Chapter 21 — Theater at the End of the Hallway

The rooftop scene took place at four o'clock in the afternoon. They want to record the entire view of building B and the routes students pass through. Teacher Quang allowed five people to board, but Quan brought six chairs, causing the group to go back and put them away.

“The chair also needs a view of the city,” Quan said.

“The chair does not have a consent form,” Tran replied.

On the rooftop, the wind blew strongly. Vy placed the recorder in the corner of the wall, using tape to secure it. Lam turned his feet to walk across the yard, not turning away without asking. Huy stood next to the railing, checking the projector signal with Dat below.

They discovered from above that the theater's roof had a window painted black. Next to it is a star-shaped line. Mr. Quang said it was an old ventilation door, once closed when a camera fell down.

Lam asked her mother about the window. Hoai An said the last scene had light from above, but couldn't remember which door. She thinks Khai chose the rooftop because Nhi wanted to see the sky before stepping out.

Dat found the key to the ventilation door. They don't open right away; Ms. Thao requested a safety check. Huy used a small camera to pass through the slot and saw a metal box lying on the beam. Quan wanted to climb but everyone unanimously refused.

“I'm just a person with an exploratory spirit.”

“You're the one who just broke three chairs,” Tran said.

Maintenance staff took down the box. Inside is a flashlight, a roll of green string and Dat's small notebook when he was a student. He read a few pages and saw that he had written: "If the theater is locked, turn on the lights from the rooftop to let people in the hallway know that there are still people who remember."

“I forgot this,” Dat said.

“But the projector doesn't forget,” Quan replied.

Lam filmed the members on the rooftop. Hoai An was invited to stand in the frame, but she shook her head. Dat also stood outside. Huy himself put his hand into the sunlight, creating a distorted image on the wall.

Vy recorded the sound of the wind and the school bell. She said the sound upstairs was different from down the hallway: wider, but also lonelier.

When the sun went down, Lam asked each person a question: "What do you want to keep in the theater?"

Tran: “The right to try and do it again.”

Quan: “A chair that doesn't collapse.”

Vy: "Other people's voices can be heard without being drowned out."

Huy was silent for a long time. Finally he said: "A place that doesn't force you to appear the way others want you to."

Lam did not ask further. The answer will be in the movie if Huy allows it. He nodded, agreeing to use the sound but not the face.

That night, they watched the rooftop scene again. One frame is blown out, revealing the shadow of a black window and a piece of writing on the wall: **A →**. The arrow points to the theater area, not the train station.

Mr. Quang realized that this symbol was once used to indicate an emergency exit. It leads to a small room behind the curtain, which the group has not opened because they thought the walls were solid.

Tomorrow, they will check. The countdown has one day left. Lam felt both nervous and calm; they are no longer trying to find a lost scene. They're looking for a way for latecomers to film their own scenes.

On the rooftop, the group divided tasks according to each hour. Huy checks the wires first, Vy records later, Lam shoots when everyone agrees. Tran stood at the door, recording people going up and down. Quan was assigned to carry water, but he dropped a bottle down the stairs and had to pick it up.

The sun goes down slowly. The campus from above looks like an unfilmed movie: the football field has dots of white shirts, the hallways are straight lines, the tent roof is a dark patch between the phoenix trees. Lam wanted to film the whole scene, but Huy reminded him not to turn the classroom window if there were students.

“The frame is more beautiful if there are people,” Lam said.

“People are not accessories.”

Lam hung up the phone. She found herself learning to look without taking up space.

Duc Minh discovered a green rope tied to the railing. The wire runs down to the roof of the theater, the other end is hidden in the drainage pipe. Huy did not pull; he called Mr. Quang. Maintenance staff checked and found a small light pointing at the ventilation opening.

Dat realized that this lamp had been used in a test projection system. He signed the release note and did not handle it himself. Tran wrote down the device number, and Lam asked the employee if he wanted to be reminded by name. The person shook his head, just wanting the work to be recorded correctly.

When the lights turned off, a small streak of light appeared on the theater screen. Vy recorded the sound of the switch, but did not use it immediately. She said she needed to listen to the audio circuit to know if it would mislead viewers.

The group tried projecting the door shadow from the terrace. Huy held the phone, Lam stood in the open position. Her shadow stretched across the wall, her face could not be seen. Quan walked in, making the ball swell, the whole group laughed. Tran asked if she could keep her laughter; Quan agreed.

Hoai An watched the recording via controlled live video. Mom said this light is not like the old scene, and that's a good thing. Lam asked her mother if she was afraid that viewers would compare her. Mom replied that if the comparison helps them understand that the new scene was done with consent, then it's okay.

Strong wind causes a reflector to fly. Huy ran after him and slipped, but Dat was able to hold his shirt. Quan wanted to film the moment, Huy said no. Military put away the phone immediately.

Once safe, Huy thanked Dat. Dat said he only kept his sleeve, not saving anyone. Huy said sometimes holding on to one sleeve is enough to make someone stop.

Lam wrote that sentence in his notebook but asked Dat if he could use it. He said it would be okay if he wrote his name. Each word becomes a small exchange, no longer something the group takes for itself.

When leaving the terrace, Lam looked at arrow A. It pointed down to the theater, but it no longer looked like a challenge. It's like a marked path so people don't have to guess.

Tran asked each person to record one task that could be handed over to the junior class. Huy wrote down how to listen to the sound of the fan, Vy wrote down how to ask permission from the person sending the sound, Quan wrote down how to arrange chairs so they don't block the way, Lam wrote down how to ask again before using. The pages are placed next to the terrace map.

Dat read and said a plan only lives when the next person understands why it exists. He suggested adding a historical part, but Hoai An reminded him not to include Nhi's personal details. They wrote a common line: "There was a story once kept to protect a student; every generation must continue to question the teller."

Huy closed the light box and signed the inspector's name. Lam stood at the door, watching the last light of the day fall on the tile floor. She didn't film, but clearly remembered the sound of Quan pulling out a chair and Vy taking off the camera.

The night before the meeting, the group tries to walk through the entire process as a new audience. The instruction board is located a bit high, they lowered it to eye level. The exit was blocked by a box of posters, Tran moved it aside. Quan saw that the curtain covered the "toilet" sign, so he tied a red ribbon as a sign. Huy checked the emergency lights, and Vy opened the subtitles on the tablet.

Lam sat in the shaky chair he had just fixed, looking at the screen from the most hidden corner. A power line runs at foot level. She called Huy, not pulling him arbitrarily. They fixed the wire with a brace and posted a warning sticker. Those changes do not appear in the trailer, but makes tomorrow's screening safer. Before locking the door, Lam read out the list: electricity, walkways, sound, image rights, drinking water. Quan asked why there was no "cookies" section. Pearl added to the end of the list. The whole group laughed, then signed each person's name.

On the morning of the screening, Lam arrived early and saw a notice taped to the door: "I don't want to be filmed, but want to help arrange chairs." She didn't know who wrote it, so she put the paper in the suggestion box and opened the door to let everyone in. One person took it upon himself to arrange the chairs according to the diagram, one person cleaned the handrails, and one person checked the large board. No one is asked their name if they don't need to. Huy gave him gloves and reminded him not to move the chair marked for inspection.

When the first customer walked in, Quan discovered that the seat number on the ticket was the same. He didn't blame the printer; He apologized, changed seats and wrote down the reason. Please edit the ticket form immediately, add the area code. Lam realized a successful show is not about being error-free, but rather about errors being recognized before embarrassing someone. She looked at the "you can just sit" sign and then stepped aside, letting others find their own seats.

When the movie started, the projector made an unusual noise. Huy did not panic; he informed the audience, paused and called the technician on duty. Some people suggested continuing because the sound also has its own characteristics, but Huy explained that hot equipment can be dangerous. The whole room agreed to take a ten-minute break. Quan handed out cookies, Tran opened the door for fresh air, Vy kept the screen waiting.

The technician replaces the filter, records the time, and instructs the team to recognize unusual humming sounds. Huy asked if he wanted to appear in the credits. He just wanted to write down the name of the maintenance unit. Lam added his name properly, did not film his hand without permission. As the screening continued, the audience applauded for the timely stop. Quan said this was the first time he saw an audience clapping because a machine was not running. Lam replied that they clapped because everyone took care of each other.

The team then updates the maintenance schedule right on the door panel, so viewers know the machine has just been inspected and when the next time is.
