you donât belong to him.
thatâs what makes it worse.
he looks at you like heâs already crossed the line â
youâre the only one still pretending it exists.

The gym always smelled like dust and metalâamps overheating, wires tangled like secrets no one admitted out loud.
You didnât belong there. Not really.
You werenât in the band. You didnât hang around the loud crowd, didnât laugh too easily, didnât try too hard. You just⊠existed in the spaces between things. Hallways, window seats, the back row of assemblies.
And yet somehow, you kept ending up here.
Ni-ki never looked like he belonged anywhere eitherâexcept when he had a guitar in his hands. Then everything about him sharpened. Focused. Dangerous in a quiet, deliberate way.
His fingers moved like he knew exactly what they could do to people.
You noticed that the first time you stayed too long after school.
His voice cut through the empty gym, low and impatient. The drummer groaned, but reset anyway.
You sat on the bleachers, pretending to scroll through your phone.
You werenât fooling him.
Ni-ki glanced up between chords, eyes flicking straight to you like a reflex. Like he was checking you were still there.
A nod when you passed each other in the hallway.
Then him stopping mid-conversation with his bandmates just to watch you walk byâlike he forgot what he was saying.
âWhy do you keep coming here?â
You hadnât even heard him walk up. One second you were alone, the next he was standing too close, guitar strap still slung over his shoulder.
You shrugged, not looking at him. âItâs quiet.â
âItâs not,â he said.
He was already looking at you.
Not casually. Not curiously.
Like he was trying to figure out something he didnât like not understanding.
âYou donât talk much,â he added.
âYou talk enough for both of us.â
That made something shift in his expressionâsomething sharp turning amused, but only slightly.
âCareful,â he murmured. âYou sound like you know me.â
But you didnât look away either.
That was your first mistake.
After that, he started sitting next to you during breaks.
Close enough that your shoulders almost touched. Close enough that you could feel the heat of him when he leaned forward, elbows on his knees, guitar resting against his leg.
He didnât fill the silence like everyone else did.
Like he was testing how much tension it could hold before snapping.
âYouâre always watching,â he said one day.
His fingers tapped against the guitar body, slow and rhythmic. âYou think I donât notice?â
Your throat went dry. âMaybe Iâm watching the band.â
His lips tilted, just barely. âThen why donât you look at anyone else?â
You didnât have an answer.
A girl from another class started coming to practicesâloud, bright, the kind of person who touched people when she talked.
She laughed too much at Ni-kiâs jokes.
Once, she reached out and adjusted his collar like it was nothing.
You didnât stay that day.
You left before practice ended, footsteps too fast, chest too tight.
You told yourself it didnât matter.
You told yourself he wasnât yours.
He was behind you in the hallway, voice sharper than youâd ever heard it.
You turned slowly. âI had somewhere to be.â
Ni-ki stepped closer, closing the distance like it irritated him that it existed at all.
âYou always stay,â he said, quieter now. âYou didnât even wait for me to finish.â
You crossed your arms, defensive. âYou had company.â
âShe doesnât matter.â
âDidnât look like it.â
Something in his eyes darkenedâjealousy, unmistakable and raw, but not the kind you expected.
âFor someone who doesnât talk much,â he said, voice low, âyou assume a lot.â
âAnd for someone who doesnât care,â you shot back, âyouâre asking a lot of questions.â
Your breath caught. âDonât like what?â
âWhen you disappear.â
His voice dropped, softer now, but more dangerous for it. âFeels like youâre slipping out of my hands.â
âYou donât have me,â you said, barely above a whisper.
Now there was no space left.
The way he said it didnât sound like acceptance.
It sounded like a problem he intended to fix.
After that, everything changed.
Not obvious enough for anyone else to notice.
A hand at your wrist when you tried to walk away too quickly.
Fingers brushing yours when he handed you somethingâlingering just a second too long.
Once, when you were sitting together, his knee pressed against yours and didnât move.
âSay something,â he murmured.
You swallowed. âWhy?â
âBecause when youâre quiet like thisâŠâ His thumb traced absent circles against the edge of the bench, dangerously close to your hand. âI start thinking things.â
His gaze lifted to yours, slow and deliberate.
âThat you donât feel it.â
Your chest tightened. âFeel what?â
Instead, he shiftedâcloser, closerâuntil your shoulder was pressed against his, your breath caught somewhere between in and out.
âTell me to stop,â he said softly.
But he didnât sound like he wanted you to.
You didnât say anything.
Just enough to brush against yours.
Your fingers curled slightly, instinctively reaching before you could stop yourself.
His grip tightened immediately.
âYou do feel it,â he said, almost to himself.
The almost happened the night of the school festival.
The gym was louder than usualâcrowded, lights dim, music vibrating through the floor.
Ni-kiâs band had just finished playing.
You were waiting backstage, heart still racing from watching him.
Sweat-damp hair, breath uneven, eyes already locked on yours.
âYou stayed,â he said.
Something in his expression softenedâjust for a second.
Then the tension snapped back into place.
He walked toward you, slow, deliberate.
The noise from outside faded, like the world had shrunk to just this narrow, electric space between you.
âYou looked at me the whole time,â he said.
âI notice everything about you.â
His hand liftedâhesitated for half a secondâthen tucked a strand of your hair behind your ear.
His fingers didnât move away.
They slid down, brushing your jaw.
You swallowed. âNi-ki.â
âYeah,â he murmured. âLike that.â
His thumb lingered just under your chin, tilting your face up slightly.
Your breath mixed with his.
âTell me to stop,â he whispered again.
But this time, his voice wasnât steady.
Like he was holding himself back with everything he had.
You looked at himâreally looked.
At the tension in his jaw.
The way his hand tightened just slightly, like he didnât trust himself not to pull you closer.
You shook your head, just barely.
For a second, you thought he wouldnât listen.
Then slowly, painfully, he pulled back.
His forehead rested lightly against yours instead.
âYouâre dangerous,â he muttered.
You almost smiled. âSo are you.â
He huffed a quiet laugh, breath warm against your skin.
âYeah,â he said. âBut at least I know it.â
His hand slipped into yours again.
And even though the line hadnât been crossedâ
It felt closer than ever.
And neither of you were pretending you didnât want to.
âââ ââ
ââ
â âââ
some lines arenât meant to be kept â only blurred.
next time, you wonât stop him.
âââ ââ
ââ
â âââ
late afternoons in empty gyms,
looks that linger too long,
heat that builds but never breaks
