【Goal】

Lock up Onii-chan.

“Why is it necessary?”

Lock up Onii-chan so that he can’t live without me. 』

….To all men. Have you ever had any experience of disgusted by a woman?

No, I don’t want to say it because I feel like I will make some enemies… So I’m asking if you have a experience of “being obsessed by the opposite sex”.

Don’t get me wrong, I don’t want to fight with you guys.

Therefore, this question doesn’t mean to incite you, and I don’t want to brag to an unspecified number of people. I want you to understand that.

Yes, this is not a boast, but a purely troublesome consultation.

I think my sister Akari Namiki is a charming girl. Excellent in studies, talented, and all-rounder in sports, if you compare her … Should I call her a perfect superhuman?

Especially, her appearance is outstanding. In other words, it is comparable to the level of TV idols. In fact, she seems to have called out several times, but she had no interest, thus she remains a beautiful ordinary person who never appeared on TV or in magazines.

And, well, it’s not worth mentioning. Of course, she’s quite popular in the school. It may be a little exaggerated, but it seems that there are actually some groups of her fan club.

As an older brother, I would like to kick their ass saying that they’re the real idiots. Because I think sometimes they are suspicious that I’m her boyfriend. I don’t know if it’s true or not. And I don’t think there’s any problem with them being so wrong.

She has no specific boyfriends at present. This is the information I heard from herself, so I’m pretty sure about that.

No, the phrase I heard is a bit misleading. I’ll omit it because it’s a bit long.

In other words, it’s enough if you understand that my sister is an idol of the school, and there’s no particular boyfriend at the moment.

On the other hand, her brother ——— I, Yusuke Namiki, is an ordinary boy.

It’s easy to think that if there is such a beautiful younger sister then the older brother will also be attractive, but please be assured that it’s not the case at all.

I’m an ordinary high school student who is mediocre in appearance, grades, sports and so on.

By the way, there is no specific girlfriend at present. The only status that can compete with my sister. No, even if we have the same lover, the meaning will change considerably depending on the brother and sister, but please do not touch that topic.

In other words, I’m a mob. Brother of a very popular sister. I am the boy who doesn’t have a specific girlfriend at the moment.

It proves that there is less to talk about me than my sister.

Well, why am I introducing my sister at this time?

It all started with an event two years ago.

I was in the third year of junior high school that was when I first learned about the existence of the ‘NOTEBOOK’.

I visited my sister’s room, where we had not exchanged any conversations for the past few years. I wanted to borrow a second-year textbook to study for the entrance exam. But since the owner was absent, I broke into the room without permission.

“If I borrow it secretly and return it later, it will be all right.”

“Geography’s textbook…There it is.”

I easily found the title ‘Geography’ from the neatly arranged textbooks.

Well, sometimes it is inconvenient for siblings.

It’s normal to exchange your textbooks with your siblings. But… It’s possible only for those siblings who are close as friends. However, it’s a completely different story with a disagreeable sibling like us.

“… Okay, let’s go back to the room.”

I got the target. After that, I have to hurry back to my room before my sister Akari returns home.

I don’t know what would happen if she finds out. It’s scary to think because I don’t really know what will happen.

And when I was trying to get out of the room….

“O, it hurts!”

I slammed my left leg’s little finger into the drawer.

“I never thought that the drawer was left open …”

I looked at the point where I hit my little finger, the bottom of a three-tiered drawer on the desk.

“… What? This drawer is kind of heavy.”

I tried to close the drawer as it is. However, it was extremely heavy. I think that a drawer usually closes by itself with a little effort, but … for some reason, it doesn’t budge.

I look inside the drawer. There are only a few paperbacks in it.

“What’s going on?”

I take out the paperback and touch the bottom.

When I pushed toward the front, I suddenly noticed that the bottom of the drawer was out of position.

I applied force to the front and lift the back. There was more space at the bottom of the board, and a large number of books were laid there.

“This is……?”

I took one of the notebooks, I saw the front cover of the book reads ‘Onii-chan Note 1’.

“Onii-chan Notebook?”* “TN: お兄ちゃんノート“

What is this, a novel, or something?

Akari’s older brother, that is, it’s me, but unfortunately, it’s hard to say that the relationship between me and Akari is good as a compliment.

It could be a novel or something like that. I think it is reasonable to think so.

“……. I’m worried. What should I do?”

My younger sister, Akari.

We were good friends when we were little, but by the time we became junior high school students, something like an invisible wall was formed and while living under the same roof, we became strangers. We no longer talk to each other.

A secret notebook that younger sister hides in such an elaborate way.

…… To be honest, it’s not strange to worry.

No matter what the contents were, it was so tightly hidden that it made me wonder if it was a notebook that would kill the person whose name was written.

This cannot be overlooked.

“I won’t let that happen.”

I was lost in my thoughts, but in the end, I lost my desire and decided to open the notebook.

“May 3rd, Tuesday.

Even though it’s a holiday, Onii-chan is going to school for club activities. I want to stay with Onii-chan for the rest of the day. But with club activities, it can’t be helped.

So today I decided to check my brother’s personal belongings.

…… Thanks to that, tonight’s affair has progressed a lot.

Onii-chan, I love you ♥️”

……..Hmm?

“May 25th, Wednesday.

My Onii-chan isn’t feeling well lately. I know the cause, it’s that woman.

On Monday, Onii-chan was dumped by a girl named Kato. There is no doubt because I confirmed it behind the scene.

“Sorry. I don’t hate Namiki-kun, but … I can only see you as a friend.”

…To be honest, I doubted my ears.

I can’t think of turning down my brother’s confession……

I should be happy that Onii-chan couldn’t date her, but when I saw his sad face, it became painful. What a complicated feeling.

…… But I also love such a sad expression of Onii-chan ♥️”

Hmm?

“September 27th, Tuesday.

Today is my birthday.

Well, I didn’t receive a gift from Onii-chan, but … This morning, he said ‘Congratulations’. I was so happy that I almost hugged Onii-chan….. Dangerous, it’s dangerous. My plan was about to become a water bubble.

Anyway, Onii-chan remembered my birthday…..

To be honest, I thought he forgot, I was so surprised that I was desperate to stop grinning my face all day long.

A classmate said, “Namiki-San, You seem to be in a very good mood today, something happened?”…….”

Bamm!

I read that far and closed the notebook vigorously.

I returned the notebook to the place where it was. As if nothing had happened. I corrected the drawer to the original place and left the room.

I returned to my room and dived in the futon. I suppressed the urge to scream and rolled around on the bed.

It’s no good.

Aaaaaaaaaaaaa! I read that much in momentum, but no matter what I think, it’s not a good read.

All that was written in the notebook was the very action I took a year ago.

I was certainly attending club activities during Golden Week, last May. In the same month, I remember being dumped by Kato-san.

And in September, on Akari’s birthday, there is no doubt that I said the word ‘congratulations’.

‘Onii-chan Notebook’ … In other words, it’s not a novel.

It is a genuine note about me.

“No… that’s a problem, but….”

But that’s not the point.

“Onii-chan, I love you ♥️”

I checked only a few pages. However, even on those few days worth of pages, all the closing sentences were unified in this one sentence.

Does Akari like me? And with a heart symbol …?

I still remember when Akari became a junior high school student, she told me with a cold look, “Don’t talk to me.”

It is the same at home and school. “I’m embarrassed to be teased by everyone around me……”

and there is no such thing as “I’m embarrassed outside, but you can talk to me inside the house …?”

It’s a mistake. If I remember correctly then she threatened me with an expression saying “I’ll kill you if you get close to me.”

Akari hates me.

I don’t hate Akari, but if the person in question tells me not to talk to her, then I have no choice. I’m sure Akari doesn’t like me. I don’t know the cause, but she hates having a conversation with me and It can’t be helped.

I thought so …..

“I’m back!”

When I was about to dive into my consciousness, I heard Akari’s voice from the downstairs.

Akari, are you back?

From the door that I left open, I can hear the voice of Akari and my mother. Every time I hear her voice, the notebook I read earlier crosses my mind, and I got confused.

Oh, if I hadn’t gone there to get a geography textbook, it wouldn’t be like this. A geography textbook?

“… No wait! I left the textbook on her desk because I was in a hurry!”

Before I entered the room, Akari’s desk was clean and tidy.

I don’t know if Akari always keeps that state. But if she notices a geography textbook on her desk that she doesn’t remember, she would be suspicious.

“I have to hurry to get it …!”

I move my body and head carefully to the room so that she won’t notice downstairs.

It’ll be okay if I hurry up. There’s still some time…..!

I gently open the door. As it is, I picked up the textbook with my sweaty hand and hurriedly escaped from the room.

…… It was dangerous. It would have been even worse if I had left it in the room.

“Yusuke, can you come down for a moment?”

When I was leaving Akari’s room, my mother from the downstairs called me. I was surprised by this sudden call. Please stop.

“I, I understand!”

But I can’t stay here forever.

I was called by my mother, so let’s put the textbook in my room and head down.

I hurried back to my room, put down the textbook and headed to the stairs.

And on the way down the stairs.

“Ah……”

I met Akari, who was climbing upstairs.

“Oh, um…Welcome home..?”

It is a scene where they pass by ignoring each other, but the recent incident comes in my mind, I suddenly spoke to Akari.

“……”

But as usual and naturally, Akari ignored me and went upstairs. She went straight into her room and shut the door without any sign of concern.

“You hate me…Isn’t it?”

In the notebook, Akari’s love for me was straightforward.

However, Akari’s image is quite the opposite.

What is true and what is false…

This was the first page of my troubles, born in my third year of junior high school, that continued to this day.
