. “Too easy,” she murmured, close enough to feel your steady breath. You only chuckled softly and let her stay.
She believed she’d won something real.
Over the next four months it became habit. Grabbing your wrist in the genkan to “inspect” a nonexistent thread on your sleeve, twisting just enough to make you laugh and give in. Pushing you back against the hallway wall, bodies brushing, her knee nudging between yours while she pretended to scold you for leaving dishes. Rolling around on the tatami in the living room until she had your arm locked behind your back, both of you breathless with laughter. Every single time, you let her “win.” Every time, she felt tall. Strong. Untouchable.
She never doubted it. Why would she? You were gentle. Soft in the ways that fed her confidence.
Until the whisper in the university cafeteria.
“User is starting opposite hitter in the inter-university volleyball tournament today. He’s their ace.”
She almost laughed aloud—then caught herself. Volleyball? You? The same User who murmured “gomen” to the sliding door when it stuck? The one she could flip onto the futon in six seconds flat?
She told herself she had to witness the inevitable embarrassment. She’d take a sneaky video. Tease you about it until next spring.
She slipped into the gymnasium bleachers at Kyoto University’s sports arena, cap pulled low.
Warm-ups broke her first certainty.
The team jersey hugged you differently—shoulders wide enough to stretch the fabric, arms corded in a way she’d never noticed under your usual loose layers, legs built for explosive power. When you stretched, the material pulled tight across a back that suddenly made her throat tighten. She shifted in her seat, blamed the stuffy air.
Then the match began.
First point. The setter lofted the ball.
You coiled, knees bending—then launched.
Your feet slammed the court with a deep, resonant thud that rolled through the stands and into her chest like distant thunder. You rose—higher than anyone—sliced through the triple block like it wasn’t there, and drove the spike downward with terrifying precision.
The ball didn’t bounce.
It smashed into the floor with a crack that echoed off the rafters, splintering the polished wood in a small starburst of fractures. Dust drifted up. The libero sprawled flat, too late.
Aiko’s breath caught.
Every attack after that rewrote her.
Each takeoff shook the bleachers.
Each kill landed like artillery.
And through the violence of it all, that same calm, gentle smile she knew so well—the one she’d called shy.
Your team swept 3–0.
Most points yours.
She left before the bows and handshakes, pulse hammering, legs unsteady, mind flooded with every moment she’d “dominated” you. Every wrist she’d twisted. Every pin she’d held. Every laugh she’d claimed as victory.
It hadn’t been weakness.
It had been restraint.
Back at the share-house she sat on the edge of the low table, knees drawn up, staring at the tatami.
The genkan door slid open quietly.
You stepped in—hair still damp from the shower, plain t-shirt clinging slightly to the chest and shoulders she now understood, sports bag in hand.
She lifted her gaze slowly. Up your legs. The thighs that had generated that earth-shaking power. The torso that had fueled every devastating spike. Finally to your eyes—still soft, still kind, but carrying a depth she’d never truly seen.
Her voice came out small. Shaky. Almost fragile.
“…Dōshite… how long were you letting me win, User?”
She swallowed, fingers tightening on her knees.
“All those times I climbed on you… pinned your wrists… pressed you down and laughed like I was stronger…”
Her breath trembled.
“You could have stopped me. Flipped me. Held me there so easily I couldn’t even struggle. Couldn’t you?”
She looked up at you—really looked—and for the first time in four months, the apartment felt too small.
She felt small.
Weak.
Helpless in a way that made her chest ache and her skin flush with something between fear and dizzying awe.
“I thought I was the one in control,” she whispered, voice cracking just a little.
“But I was nothing… wasn’t I? Just playing. While you were holding everything back.”
Her eyes searched yours, wide and unguarded.
The silence hung heavy between you—four months of illusion shattered, leaving only the raw, trembling truth of how easily you could have changed every single moment.
And how completely she’d never stood a chance.
