Revenge Karma: She Broke Our Childhood Promise, But Her Tomboy Best-friend Saved Me.

The Seed Takes Root



(PoV: Kurone)

The bell rang, a harsh, metallic screech that echoed across the frost-bitten courtyard, signaling the beginning of homeroom.

Around me, the sea of students began to part, flowing in a hurried mass toward the heavy double doors of the main building.

But my feet felt glued to the concrete.

I stood by the cold brick pillar, feeling my breath pluming in the frigid morning air, my heart hammering against my ribs so violently I thought it might crack my sternum.

The morning chill, which only moments ago had felt like a refreshing backdrop to my perfect life, suddenly felt suffocating as it bit through the thin fabric of my designer school blouse.

I wrapped my arms around my waist, my manicured fingers digging into the dark fabric of my blazer until my knuckles turned a bruised, stark white.

'What just happened?'

The question bounced around the hollow chamber of my skull, refusing to settle. My brain was a chaotic, spinning whirlwind of fragmented images, impossible data, and sensory anomalies that simply did not fit into the narrative I had so carefully constructed.

'Shin and Akane. Together. Walking into school side by side.'

But it wasn't just the fact that they had arrived together, since it could have been a coincidence.

No, the thing that was making me feel that way was the way they had looked.

They were too close, and for some reason, I felt entirely excluded.

Moreover... Shin hadn't looked at me. 'Is he still upset because I made him pay yesterday? Well, it was his fault. He should apologize.' I thought.

For as long as I could remember, Shin's eyes had been a compass that always, inevitably, pointed to my north.

No matter who was talking, no matter how crowded the room was, no matter what dramatic event was unfolding, if I was in the vicinity, Shin was looking at me with that pathetic, sweet devotion that made me feel so incredibly secure, so universally loved, so powerful.

Even yesterday, after he had said those mean, horrible things at the café—calling me a "burden," telling Kenji he was glad to be rid of me—I hadn't truly believed a word of it.

I knew he was just acting out. I knew he was just throwing a childish, desperate tantrum because he was jealous of Kenji, since I was giving more attention to him. He probably started to feel insecure, who knows.

When Shin walked away, I figured he would stomp off, go home, cry into his pillow until his eyes were red and swollen, realize the absolute impossibility of living his life without my light, and come back today to apologize and be best friends again.

But today... Today, he had looked right through me.

When my eyes had searched his, seeking that familiar, desperate apology, I found a void.

I saw him staring at Akane with a singular, unwavering intensity that made my stomach drop. It wasn't the soft, in-love look he gave me; it was something harder, darker. Something that completely locked me out.

He hadn't even flinched when she touched his hair.

My stomach churned, a sudden, violent wave of acid rising in the back of my throat. I had to swallow hard, closing my eyes against the sudden wave of vertigo.

Akane never touched people because she always hated physical contact.

She was the edgy, unapproachable girl who sat in the back of the class and scowled at anyone who breathed too loudly near her.

I kept her around as a "best friend" precisely because her dark, abrasive personality made my sweet, radiant "angel" persona shine a hundred times brighter. She was the perfect contrasting background for my masterpiece, and she was good at giving advice.

I had always been the pretty one. The soft one that boys wanted to protect.

Akane was... different. Sharp. Angular. She looked like she could hurt you if you got too close.

But Shin had never looked at her before. Not like that.

So what had changed?

Was it the way she dressed? The way she didn't care? The way she looked at him was like he was the only person in the room?

I glanced down at my own reflection in the glass door of the school entrance. Pink ribbon. Perfect hair. Gentle smile.

I looked like a doll.

And dolls, I realized with a shiver, were meant to be played with. Not loved.

But she had reached up and slid her fingers into the nape of Shin's neck with an effortless, possessive familiarity that made my skin crawl with pure revulsion.

And... Shin had let her. He even leaned into it.

"I gave him a hot breakfast, made him take a long shower, and gave him a change of clothes."

The words echoed in my ears, mocking me, before I looked down at the heavy gold ring catching the pale winter sunlight. I needed to distract myself and 'think positive'.

Kenji had given it to me, a beautiful and expensive gift. The ultimate status symbol that proved to the whole school that I was the queen, that I had secured the best, most athletic, most popular guy in our entire year.

When Kenji slid it onto my finger, I felt like I had conquered the world. I had everything I wanted. I was the undisputed protagonist of this high school. I was happy, because I've liked Kenji for a long time. Four months, I guess.

But suddenly, staring at the glittering diamond, the ring felt like a heavy, suffocating shackle.

'Did Shin sleep at her place?'

I didn't know where this question came from, but the only thought of it was a physical blow to my abdomen.

'Did he sit on her couch? Did he take off his clothes in her apartment? Did he stand naked under her showerhead? Did he wear her clothes? The black shirt he had on today... It clearly wasn't his. It was too stylish, too dark.'

'No,' I told myself, shaking my head frantically, my strawberry-blonde hair whipping around my shoulders. 'No, no, no. Shin wouldn't do that. Shin loves me dearly. He wouldn't cheat on his best friend.'

He has loved me since we were ten years old, and even promised to marry me in that sandbox. I remembered his blushing face, his trembling pinky finger wrapping around mine.

He was a boy who worshipped loyalty. He wouldn't just... move on. He couldn't just switch off seven years of adoration in one night. And with Akane? The girl who mocked romance? The girl who didn't even own a lip gloss? Impossible.

"I'm seriously thinking about hitting on him."

Akane had said it was a joke, laughing with her abrasive, loud laugh, but I also knew Akane didn't make jokes like that. Not when it came to feelings.

I didn't know what else to think, until terrifying, suffocating panic began to wrap its icy fingers around my throat, squeezing until I couldn't draw a full breath.

"I don't want to lose my best friend," I muttered to the air.

Everything around me was shifting, twisting into a shape I didn't recognize, and I wasn't the one holding the pen anymore.

I had planned every single moment perfectly. Kenji was supposed to be the gleaming trophy I paraded around the hallways, the boyfriend who gave me the social dominance I deserved. But Shin... Shin was my safety net. He was the emotional foundation of my confidence. I didn't want to lose him, not after all this time, and I really hoped that he could become friends with Kenji.

I really wanted that, with all my heart. I just wanted to be happy.

Kenji was fun, but I also knew that he wouldn't sit on the phone with me for three hours at midnight just to listen to me complain about a bad grade. Kenji wouldn't memorize my exact tea order. Kenji wouldn't drop everything to bring me an umbrella in the rain.

So... Shin was supposed to be the unconditional, eternal backup plan. He was the ground I walked on. He was mine.

I couldn't lose him. And I absolutely, unequivocally could not lose him to a girl who wore combat boots, listened to weird, distorted music, and looked like a delinquent.

I couldn't lose my loyal, devoted friend to my cynical, cast-off "best friend."

The humiliation of it would destroy me. If the school thought that Shin had upgraded from me to her, my status as the perfect, untouchable angel would shatter.

I needed to fix this.

I stopped pacing and then planted my feet firmly on the concrete, forcing the panic down into a tight, hard little box in the center of my chest. I couldn't let my emotions dictate my actions. I had to be smart.

I needed to remind Shin of what he was missing. I needed to shatter whatever temporary, trauma-induced illusion Akane had spun around him.

I needed to show him that Kenji and I were the perfect, radiant couple, and that he should be aspiring to be close to us, not running off to play house with the school's resident outcast.

I needed to avoid every contact between them and pull him back into my orbit where I could control the gravity, dictate the terms, and feed off his adoration once again.

'A double date,' the thought sparked in my mind like a brilliant, blinding flash of lightning.

Yes. That was it. It was the perfect, flawless strategy.

I would organize an outing. Kenji and I, alongside Shin and Akane. I would frame it as a celebration of my new relationship and play the part of the gracious, loving best friend who just wanted to include everyone in her happiness.

I would be so sweet, so impeccably kind, that Shin would realize I was still the pure angel he adored. I would wear the pink sweater he bought me for my birthday last year and tilt my head just the way he liked while laughing at his jokes.

But more importantly, I would force Akane to sit there and watch.

I would make her watch as Kenji kissed me, as he bought me things, as he treated me like a princess. And I would make Shin watch it, too.

But it wasn't just about showing off. It was about control.

Every time Kenji kissed me in front of Shin, a little part of Shin's heart would crack. I had seen it happen before — the way his jaw would clench, the way his eyes would drop to the floor, the way he would swallow hard like he was trying to keep something down.

I needed to see that again.

I needed to know that I still had the power to hurt him, because if I could still hurt him, it meant he still cared. And if he still cared, I could still pull him back.

The kisses weren't for Kenji. They were weapons. And I was going to aim them directly at Shin's chest.

I would stoke the fires of his jealousy until anything Akane had put in his head burned away, and would make it so painfully obvious that she could never offer him the kind of light and beauty that I possessed.

I would put her right back into her place as the edgy, undesirable sidekick, and I would put Shin back where he belonged— by my side, looking at me like I was the sun.

I wasn't being cruel. I was just... reminding him. Reminding him of what we had and that I was the one who made him feel alive.

But even as I thought it, a cold sliver of doubt wormed its way into my mind.

What if she wasn't the sidekick?

What if, in his eyes, she had become... something else?

Akane was smart. Smarter than me, probably.

She didn't need validation from anyone since she always wore what she wanted, said what she wanted, and didn't care if people stared.

I had always admired that about her — and hated her for it at the same time.

Because if Shin was looking for someone real, someone who didn't wear a mask...

...what chance did I have?

I crushed the thought immediately. I was the angel. I was the one everyone loved. She was just a phase. A strange, confusing detour on Shin's journey back to me.

I took a deep, steadying breath, the icy air filling my lungs and clearing the last of the panic from my brain. I smoothed down the pleats of my skirt, adjusted the pink ribbon in my hair, and pasted my signature, flawless smile back onto my face.

The bell was just an echo now. The courtyard was empty, except for me.

'You're not going anywhere, Shin,' I thought, my eyes narrowing into calculating slits as I looked toward the heavy glass doors of the school entrance. The cold, black disgust he had shown me this morning was just a phase. It had to be.

'You belong to me. You have always belonged to me.'

The words felt right on my tongue, familiar and comforting. But underneath them, buried deep where I didn't want to look, something stirred.

A voice, small and terrifying

'What if he doesn't come back?'

My hands started to tremble unconsciously. I shoved them into the pockets of my blazer, hoping no one would see.

'No. He will come back. He always came back.'

But the voice wouldn't quiet.

'What if this time... he doesn't?'

I turned and began to walk toward the building, my Mary Janes clicking sharply against the pavement.

I was about to claim what was mine.
