I’m Back in the First Grade of Elementary School, so I’m Going to Live Well

Mizui Lodging

In the world of anime and manga, there is often a scene where you wake up in the morning to find a girl sleeping next to you.

It’s a scene that has been used so much that it could be called a cliché.

Yet, the scene is still used in various works.

This is because there is a certain romance in it.

That’s right, there is a man’s romance.

Waking up in the morning to find a girl lying next to you unprotected.

What could be more blissful for a man in this world than that?

There is no such thing. And it can’t happen in reality.

It is only a fictional story. It is a story that can only be realized in fantasy.

It’s impossible, and that’s why it’s so romantic.

That’s a well-known fact, and I understand it.

――However, I have to admit that it actually happened.

It was the early morning of the next day after Mizui-san’s visit.

Mizui-san is sleeping next to me.

Even if I rub my eyes to check, or even if I look away once and then look again, I am sure that Mizui-san is there in her pajamas.

This is the moment when fiction becomes reality.

It might have been a reasonable reaction to be happy or confused, but I remained calm.

Compared to Mizui-san’s past actions (such as following me around), it was a cute thing.

In fact, she’s cute in her sleep……

Oops, I don’t mean cute like that. I mean it’s not important.

Anyway, I’m not the kind of guy who gets upset over something like this.

But it’s not a good idea to lie in the same bed with a girl, so let’s just get off the bed.

So I thought, and when I crossed over Mizui-san to get off the bed, I covered her for a moment.

“Sho, it’s time to get up――”

It was the moment when, from the side, it looked like I was straddling Mizui-san.

My mother entered the room at the worst possible time, as if she had planned it.

And it was only at a time like this that she forgot to knock.

“…… you can’t be doing that in elementary school…”

“No, it’s a misunderstanding!”

My mother’s expression tightened, and I did my best to deny it.

…… Well, this is the way it always goes, isn’t it?

◆

Seven o’clock in the morning.

The whole family and Mizui-san woke up and had breakfast on the table.

“…… Sho …… Don’t do anything to assault Mizui-chan.”

“Buh-oh!”

You’re saying that in a situation where Mizui-san is right in front of you, of all people, Mom?

“No, no, no! That was Mizui-san getting into my bed.”

“What kind of girl walks into a bed where a man is sleeping unprotected?”

“Guh!”

My sister’s point is wrong.

I’m sure that Mizui-san was sleeping next to me, even if I’m not sure why.

Of course, I didn’t move her, and she may have just been sleepwalking, but I’m pretty sure she came into my bed voluntarily.

However, my sister was right, such girls are not common.

Even though she is a first grade girl who has not yet entered puberty, she should be able to understand such things.

So, I can’t argue with it.

My testimony alone is not credible.

“Even if you’re old enough to be interested in girls, there are good and bad things to do.”

“No, no, no, Dad!”

Even my father had become my enemy.

It was the right decision for a child who had done something wrong, but I wanted him to listen to me, the eldest son, a little.

I lowered my shoulders that there was no one to listen to me anymore.

“I don’t care what Sho-kun does to me……”

““““Huh!?””””

The entire Itosaki family was shocked by the shocking words of Mizui-san with blushing cheeks.

It was a lively breakfast scene of the Itosaki family.

◆

“Sho-kun, what are you doing?”

It was 1:30 in the afternoon.

Mizui-san, who had finished lunch and was helping mother wash the dishes, had finished her task and came into my room.

“I’m studying.”

But I’m studying for junior high school.

Just because your friends are coming to visit you doesn’t mean that you can just sit around and play.

You have to put a lot of study into your mind when you are a child.

Being able to study is a prerequisite for getting a job that is worth it in the future.

You can’t have a regular job without studying.

This is a lesson I learned in my first life.

“Hee, you’re a hard worker.”

“No, not really.”

I’m happy when people praise me honestly.

But if my friends are visiting me in my room, I feel bad about studying alone.

I only started studying because she was helping my mother and I’m too lazy to do anything else.

It was fine for me to be idle, but it was not fine for my guest, Mizui-san, to be idle.

I put down my pencil and tried to close the textbook.

“Ah, here.”

“Hmm?”

Mizui-san pointed to a problem before I could close it.

It’s a linear equation problem that I learned in first grade.

It’s a problem I’ve already solved, but what the heck is wrong with that?

“You’re doing the math wrong here. x = 3 here.”

“What?”

I review the problem.

It’s really wrong.

“H-How did you know?”

Even if it is a simple calculation error, it is not an easy problem to solve.

“It had instructions on how to solve the problem.”

This textbook contains both the solution and the problem on a single page spread, one on the left half and the other on the right half.

It’s true that even if you don’t know the problem, you can understand how to solve a linear equation by looking at this page.

But she looked at the page for less than ten seconds.

How can she read, understand, and refer to the answers to the problems I solved and her own in such a short time?

“You’ll know the answers to most of them when you see how to solve them.”

“……”

I was stunned.

Natural intelligence. A natural-born genius.

I really envy her.
