Minh woke to the smell of smoke.
Not smoke from the explosion. That smell had thinned, driven out of the underground room by rainwater and wind. This was old smoke, clinging to his hair, his clothes, and the cracks in the rotting walls.
He opened his eyes.
Lan was sitting on the edge of the bed.
Their rented room was lit only by a flashlight on the floor. A basin caught the leaks beneath the corrugated-metal roof. The old fan sat silent. On the table, two bowls of cold noodles rested side by side, one untouched.
Minh raised a hand to his forehead.
“Where’s the plant?”
“We made it out.”
“Hung?”
Lan didn’t answer.
She looked down at her wrist. The white scar lay beneath the flashlight beam, so clear that Minh felt as if it had just appeared.
“He made it out too.”
“Then where is he?”
“He left.”
“Disappeared again?”
Lan slowly closed her eyes.
Minh sat up. Pain shot from the back of his neck to the crown of his head. For a moment, he saw the concrete floor shaking, Hung dragging him through a smoke-filled corridor, Lan clutching the blue cloth bag tightly against her chest.
Then another image pushed its way in.
A man lay beside the valve wheel.
Not Hung.
The man wore a factory uniform. One hand clutched his chest, while the other still gripped a gas can. His face was hidden by the flames, but his voice was perfectly clear:
“Minh, you promised.”
Minh sprang to his feet.
“Who is the fourth person?”
Lan looked at him.
“I don’t know.”
“You do.”
“No.”
“You know everything.”
Minh’s voice wasn’t loud, but it made the room feel smaller. He looked at the table, the two bowls of noodles, the dented pot beside the gas stove. The things they had used to survive ten years suddenly became evidence against them: every object concealed a pocket of silence beneath it.
Lan stood.
“You need to rest.”
“I’ve rested for ten years.”
She froze.
Minh lifted his phone. Its screen had cracked in the explosion. There were no new messages. Only one old line remained:
“The disaster didn’t begin at 9:40 p.m.”
“What did you do to my memory?”
Lan turned away.
Outside the door, a motorbike passed, its engine fading at the end of the alley.
“I didn’t do anything.”
“Then why did Hung say you made me forget?”
“Because he wants you to hate me.”
“And what do you want me to do?”
Lan didn’t answer.
Minh stepped down from the bed. His feet touched the cold cement floor. He walked to the wooden cabinet against the wall, where Lan always kept their papers, rent money, and neatly folded bills.
Lan immediately blocked the cabinet.
“Don’t open it.”
Minh looked at her.
“What’s in there?”
“Things you shouldn’t see.”
“That’s the only thing you’ve ever said to me your whole life.”
“Because I want you to live.”
“No. You want me to live as someone else.”
Lan began to tremble.
Minh didn’t pull her aside. He simply stood there and waited. That was how he had handled everything in their marriage: ask no more questions, make no one uncomfortable, take on the heaviest burden, and tell himself tomorrow would be easier.
But tomorrow had arrived ten years ago.
Lan slowly stepped aside.
In the bottom drawer was a small metal box. Its lock was rusted. Minh recognized the blue H-shaped paint mark on the lid.
He opened it.
Inside was an audio cassette, a crumpled sheet of paper, and a silver ring that didn’t fit his finger.
The paper held only one sentence, written in Minh’s handwriting:
“If you ask again, don’t answer for yourself.”
After reading it, Minh looked up.
“This is my handwriting.”
“I know.”
“When did I write it?”
“After that night.”
“Why did you hide it?”
Lan sat down on the plastic chair beside the stove. She placed both hands on her knees. She looked so small that Minh suddenly remembered the early days they had lived together in a room even smaller than this one, when Lan had covered the hole in the window with an old cloth and laughed because the two of them had only had enough money to buy half a kilo of rice.
“Do you want to hear the truth?” she asked.
“I’ve been waiting ten years for it.”
“No. You’ve been waiting for a story that would let you keep loving me.”
Minh said nothing.
Lan placed the cassette in the old player.
Static came first. Then rain. Metal clanging against metal. A younger, frantic version of Minh’s voice:
“Lan, give me the bag.”
“No.”
“You don’t understand where this is going.”
“You’re the one who doesn’t understand.”
A heavy thud.
Hung’s voice rang out in the distance:
“Minh, put down the gas can!”
Present-day Minh clenched his fists.
On the recording, his own voice began to laugh. It was a hoarse, cold, unfamiliar laugh.
“Too late.”
Lan burst into tears.
“What did I do?” Minh asked.
She didn’t answer right away. The tape kept playing.
Footsteps raced across the concrete floor. Glass shattered. Then Minh said, very softly:
“If we don’t burn this place down, we’ll all die.”
Hung shouted:
“There’s someone in the tank!”
A stretch of silence.
Then came the roar of flames.
Minh stumbled backward. An image surfaced with painful clarity: the control room door was locked. Inside, a man pounded his hands against the glass. Hung was trying to break the door down. Lan was pulling Minh toward the exit.
And Minh stood in front of the electrical panel.
A ring of keys was in his hand.
“No…”
“That man was my father,” Lan said.
Minh looked at her.
“My father worked at the plant. He discovered that the pipework had been illegally altered, but they wanted to frame him. He planned to take the documents outside. That night, he locked himself in the control room to preserve the data.”
“You locked the door?”
“No.”
Lan wiped away her tears.
“You took his keys.”
“What for?”
“To open the sluice gate.”
She pointed to the silver ring in the box.
“He gave it to you. He told you to run while he held back the fire. But you turned back. You wanted to save him. Then you saw the documents.”
Minh looked down at the cassette.
“What was in the documents?”
“The name of the person who hired my father to alter the pipework. The name of the person who set the fire. And your name.”
The room sank into silence.
Minh heard the sound of his own breathing.
“I don’t understand.”
“You had signed a false report before that. You didn’t know you were being used. But your signature was in the documents.”
“So I killed your father to cover it up?”
Lan shook her head, tears falling onto the back of her hand.
“You didn’t kill him.”
“But I let him die.”
“You saved Hung.”
Minh looked at her.
Lan continued, each word seeming to be dragged from her throat:
“You chose to open the sluice gate. The chemical water flooded into the old sewer system and put out the fire in the residential area. But to open it, you had to abandon the control room. My father was still inside.”
“And Hung?”
“Hung went back to save him. You dragged Hung out.”
“Why?”
“Because he was burned. Because he was about to pass out. Because at that moment, you could only save one person.”
Minh raised a hand to his head. The pain pounded through him again.
A distorted memory burst free.
Lan was holding him in the rain. Hung knelt beside them, his face covered in blood. Behind them, the plant burned red. Minh held the silver ring, repeating the same words over and over:
“I don’t remember. I don’t remember anything.”
A younger Lan pressed her hand to his cheek.
“Then don’t remember.”
“Did you hypnotize me?”
“No.”
“What did you do?”
Lan looked straight at him.
“I told you a different version. A little at a time, every day. That night, my father died in an accident. Hung disappeared because he ran away. You were injured, so you forgot a lot. We got married the next day.”
“You lied to me for ten years.”
“Yes.”
Her unresisting answer hurt Minh more than any excuse could have.
“Why?”
Lan looked at the wedding ring on her finger.
“Because after that night, you woke up and asked me one question.”
“What question?”
“You asked, ‘Am I still a good person?’”
Lan smiled faintly, her smile shattered.
“I couldn’t answer. I only knew that if you remembered, you would condemn yourself before anyone else had the chance to say anything. I wanted you to have a different life. A small room. A poor job. An anniversary to look forward to.”
“And in that life, you were going to kill me?”
Lan’s head snapped up.
“What did Hung tell you?”
Minh’s phone vibrated.
A new message appeared:
“She told you exactly half the story.”
Minh and Lan both stared at the screen.
A second message arrived immediately after:
“The man in the control room didn’t die in the fire.”
Lan went pale.
A third message:
“He lived for another sixteen hours.”
Minh looked up.
“Your father survived the fire?”
Lan said nothing.
Outside the room, a key slid into the lock.
A man’s voice came from behind the door:
“Lan, open the door.”
She shot to her feet.
Minh looked at her.
“Who is it?”
Lan backed toward the stove, her face deathly pale.
“My father.”
The door shuddered beneath a blow.
The man outside spoke in a low, calm voice:
“You’ve hidden it long enough.”
Minh looked back at his phone. The screen lit up one last time:
“Don’t let him see Minh before Minh remembers who was holding the gas can.”
The second blow knocked the lock out of the door frame.
Lan snatched up the kitchen knife.
And for the first time, Minh saw in her eyes not the fear of a wife cornered with nowhere to run.
But the look of someone who had been preparing to kill someone for a very long time.
