Yu Ren stirred awake before dawn.
The room was still dark, except for the faint glow from the dying embers in the hearth. Kai sat by the window with his knees drawn to his chest, watching the horizon as the first light bled into the broken skyline. His profile was unreadable—quiet, but alert.
"Did you sleep?" Yu Ren asked groggily, voice rough with sleep.
Kai didn't turn. "A little."
Yu Ren sat up, pushing the blankets off. His body ached with yesterday's training and travel, but there was no time to rest. The strange, mutated animal encounter and the half-map they found made everything feel more urgent.
He rubbed his face and asked, "What's on your mind?"
Kai turned slowly. "The route marked on that map… I think it leads to a weapons stockpile. Government facility. Pre-apocalypse."
Yu Ren blinked. "You're sure?"
"I'm not sure of anything," Kai replied. "But the symbols—they match military cipher markings. At least, what I remember from—" He stopped himself.
Yu Ren didn't push. Kai had been revealing more, piece by piece, and Yu Ren had learned to wait.
After breakfast—dried meat and protein cubes from their system rewards—they spread out the scavenged half-map on the table, held down by a rusted knife and an empty jar.
Some of the landmarks matched the real world. There were twisted train tracks and an old windmill they passed on their way into this area. The mark was in red ink—X over a region near a collapsed tunnel.
"It'll take two days if we go by foot," Kai said. "More, if there are mutants. And there will be."
Yu Ren leaned closer. "Do you think this stockpile still exists?"
Kai didn't answer for a long time. Finally, he said, "Even if it doesn't… people believe it does. That makes it valuable. Dangerous."
Yu Ren's eyes narrowed. "You think others are after it?"
"I know they are," Kai murmured. "I've seen this kind of thing before. People chasing rumors, dying for myths. The difference is—this one might not be a myth."
---
They left the safehouse an hour later, both armed and alert. Yu Ren brought the rifle from the military van and his makeshift blade. Kai had his usual knife, now visibly sharpened, and a new pair of scavenged gloves.
By midday, the terrain changed.
It was no longer quiet ruins—they were moving into dead forest territory, with trees that grew bent and blackened, as if scorched by invisible fire. A strange sulfuric scent hung in the air, and the ground squelched slightly underfoot.
Yu Ren frowned. "System said this area had minor contamination."
Kai stepped carefully, gaze sharp. "Contamination spreads. Just because it was minor before doesn't mean it still is."
As if summoned, the sound of movement echoed from ahead—low, wet dragging. Then a screech.
They froze.
From behind the blackened trees emerged a creature that might have once been a wolf—except its body was wrong. Bulging muscle. Exposed ribcage. Eyes that glowed faint yellow. It stood on three legs, the fourth a mangled limb that dragged behind like a club.
"Mutant," Kai hissed, stepping in front of Yu Ren.
But the creature didn't rush them. Instead, it watched, tilting its head. Then it backed away slowly, still facing them, and vanished into the woods.
Yu Ren let out a slow breath. "Why didn't it attack?"
Kai was still tense. "It was testing us. Or warning others."
Yu Ren's skin crawled.
---
That night, they didn't make a fire. They set up camp beneath an overhang, wrapping themselves in tattered thermal blankets salvaged from the bunker weeks ago. The stars overhead were dim and scattered, like dust.
"Do you trust me now?" Yu Ren asked, breaking the silence.
Kai looked at him sideways.
"I mean it," Yu Ren said. "You always act like I'll suddenly betray you, or get myself killed, or… something. But I've made it this far."
Kai was quiet. Then: "Trust isn't about the number of days. Or survival counts. It's… slower."
Yu Ren chuckled dryly. "So what am I to you now, then?"
Kai's gaze dropped to the ground. His voice was barely audible. "Important."
Yu Ren blinked.
"I don't know what to call it," Kai added, slightly frustrated. "But I don't want you to die. That has to mean something."
Yu Ren felt heat rise to his cheeks, even in the cold. "Well. Good. Because I don't plan on dying either."
They didn't say anything after that.
---
By the morning of the third day, they reached the edge of the marked area on the map.
The landscape here had changed again. A wide pit stretched before them—collapsed road, half a city block swallowed by the earth. In the center stood the rusted remains of a communications tower, barely standing.
But more than that—there were signs of recent movement. Scavenger footprints. Rope marks. And blood.
Kai knelt by a disturbed patch of dirt. "Someone was dragged here."
Yu Ren looked around, rifle ready. "Recently?"
"Two days ago. Maybe three. Before the rain washed some of it away."
Yu Ren's jaw tightened. "So we're not the only ones who found this place."
"No," Kai said. "And they may still be here."
Suddenly, a click echoed from behind them.
Yu Ren turned—just in time to see three figures emerge from the treeline, weapons raised. One had a makeshift gun, the others long knives.
"Hand over the map," the tallest man said, grinning with bloodied teeth. "And maybe we'll let you keep your boots."
Kai stood slowly, hands half-raised. "We don't want trouble."
The man sneered. "Everyone says that. Right before they scream."
Yu Ren glanced at Kai, waiting for a cue. A nod. Anything.
Instead, Kai said, loud and clear: "Initiate System Combat Protocol: Prioritize Threat Elimination."
A faint hum activated behind Yu Ren's eyes.
[Combat Protocol Engaged.]
[Kai: Tactical Module Active.]
[Yu Ren: Support Mode Enabled – Range priority.]
Yu Ren didn't hesitate.
His rifle fired before the man could blink.

The Room That Wasn't on the Map
Yu Ren's fingers brushed the keypad again. "This one… wasn't on the blueprint, right?"
Kai studied it silently. "No. This room shouldn't exist. The blueprints only showed sixteen living quarters. This would make it the seventeenth."
A chill whispered down Yu Ren's spine. "So it's either an error… or someone wanted this room to stay hidden."
With a faint whir, the door creaked open. The room beyond wasn't pitch black—it was dimly lit by emergency lights along the floor, casting a sterile red glow that made everything inside look like it had been dipped in blood.
What struck Yu Ren first was the smell. Not decay—thankfully—but something chemical. Sharp. Sterile. Like antiseptic or… formaldehyde?
They stepped inside.
It was small, just enough space for one bed, a desk, and shelves lining the far wall. Unlike the dormitories outside, this wasn't personalized. No clothes. No photos. No signs of someone living here.
But someone had been here. Recently.
On the desk sat a file—standard format, much like the ones Yu Ren had seen earlier from the original research team. But this one bore no name. Just a code: SR-K4.
Kai walked over, brushing off a thin film of dust. "This file is classified. The code prefix is different."
Yu Ren leaned over. The top sheet was marked with red ink: "For Project Supervisor Access Only."
"Project Supervisor?" Yu Ren blinked. "Weren't they all gone by the time the outbreak happened?"
"Not all," Kai said, thumbing through the pages. "Look. These signatures… some are dated less than a month before Zero Day."
He pulled one page free and handed it to Yu Ren.
It was a progress log. Written in terse, clinical phrasing:
Subject K4 stability confirmed. Favorability threshold reached. Observation of social-emotional response complete. Proceeding to Phase 3.
Below that, a scribbled annotation:
"Note: Prolonged exposure to Target-019 produces consistent rises in cooperation and restraint. Projector response abnormal—verify if affection is an unintended side effect."
Yu Ren's mouth went dry.
"K4… is that you?" he whispered.
Kai was still. Too still.
Then, softly: "That code. I've seen it before."
He didn't elaborate, but Yu Ren could hear the faint tremor in his voice.
There were more documents. Lab readings. Behavioral data. Even annotated diagrams of the dorm layout—except in those diagrams, Yu Ren's room was marked with a red circle.
The label?
Target-019 (Control).
His breath hitched. "So I… was part of their test?"
"They isolated us on purpose," Kai murmured. "That's why our rooms were next to each other. Why I—why we—"
He trailed off.
Yu Ren turned toward him. "You what?"
Kai looked up. His eyes, usually calm, were shadowed with something tangled—guilt, confusion, maybe even fear.
"I always felt something was off. Like I was drawn to you, but… also programmed to be. Like my instincts were being tugged in ways I didn't understand." He clenched his fist. "If that file's right, they set us up. You weren't just another survivor I stumbled into. You were part of the test."
Yu Ren's chest twisted. "And you were the subject."
Kai met his gaze. "Do you regret it?"
The question wasn't scientific. It was painfully human.
Yu Ren hesitated, then shook his head. "No. But I hate that they decided that for us."
Kai took a deep breath and stepped closer. "Then let's decide the rest ourselves."
Their fingers brushed, briefly. Then Yu Ren stepped back, nodding.
"…There's more here. We're not done."
They finished scanning the rest of the room. A hidden cabinet behind one of the shelves revealed another oddity: a black card with a red star-shaped insignia in the center. No name. No writing. Just a biometric scanner embedded into its surface.
"I think this is a key," Yu Ren guessed.
Kai nodded. "But to where?"
Suddenly, the lights flickered. Once. Twice. Then a klaxon began to sound—muffled, but distinct.
"System override," a static-laced voice announced from somewhere in the walls. "Unauthorized access detected. Quarantine Protocol: Initiated."
Kai swore. "They built an auto-defense system. We triggered it."
Red lights turned blue. A heavy slam echoed outside the hallway.
"We need to move. Now."
Yu Ren grabbed the card and file, and they bolted out of the room just as the metal door behind them hissed and sealed itself shut.
---
They didn't stop running until they reached the elevator shaft—the one leading to the lower sublevels of the facility. The alarm had stopped, but everything felt… different now.
The facility wasn't just abandoned. It had been watching them.
And it was still running protocols that no human had overseen in years.
Yu Ren glanced at Kai, heart pounding. "So what now?"
Kai held up the black card. "Now we find out what they didn't want us to see."

The Rules of Being Broken
The silence between them was different this time.
Not uncomfortable. Not full of unspoken threats or anxious restraint. It was the silence of two people who had seen too much, said enough for now, and were simply… still.
Yu Ren sat beside Kai at the edge of the dried-out rooftop pool, his feet dangling over cracked tiles. The sky above was slowly bruising purple with evening, the wind carrying the scent of smoke and old cement. Far below, the scavenger team had lit a controlled fire in a metal barrel for warmth, their faint voices occasionally floating up in fragments.
"We should sleep soon," Kai said at last, voice low. "It's a long walk to the next safe zone tomorrow."
Yu Ren nodded, but didn't move.
Kai didn't either.
Instead, Kai leaned back on his palms, gazing up at the moon that was trying to rise behind thick clouds. "There was a rule, you know," he said quietly. "Back then. In Project Reverie. No attachments. No empathy. No bonds."
Yu Ren glanced at him. "You broke it."
"I wasn't supposed to care," Kai continued, his eyes far away. "But you were… difficult. Loud, angry. You kept getting into fights. Picking apart everyone's logic. I thought you'd snap. Or die early."
"You thought I was weak?" Yu Ren muttered.
Kai gave him a sidelong look. "No. I thought you were the only one still human."
That silence again.
Yu Ren swallowed the tightness in his throat. He remembered too many things now: flashes of white rooms, fluorescent lights, the echo of doors locking behind them. The way Kai had always appeared right when things were about to go wrong.
"I always hated being told what to do," Yu Ren said after a moment. "Hated that place."
Kai tilted his head. "And now?"
Yu Ren's hand rested near Kai's. Close enough that their fingers almost touched. "I don't know what I feel anymore," he admitted. "But I know I don't hate you."
Kai didn't speak, but something in his shoulders relaxed—like tension had drained from a place even he didn't know was wound so tight.
A notification pinged softly in Yu Ren's mind.
[System Notice: Kai's Favorability has increased by +1.]
[Current Favorability: 93]
[Remark: The wall is cracking. You're not alone in remembering.]
Yu Ren blinked and glanced at him again. "Kai…"
Kai turned toward him, and for a fleeting moment, the mask slipped.
There was fear there—real, raw fear. Not of death, or infection, or the world crumbling around them. But fear of letting someone in again. Fear of needing something. Needing someone.
Yu Ren took the risk.
He laced his pinky finger with Kai's.
Not a full hold. Just a gesture. Something soft in a world too sharp.
"I'm not going to break the next time you disappear," Yu Ren said, almost teasing. "But I'd rather you not vanish again."
Kai stared at their linked fingers.
"I'll try," he whispered.
It wasn't a promise. But it was the most honest thing he'd said all day.
---
They returned to the room, where the cracked window let in just enough moonlight to cast soft shadows. The others were already resting or asleep, wrapped in mismatched blankets and jackets. A few had makeshift beds lined with scavenged curtains or insulation sheets.
Yu Ren curled up near the corner, resting his head against his arm.
Kai didn't sleep immediately. He stood watch near the door, his gaze alert, rifle within reach. But Yu Ren knew that tonight—if he called his name—Kai would come.
Just like before.
Just like always.
