FLASHBACK — ORIGINAL TIMELINE
DAY 15 OF THE FIRST FREEZE
The cold was worse back then.
Not in temperature — in people.
The first freeze had stripped away civilization's mask in seventy-two hours. By day fifteen, the building had become a tomb where the living preyed on the weak, and the strong pretended they weren't already dead.
Jae-Min remembered it clearly.
Because that version of him was weaker. Slower. Unprepared.
I. THE STARVING MAN
His apartment was a frozen coffin.
The windows had cracked from thermal stress, letting in knives of cold that no amount of improvised sealing could stop. His breath crystallized in the air, falling like snow onto the carpet.
Three days without food.
Water almost gone.
The last candle had burned out hours ago.
Jae-Min sat in the darkness, wrapped in every piece of clothing he owned. His stomach had stopped growling two days ago. Now it just ached — a hollow, gnawing emptiness that consumed him from the inside.
"Fuck..."
The word came out as a whisper. His throat was too dry for anything louder.
He wasn't surviving.
He was fading.
II. THE KNOCK
Knock.
Soft. Careful.
Not the desperate pounding of people begging for help. Not the violent kicking of those trying to break in.
Just... knocking.
Jae-Min didn't move.
In those days, opening doors meant death. He'd watched his neighbor get dragged into the hallway three days ago. Watched them tear him apart for a can of beans.
The knock came again.
Gentle. Patient.
"...hello?"
A woman's voice. Calm despite the cold.
"I'm not here to hurt you."
Silence.
Jae-Min's hand moved toward the kitchen knife on the floor beside him. His fingers closed around the handle. Weak. Trembling.
"...please. I'm a doctor. I just want to help."
A doctor.
Useless, some part of him thought. What good is a doctor when the world is already dead?
But something in her voice made him hesitate.
III. THE FIRST MEETING
The door opened.
She stood in the corridor, wrapped in layers of improvised insulation — blankets, towels, plastic sheeting. Her face was pale, lips cracked from cold, but her eyes were clear. Focused.
Behind her, the hallway stretched into frozen darkness. Bodies lined the walls — neighbors who had frozen, starved, or been killed. She stepped over them like they were furniture.
"You look like you haven't eaten."
Not judgment. Observation.
Jae-Min stared at her from the doorway. He knew he must look pathetic — skeletal, shivering, one hand still gripping the knife.
"What do you want?"
"Nothing." She reached into her bag. "I'm checking on survivors. Treating what I can."
She pulled out a small ration pack. Military grade — the kind that lasted years in storage.
"Take it."
Jae-Min stared at the food.
His brain couldn't process it. Someone was giving him something? In this world?
"Why?"
The question came out hoarse. Suspicious.
A pause.
Then —
"Because you need it more than I do."
IV. THE GIFT
He took the ration.
Hands shaking so badly he almost dropped it.
He tore it open. Didn't bother with the heating element — just shoved the cold food into his mouth. Chewing. Swallowing. Desperate.
"Slow down." Her voice was gentle. "You'll make yourself sick."
But hunger didn't listen.
He ate until the pack was empty. Then licked the wrapper. Then stared at her.
"Why are you doing this?"
"Because someone has to."
"That's not an answer."
"No." She almost smiled. "It's not."
V. THE DOCTOR'S ROUTINE
She came back.
The next day. And the next. And the next.
Always checking. Always treating. Always giving.
Jae-Min watched her work through his cracked door. Watched her move from unit to unit, helping people who had nothing to offer in return. Treating frostbite. Setting bones. Stitching wounds with thread she'd salvaged from curtains.
Sometimes she received food in exchange. Sometimes nothing.
She never complained.
"This won't last," she said one evening, sitting in his doorway. "The cold. The isolation. The government will stabilize things. Aid will come. We just need to hold on."
Hope.
Still alive in her.
Jae-Min said nothing.
Because even then — even in those early days — he knew the truth.
No one is coming.
VI. THE DECLINE
But the world didn't recover.
It worsened.
The temperature dropped further. Resources vanished. The people she'd helped began to turn — not because they were evil, but because hunger didn't allow morality.
She started coming less often.
Her visits grew shorter. Her movements slower. The light in her eyes dimming.
One day, she arrived without her bag.
"Where's your supplies?"
"Gave them away."
"All of them?"
"People needed them."
He stared at her.
"You need them too."
"I'll manage."
She always said that.
I'll manage.
VII. THE LAST VISIT
Day 31
She knocked on his door.
The sound was weaker now. Barely audible.
When he opened it, he barely recognized her.
Her cheekbones jutted sharply beneath papery skin. Her eyes had sunk into hollow sockets. Her lips were cracked and bleeding. She'd lost weight — dangerous amounts of it.
But she was still smiling.
"You're alive."
Jae-Min frowned.
"You look like shit."
A faint chuckle. The sound rattled in her chest.
"Occupational hazard."
She reached into her pocket.
Pulled out a single ration bar. Smaller than before. The last one.
"Take it."
He didn't move.
"What about you?"
A pause.
"I'll manage."
Lie.
Obvious, transparent lie.
But she said it anyway. With that same quiet smile. That same stubborn hope.
He took the bar.
"Thank you."
"Don't mention it."
She turned to leave.
Then stopped.
"You know..." Her voice was soft. Distant. "I think things will get better. They have to."
She walked away.
And Jae-Min never saw her again.
VIII. THE SEARCH
Day 41
Ten days.
Ten days since her last visit. Ten days of waiting. Ten days of wondering.
By now, Jae-Min had grown stronger. The food she'd given him had kept him alive long enough to scavenge. Long enough to find his own supplies.
Long enough to search.
He found her on the 7th floor.
Unit 704.
The door was unlocked. He pushed it open.
IX. THE BODY
She sat against the wall.
Positioned carefully, deliberately — as if she'd known the end was coming and wanted to meet it with dignity.
Her eyes were closed.
Her expression was peaceful.
No wounds. No blood. No signs of violence.
She hadn't been killed.
She had starved.
Her bag lay beside her. Empty. Completely empty. Not even crumbs.
The final irony hit him like a punch to the chest:
She'd given everything away.
Every ration. Every bandage. Every ounce of supplies.
Until there was nothing left for herself.
X. THE FUNERAL
He couldn't bury her.
The ground was frozen solid. The corridors were too dangerous.
So he did the only thing he could.
He wrapped her in blankets. Arranged her hands across her chest. Closed her eyes more gently.
"Dr. Alessia Romano Santos."
He spoke the words into the frozen air.
"Chief of Emergency Medicine. St. Luke's Medical Center."
His voice cracked.
"You saved people. Even when you had nothing left to give."
He stayed with her for an hour.
Then closed the door and never returned to that floor.
XI. THE MEMORY
In the first life, Alessia Santos died on day 31.
Alone. Starving. Forgotten.
She wasn't killed by violence. Wasn't murdered or eaten or torn apart.
She died because she cared.
Because she gave until there was nothing left.
Because she believed — until the very end — that things would get better.
No one remembered her name.
No one mourned her passing.
She became just another frozen corpse in a building full of them.
Forgotten.
XII. THE RETURN
PRESENT — DAY 13
Jae-Min opened his eyes.
The bunker ceiling stretched above him. Warm air circulated through the vents. Generators hummed.
Alive.
He was alive.
And so was she.
XIII. THE VOW
He sat up slowly. The wound in his side protested — but he ignored it.
Three days of recovery. Three days of her care.
Her hands on his skin. Her voice in his ears. Her presence real and alive and here.
In the old world, she had starved to death helping strangers.
In this world, she would live.
He would make sure of it.
Whatever it takes.
XIV. THE PROMISE
He rose from the couch.
Walked to the hallway.
Stood in the doorway of her room.
Alessia slept in the small bed — the first real sleep she'd had in days. Her face was peaceful. Alive.
He watched her for a long moment.
Then turned away.
"Three days," he murmured. "Then we prepare for war."
But this time, I'm not letting you sacrifice yourself.
This time, you survive with me.
INNER MONOLOGUE — JAE-MIN
She died alone.
Starved to death in a frozen room because she gave everything to people who couldn't save her.
In the first life, I was too weak to help. Too broken to matter.
But this life is different.
I have walls. Weapons. Supplies. Knowledge.
I have the power to change the ending.
Alessia Santos will not die in a frozen room this time.
She will not starve while strangers take everything she has.
I won't allow it.
Whatever violence is required. Whatever enemies must fall. Whatever lines must be crossed.
She lives.
Even if I have to burn the whole fucking world to keep her warm.
