After My Girlfriend Dumped Me, I Got Reincarnated As A High School Student. That Part’s Fine—But Why Are All My Ex-Girlfriends Here Too? - Chapter 2 – There’s No Way I Have a Cute Little Sister

“Mm…”

The consciousness that should’ve vanished was slowly returning, awakened by the glow of a light seeping through my closed eyelids.

Right… I got hit by a truck, didn’t I?

So that means… I’m in a hospital?

No, that can’t be right. If you jump straight in front of a truck, you don’t wake up in a hospital—you die instantly.

Wait… why did I even jump in front of that truck?

〈You were pushed from behind.〉

A voice suddenly echoed in my head.

…Yeah, no. I’m just imagining things. Definitely just my imagination.

〈If this were your imagination, wouldn’t you think of something more pleasant? Running from reality isn’t healthy, you know.〉

What the hell—am I having a full-on conversation with my hallucination now!?

〈Anyway, it’s faster if you just see for yourself.〉

See what? I’m obviously lying in a hospital bed or something.

〈Then tell me—do you feel any pain right now?〉

“Huh?”

Now that they mentioned it… I didn’t feel any pain at all. With a hit like that, even surviving would mean broken bones or something. But I didn’t feel any cast, bandage, or even stiffness anywhere.

Wait, am I… completely fine? Immortal, maybe?

Sure, I looked young for my age—but my hairline had already started retreating, so that theory didn’t really hold up.

〈Why is that where your mind goes…? Anyway, open your eyes and see for yourself.〉

After that voice faded, my senses gradually sharpened.

I could hear footsteps approaching, faint voices in the distance, and then… a soft, fruity scent drifting closer.

“Big brother! How long are you going to sleep!?”

The voice rang out right beside me, so loud I instinctively jumped up.

(Oh, did you know? The word dai-onsei—actually it’s pronounced dai-onjō! Fun fact!)

…Not that it was the time for random trivia.

The room I woke up in wasn’t familiar at all. Not a hospital, but… it looked like an ordinary high school boy’s bedroom.

A study desk with zero school supplies. A bookshelf crammed with manga. A TV and a gaming console stacked on a small rack.

Sure, it looked like the kind of room I’d have liked, but I had no memory of it whatsoever.

Where… am I?

“Hey, big brother? Are you just going to sit there spacing out?”

And more importantly— in the real world, I didn’t have a cute little sister who called me “big brother” in such a sweet voice.

Yeah, no way.

I did have a younger brother, but he wasn’t cute in the slightest. He stopped calling me “bro” ages ago—these days it’s just “hey” or “you.”

Well… I guess it’d be creepy if a grown man was cute.

Anyway—the “little sister” in front of me looked oddly familiar.

“Hii-chan…?”

Her name was Hinami Oishi. Light brown short hair that reached her neck, black-rimmed glasses, and a height around my shoulder. She might’ve looked plain at first glance, but her personality was bright and energetic.

She was two years younger than me—we’d met in the same vocational school, and she’d quickly become my closest junior. Even after graduation, we kept in touch, and somewhere along the way, she started calling me big brother “because you feel like family.”

“Stop daydreaming and get ready! You’ll be late for school!”

“School…?”

I stared at her blankly. Hii-chan was wearing a uniform I’d never seen before—a sailor-style outfit with red-and-blue checkered ribbons at the collar, a white blouse, and a skirt of matching plaid.

Her legs stretched out from beneath the pleats—smooth, healthy, and distractingly pretty—

“…Big brother?”

I’d looked too long. She glared at me, flustered, tugging nervously at her skirt hem.

“A-ahaha… sorry, sorry…”

I mean, come on—she looked adorable in that uniform!

“Uh, wait. Who… exactly am I?”

That was the real question.

For all I knew, I could be dead—and somehow swapped into someone else’s body or something.
…Yeah, okay, that only happens in manga, but still.

“B-big brother? Don’t tell me… y-you’ve lost your memory!? Mom! MOM! Big brother’s—!”

“Wait, wait! Hold on!”

I reached out to stop her as she rushed toward the door, but lost my balance. We both tumbled back—

“Uwah!”
“Kya!”

—and fell onto the bed together.

Somehow, I ended up on top of her.

“Eh… u-um…”

Her face turned crimson as our eyes met up close.

“I—I’m sorry, I didn’t mean—”

“What are you two—?!”

The door suddenly swung open, revealing a woman I recognized immediately.

My mother—Yurika Misumi. The same as in the real world.

She took one look at us, paused… and silently closed the door.

“No—wait! It’s not what it looks like!”

“Geez! Get off me already!”

Hinami shoved me off, her face still bright red, and bolted out of the room.

“Wait—Hii-chan! …She’s gone.”

“My, my. You’re awfully lively for someone who just came back from the dead.”

The familiar voice I’d heard in my head earlier now spoke out loud—close by.

“Wh-where are you!?”

“Up we go.”

I looked around wildly—and then, from the desk drawer, something poked its head out.

It climbed out completely, landing softly on the floor—Just like a certain famous blue, cat-shaped robot.
