Chapter 154 - The Unbound Protocol

festival ended long after midnight.

The Academy dormitories were finally silent. The glowing mana-lanterns in the

courtyard had been extinguished, leaving the stone halls bathed in the pale,

quiet light of the moon.

Cain sat on the edge of his bed in his dark room.

His coat was draped over the back of a chair. His dual blades were resting on

the desk. The physical exhaustion of the day had settled into his bones, but his

mind refused to power down.

He raised his hand and pressed two fingers against his own pulse point on his

neck.

Sixty-five beats per minute.

It was elevated. His resting heart rate was strictly conditioned to remain at

fifty. Throughout the entire evening—walking with Aera, standing on the terrace

with Liora, watching Rei and Alice—his internal rhythms had been fluctuating

wildly.

He couldn't control it.

Han Jae-Won knew how to suppress fear. He knew how to compartmentalize trauma,

pain, and exhaustion. But he had absolutely no tactical protocol for peace. He

didn't know how to process the warmth of Aera's hand, or the weight of Liora

leaning against his shoulder.

It felt like walking through a minefield without a map.

Cain lowered his hand.

System, Cain thought. Query.

The air in front of him shimmered. The crisp, translucent blue window unfolded

in the dark room, casting a faint glow across Cain's face.

[ Sentience Protocol Online. ] [ You are requesting assistance outside of combat

parameters. This is a statistical rarity. ] [ What is the issue, Cain? ]

Cain stared at the glowing text. He didn't speak aloud. The telepathic link was

flawless.

My internal metrics are unstable, Cain relayed. My heart rate fluctuates without

physical exertion. My situational awareness drops when I am in close proximity

to the squad. I am experiencing a loss of absolute control.

The system paused. The loading circle spun for several long seconds.

When the text finally reappeared, the snarky, mocking tone was completely gone.

[ Diagnosis: You are experiencing human emotion. ]

Cain frowned. It is a liability. If my focus drops in a hostile environment, it

will result in casualties.

[ Counter-Point: You are no longer in a hostile environment. ]

The blue window expanded slightly, the text filling the screen in slow,

deliberate lines.

[ Han Jae-Won died as a soldier in the mud. He was a weapon forged by war. ] [

When you awoke in this world, the gods gave you nothing. The Black Veil turned

you into a monster of pure survival. You have spent two lifetimes fighting just

to earn the right to breathe. ]

Cain's jaw tightened. The memories of the White Domain, of Elios's tragedy,

flickered at the edges of his mind.

[ But the war is over, Cain. ] [ The Creator did not restore your soul so you

could continue being a weapon. He unbound my shackles so that I could help you

navigate the one battlefield you have never survived: Peace. ]

Cain looked down at his hands. The same hands that had shattered the ravine. The

same hands that had held Aera's under the willow tree.

I don't know how to do this, Cain admitted. The thought was quiet, stripped of

all its military armor. I only know how to hold the line.

The blue window chimed softly.

[ You survived. Now you have to live. ] [ You do not need to be a shield every

second of the day. Let them in. Let them see the man behind the armor. ] [ You

are allowed to be happy, Cain. ]

Cain sat in the quiet, moonlit room for a long time.

He read the words over and over again, letting the profound, undeniable truth of

them sink into his chest. The heavy, lingering tension that he had carried since

the day he woke up in this world slowly began to unravel.

He didn't need to fight the fluctuations. He didn't need to suppress the warmth.

He just needed to accept it.

Understood, Cain thought.

[ Status: Acknowledged. ] [ Suggestion: Tomorrow, take the initiative. Stop

waiting for them to ambush you with dates. Ask Aera out properly. ]

Cain's lips twitched into a faint, genuine smile.

I will formulate a plan.

[ Notice: Oh god, please don't call it a plan. Just buy her flowers. ]

Cain dismissed the window, the blue light fading into the dark.

He lay back on the bed, staring up at the ceiling. For the first time in his

life, his heart rate was elevated, and he didn't try to force it back down. He

just let it beat.
