Undercover High School

Chapter 13 – The Mirror Breaker

Alister smirked. “You think I’m not ready for this?”

He pressed a key. The backup protocol activated instantly. His personal firewall rose like an impenetrable wall of steel. The malware bounced off harmlessly. But that also meant the Cyber Dragon now knew it was under attack.

This was no longer a silent hunt.

It was war.

Two cyber geniuses, lurking behind their screens, slashing and shielding in a world without sound, without bullets—but just as deadly.

Alister didn’t retreat. He launched one final file: Mirror Breaker—his ultimate program. Not only would it disable the server, it also created false reflections across the entire network, making it look like the Black Dragon system was being attacked from ten different locations at once.

The Cyber Dragon began to panic. Alister could see the system tremble—log files in chaos, defenses misdirected.

At that moment, Alister’s hijack program reached the control center. Funds began to shift—one by one, thousands of transactions reversed, funneled back into the victims’ accounts.

That night, a major crime lost its fangs.

And as Alister closed his laptop, he knew... this wasn’t over.

The Cyber Dragon would come for him. But that’s exactly what he was waiting for.

Yoona met with Reino Ezra.

“Long time no see,” Reino greeted her.

“Yeah,” Yoona replied as she sat on one of the chairs and popped open a can of soda she had grabbed from the fridge.

“So? Have you managed to trap Ray? Or are you two getting close? I heard you’ve been spending a lot of time together,” Reino asked, lighting a cigarette.

“Hah, just like you said. He’s too perceptive and not stupid. I got exposed before I could even start the plan to make him fall for me,” Yoona complained.

“Told you. Ray Valen’s not an ordinary guy. You can’t fool him with the usual feminine tricks.”

Yoona tilted her head, watching Reino over the rim of her half-finished soda can. Her breath was heavy, like she’d just unloaded a weight she’d been carrying.

“I thought he was just some punk who liked illegal racing and picking fights,” Yoona said quietly. “But he’s not. Ray Valen, or Alister… he’s like a living radar. He can read your movements, your tone, even your intentions. No wonder people respect him.”

Reino nodded slowly, exhaling smoke toward the open window. “He was trained. Since he was a kid. Not just in martial arts—but how to think, how to find weaknesses, how to survive. He’s like a blade sharpened so finely it could cut air.”

Yoona let out a dry laugh. “Sounds like you’re in love with him.”

Reino raised an eyebrow. “Nah. I’m normal,” he said, then went quiet. “We were close—like two halves of the same whole. That was before the incident.”

Silence. Only the soft clink of Yoona placing her soda can on the glass table could be heard.

“Well, what’s done is done. A grudge is still a grudge,” Yoona said firmly.

Reino turned his face away, staring blankly out the window. The last wisp of cigarette smoke faded along with memories he didn’t want to name.

“I used to think he was the most loyal brother I ever had,” Reino said softly. “But after everything… you know, sometimes the person closest to you is the one who stabs you first.”

Yoona turned to him, her gaze sharp yet still filled with curiosity. “That incident… was it really all because of him?”

Reino gave a small, bitter laugh. “All the evidence pointed to him. Unfortunately, he never got the punishment he deserved. That’s why I’ll keep chasing him until he pays for what he did.”

Yoona stared blankly at the wall. Her eyes reflected her own image in the glass table.

“Irony, huh? From best friends to bitter enemies,” she whispered. “Betrayed by the one you trusted.”

Reino stubbed out his cigarette in the ashtray, then looked at Yoona seriously. “If you want to bring him down, you need to be more than clever. You need to become a real threat. Something he’d never see coming.”

Yoona slowly stood. Her aura shifted—no longer soft and sweet, but firm, bitter, and laced with old wounds.

“I’m done playing nice,” she said, eyes cold as they met Reino’s. “From now on, no more sweet, innocent Yoona. No more undercover girl with the gentle smile.”

“Then who are you now?” Reino asked flatly.

Yoona walked to the door, opened it, then glanced over her shoulder. A thin, bitter smile curved her lips.

“The enemy he never saw coming.”

The door shut behind her. Reino exhaled deeply and leaned back in his chair.

“Yeah… maybe now, all these grudges will finally be settled,” he muttered.
