Reborn With The Milf "Harem" System

The classroom was buzzing like a kicked beehive. Everyone whispering about the new teacher, guys pretending not to drool, girls already gossiping about her skirt and shoes.

Me? I was frozen.

Saki Hoshino stood at the front like she belonged here, like she hadn't dissolved in my arms just nights ago. She wrote her name on the board, crisp strokes of chalk, hips shifting with every line like she knew exactly what she was doing.

Kai elbowed me. Hard.

"Yo, bro, why you standing like you just saw Jesus with tits?"

I didn't answer. Couldn't.

Aki leaned back in his chair, eyes slitting at me. His voice came low, cutting through the noise.

"You know her."

It wasn't a question.

I forced my jaw to unclench. "She's just… a teacher."

Aki's stare didn't break. Kai, meanwhile, was whispering like an idiot:

"Holy shit, Renji, she's hot. Like, my future wife hot. If she ever bends over at the desk, I'm gone. Dead. Funeral's on Friday."

I almost punched him. Not because he was wrong—Saki was all woman now, curves in all the right places—but because every second she was here, breathing, real, I felt like my brain was being split in half.

And then her eyes found me.

Sharp. Direct. Like she'd been searching the whole room just to pin me down.

Her lips curved. A smile. Small, private, like a secret slipped between just the two of us.

The System purred in my head, voice dripping smug.

> [Mmm, she remembers, Renji. Look at the way she stares… hungry. Ready. That's not just a teacher, that's your next conquest.]

I swallowed hard, heat crawling up my neck.

Kai nudged me again, grinning.

"Dude, why's she looking at you like that? Did you, no way. Did you already—"

"Shut. Up." My voice came sharper than I meant.

The whole row blinked at me. Kai laughed it off. Aki didn't.

And Saki?

She just turned back to the board, smile still lingering, like she had all the time in the world to watch me crack.

---

"Alright, everyone," Saki's voice rolled over the class like velvet, steady and confident.

"Let's begin."

Chalk scratched across the board, neat kanji spilling into tidy rows. Every guy in class pretended to copy notes while really staring at her legs. Every girl whispered about her blouse, her hair, her everything.

Me? I couldn't take notes if my life depended on it. My pen just hovered, useless, while my brain screamed:

She's not supposed to be here.

Her curves swayed just enough with each movement, the faint pull of fabric across her chest daring anyone to look away. She was older, hotter, more real than the girl I'd held when she vanished like light in my arms.

> [Mmm, she aged well, didn't she?] the System hummed in my ear, sultry as sin. [Her body's ripe, dripping with need. Imagine bending her over that desk, Renji. Every man in here wants it but only you can take it.]

I tightened my grip on my pen until it nearly snapped.

Across the aisle, Kai leaned over, whispering, "Bro. Bro. Look at those hips. Tell me I'm not hallucinating. Please. Please tell me she's not real or I'm about to commit crimes in my head."

"Shut the hell up."

Kai grinned like a devil. "Wait… why're you sweating? Oh my god! Renji. You know her, don't you?"

I didn't answer.

But Aki didn't need me to. His eyes were sharp, narrowing at me like he'd just put another piece of the puzzle together.

Saki turned then, her gaze sweeping the class before landing square on me. Again. Too long. Too deliberate.

"Renji Sakamoto," she said suddenly.

The whole room turned to stare. My heart stopped.

"Read the passage on page twelve for us."

I swallowed, flipped open my book with shaky fingers, and started reading aloud. My voice sounded normal enough, steady, maybe even bored but inside?

I was burning alive.

Because every syllable I spoke, she held my eyes. Unblinking. Smiling faintly.

Like she wasn't listening to the words.

Like she was listening to me.

---

My voice stumbled through the last line of the passage. The second the words left my mouth, Saki gave a soft clap of her hands.

"Good. Thank you, Renji."

The way she said my name, low, smooth, intentional, sent a ripple of whispers through the class. Kai leaned forward, wide-eyed.

"Bro," he hissed, "why does she sound like she's undressing you with her voice?"

I ignored him, but my ears burned.

Saki turned back to the board, continuing the lesson like nothing happened. But every so often, she'd glance my way. Not long, not obvious, just a flicker. Like checking if I was still there. Like confirming I was real.

By the time the bell rang, the room buzzed with relieved chatter. Desks scraped, chairs clattered, people rushed for the door.

"Yo, Renji, let's hit the cafeteria," Kai said, smacking my shoulder. "Parfaits, remember?"

I opened my mouth, but stopped when Saki's voice cut through.

"Renji. Stay a moment."

The whole class froze. Heads turned. Even Aki's sharp gaze flicked between me and her, measuring every detail.

Kai grinned like he'd just won the lottery. "Ohhh shit. Someone's in trouble. Or…" His eyes gleamed. "…someone's about to get lucky."

"Shut it," I muttered.

But my pulse thundered.

Because Saki was looking straight at me—calm, composed, but her eyes burning with something I couldn't place.

The last of the class filed out, Kai dragged by Aki, who didn't stop staring even as the door slid shut.

And then it was just me. And her.

The System purred inside my head:

> [Alone at last. Mmm… let's see how far your "teacher" plans to take this.]

Saki leaned back against the desk, crossing her legs slow. Deliberate. Her blouse stretched faintly across her chest as she folded her arms.

Her smile was small. But her eyes? They said everything.

"Renji," she murmured, voice low enough only I could hear. "We need to talk."

The silence stretched, thick as smoke. My palms itched, legs ready to bolt, but Saki didn't move.

She tilted her head slightly, studying me like she was dissecting every twitch of my face.

"Renji," she said again, softer this time. "You've… grown."

The words hit strange. Not teacher-to-student. Not polite. More like she was comparing me to someone she'd known before.

I forced a smirk. "Guess that's what happens in high school."

Her lips curved, but her eyes didn't let go of mine. "No. That's not what I mean."

The System hummed, sly and smug.

> [Ohhh, she remembers. Not everything, not yet… but enough. Look at the way she's tasting your name. Like she's testing reality itself.]

I swallowed, throat dry. "So… what did you want to talk about?"

Her gaze sharpened. She glanced at the door—empty, silent—then back to me.

Finally, she spoke.

"Do you believe in… impossible things, Renji?"

The air froze.

I knew that voice. That tone. It was the same girl who'd whispered "I'll be back" before dissolving into light.

I clenched my fists under the desk. "Depends what you mean by impossible."

Her smile grew, faint but undeniable. "Good answer."

She pushed off the desk, brushing close as she passed me, the faintest trace of her perfume, something warm, mature, intoxicating, lingering in the air.

At the door, she paused. "Lunch is short. Don't keep your friends waiting too long."

Then she was gone.

Leaving me alone with a heart that wouldn't calm down.

And a System that was practically purring in my skull:

> [Mmm, soldier-boy, you're fucked. And not in the fun way. Yet.]

---

The cafeteria was its usual zoo.....shouting, tray clattering, the smell of curry and fried bread mixing into a cloud of chaos.

Kai waved like a maniac the second I stepped in, nearly knocking his juice over. "Renji! Over here, zombie-boy!"

I slid into the seat across from him, trying not to look like my insides were still vibrating.

Kai squinted. "Yo… you look like you saw a ghost."

I almost choked on my water. "What?"

He grinned, jabbing his spoon at me. "You did, didn't you? Bro, was it hot? Don't tell me it was a busty ghost chick in the locker room."

I deadpanned. "It was your mom."

"Bastard!" he howled, nearly spraying rice across the table.

The people around us laughed, and for a second, the noise almost grounded me. Almost.

Aki was quieter, picking at his food with that same sharp calm. His eyes flicked to me, dark and unblinking. "You're distracted. More than usual."

Kai snorted. "Man, he's just horny. That's his natural state."

"Not this time," Aki said. He leaned forward slightly, voice low. "Something happened. Didn't it?"

The spoon paused halfway to my mouth.

I forced a smirk, raising a brow. "You always this dramatic at lunch, detective?"

Aki didn't flinch. "Call it instinct. You've been carrying yourself like you're living two lives. Like the classroom isn't where your mind really is."

The words sat heavy between us.

Kai blinked, then burst out laughing. "Bro, you sound like you're accusing him of being Batman."

"Maybe I am," Aki muttered.

The System cooed in my head:

> [Mmm, he's peeling the mask, Renji. One push, and he'll see through you completely. Careful now… or let him see. Wouldn't it be fun to drag a boy like him into your chaos?]

I crushed a piece of bread in my hand without meaning to.

"Relax," I said finally, flashing Kai a grin, then flicking my eyes to Aki. "I'm not Batman. Just a guy trying to survive homeroom without strangling you two."

Kai laughed so hard he nearly spilled his tray. Aki leaned back, but his gaze lingered, sharp and untrusting.

I chewed my food like nothing was wrong.

But inside? My chest was a battlefield.

Because Saki's voice was still echoing, soft and impossible:

"Do you believe in impossible things, Renji?"

And I knew, lunch with the boys wasn't going to be enough to distract me this time.
