You ever hear the saying, "Life is a movie, and you're the main character"?
Yeah… mine was more like one of those low-budget indie films nobody watches.
Wake up, go to work, eat, sleep, repeat. No romance. No epic adventures. Just… existing.
I wasn't a hero, I wasn't a genius, and I definitely wasn't rich. I was just me.
A 23-year-old office drone who spent more time reading manga and watching anime than actually talking to people.
Funny thing is, I didn't even hate it.
Sure, my boss was a walking migraine in human form, and my paycheck was allergic to staying in my bank account, but… I thought I had time.
Time to maybe change things, find love, do something worth remembering.
Turns out, the universe had other plans.
One rainy night, I was walking home, umbrella in one hand, convenience store ramen in the other, thinking about whether to start another isekai novel.
And then—BAM. Headlights. Screeching tires.
Cliché? Absolutely.
The only twist was… I didn't wake up in a hospital.
At least, not the way I expected.
There was a strange heaviness, like my body was wrapped in wet cloth. My limbs felt stubby, my movements clumsy and uncoordinated. My voice—when I tried to speak—came out as a squeaky cry.
Then… light.
Blinding at first, until my eyes adjusted, and I saw her.
A young woman with silky hair that shimmered under the hospital lights, and eyes—no, stars.
Not the metaphorical kind. Literally, her irises glittered like a galaxy. She was looking at me with the kind of warmth I'd only ever read about.
Next to me, swaddled in soft blankets, was another tiny human. A baby girl with the same starry eyes, though hers blinked curiously like she was trying to figure out what planet she'd landed on.
We weren't just two newborns sharing a bassinet.
We were twins.
"Congratulations, Ai-chan," a nurse said cheerfully.
Ai.
The name hit me like ice water down the spine. My sluggish mind connected the dots, every late-night anime binge and spoiler I'd half-ignored coming back to me in an instant.
Ai Hoshino. Rising idol. National sweetheart. And… doomed.
If this was that Ai Hoshino, then my sister would be Ruby. And that meant—oh, fantastic. I was in Oshi no Ko.
And I had been reborn as Aquamarine Hoshino.
Aquamarine.
That was my name now. If that hadn't rung any bells for my ex-anime-addict self, the next few days had. Every little detail slotted into place like a puzzle I didn't want to finish.
Right now, I sat in our modest living room, a spoon in my hand, eating porridge while observing the chaos in front of me.
"Say ahh," said a pretty purple-haired teenage girl, holding a spoonful of food toward a toddler with blonde hair and—of course—star-filled eyes.
"Ahh," Ruby replied obediently, chomping down like it was the best thing she'd ever eaten.
Though I say "little girl," there was a big contrast between the two's ages.
The purple-haired one—Kana Arima, child actress extraordinaire, if my memory was right—was about sixteen. The blonde-haired one was my dear twin sister.
And the mother of said toddlers? None other than Ai Hoshino.
My mother.
Don't ask me why my mother is sixteen.
What a mess.
Japan was crazy for things like this. I used to like the culture back when I was still a youngling in my old life, but over time, I realized the harsh truth. And now, living in the middle of that truth? Yeah, it hit home.
"Aqua."
I looked up to see Ai turning her gaze toward me. Her eyes softened, tilting her head in that effortless idol way that made fans across the country melt.
"What's wrong? Do you want me to feed you too?"
I was once again reminded—painfully—that my new name was Aquamarine Hoshino. Dammit.
Unwilling to cause her trouble, I just shook my little head, lifted the spoon myself, and ate.
"Aww." Ai's smile widened. "I'm still surprised how you can do that at this age. My little genius. Must be genetics, huh?"
I ignored her adoration. And the jealous glare of the other toddler.
That toddler girl was my twin. She was also a reincarnator herself—someone who'd been a normal human in her past life. I hadn't exactly introduced myself to her in that sense, but… I could tell.
It was in the way she observed things, the occasional too-mature flicker in her gaze, the way she processed the world. And the way she seemed to realize I wasn't just "another baby" from day one.
Still, she was… bothersome.
Ruby narrowed her eyes at me like I'd just stolen her favorite toy.
I could practically hear her inner voice screaming, "That's MY mom's praise, you glorified soup slurper!"
She didn't know I could see through her that easily.
She didn't know a lot of things.
Like how I knew her other identity.
Or how I already suspected she'd try something petty to assert dominance in this toddler war she was waging.
But fine. She could keep glaring. I had bigger things to deal with.
Because just as I was about to take another spoonful of porridge, it happened.
Ding.
Soft, like a phone notification heard from across the room, but somehow it echoed inside my skull. My spoon froze mid-air.
Then—

…What.
In my old life, I'd read enough fanfiction to know exactly what this looked like.
A system.
My system.
And not just any system—a Multiverse Chat Group.
Before I could even wrap my head around it, more notifications appeared.
My baby brain might've been underdeveloped, but my twenty-three-year-old mind was already screaming in excitement and panic.
This wasn't just a cheat. This was a golden ticket to rewrite everything.
Including Ai's fate.
