The Eleven O'Clock Roll Call

Kim Bora was waiting at the convenience store in front of the cram school.

She wore a hooded zip up over her school uniform, and in her hand was a plastic file folder. Several photos were tucked inside the cover, labeled Baekro Academy Building 3 Night Study Attendance Register.

Bora spoke before Seojin could ask her name.

"Kim Bora. I'm the one who reported it."

She didn't shake hands like an adult would. Instead she showed a time written on the back of a convenience store receipt. 22:31. Arrived in front of the academy.

"My friend said she went home every morning. She told her mom that too. But there's no check out record."

Seojin didn't take the file. He asked first.

"Can we disclose your friend's name?"

Bora shook her head.

"Not yet. Her mom doesn't know."

Behind him, Dogyeong adjusted the strap of his camera bag. The camera was off, but the lens cap was already removed.

"What about the academy's name?"

"Do not disclose without the informant's consent."

Seojin said it, and Dogyeong gave a short laugh.

"Not every request for confidentiality is actually protection."

Bora looked at Dogyeong.

"If the academy name gets out, tomorrow it's my classmates who get called in first. Not the director. Us."

Dogyeong put the lens cap back on. His hand moved reluctantly.

Bora spread out the photos. Several names in the attendance register were covered with correction fluid. The direction of the correction fluid differed from photo to photo. Some days it was applied left to right, other days top to bottom.

"Either different people made the corrections, or the same person corrected it in a different direction every day."

Bora didn't say it like she had the answer. She only stated the difference she'd observed.

Seojin didn't change the order of the photos.

"How many students have no check out record?"

"One for certain. Three suspected."

She didn't emphasize the three. She didn't say the name of the one, either.

At the entrance of Baekro Academy hung a banner listing admissions results. Numbers of students accepted into medical schools and the police university ran down it in rows, and below that was a small notice.

No outside visitors during night self study. No movement before signing the check out sheet. Disruption will be treated as infringement on other students' right to study.

It was a less frightening sentence than the notice at Seongansen. Which was exactly why the students could follow it more easily.

The director was waiting at the entrance of Building 3. He straightened his name tag like someone greeting a guest, not someone receiving a complaint.

"The students are in a sensitive period right now. Let's handle complaints quietly, in the counseling room."

Seojin held out her business card.

"I need to check the night study attendance records and the check out signature sheet."

"You're not police."

"A student reported a possible disappearance."

The director looked at Bora. Bora didn't look away.

"Bora, we agreed to discuss your grades tomorrow."

At that, Bora's hand gripped the file tighter. The comment about her grades didn't sound like a threat. It worked better than an actual threat would have.

Doyun checked beside the academy's automatic door. He looked in order at the sensor above the door, the emergency release button, and the small panel showing the scheduled lock time.

"Auto lock at 23:00."

Eunchae spoke over the call.

"The academy's attendance app is linked to parent notifications. If there's no check out signature, the arrival home notification doesn't get sent."

Seojin asked Bora.

"Did your friend's parents receive the notification?"

"Yes. Every day, apparently. But it's not in the check out sheet."

Seojin wrote the app notification time and the blank line in the paper check out sheet in the same column. The two records were treating the same student differently.

A card was posted on the study room door. Not handwritten, but printed on the academy's own form.

If a name is called twice, answer only once.

Leave empty seats empty.

No movement before the check out signature.

Only three lines. The director tried to take the card down. Doyun didn't grab his wrist, just pointed below the card.

"Photo first."

Dogyeong raised the lens. This time he photographed only the door, with no students' faces in frame. Even after taking the photo, he didn't share it right away. He named the file 3-gwan_gyu-chi-card instead of Baekro Academy.

"Is this enough?"

"No sharing before verification."

"I know."

The words were short, but the dissatisfaction remained.

Twenty six students sat inside the study room. The desks were arranged in six rows, and the two seats at the far back right were empty. The empty seats had no bags, no books. But the seating chart didn't even show those slots existed.

Bora pointed at that spot with her finger.

"Until yesterday, that row was one seat shorter."

Seojin didn't take the seating chart off the wall. Removing it would lose its original position. She photographed it and wrote down the direction of the tape. Upper left, new clear tape. Lower right, old yellowed tape.

The students had their workbooks open. A few looked at Seojin's group before quickly lowering their heads. The number of days left until the college entrance exam was written on the blackboard. 83 days.

The director spoke in a low voice.

"If you come in now, it breaks the kids' concentration."

Bora echoed his sentence right back at him.

"A missing check out record has nothing to do with concentration."

The director didn't answer.

Seojin didn't go to the counseling room. Going there would separate the attendance register from the students. She set up a temporary check sheet on the small desk beside the study room door. Location of the original attendance register, location of the check out sheet, who received the app notification, the door's scheduled lock time.

The director set down his pen, his face uncomfortable.

"We don't have that kind of form at our academy."

"So I'm making a temporary one."

"That's the students' personal information."

"Is the possibility that a student went missing also personal information?"

The director looked at Bora again. Again, she didn't look away. Instead, she pulled out one more photo from the file. The date stamped on the corner of the attendance register was different from today's date.

"This is from yesterday, but there's correction fluid on it from today."

Bora's words weren't long. Seojin took the photo and asked.

"Who took this photo?"

"I did."

"Do your friends know?"

"Just one."

"I won't use that student's name right now."

Only then did Bora's shoulders drop a little. The face of a kid who wanted to be a special informant, and the face of one who didn't want to sell out her friend's name, were both there at once.

Dogyeong didn't photograph that moment. But he made a note. Informant not alone. One peer witness. Name withheld.

Eunchae pulled up the academy app screen from the other end of the call.

"Check out notifications are sent in a batch at 23:03. But the server log shows no access record after 23:00."

"Then who sends the notification?"

"It could be scheduled to send automatically. Or the app processes it as a normal return home even without a check out record."

Seojin didn't pick between the two. She only wrote down: mismatch between app notification and paper check out sheet.

At 22:50, the ceiling speaker turned on. Not a live voice, but a recorded supervisor's voice.

"Night self study attendance is beginning."

The students picked up their pens out of habit. The attendance register passed from the front student toward the back. When a name was called, the student answered, and the person next to them marked it.

The first name went by normally.

So did the second, and the third.

Seojin didn't write down every student's name. What mattered was the mismatch.

Doyun held up two fingers by the door. A countdown to the lock. Seojin only nodded. If they stopped the roll call, the students would scatter. If they let it continue, one more name might get called. She left the recorded voice on and taped a blank sheet of paper beside the attendance register.

Bora was watching the direction the register passed. From front row to back, right to left. The opposite of the correction fluid direction in the photos. She started to point out the difference, then stopped, and drew an arrow on the back of her own hand.

"Why write it on your hand?"

Dogyeong asked, low.

"Because they collect the paper."

Bora's answer was short. She didn't look like a frightened student. Instead, like someone who'd been scolded plenty of times before, she already knew where to keep a record that couldn't be taken away.

Seojin didn't photograph the hand. Only after Bora drew the same arrow on the file did she record it as a photo.

At the fourteenth name, the speaker said,

"Lee Juho."

That name wasn't in the attendance register.

A boy in the second seat of the left row answered out of habit.

"Here."

The answer came too fast. The speed of someone who thought they'd been called.

Bora immediately opened the register. There was no name Lee Juho in it. The boy's real name was Park Minjae. His name was also written as Park Minjae on the workbook on his desk.

One student said quietly.

"Juho didn't come today though."

The student next to him asked right away.

"Who's Lee Juho?"

Memories collided against each other. One spoke as if about a classmate, the other asked back as if hearing the name for the first time. Park Minjae set down his pen like someone realizing late that he was the one who'd answered.

Seojin didn't blame him.

"If your name is called a second time, don't answer."

The director cut in.

"Don't scare the kids."

Seojin didn't look at him. She drew a new box in the margin of the attendance register. No name. Respondent Park Minjae. Witnesses Kim Bora, Yun Seojin.

Bora wrote the time next to her own name. 22:53.

At that moment, Park Minjae's desk shifted one space sideways.

The sound was small, just the scrape of chair legs on the floor. But the students all lifted their heads at once. Park Minjae hadn't pushed it. His knees were still where they had been, under the desk.

A new space appeared at the empty back right seat. A faint square, not yet on the seating chart, showed up. A white outline, like correction fluid not yet dry.

Doyun moved toward the automatic door.

"Seven minutes to lock."

Eunchae said.

"Park Minjae is showing up twice on the attendance app. One entered, one not checked out."

Seojin didn't explain. She asked Park Minjae.

"Can you stand up from your seat right now?"

Park Minjae tried to stand. The chair pushed back, but his feet didn't move toward the door. His movement cut off, as if caught between the desk legs.

Bora immediately tried to go toward the empty seat. Seojin raised her hand.

"Leave the empty seat empty."

Bora stopped. Only after stopping did she notice her foot had been about to step on the line of the blank square.

The director spoke toward the students.

"Everyone, back to your problems. This is an outside disturbance."

A few picked their pens back up. Words like grade report, contacting parents, and right to study seated the students faster than the door lock did.

Seojin recorded the director's words. Directive to treat as outside disturbance. Students kept seated.

23:00 arrived.

The check out signature sheet was placed on the podium. Students tried to line up, but the automatic door locked first. The locking sound was lighter than a subway door's. Which was exactly why it registered as danger a moment too late.

A few students called their parents right away. The calls connected, but on their phone screens, the arrival home notification already showed as sent.

Mom, I'm still at the academy.

One student's sentence cut off partway through, at the front of the study room. What the other side said couldn't be heard, but the student couldn't explain any further. When the arrival notification reaches a parent before the child's own words do, those words end up sounding like an excuse.

The director told the students to put their phones down.

"Don't make the parents anxious."

Bora asked again.

"Anxiety isn't the problem here. The notification is wrong."

She repeated the director's own phrasing back at him without raising her voice. Seojin looked at where Bora was standing. She was two steps from the empty seat, and far from the door too. She hadn't rushed in to fix it herself.

Seojin didn't write her own name on the first line of the check out sheet. There was no telling how the safety rules would read an outsider's name entered into a student record. Instead, she made a separate outside witness column on a sheet beside the check out sheet.

Yun Seojin, Kang Doyun, Yi Dogyeong, Kim Bora.

Bora started to write student next to her own name, then stopped. Without Seojin saying anything, she crossed it out and wrote informant instead.

The director tried to take the sheet away.

"You can't write a minor's name on an outside document."

Bora pulled the sheet back toward herself.

"I wrote my own name."

Seojin set her pen down between the director's hand and the paper. Not to block him, it ended up shaped like a space made for a signature instead.

"This is the access restriction consent line. You should sign it too, director."

The director didn't pick up the pen. In the meantime, the automatic door's lock light changed from green to yellow.

Only Park Minjae stopped at the threshold. The other students could reach the door, it just wouldn't open. Park Minjae couldn't even reach the threshold.

A name appeared in the empty box of the attendance register.

Park Minjae.

Beneath it, the same name was written once more.

Park Minjae.

Bora bit her lip but didn't cry. Instead, she took a photo. Her hand shook a little, but the two lines of the name were visible.

"It's written twice."

Seojin nodded.

"He answered once, but it was recorded twice."

The ceiling speaker turned on again.

"Beginning re-attendance."

The first name was called. None of the students answered. Just as the director was about to tell them to answer, Park Minjae's voice came from the direction of the empty seat at the back.

"Here."

Park Minjae was standing in the front row. He hadn't opened his mouth.

No one was sitting in the empty seat yet.
