Chapter 10: Classroom Brotherhood Unformed, Renyu Saiki Arrives with Hidden Danger

The onlookers had settled down, pulling out textbooks, chattering about youthful topics.

Some gossiped about who fell for whom, becoming lovers.

Others bragged about someone’s legendary hundred-person conquest in one night, their fame spreading far.

The topics varied, but their core was the same.

Love and lust.

Yet the girl before them ignored it all, focusing on something more important.

Retracting her fingers, Shizuku Sakurai turned with a smile, scooting her chair forward, leaning back until her upper body draped over Su Buyu’s desk.

Her mature curves strained her navy-blue sailor uniform, spilling casually to the sides.

She sprawled defenselessly, her brown hair mussing his neatly arranged books.

Arms dangling off the desk, head resting on it, she gazed up at his light brown eyes, speaking with a hint of confusion.

“Why’d you suggest that? You could’ve stayed out of it with no loss to you, right?”

The boy lowered his head, meeting her pale yellow eyes, their gazes locking.

“Because I think it’s wrong. I’m not siding with the girl or targeting Genichi Fujino. I just think that kind of physical transaction is wrong. I… don’t want it to keep happening.”

Feeling his reason sounded weak, Su Buyu awkwardly looked away, only to feel warmth on his cheeks.

Not the flush of embarrassment from his words.

But Shizuku Sakurai’s faintly warm hands.

Her gentle touch forced his gaze back to her face, her pale yellow eyes radiating a softness that seemed to hide her heart’s tenderness.

She grinned, laughing freely.

Then, her hands gently pulled him closer.

Close enough to see the fine hairs on her face.

Close enough to count her eyelashes.

He’d never been this close to a girl.

Even in game CGs, he never zoomed in, just quietly admired their smiles.

Now, that smile was right before him, a faint tremor rising from his chest.

His heartbeat.

He feared she’d hear it.

He shouldn’t be afraid, didn’t need to be.

But seeing the sincere glint in her eyes, he clenched his teeth, about to speak, when Shizuku Sakurai parted her cherry lips, her mouth curving, eyes like pure crescent moons.

She held his face, asking softly.

“Will you keep this up?”

“…Hm?”

What did she mean?

His mindset?

Well…

Of course he’d stick to it!

His ultimate goal was to defy the Lustful Defiled Gods, not end up as a miserable lump of flesh!

With that thought, his puzzled look hardened, his tone firming up.

He broke free from the odd atmosphere, staring into her lively eyes, pressing on.

“Exactly. So what?”

“You turned around just to ask me that?”

“Not that free, are you?”

He casually brushed her slender hands from his cheeks, lifting his head, almost looking down at her.

Shizuku Sakurai pouted, a bit displeased.

With a slight tug, she pulled his head back down.

His innocent lips went with it.

To her, she was pulling him up.

So in her eyes, Su Buyu was smiling.

“What, I can’t chat with you unless I’m free?”

“Not that extreme, but as classmates, we’re getting a bit too close.”

“Hey! I’ve got a great idea, wanna hear it?”

“What idea?”

Su Buyu felt a bad vibe.

This delinquent girl might say something weird.

But even if it was weird, he’d hear it out before deciding.

Steadying his breath, he nodded, signaling her to go ahead.

“Spit it out.”

“Let’s be brothers!”

“…Brothers? Like, brother-sister brothers?”

“No, like ‘all the world’s my brother’ brothers!”

She spread her arms, face dramatic, like she was nailed to a cross.

Su Buyu’s lips twitched, unsure what to say.

Because one of his hands was pierced.

Kids, this ain’t funny.

The breeze outside ruffled the medical bandages, Su Buyu clenching his fist, feeling the pain in his palm.

“And if I say no?”

“Then we duel. I win, you’re my little bro. You win, I’m your big sis! Heh!”

“…What’s the difference?”

“Simple—whoever wins calls the shots. Isn’t that great?”

She stretched, revealing her smooth, toned abs.

Brief, but Su Buyu caught it.

How to describe it… well, she clearly worked out.

And…

“Whoever wins calls the shots? For anything?”

“Of course! One word from you, and your bro would brave fire and death… if you win, that is~”

She playfully tapped his nose.

Gotta admit, the terms were tempting.

But Su Buyu wasn’t too interested.

“Let’s talk later. For now, we’re just classmates.”

“Huh? Later? No way! Answer now!”

“…Haha.”

Hilarious.

Even Shizuku Sakurai’s thinking was swayed by this world.

Sigh, if he got influenced too, would that count as “corruption”?

Su Buyu gave a dry laugh, about to explain, when a piercing warning blared in his mind.

Buzz—

[Warning, Master: Shizuku Sakurai’s corruption risk is rising. Be cautious of your surroundings and stay safe.]

Huh? Danger?

How?

They were in a classroom!

How could there be…

Click, click, click—

The unsettling sound of high heels echoed outside.

Each step hit like a heartbeat, moving fast. In moments, the classroom door swung open.

A woman in a black OL uniform and glasses stepped in, her image searing into Su Buyu’s mind.

“Ahem, class, there’s a change. I’ll be teaching you all morning.”

Her voice was cold, impatience oozing like sludge, flooding the room alongside her odd pomegranate perfume, invading everyone’s noses.

Like it or not, the students had to endure it.

And…

Accept her lesson.

White chalk scrawled bold words on the blackboard, claiming the space like a conqueror.

She tapped the desk sharply, then shouted at the students.

“Good. Since no one objects, let’s start!

Tell me, what factors ensure proper stress relief? You, girl in the back, answer.

By the way, if you can’t answer, you’ll demonstrate up front.

A… stress relief demonstration.”

Her finger pointed at Shizuku Sakurai, eyes narrowing, lips curling in a barely noticeable smirk.

But Su Buyu caught it.

She was targeting Shizuku Sakurai.

Why?

His gaze fell on the blackboard’s white words.

And the teacher’s name in the corner.
