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

The Long Walk Home



(Kurone's PoV)

The heels of my Mary Janes clicked a chaotic, halting rhythm against the freezing asphalt of the completely deserted suburban street.

Instead of walking like the confident girl who used to make the entire student body stop in their tracks, my steps were the uncertain stumble of a girl who no longer possessed a single destination in the world.

The harsh amber glow of the streetlamps overhead was a constant reminder of my loneliness in that moment, and every agonized step I forced my legs to take was pulling me further away from his front porch. Every step was dragging me back toward the cold, echoing reality of my own house.

I pulled the lapels of my rumpled school blazer tightly around my chest, and my small hands were shaking violently as I squeezed my arms together to hold back a rising sob.

'Why now?' The question clawed at my temples, fierce and suffocating. 'Why am I only feeling the weight of these emotions right now? Why does my chest feel like it's being crushed under a mountain, even though I am officially dating the most beautiful, popular, and desired boy in the entire school?'

Of course, there were no answers waiting for me in the dark. Perhaps the universe didn't owe an explanation to someone like me, or perhaps there were no answers at all—only the heavy, permanent consequences of the choices I had made with my own mouth and selfishness.

And God, I had chosen.

I had actively, deliberately chosen Kenji, preferring the superficial thrill of his flashy letterman jacket, the toxic rush of his public attention, and the cheap validation of being the girl at the arm of the alpha male everyone else wanted to claim.

I had chosen to sit in the leather passenger seat of his car, laughing softly as he cracked jokes about the pathetic, naive nature of the childhood pinky promise I had spent seven years using as a leash.

I had chosen to systematically violate Shin's trust, treating his absolute devotion like an invisible utility bill while he spent his lonely nights waiting for a text message I had zero intention of answering quickly.

And now, when my eyes had finally, tragically opened—when I finally wanted to look at him as a person—his dark eyes were already anchored entirely to another girl, someone who claimed to be my best friend.

'I clearly deserve this,' I thought, the realization settling into my bones like a bucket of freezing water, causing my teeth to chink together in the quiet street. 'I deserve every single ounce of this agonizing, suffocating isolation. I deserve to feel exactly this broken.' I kept thinking, my fists clenching involuntarily.

But even the logical acceptance of my own guilt didn't offer a single shred of comfort since it didn't soothe the burning ache behind my eyelids. It only made the reality of what I had witnessed a thousand times more lethal.

I kept walking, with my gaze locked on the ground, until I had finally arrived at my place.

My home was entirely silent when I finally stumbled through the grand entryway.

The towering ceilings and pristine marble floors felt less like a luxurious family villa and more like a cavernous, sterile mausoleum designed to amplify my own hollow reflection.

My parents had just gone away on another business trip to Europe, as they always were, and the household staff had long since retired to their private quarters for the night.

The entire house was nothing more than a magnificent, multi-million-yen shell overflowing with expensive foreign imports and high-end design, yet entirely devoid of human warmth, because, yes, my parents always gave me everything to justify their absence.

I dragged my feet up the sweeping, winding staircase, completely refusing to flip the light switches, moving through the familiar darkness like a literal ghost haunting her own past, until I pushed open the heavy wooden door to my bedroom, stepping into a space that was usually a monument to my perfection.

Designer clothes were meticulously organized behind custom glass closets; premium, sweet-scented cosmetics were aligned with mathematical precision across the lacquered vanity.

On the surface, it was a flawless life. Something that every normal person would surely envy.

But the moment my eyes scanned the dim room, my gaze was dragged inexorably to the small, empty space on my nightstand where the wrapped baking ingredients had sat.

The realization hit me like a physical blow to the stomach.

I had spent hours in the massive, quiet kitchen the night before, and even failed three separate times, with the delicate sugar burning into a bitter, black tar before I finally managed to achieve the exact, rich consistency of the artisanal caramel pastry.

I had scorched the skin of my fingers twice in my frantic haste, and even now, the tips of my index and middle fingers were still raw and tender, marked by small, red blisters.

I had endured the manual labor, the sweat, and the burning heat entirely for him—a pathetic, desperate attempt to hand him a physical apology he hadn't even asked for.

And he hadn't even looked at it, not for a single instant.

He didn't even touch the plastic container I had made with so much love.

Akane had simply reached out with her long, calloused fingers, snatched the box from my hands with a mocking, triumphant enthusiasm. I knew that she would've just thrown it away.

They had already forgotten it existed before my boots had even cleared their driveway.

Without even realizing it, a hot, heavy tear broke over my eyelashes, cutting a burning track through the dirt and sweat on my pale cheek, followed immediately by another.

My knees entirely gave out beneath the weight of my torso, and I collapsed onto the edge of my mattress.

As my head dropped into my hands, my tear-blurred vision happened to land on the dark, recessed corner of my walk-in closet.

Tucked away on the top shelf, half-concealed behind a row of designer winter coats, was a plain, weathered cardboard box that I hadn't reached for in years. I hadn't even thought about its existence since the beginning of high school.

'That box...' I thought.

I pushed myself off the bed, my bare feet moving silently over the plush rug as I crossed the room.

I reached into the closet, my fingertips catching the dusty edge of the cardboard, and pulled it down.

A fine layer of grey dust shifted through the air, settling onto the dark fabric of my uniform skirt.

'*Cough Cough* Ah... how much time has passed...?'

I sat down flat on the floor, crossing my legs, and pulled the top flaps open.

Inside that weathered box was the unvarnished, physical architecture of my past.

It was a dense collection of photographs, handwritten letters, festival tickets, and small, worthless trinkets that I had systematically holed away over a decade without ever truly understanding their value.

Those were all my shared memories with him.

I reached in with a trembling hand and pulled out the very first photograph from the pile.

It was a glossy, slightly faded picture of Shin and me at the neighborhood park playground where we were barely ten years old.

His dark hair was a messy, windswept disaster, his knees covered in sandbox dirt, but he was laughing directly into the camera lens, his eyes squeezed shut, in an expression of such pure, unadulterated happiness that it looked almost holy.

His small hand was wrapped around mine, holding on with a ferocious, protective strength.

I remembered that exact afternoon. I remembered the way he had stood on top of the wooden climbing structure, his tiny chest puffed out, looking down at me with absolute earnestness. "I'll protect you forever, Kuro! No matter what happens, I'll always be right here!" he had yelled into the wind, like a... white knight. A perfect white knight.

My lips curved into a small but broken smile as I remembered him.

Back then, the statement had seemed so incredibly naive to me.

It had felt like an annoying, clingy weight—a boring, predictable script spoken by a boy who didn't understand how the real world worked. But now... now the memory was a jagged, rusted iron spike being driven directly through the center of my ribcage.

I tossed the photo aside before my fingers dived deeper into the box to pull out another memory.

'This one...'

It was a snapshot from our school trip in the second year of middle school.

We were standing in front of a row of traditional festival stalls, and I was holding my wrist up to the camera to show off a cheap, gaudy bracelet made of wooden pearls.

Shin had spent his entire afternoon allowance at a local market stall just to buy that specific piece of junk for me because I had idly commented that the colors looked pretty.

As soon as the realization slammed into my brain with a sickening, cold clarity, I threw that photo away.

I remember that moment. I had tossed that bracelet into a public trash can three years ago because it wasn't branded, because it didn't look expensive enough to wear around the popular girls, because it didn't fit the image of the perfect angel I was trying to cultivate.

I had discarded his entire afternoon of sacrifice without a single second of thinking.

Then, I pulled out another photograph. It was from my fourteenth birthday, and the picture captured the exact moment Shin had handed me a massive bouquet of fresh pink roses, his face completely red with embarrassment, his eyes wide with the desperate, silent hope that he had done well.

In the photograph, my own smile was perfectly symmetrical, glossy, and completely hollow. I remembered what my brain had been doing during that exact second; I hadn't been thinking about his effort at all.

I had been staring at my phone under the table, waiting for a notification from an older high school boy, already planning how to slip away from Shin's company to attend a real party full of older people.

'Why... why did I do all of this?' I kept asking myself.

Then, I pulled out the very last photograph in the box: a Polaroid picture taken right in front of the main school building, precisely fourty-eight hours before the Valentine's Day massacre in the courtyard.

Shin didn't know anything yet. He was standing beside me, looking at the camera with that calm, gentle, reassuring smile that had been my safety net for seven years. I was smiling too, my arm hooked through his, but my mind had been entirely miles away, completely consumed by the secret text messages Kenji had been sending me from his locker.

'Why was this photo here...? Why?' I asked myself, before realization hit me. 'Right... this is... the trash box that I've never truly opened until now...'

The hot tears were pouring freely now, falling in heavy, silent drops onto the glossy surfaces of the old photographs, smudging the memories beneath the moisture.

'How could I?' I screamed silently into the empty room, my throat tightening until it felt raw. 'How could I have been so utterly, terrifyingly blind to what was standing right in front of my face?'

Shin had given me everything a human being could possibly offer another. He had given me his time, his absolute, undivided attention, his academic labor, and a constant, unbreakable devotion that wanted nothing in return.

And I... I had just taken, consuming his youth like a parasite, taking and taking without ever offering a single drop of real substance back. I had used his heart as a footstool to elevate my own status, all while snickering about his submissive nature behind his back with the athletic alpha who wanted to display me like a trophy.

"I... I think I finally understand," I whispered into the dark room, my voice breaking into a ragged, pathetic sob that sounded completely foreign to my ears. I reached down, my fingertips lightly brushing the image of our ten-year-old hands locked together in the park. "I finally see what you were giving me, Shin. But it's too late. It's so tragically too late."

I pressed the palm of my hand against my trembling mouth, my chest heaving violently as the full weight of my own actions completely crushed my remaining ego.

"The things I did behind your back... the systematic lies... they don't deserve a single drop of forgiveness, Shin. I know that now. I betrayed you so many times before Valentine's Day even arrived. My very first time... my first time with Kenji was that exact rainy afternoon last month, the day you walked me all the way home from school under your own umbrella, getting your own shoulders completely soaked just to keep me dry. Do you remember? You stood on my porch, your uniform dripping wet, looking at me with those honest eyes and telling me, 'I can't wait to see you again tomorrow, Kuro,' before wrapping me in an embrace that felt like you were terrified I would vanish from the earth if you let go."

A sharp, hysterical laugh escaped my throat, transforming into a heavy, gasping sob.

"I walked straight into his house after you left, ready to go to Kenji's bedroom. I didn't care that you would be devastated if you found out. I didn't care about your feelings at all. I was entirely blinded by the thrill, by the attention, by the shallow vanity of being desired by someone like him. And I only realized the true value of the person I was burning down now that I have permanently lost you to her."

I lowered my head until my forehead touched the dusty carpet between my knees, my tears soaking into the dark fabric of my uniform.

"People are utterly awful. The world is a disgusting, selfish place... and I am the absolute worst monster in it. I just hope... I hope with whatever pathetic shred of my soul is left that someday you will find it in your heart to forgive me. Or at least... I hope you realize the absolute sincerity of the feelings I am experiencing right now and the real love I am finally feeling for you now that you are completely out of my reach."

But even as the confession left my lips, the cynical, analytical part of my brain reminded me of the truth: it was a fantasy. Shin was never going to look back at me. Of course, he wasn't. Akane had already shaped him into the guy she always wanted, and I could feel that he was starting to experience feelings I'm never gonna feel.

I knew it. He had made his definitive, structural choice, and that choice was currently wrapped in his clothes inside his house.

I pushed myself off the floor, my mind entirely possessed by the toxic, looping images of what I had witnessed through the glass of his front door.

Akane.

I couldn't stop my brain from replaying the exact visual sequence of her standing in his entryway. She had looked so entirely, beautifully at home.

Her black, jagged hair was a wild, untamed mess around her pale face; her dark lips were visibly swollen and darkened, probably from the heavy intensity of his mouth.

Moreover, she had been wearing his plain, oversized black t-shirt, the cotton fabric swallowing her narrow frame and stopping dangerously midway down her bare thighs, making her long, toned legs completely exposed to the light.

She had passed the night in his bed, I knew it. She had slept against his chest.

And they had probably torn into each other beneath the duvet, sharing a physical and emotional catharsis that I had completely denied him for seven years because I wanted to keep him pure, because I wanted to keep him waiting like a faithful dog at the gate.

The thought pierced through my mind like a long, thin steel blade, turning my stomach into a knot of hot, violent revulsion.

I couldn't accept it. My entire system rejected the reality that Shin—My Shin—had made love to another woman. And not just any woman, but my former best friend.

Pain starts to wrap around my soul, swallowing me completely. I started breathing rapidly, and I could feel that I was about to pass out.

Panic was flowing through my veins, making me bolt out of my bedroom and run into the dark, expansive kitchen, my breathing coming in shallow, ragged gasps.

I immediately slapped the light switch above the central island, the bright, clinical fluorescent glow instantly illuminating the polished granite surface.

My eyes landed directly on the wooden cutting board resting near the sink. Sitting on top of it was a long, thin, razor-sharp utility knife—the Japanese steel blade I used every morning to precisely slice fruit for my diet.

Without thinking twice, I reached out and grabbed the handle, with my fingers locking around the cold hilt with a frantic, white-knuckled strength.

The weight of the steel felt heavy, solid, and terrifyingly real against my palm.

I immediately lifted the knife, bringing the silver edge of the blade directly against the pale, delicate skin of my left wrist, right over the blue veins that were pulsing violently with my erratic heartbeat.

'It would take just a moment, Kuro, and then it won't hurt anymore,' the dark, seductive whisper echoed in the hollow spaces of my mind.

Just a single, deep, decisive drag of the metal. A single cut. And the sharp, physical agony of the flesh would completely drown out the suffocating, unyielding blackness that is consuming my chest from the inside out. I could just make it stop.

I pressed the cold metal closer, the sharp tip of the blade indenting the surface of my skin, ready to pierce the barrier.

The tears were streaming continuously down my face, blurring the silver reflection of the steel into a hazy smear of light.

And then, right on the absolute precipice of the motion, a sound tore through the quiet kitchen.

"Kuro!"

It wasn't a real voice since there was no one in the massive, empty house with me.

That was a phantom memory, a vivid echo from the depths of my subconscious, exploding into my ears with the force of a physical gunshot.

It was Shin's voice. His old voice—the warm, breathless, frantic voice of the boy who used to run across the school courtyard, panting through his chest, his uniform unbuttoned, just to hand me an umbrella before the first drop of rain could touch my hair.

"Kuro, wait up! Don't go away yet! Just stay with me for a little while longer!"

The thin utility knife began to tremble violently in my right hand, the tip scratching the surface of my skin without cutting deep. My eyes widened in sudden, absolute terror as the illusion of his presence faded, leaving me alone under the harsh, buzzing fluorescent lights.

'What am I doing?' The thought slammed into my brain, cold and terrifying. 'What the hell am I actually doing right now?'

I let go of the handle as if the metal had suddenly turned into white-hot iron.

The knife clattered loudly against the granite counter, bouncing twice before coming to a rest near the sink.

Then, my entire body began to shake with a violent, uncontrollable tremor of pure adrenaline shock.

I scrambled backward away from the island, my spine hitting the opposite tiled wall of the kitchen with a heavy impact.

My legs completely gave out for the second time tonight, and I slid down the smooth surface of the wall until my bottom hit the cold floorboards.

Then, I buried my face into my knees, my hands locking behind my neck, and I finally let go of every single shred of my restraint.

I cried again. I wept without shame, without dignity, and without a single care for the pristine reputation I had spent my entire high school career building like a fortress.

Large, ugly, racking sob after sob tore out of my throat like wounded, feral animals, the raw sound echoing off the expensive marble and luxury appliances of the empty villa.

I knew that nobody would've come to help me, not even my 'servants'.

It wasn't fair. None of it was fair. The pain was too immense to hold inside.

But as the hysterics slowly began to empty my lungs, leaving me hollow and gasping for air against the kitchen tiles, the final, unyielding truth settled over my mind: it was my fault.

Every single drop of this misery was a product of my own hand. I had built my own execution stage and pulled the lever myself.

Then, during my outburst, a sudden, sharp vibration of my smartphone inside the pocket of my uniform blazer made me jump slightly, the mechanical buzz sounding incredibly loud in the echoing kitchen.

With slow, heavy movements, I reached into my pocket and pulled the device out.

The bright digital screen illuminated the semi-darkness around my knees, casting a harsh blue glow over my tear-streaked face. There was a single new text notification banner sitting across the lock screen.

'Kenji: Hey, Kuro. I just finished up with the guys at the arcade. Can I come over to your house tonight? My car is already down the street.'

I stared blankly at the words, the black letters dancing and blurring before my eyes through the remaining moisture of my tears.

Kenji. My popular and handsome alpha male for whom I had thrown away seven years of pure, unadulterated devotion, but at the same time, the boy who, during our entire relationship, had never once asked me how I felt, what I dreamed about, or why my eyes were sad, unless he was using the question as a tactical opening to get what he wanted between his sheets.

'What do I actually want from him right now?' I asked myself, my thumb hovering over the glass screen. 'What utility does he provide to a girl who is completely hollowed out?'

I didn't know. I didn't know a single thing anymore. The entire universe had turned into a chaotic, unreadable landscape.

My fingers lingered over the virtual keyboard for a long, agonizing minute, the blue light reflecting off my pale knuckles.

I thought about clicking his name and telling him to come over, letting him use his body to temporarily numb the agonizing blackness in my chest.

I thought about letting him hold me just so I wouldn't have to sit alone on the cold kitchen floor.

But then, the image of Shin's indifferent, flat face from the porch returned to my mind, and a sudden, heavy wave of pure exhaustion washed over me.

For some reason, I felt like making Kenji come here would be like cheating on Shin. This time, everything hit different.

Slowly, deliberately, I typed out my response.

'Kurone: Not tonight, Kenji. I'm really sorry. I'm not feeling well at all. I just need to be entirely alone tonight.'

I hit the send arrow, and the message bubble turned blue immediately.

Within three seconds, the small gray checks turned into the bright blue ticks of a read receipt.

Then, the three little pulsing dots of the "typing..." animation appeared at the bottom of the screen. My heart didn't even skip a beat. I just watched them oscillate.

Then... the dots vanished. The screen went completely static.

No response came. No follow-up question asking if I needed medicine. No message asking if he should drop off some food.

No expression of concern for the girl he supposedly loved.

He had read that I was sick, realized he wasn't going to get what he wanted tonight, and simply closed the app to drive home. I knew it, and I never cared until now.

Then, the phone slipped from my limp fingers, clattering onto the cold kitchen floorboards right beside my knee, the screen fading into absolute blackness after a few seconds.

The massive kitchen was entirely silent. The grand villa was silent. The entire suburban neighborhood outside the windows was quiet as a tomb.

I pulled my knees tighter against my chest, staring into the dark corner of the room, and the final reality of my existence settled over me like a heavy shroud.

I was alone. Completely, irrevocably, and permanently alone in the dark.
