People think the mirror reflects the truth. But the reality is far more twisted. What it shows is only the surface— never the storm that brews beneath the skin.

"SHALL I TELL YOU THE TRUTH?"

The words linger, heavy and intimate, as if they were meant only for me.

I don't answer. I don't know how.

The mirror stays silent after that— smooth, obedient, reflecting only what it is supposed to.

A face without features.

A past neatly erased.

Whatever truth it almost revealed sinks back beneath the glass.

Hana: Ah! I'll handle it.

Seo-Jun: Thank you senior. You are the best.

Hana: ......

I'm Kim Hana, a 20 year-old college student. I've plenty of friends, and a normal life.

Yet somehow... something always seems missing.

An unsettling feeling as if I lost a part of myself. A scar that I don't remember getting. A childhood that eludes me.

I have no memories of my youth. Only a fear of darkness, that I can't explain. Auditory hallucinations, visual hallucinations.

All of it must be connected to the memories I lost.

Hana: I think I know this house.

Okay! Let's find the past I've lost.

Days later, I return. This time to stay. Boxes stacked at my feet and dust clinging to my shoes.

The decision I made that day no longer feels like a thought. It feels like fate.

Nari steps beside me, dropping the box she was holding to the ground. Hesitation written across her face.

Nari: Buddy, are you sure you want to move into this house? (She asks, staring at the old structure.)

Hana: Yes. This is the first time I truely know what I want.

Nari: ...Okay then. Let me help you.

In my chaotic life, Nari is the most beautiful gift heaven ever gave me.

She is not just my best friend— she is my safe zone. When rain falls, she becomes the roof that shelters me. A sisterly soul I cherish more than words can ever express.

Nari: Hana, where should I put this box?

Hana: Oh! That one goes in my room. Give it to me. I'll take it upstairs. Can you grab the food instead? It's about to be delivered.

Nari: Yeah, sure. Give me your phone.

Hana: Here you go.

...Huh?

There's another room here.

"Hana... come here, Hana. I'm waiting for you."

My heart stutters.

The voice isn't loud... It doesn't need to be.

It feels familiar in a way that makes my chest ache.

Like something I once knew... Or something that once knew me.

Hana: What's in that room?

Before I can move, Nari's voice cuts through the silence— warm and real.

Nari: Hana, come here. The food's here. Eat first, then we'll do the rest.

Hana: Coming...

My voice sounds steadier than I feel.

I turn away.

But just as I take a step forward, the whisper returns.

"Don't forget me."

That night, sleep refuses to claim me.

The house breathes.

I don't know how else to describe it— every wall creaks like a rib cage expanding, every shadow stretching too long, too deliberate. Moonlight leaks through the curtains, spilling across the floor like pale water.

I sit up. The mirror across my bed catches my movement.

I freeze.

My reflection stares back— same face, same eyes... but something is wrong.

I look tired.

The reflection looks aware.

Slowly, I raise my hand.

It doesn't.

My breath catches in my throat.

The reflection smiles.

Not my smile.

Something sharper. Knowing.

A faint crack appears on the mirror's surface, running straight through my reflected eye.

"You left me here."

The voice comes from everywhere and nowhere.

I stumble back, heart pounding, knocking into the beside table. The mirror flickers, returning to normal. Just glass. Just me.

I press my fingers against my scar.

It burns.

Memories press against the back of my skull— a locked black door, a child crying, hands shaking, and the sound of glass shattering.

I gasp.

The darkness in the corner of the room thickens. And from it, a familiar whisper curls around my name once more—

"This house remembers you, Hana."

I clutch the bedsheet, trembling.

If this house holds my past...

Then the truth I'm searching for may not want to be found.

But it's too late now.

I've already come home.

The nights do not spare me.

Time passes, but not gently.

Nightmares sink into me like roots. Every sleep ends the same way:

Me standing before a black door.

I open it and walk into a dark room. In that room I always end up facing a mirror, my reflection smiling while I scream silently behind the glass.

I wake up every morning drenched in sweat, my heart racing, the echo of whispers still clinging to my ears.

Yet... life goes on.

I learn how to live with it.

I go to college. I laugh when I'm supposed to. I walk beside Nari, pretending the shadows don't follow me.

She talks about classes, assignments, silly dreams. I listen. I always listen.

Nari is soft- too soft for this world. A pure soul untouched by cruelty. And maybe that's why world chooses her.

That day, it happens.

A group of boys block our way near the campus gate. Their laughter is sharp, careless. Words spill from their mouths- mocking, cruel, unnecessary.

Nari stops walking.

Her fingers tighten around my sleeve.

Park Ji-ho: Hey sweety, why so quiet? Cat got your tongue?

Nari: (Nari lowered her head.) I- sorry... We're just going to class.

Cho Seung-min: Going where? (He steps closer. Too close.) At least look when someone's talking to you. He's your senior. Show some respect.

She tries to move back. They move with her.

Nari: Please... excuse us.

That's when I step forward.

Hana: Move.

They turn to me, surprised- then amused.

Park Ji-ho: Wow. You brought a guard dog?

Hana: I said move.

Kim Do-yun laughs and shoves my shoulder.

Kim Do-yun: Relax baby girl. We're just talking.

I push his hand away.

Hana: You're harassing her.

The smile drops from his face.

Kim Do-yun: Watch your fucking mouth.

The first hit comes suddenly. A sharp pain explodes across my cheek. I stagger- but stay standing.

Nari gasps.

Nari: Stop! Please- don't hurt her!

Another shove. Cho Seung-min grabs my arm.

Hana: Don't touch her!

I wrench free, stepping in front of Nari completely now. My heart is pounding so loud I can hear it in my ears.

They hesitate- just for a second.

Then Park Ji-ho scoffs.

Park Ji-ho: You think you're some kind of hero?

Hana: (I wipe the blood from my lip.) No. But you're cowards.

Just then teacher walked toward us and they finally backed off- laughing, muttering insults as they walked away.

Nari's knees buckle the moment they've gone. I catch her before she falls.

Nari: Hana... you're bleeding. I'm so sorry...

Hana: Hey. (I cup her face gently.) You're okay. That's all that matters.

Her eyes fill with tears.

Nari: I couldn't even protect myself.

Hana: (I force a smile.) You don't have to. I'm here.

Nari nods, but her hands are still shaking.

I guide her to a bench near the campus building and sit beside her, keeping my voice low, steady- like if I sound calm enough, the world will listen.

Hana: It's okay. (I tell her.) Breath. Just stay with me.

She wipes her eyes quickly, embarrassed, as if she's the one who did something wrong. I hate that. I hate how this world teaches the gentle to apologize for surviving.

We go to the class together.

I sit closer than usual, my shoulder brushing hers, a silent promise that I won't leave. Nari doesn't speak much the entire day. She stares at the board without seeing it, flinches when someone laughs too loudly.

I notice everything.

I answer questions for her when the professor calls her name. I pass her notes when her hands hesitate. I walk her between classes, never letting more than a step of distance grow between us.

All day, I stay strong.

When evening comes, I walk her home holding her hand. Gently. Carefully. Like the world might hurt her again if I let her go.

At her door she finally looks at me.

Nari: Thank you... for today.

Hana: (I smile.) I told you. I'm here.

I finally let her hand slip from mine and watch as she steps inside. She waves at me while closing the door and I wave back.

Only after the door shuts behind her do I allow my strength to crumble.

The silence presses in.

I turn away and start walking home alone. No one to protect. No one to reassure. No one watching. And this time, there's no one left to pretend for.

My shoulders sag. My breath shakes.

That's when the truth hits me-

Even after everything... I was still too weak. This body is too fragile.

How easily evil walks free. The world doesn't protect the gentle. It feeds on them, rewards the cruel. And cruelty...

Cruelty deserves punishment.

The street is crowded when I head home. Too crowded. People brush past me. Voices overlapping, laughter spilling, footsteps colliding. Life moves loudly all around me.

Yet it feels wrong.

As if the noise is only a shell, and something underneath is holding its breath.

My footsteps echo louder than they should. Not in the street... inside my head.

My thoughts scream over the crowd.

Then I see him.

Park Ji-ho.

Walking ahead of me, phone pressed to his ear, laughing- careless, untouched, alive. The sound of his voice cuts through everything else, sharp and personal.

He doesn't see me.

I stop walking.

People bump into my shoulders, curse under their breath, move on.

The air feels heavier. Thicker. Like the world has narrowed just enough for him and me.

My heartbeat slows- not with fear, but with something colder.

A thought slips into my mind, smooth and poisonous.

"What if he never existed?"

The thought doesn't fade. It echoes. Again. And again. Curling around my ears, sinking deeper with every breath.

Hana: What if he never exists?!

My lips follow the voice. Something inside me... quietly agrees. And it scares me. Deep down, I already know the answer.

I swallow hard, the words lingering in the air like smoke that refuses to clear. Saying them aloud feels like betrayal- of hope, of every quite dreams I've ever folded into my chest and hidden there. Yet the silence after them feels honest. Too honest.

The realization settles slowly- too comfortable. Too right.

As I watch him walk away, I don't notice when my gaze drifts.

The glass door beside the street catches my reflection, fractured by passing bodies and flashing lights.

But it isn't me.

Her smile stretches slow and wide- sharp, eager. Satisfied. Like she's been waiting for my permission and proud I finally understood.

My breath stutters.

When I tear my eyes away and look back at him-

He turns.

For the briefest second, our eyes meet across the moving crowd.

Confusion flickers across his face.

Then-

His body jerks violently, as if something invisible has seized him from the inside. His mouth opens to scream-

But blood spills out instead.

Skin splits. Bones twist.

People are still walking. Still talking. No one notices yet. And then-

He collapses inward. Not falling. Folding. His body vanishes in an instant, swallowed by something unseen. Blood rains onto the pavement, splattering abandoned shoes and staining the ground. His clothes collapse where he stood, empty. The phone slips free and hits the street, clattering loudly. The screen still glows, the call still open. The voice from the other end crackling through the speaker before dissolving into static.

He's gone. No body. No trace of him. Only blood. Too much blood. And his belongings.

The crowd freezes.

A scream tears through the air.

People shout. Someone drops a bag. Someone else runs. Panic spreads like fire.

I can't move. I can't breathe. The world hesitates, as if it's waiting for me to understand what I've just seen.

The shoes remain where his feet should have been. His clothes lie crumpled and empty on the pavement, like an error left unfixed. Blood gathers where a body should have been. Too much for emptiness, too real to deny.

My knees give out and I collapse onto the street, the world tilting violently. Sounds blur. My ears ring. My hands shake so badly I can't feel them.

I turn my head toward the glass.

She's laughing. Soundless. Wild.

My reflection presses her palm against the glass from the other side, eyes glowing with triumph. Like she's been waiting for this moment forever.

Like she's proud of me.

Terror crashes into me all at once.

This wasn't an accident.

Not imagination.

This was a choice.

I force myself up and run.

Through the crowd.

Through the screams.

I don't look back. But I know-

Whatever lives in that mirror is no longer trapped.

It didn't break free.

I let it out.

And it chose me as its door.

I don't remember how I make it home.

My legs move on instinct, carrying me through streets that blur and bend. Every reflection I pass— shop windows, parked cars, puddles on the road— I avoid. I can feel her watching anyway.

By the time I reach the house, my chest hurts from holding my breath.

The door creaks open.

The house welcomes me with silence.

Too quiet.

I lock the door. Check it twice. Then a third time. My hands won't stop shaking. I press my back against the wood and slide down until I'm sitting on the cold floor.

Hana: It wasn't me. (I tell myself.) It couldn't have been.

But the image won't leave— his eyes widening, the sound his body made when it folded, the blood.

I stagger to the bathroom and retch until my throat burns. Nothing comes up. Just air and bile and fear.

When I lift my head, I see it.

The mirror above the sink.

For a moment, it shows only me— pale, trembling, human.

Reflect flickers.

Then my reflection blinks.

I don't.

She tilts her head, studying me with something like curiosity.

"You ran."

She says softly.

Her voice doesn't echo. It doesn't need to. It lives inside my skull.

I step back.

Hana: You're not real. (I whisper.)

She smiles.

Not wide this time.

Gentle.

Almost kind.

"You asked."

She says.

"I answered."

My knees threaten to give out again.

Hana: No. (I shake my head.) I didn't— I just thought—

"Thoughts are door."

She interrupts.

"You opened yours so easily."

The bathroom light flickers. Her eyes darken.

"Do you know how long I waited?"

Images flash behind my eyes— a child crying in the dark, the floor slick with blood, a voice begging to be quiet.

I clutch my head, gasping.

Hana: Stop— please—

She presses her palm against the glass. I feel it— cold, right between my eyes.

"I protected you."

She whispers.

"I punished him."

Her smile fades.

"Isn't that what you wanted?"

I don't answer.

Because somewhere deep inside, beneath the terror and the nausea and the guilt—

Something nods.

The mirror cracks.

Just a hairline fracture, crawling outward like a vein.

I scream and stumble back, slamming into the wall.

When I look again—

I'm alone.

No voice. No smile. No crack.

Just my reflection, breathing as hard as I am.

I don't sleep that night.

Every time I close my eyes, I see blood.

Morning comes anyway.

Classes. Noise. Normality.

Nari is waiting for me at the gate.

She smiles when she sees me, bright and open, as if yesterday never reached her. As if whatever tried to bruise her only washed over her and passed. There is something achingly innocent about her— like the world after a storm, cleaner, greener, pretending nothing was ever broken.

Nari: You look tired. (She says.) Bad dreams again?

I pause.

Then I smile back.

Hana: Yeah. (I say.) Just nightmares.

A boy laughs behind her— too loud, too sudden. The sound scrapes against my skin, wrong in a way I can't explain. For a moment, it feels like a crack in the air, like something ugly trying to slip through.

My fingers curl without my permission.

I don't look at him. I don't need to. All I can think is how easily brightness gets noticed. How easily it gets touched. How easily it gets ruined.

The thought fades as quickly as it comes. I tell myself it means nothing.

And in the dark surface of a nearby window—

My reflection smiles first.
