Chapter 84: The Lunatic Who Turned Into a Very Strict “Teacher”

Legion was in full celebration mode. They’d fought a suspected Lamia—and zero casualties. Of course it was a party.

Jae-hyung, who’d been whining in Yong-yong’s arms minutes ago, now stood perfectly fine, basking in the joy. Lee Chae felt guilty—he’d pushed Jae-hyung too hard—so he couldn’t fully enjoy it.

“Jae-hyung-ssi, you sure you’re okay? I can guide you if you need it.”

Jae-hyung smiled brightly.

“I’m fine. This is all thanks to you, hyung-soo-nim.”

“What did I do? You saved us all.”

Jae-hyung scratched his head shyly, then started bragging to the espers—exaggerating Lee Chae’s role even more. Soon everyone was chiming in, praising Legion’s only guide for the big save.

It felt good to be recognized, but he’d only shared textbook knowledge—nothing worthy of this hype.

More than that, Haejin’s intense, sleazy stares from across the room were driving him crazy.

Right after faking injury to trick Lamia, Lee Chae had run to check Haejin first. Steel-body or not, fighting a boss that long had to leave damage. Luckily only minor burns and scrapes. He’d wanted to strip him for a full check, but too many eyes.

Since then, Haejin hadn’t looked away once.

Jin-woo, watching them both, finally said,

“Just go to your room already. Stop making everyone uncomfortable.”

Lee Chae stammered, face flaming.

“W-what? Me? Why…?”

Jin-woo poked Haejin’s shoulder.

“Can’t you see his face? He’s practically drooling.”

Lee Chae went silent, cheeks burning. Jin-woo tsked.

“Ever since you figured out how to beat Lamia, he’s been like this. Singing about how his Chae is perfect outside and has a sexy brain.”

Other espers dug fingers in ears dramatically.

“My ears were rotting.”

“Guide-less life is suffering.”

“But seriously—brain sexy is real. Nothing worked, then boom, genius idea.”

“We really picked the jackpot guide. Total win.”

Whistles and teasing everywhere. Lee Chae couldn’t take it—he fled down the hall to the room. The lovey-dovey teasing was embarrassing, but being called the best guide? That was overwhelming.

Being treated better than human by A-ranks and above was weird enough— now unanimous praise for his ability?

It was unfamiliar, flustering, shy-making— but thrilling, heart-racing.

Jae-hyung had done the real work, yet they recognized his effort too—he was grateful.

I like this more than I thought. So childish.

He pressed burning cheeks with both hands to cool them. Turned—and caught Haejin peeking through the cracked door, still half-dazed.

“Come in or don’t. What are you doing?”

“Wondering if a lowly esper like me can enter the room of the brilliant Guide Jung Lee Chae.”

“What nonsense?”

The dumb joke meant he was back to normal. Haejin slipped in grinning, shut the door, and crushed Lee Chae in a hug. Chin on shoulder, stroking his back, whispering,

“So proud. My guide.”

Soft voice sank straight into his chest. Lee Chae knew Haejin said it often to ease his inferiority complex. Knowing didn’t stop the same-sized wave of emotion every time.

He hugged tighter.

“Thank you for being proud of me.”

Voice watery despite trying not to cry. Haejin chuckled, patting his back—then slid hands lower down the spine.

“Too bad we’re invincible together.”

“Why?”

“If I got a little hurt… we could do intense guiding…”

Lee Chae kicked his shin.

“You never last five minutes without ruining the moment.”

Haejin rubbed his shin, whining.

“Now kicking too… domestic abuse, I’m repo—”

“Want real domestic abuse? I told you—no talking about getting hurt or dying.”

Lee Chae huffed. Haejin laughed, pulled him closer. Lee Chae resisted—but ended up in his arms anyway.

“Sorry. I’ll stop joking.”

“You always say that.”

“Voice all pointy.”

Lee Chae sighed. Pranks, pervy talk, occasional questionable humanity—all forgivable. But casually mentioning injury after Lee Chae begged him not to? Unbearable. Extreme measures needed.

He looked up. Clear, innocent eyes gazed down. He steeled his weakening heart and lowered his voice seriously.

“I didn’t say this before because I didn’t want to upset you…”

Haejin’s right eyebrow twitched.

“I… actually like really mature types.”

Brow fully furrowed. Haejin sounded suppressed.

“Mature? Like what? Examples?”

“You know… grown-up vibe? Daddy-ish, teacher-ish…”

Looking at Haejin’s face, Lee Chae had a weird thought: He’s not mature, but definitely daddy and teacher material. Elementary-school antics aside—his looks scream sexy adult.

He paused, studying Haejin slowly. Sharp jaw, upturned eyes, straight nose, gaze that could burn— red lips parted slowly.

“Daddy and teacher? You like old geezers?”

Angry scowl somehow made him sexier.

Am I insane? Full pervert now?

He’d started this to cure Haejin’s habit— now he was the one in trouble.

“Why no answer? I asked.”

Voice sharp. Throat bobbing with suppressed anger. Lee Chae swallowed involuntarily watching it. Haejin smirked.

“You sexually harass with your eyes, then say I’m not mature?”

“I never—harass what—”

It’s harassment. Creepy level.

“If that’s what you like, I can be teacher or daddy anytime.”

Eyes dripping desire stared down. Anger or sudden impulse—impossible to tell. That licking gaze made breathing hard.

A long hand gripped Lee Chae’s nape. The other brushed shoulder, grazed chest. Lee Chae flinched, looked up.

“Want that? I’ll do it.”

Sticky gazes locked. Shit, this isn’t what I planned… how did it turn like this? He needed to escape the suffocating mood—brain malfunction, no thoughts.

Insane thirst surged. Overwhelming urge for Haejin to do something. Reason screamed wrong move and you’re dead— but barely held the impulse.

“N-no… hyung, listen. I was joking. You keep talking about getting hurt—it upsets me…”

Before he finished, Haejin’s arm snaked around his waist.

“Mmph…!”

Lips crashed. A kiss that swallowed him whole—reason snapped completely. Post-battle heat made the imprint spot tingle.

“Haa…”

Lee Chae clung desperately, sucking lips fiercely. Haejin breathed rough heat, pushing closer.

They collapsed onto the bed; the second lips parted Haejin dove back in. Sticky, wet sounds—Lee Chae’s breathing turned frantic. Kiss alone nearly sent him over.

“Ah… more, more…”

The thirst he’d felt since Haejin’s scowl worsened. Kissing wasn’t enough—he wanted to devour.

Haejin pulled back slightly, whispered,

“Guide-ssi, so horny.”

“Haa, shut up and kiss me.”

Haejin bit his lower lip hard—blood taste, but no pain. Actually clarifying.

Hand slid up thigh, gripped nape tight.

“Student’s too rude.”

What now? Eyes still lust-glazed, breath hot—definitely not joking. Lee Chae blinked once.

Meanwhile buttons undone one by one.

“What do rude students get?”

Voice low, deadly. Shirt opening. Thirst exploded— Lee Chae’s last coherent thought: I’m so screwed.

The lunatic smirked down at his helpless hamster, ready to give the “lesson” of a lifetime.
