The Gender-Reversal Boom Is Coming...!

The gunshot rang out like a thunderclap.

That was my last will and testament.

Everything went dark in an instant. My vision blurred, and the world spun as if I'd been sucked into a black hole. The last thing I felt was the cold bite of the floor against my cheek, followed by the metallic tang of blood flooding my mouth.

Then, nothing.

When I opened my eyes again, I wasn't in some afterlife or staring down at my own corpse from above. Instead, I found myself standing in the middle of a vast, empty white space. Like a blank canvas with no edges. No floor, no ceiling—just endless, blinding white.

What the hell? Is this the isekai starter pack? Did I really get reincarnated after getting shot?

I patted myself down. Arms, legs, torso—all intact. No bullet holes. My body felt strangely light, almost weightless. And my clothes... they were the same ratty hoodie and jeans I'd been wearing when that bastard pulled the trigger.

Before I could spiral any further, a translucent blue window materialized right in front of my face. It shimmered like a holographic display, complete with that classic system notification chime echoing in my skull.

I blinked. Then blinked again. The words didn't change.

"Gender reversal? Matriarchal society? What kind of bullshit is this?"

My voice came out higher than usual. Smoother. Almost... cute? I looked down at my hands. They were smaller, more delicate. My arms were thinner, my shoulders narrower. A cold sweat broke out across my forehead as I reached up to touch my face—only to freeze when my fingers brushed against long, silky hair that definitely hadn't been there before.

No. No way. This can't be happening.

I frantically patted my chest. Flat. Then lower—

"Holy shit, it's gone!"

My scream echoed through the white void. The system window flickered, as if amused, before a new message popped up.

The window dissolved into particles of light, leaving me standing there in stunned silence. My legs gave out, and I collapsed onto the invisible floor. Or maybe it was just more white space. Who the hell knew anymore?

"This has to be a dream. Or a prank. Or some kind of elaborate revenge from that loan shark I owed money to..."

But even as I said it, I knew it wasn't true. The sensation of my new body was too real. The way my hair kept falling into my eyes, the unfamiliar lightness in my chest, the complete and utter absence of my former pride and joy between my legs—it was all too visceral to be fake.

A soft chuckle echoed from somewhere behind me. I whipped around, heart pounding, only to find a ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠figure materializing out of the white. She looked like a goddess ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠straight out of a fantasy novel—flowing silver hair, eyes like molten gold, and an aura that screamed I'm way too OP for this tutorial level.

"Interesting reaction," she said, her voice like wind chimes mixed with pure mischief. "Most people cry or beg for their old lives back. You just sat there fondling yourself. Bold choice."

"Who the hell are you?" I snapped, scrambling to my feet. My voice cracked halfway through, sounding far too much like an angry kitten for my liking.

The goddess smiled, tilting her head. "Call me whatever you want. The Goddess of Gacha, perhaps? Or just your friendly neighborhood system admin. I've been watching you for a while, Kim Yona. Or should I say... the guy who spent his entire paycheck on limited-time banners and then cried about it on anonymous forums?"

My face burned. "That was one time!"

"It was thirty-seven times. I counted."

She waved her hand, and another window appeared—this one framed in glittering gold, like a premium gacha reward screen.

The goddess winked. "Consider it a welcome present. In this world, everything runs on gacha mechanics. Skills, items, relationships—even fate itself. Pull wisely, or you'll end up as some noble lady's plaything before you can say 'reroll'."

She began to fade, her form dissolving into sparkles. "Oh, and one last thing. The gender reversal boom is coming. Whether you ride the wave or get crushed under it... that's entirely up to you, new girl."

"Wait! What does that even mean? Hey!"

But she was already gone. The white space around me started to crack and shatter like breaking glass. Colors and shapes flooded in—stone walls, flickering torchlight, the distant roar of a crowd. I felt my body being pulled downward, as if falling through the floor.

The last thing I saw before everything went black again was my own reflection in a shattered piece of the white space. A girl with sharp eyes, messy black hair, and a look of pure, unfiltered panic stared back at me.

Kim Yona.

That's my name now.

When I came to, I was lying in a narrow alley somewhere in what looked like a medieval fantasy city. The air smelled of sweat, steel, and something sweet—like mana or magic or whatever the hell they called it here. My head throbbed, and my new, smaller body felt sore all over.

I pushed myself up, only to realize my hoodie had been replaced with a simple tunic and shorts that did very little to hide my new figure. A rusty dagger lay beside me, along with a small pouch that clinked with coins.

Before I could process any of it, another system window popped up, this time with a quest marker glowing in the corner.

I stared at it for a long moment. Then I laughed. It started as a small chuckle and quickly turned into full-blown, hysterical laughter that echoed off the alley walls.

"Gender reversal boom, huh?"

I picked up the dagger, twirling it awkwardly in my unfamiliar grip. My reflection in the blade showed that same panicked girl from before—but this time, there was a spark of something else in her eyes. Something reckless. Something that looked a lot like the old me.

"Fine. Bring it on, you crazy world."

I stood up, brushing the dirt off my new clothes.

"This gacha addict is about to speedrun your entire matriarchal ass."
