The Last Green Dot

Serim Villa 301 was less a building than an emptied shell.

By the time Ji-an arrived it was a little past six in the morning, yet inside it felt quieter than night. The glass front door was cracked. The stairwell bulbs flickered once on the third floor and once again in front of the narrow iron door leading to the roof. There was no smell of people living there anymore, only damp dust.

Rooftop greenhouse, 301.

Without Su-bin's note, Ji-an would never have imagined that any sort of greenhouse still survived on top of this near-abandoned building.

When she pushed the iron door open, the smell of wet soil rushed out at her. Greenhouse was too grand a word. The transparent vinyl walls were torn in places, half the pots held nothing but dry stems, and several planters had toppled over completely. Still, one corner showed traces of recent hands: less dust, a neatly moved water container, a small steel storage box on the floor.

Ji-an stood in front of it for a long moment.

All through the previous night, fury and fear had pushed her forward. But faced with the last place, those feelings thinned and something else flooded in first: exhaustion. Three days since Su-bin died. The funeral, sorting belongings, the phone booth, the locker, the roster, the threatening messages. Too many emotions had passed through her body in too little time. Even the damp air in the greenhouse felt unreal.

The steel box was not locked.

Inside sat a portable recorder, a black USB-like memory stick, a half-charged power bank, and one folded sheet of paper.

On the paper was a name and phone number.

Eun-seo.

Nothing else. No surname, no explanation. As if Su-bin had believed that this single name would be enough.

Ji-an picked up the recorder first. Its display listed only one file.

47D-LAST.

She pressed play with trembling fingers.

At first there was only breathing. Rough, shallow breathing. Wind passing the microphone. The squeal of brakes somewhere in the distance. Su-bin sounded as if she had been running, or had only just stopped.

Then the familiar voice came.

Unni. If you're hearing this, then it means you ended up going exactly where I was most afraid you'd have to go.

Ji-an closed her eyes.

This voice was different from the prepared recording in the phone booth. That one had been clean and controlled. This one shook with breath and broke at the ends of sentences. It was not a message from a dead girl shaped into a system. It was a living person at the edge of time.

I'm sorry. This really is me handing it over to you.

She could hear Su-bin swallow air.

At first it started because of Mom. I thought GachiSum was really for safety. Then I saw the admin panel and couldn't stop. Eun-seo, Grandmother Jeong-ae, the women living around here—they all installed it to protect their own locations. And all of it was being sold.

Ji-an's hand tightened around the recorder.

I thought I could just gather proof and get out. But my location was already in their hands too. So I split everything up. The phone booth, the locker, the rooftop. Because if anyone followed it to the end, it would be you. Because there wasn't anybody else.

The moment she heard that, Ji-an lost even the strength to be angry. Su-bin had believed in her to the end, and at the same time spent herself trying to keep Ji-an out. Both truths still clung to her voice.

If I came back alive, good. I know. But that's not going to happen.

Ji-an held herself perfectly still.

So unni, don't keep following my location after this. Coming here is enough. Call Eun-seo first. Don't hold the files alone. Send them to at least two places. And...

The voice stopped. In the background, very faintly, came the sound of someone running.

If anyone says my death was just an accident, don't believe it.

Ji-an went rigid.

Su-bin kept speaking as if cutting the remaining time into pieces.

I left the location share alive so you'd come. We still had Mom's family permission active, and somebody told me that if it stayed on, you'd get one signal within forty-nine days. I believed it. Not because I was scared. Because I believed you'd stand on the side of the people still alive.

Then the last words came, barely above breath.

This time, don't protect my location. Protect the locations of the people who remain.

The file ended there.

Ji-an did not lower the recorder for a long while. Wind slid through the torn vinyl walls, scratching at dry leaves. Far away, scooters and early delivery bikes began to move. The world was resuming its morning. She alone felt pinned beneath one sentence.

Don't keep following my location.

Even after death, Su-bin was still pushing her forward.

Ji-an wiped once at the corner of her eye with the back of her hand. The tears did not come as easily as she expected. Instead something firm began to gather under the grief, a direction hardening inside her.

She checked the memory stick. Two compressed files and three video clips. One was a screen capture of the GachiSum admin panel. Another showed a meeting inside the Dongmun field office. The faces and name tags were not perfectly clear, but enough aligned with the names in the paper notes that several people could already be identified. The final video shook violently and cut off with someone approaching Su-bin in a night alley.

It was not complete proof in the legal sense. But it was far too much to dismiss as nothing.

The next problem was who to give it to.

Ji-an looked at the number written under Eun-seo's name. Even before pressing call, she hesitated. What if it had already been changed? What if Su-bin had left it as bait? But in the final recording, Su-bin had named Eun-seo first.

The line rang three times.

...Hello.

Ji-an said nothing at first. The woman on the other end inhaled sharply.

Are you... Su-bin's unni?

Ji-an felt her mouth go dry.

Are you Eun-seo?

The woman did not answer immediately. Ji-an heard the sound of a door being locked.

Did Su-bin really make it to you?

That was enough. Eun-seo belonged to the same side Su-bin had been protecting.

Ji-an gave the shortest version she could: the phone booth, the locker, the rooftop, the recorder. Eun-seo grasped it with frightening speed.

Upload the files from where you are. Cloud and email, both. And before the press, send them to the women's legal support lawyer. Did you see the little star marked next to the number Su-bin wrote? That means lawyer.

Ji-an unfolded the paper again. There it was, a tiny penciled star she had mistaken for a smudge.

And one more thing, Eun-seo said. The day Su-bin died wasn't just a slip-and-fall accident. Someone was chasing her. I saw it. I was too scared to come forward right away. But she said she'd leave something for her sister at least.

Ji-an gripped the greenhouse railing. The cold iron bit into her palm.

This was no longer only intuition. Su-bin had been pursued. She had died within that pursuit. Her death could not be left under the word accident.

Ji-an connected the memory stick to her phone and began copying the files. One went to her cloud drive, one to the email Eun-seo gave her, and the last to the lawyer's address marked with the star. Even while the transfer bar crept forward, her fingers kept shaking.

Then another message arrived on her main phone.

Final warning.

This time Ji-an did not linger on it. She screenshot it immediately and sent it to Eun-seo.

I'll send the number too.

Now you're not alone, Eun-seo replied.

That one line steadied Ji-an more than she expected.

Outside the greenhouse the morning grew clearer. The surfaces of the city, soaked through the night, were slowly reclaiming color. Light slipped through the torn plastic and struck the recorder screen.

Ji-an switched on the backup phone one last time. The green dot was still there, but no longer as a moving life-sign. It felt more like the residue of one last permission.

The line that used to say time until next share was gone. In its place there were only two choices:

Keep sharing.
End sharing.

She did not know whether Su-bin had truly calculated even this, or whether it was simply a leftover behavior in the app. The meaning, however, was unmistakable.

Ji-an could continue holding on to her dead sister's location for a little longer. Another few days, another few hours, however long her heart demanded. It would let her keep the illusion that Su-bin was still guiding her from somewhere.

But Su-bin had said it clearly:

This time, protect the people who remain.

Ji-an moved her thumb to End sharing.

A confirmation prompt appeared.

End location sharing?

She did not hesitate.

Yes.

The green dot vanished.

The world did not truly grow quieter. Below the villa she could still hear the slam of a delivery truck, a distant school announcement, the scattered noises of a neighborhood waking up. But something inside Ji-an finally cut loose.

It was not the end.

It was closer to a beginning.

Following Su-bin was over. What remained now was carrying what Su-bin had left toward the living: Eun-seo. Grandmother Jeong-ae. The unnamed others whose lives had been exposed through an app they had trusted.

Ji-an packed the recorder and memory stick into her bag and closed the greenhouse door behind her. Sunlight was filtering into the stairwell windows now, catching dust in long pale beams. The cold that had held her all night did not disappear completely, but it no longer had the same shape. There was direction inside it.

On the third-floor landing she sent one short message to Eun-seo.

I sent everything. Let's stay in this to the end.

The reply came almost at once.

It's what Su-bin would've wanted.

Ji-an stopped and looked at the screen. For the first time since the funeral, she read Su-bin's name without thinking first that she had to get her back.

Instead she thought of the people Su-bin had refused to abandon.

The dead girl's location was gone.

But the place it had occupied was not empty. It had become, instead, the coordinates of what Ji-an now had to protect.
