Around 13.7 billion years ago, everything in the entire universe was condensed in an infinite-like small singularity, a point of infinite denseness and heat.

Suddenly, an explosive expansion began, ballooning our universe outwards faster than the speed of light.

This was a period of cosmic inflation that lasted mere fractions of a second.

The cosmic inflation came to a sudden and still-mysterious end.

A flood of matter and radiation, known as "reheating," began populating our universe with the stuff we know today: particles, atoms, the stuff that would become stars and galaxies, and so on.

…

"Hey, Is he alright?"

"I don't know. The teachers have been calling him or they shake his body and he still does not wake up."

"Do you think we need to call an ambulance?"

"That's so lame…"

What is this?

Why am I hearing voices?

Where am I?

I feel unwell but I open my eyes to see my surrounding.

"Oh! he woke up!"

"Yeah, it seems that he is okay, I'm relieved."

"That's so lame."

I slowly look up while wiping my eyes.

My vision is very blurry but it slowly becoming clear.

"Hey. You. You finally wake up. We're on the last subject. I just tell you so you could know."

"Hey, Ai. The way you said… is kinda tsundere. He might misunderstand it if you're like that."

!!!!

"What are you talking about?!!! Let's leave!"

"That's so lame."

In front of me are three girls.

I already expect it because of the voice but… for some reason… they are familiar…

"Hey, Itsuka-kun! Are you awake? Good."

Suddenly, a boy pats my back.

Itsuka-Kun?

Who's that?

He is looking at me.

I remember that those girls also called me like that.

I think that's my name but how?

After all, my name is—

Wait! now that I think about it.

Why am I in a classroom?

Did they release me from jail?

But… this place is different from what I remember.

How can I describe it…?

Hmmm… This place looks like a classroom in some suburban area.

Wait? How do I know this?

"Hey, Itsuka-Kun. Are you really okay? Why are you staring at me like that? Is there dirt on my face?"

The boy shows concern on his face.

What should I do?

I'm confused now and don't know what's going on.

All the students were looking at my position.

I feel like I'm going to throw up and I don't why.

I couldn't control it so I stand up and was about to walk out.

"Itsuka-Kun, where are you going? The class was about to… Itsuka-kun! hey, Itsuka-Kun!"

Before I go out, a woman opens the door and talks to me.

She look so young but from the way she spoke to me, I think she was supposed to be our teacher.

However, I felt like I was going to vomit soon so I passed her and ran.

In the quiet hallway, she shouted the name that was supposed to be mine.
