You Have to Survive, Miya-kun

[A new upcoming Haikyuu!! stock-picking romance to check out: How Is My AI Boyfriend a Real Person?! It was supposed to be an AI, but the person on the other end is actually real?]

Spacey, oblivious, slightly sadistic, blunt girl x Osamu, a snarky guy always trying to take back the initiative

Bassist x setter

Main Story Blurb

Uchiumi Iri realized she was living inside a manga.

Though she knew nothing about the plot or setting, she had plenty of experience reading manga.

It didn't take her long to spot a classic manga trope in one of her classmates: twins.

Twins aren't anything unusual, considering how many pairs there are in the world.

But this pair fit all the conditions for the familiar manga trope of the twins' curse.

And all the ominous traits were concentrated in one person. It seemed someone was destined to be sacrificed.

Sensing that the moment was drawing near, she decided to give the victim a hint about the plot:

"You have to survive, Miya."

"Huh?"

When Uchiumi first met him, she never would have imagined that just two months later, they would be dating.

If she'd known that one kind reminder from her would lead to such a tragic disaster, she never would have cared whether he lived or died.

But two months later, Uchiumi was saying:

"Osamu, want to hold hands?"

"Osamu, bend your head down a little."

"Osamu, give me a hug."

You know, besides being handsome and having flashy volleyball skills, this guy has plenty of flaws that are hard to ignore. He's a sore loser, stubborn, does whatever he wants, and can be surprisingly timid at times.

But that's okay, because he can't escape her clutches.

"Besides, aren't those flaws all pretty cute?"

Uchiumi, who sat in front of him, was a strange person.

She did strange things.

She said strange things, too.

But somewhere along the way,

he became strange as well.

1. Pairing: Inarizaki's setter, one-on-one.

2. No secondary couples. Everyone besides the main couple is just friends.

3. The main story is a school romance comedy, spanning from the first year of high school to after graduation.

(Heroine's flashback side story, early band-activity side story, and a later hidden career storyline.)

[Most likely my next book]

You're a miserable office worker who gets hit by a truck on your way to an exam.

No matter what you do, you always fall just short. That label sticks with you until the day you die.

Even during your short, mediocre life, you had dreams.

Back in high school, you'd sneak your phone out of school during your half-day weekend break, crouch in the milk tea shop by the back gate, and use their Wi-Fi to watch anime. Seeing the characters on screen, students like you but living such vibrant youth, you unconsciously made a wish:

"In my next life, let me be a high school boy in a neon-lit city."

That was the last thing that flashed through your mind before you died at twenty-two.

Not one of life's ten great regrets, nor the companionship of your family and friends. Of all things...

It was this ridiculous daydream.

Your brain really has been ruined by reading fanfiction.

But when you opened your eyes again, your dream had come true.

!

If only you'd asked to be a high school girl! You still wanted to be a girl!

You instinctively lifted the covers...

Thank goodness, nothing strange had grown there.

Reincarnation, huge success

Right?

A spherical object claiming to be the System dropped from the sky. It told you there was no such thing as a free lunch, and reincarnation came at a price.

You were now a bona fide Tokyo city girl, but if you wanted to keep living as you were, you'd have to fill in the missing details of your character setting yourself.

Your wish had been partly fulfilled. Now it was time to "pay the price"!

With that, it yelled something about dreams, bonds, pillars, and winning the national championship, then charged straight at your face

You died again.

Your brief trial period as a high school girl expired. When you woke up again, you had become someone else.

Feeling uneasy, you lifted the covers...

Oh crap!

"I don't want to live anymore!"

After several breakdowns, you finally cried out.

A flurry of footsteps approached, and the bedroom door swung open. A burly, bearded man with his chest bared rushed in:

"Hey, brat, what's going on?!"

A friendly reminder: Your current swap partner is Echizen Ryoma, a first-year student at Seishun Academy.

Your first violation will not count toward the total and will be exempt from punishment.

If the same swap assignment is found to have violated the rules more than three times, the swap will fail, and all completed character settings will be discarded.

Settings reset. Reincarnation failed.

There is exactly one rule for all swap assignments.

No OOC.

1. The victims of the swaps won't disappear. To protect their right to an education, "he" will keep going to school in your body.

2. Swaps have a time limit. You'll switch back at important moments. That's what you get for not learning superpowered tennis.

3. You don't need to keep the swaps secret. Go ahead and tell people if you think they'll believe you.

4. The System reserves the final right to interpret these rules.

Theme: Someone will always love your imperfections
