[TL: So Author had this as the final chapter and then made the side story (2nd year arc) longer than the first year arc. So I’m calling this a what if ending/side story.]

A completely white world.

Clothes, desks, chairs—everything was dyed pure white.

Within it, I handled the attacks of the boy in front of me… White Room 5th Generation A-Class, Takuya, with one hand.

“Damn it… Kiyotakaaaaa!!”

“Putting spirit into it is fine, but you’re tensing up too much.”

I slipped behind him and locked his arm.

“Guh!”

“That’s enough!”

At the command of Ichika, a red-haired girl also from White Room 5th Generation A-Class, I released him and took distance.

But there was no way Takuya would stop. He turned immediately and came in for a follow-up attack.

I had no obligation to take it, so I dodged and countered with a right fist to his jaw.

His brain rattled and he lost consciousness.

“Oops.”

I caught him before he collapsed and laid him on the floor.

“He never learns, does he?”

“He attacks me whenever he gets the chance. I’m used to it now.”

“You really have no openings, Kiyotaka-sama. As expected of the White Room’s masterpiece.”

I’d told her many times to stop calling me that, but Ichika never listened.

After returning to the White Room, I was given three roles.

First, just like before, I continued the highest difficulty beta curriculum.

It was for data collection. I’d done it before entering Advanced Nurturing High School, so it wasn’t an issue.

Second, while still a subject, I assisted the researchers.

I now spoke with people like Suzukake, Ishida, Sōya and Tabuchi.

And lastly, I acted as a teacher for later generations.

I trained Ichika, Takuya and the others, teaching them skills and knowledge.

The hardest part was that many of them, like Takuya, held hostility toward me.

Apparently, to raise competitiveness, my scores were shown to nearly all lower generations, telling them to become like Ayanokōji Kiyotaka.

No wonder they hated me.

On the other hand, a few, like Ichika, worshipped me.

Most of them lacked ability and were eliminated. Ichika was an exception—very talented, though still inferior to Takuya.

Excluding me, Takuya might be the best current White Room student.

Even so, he’s no match for me.

Hatred grows stronger in those who hate me.

Worship deepens in those who admire me.

It’s exhausting.

“Are you tired, Kiyotaka-sama?”

“No. Ichika, do you need guidance?”

“Hmm… sex education? Practically.”

She clung to me, pressing her chest against me.

Move.

“You’re a hundred years too early.”

“Then I’d be a grandma!”

“In other words, no.”

“You’re so mean.”

I left them and exited through the staff-only door.

“Again with Takuya and Ichika?”

“Suzukake. Yeah, same as always.”

He laughed irresponsibly.

“Your class system idea improved results. Aren’t you in danger?”

After I returned, the White Room system changed.

Inspired by school, I proposed class divisions based on ability.

Top classes get harder curriculum, lower ones drop instead of being eliminated.

With A–C classes, fewer students were expelled entirely.

Maybe Yuki would’ve survived with this system.

“You won’t lose?”

“Impossible. Even if heaven and earth reversed.”

He called me abnormal.

A product of the White Room… or natural talent.

Probably both.

After talking, I returned to my empty room.

A colorless room.

Nothing Chiaki had colored remained.

I lay on the bed.

Clean sheets.

Life here isn’t bad.

I’ve always lived here.

That one year was abnormal.

And yet… those vivid days won’t leave me.

My heart used to be white.

That year colored it.

At the center was—

‘…Am I regretting it?’

I remembered Kushida’s words.

So this is regret.

I want to see Chiaki.

Hold her.

…Kill that man?

He’s unguarded here.

No bodyguards.

White Room students are nothing to me.

My mind cooled.

Just tighten his neck.

I stood—

‘Kiyotaka-kun’

Chiaki’s face appeared.

I stopped.

If I kill… she won’t smile at me anymore.

* * *

Two years passed.

Empty days.

Training, attacks, temptation, sleep.

Yet I couldn’t forget.

“Kiyotaka-sama, are you okay?”

Ichika again.

“I’m fine.”

“I can see everything.”

She teased again.

Sex education.

I pushed her away.

She left laughing.

…Chiaki.

She’s probably moved on.

Even so, I won’t.

Eventually, that man will assign me a woman.

Until then, I’ll remember only Chiaki.

Two years passed.

Still, I remembered everything vividly.

“Someone wants to meet you.”

Suzukake led me.

“New staff. Help them.”

Not a breeding assignment.

…Relief?

“Go in.”

I entered.

The white room gained color.

“Kiyotaka-kun.”

The voice I wanted.

The face I wanted.

Chiaki stood there, slightly more mature.

“Chiaki…”

“Kiyotaka-kun!!”

She hugged me.

“I missed you!”

“I… missed you too.”

“How are you here?”

“We graduated Class A.”

She handed me a black case.

Graduation Certificate – Advanced Nurturing High School – Class A

“…The privilege?”

Graduate from Class A = guaranteed future path.

“…Sakayanagi’s father.”

“You’re amazing.”

She explained everything.

She changed her career path—

“To follow you.”

Even challenging the chairman.

Even competing with Sakayanagi.

And she won.

* * *

“…You used that privilege just to see me?”

“Yes.”

“Why? I rejected you.”

“I understood your message.”

Ending the contract meant—you loved me.

“…I tried to push you away.”

“But we met again.”

“What if I was serious?”

“Then I’d make you fall for me.”

…I smiled.

“You’re surprisingly stupid, Chiaki.”

“You’re the idiot.”

“…I lost. Thank you.”

I leaned in—

“Wait. We’re not dating.”

“Then?”

“Let’s start over. From the beginning.”

She understood.

I held her shoulders.

“I like you, Matsushita. Go out with me.”

“…Yes!”

No matter what obstacles come—we’ll face them together.

In the white room, we started again.

This time, there’s no end.
