"My school life is boring~♪ It's boring, but Nii-san is here, so I attend the school~♪ I want it to end quickly and be after school I wish this bastard~♪ Let me flirt quickly damn it~♪"

"What like an idiot are you doing singing a song that seems like you are just weaving everything together."

I turned my gaze as if saying, "like an idiot, you say, that's cruel."

Who was there was Toumei Rikka, an acquaintance of mine from middle school, who is just an acquaintance, and someone I'm not that close to either......Rikka seems to recognize me as a friend, but this girl also had a time when she shunned me when we were in middle school......That's why, try as I might, it was difficult to trust with all my heart.

"I think it's a good song though~ So Rikka didn't like it, huh~"

Even though it's a song that is filled with so much of my feelings for Nii-san~.

As evidence of that, the lightly floating cheerful Mashiro, as if imitating me, is humming my song and looks to be in a good mood anyway see.

"This girl, when she sings at karaoke, she's as good as a pro, and yet......only the talent of writing lyrics, in a way, is a discovery of the nonexistent."

"Ha? You mean to add miserliness to the lyrics I just made?"

"......I apologies. So please don't put on that face."

As if I were a murderer, I ended up scaring her.

I do have just a little self-awareness of it, so that was rude of me, though I don't think things like that either.....U~n, after all, although we've been acquaintances since before, it feels different from talking to Misora-senpai or Yuika-senpai.

(Those people are just that special riight. Though it's a convenient way of thinking that they absolutely won't do anything bad against us, but......aah gee, is it fine to be honestly happy? I came not to know it anymore.)

I do think that the fact that I've become friends with those two certainly makes me happy.

But is that pure happiness? Or am I happy because it's convenient for me? I so don't understand that I feel a bit complicated.

"Chisome think too hard and too difficult, just be honest and happy is fine." (Mashiro)

"......You're right"

Yareyare (good grief) No way, to think that the day would come when I would be admonished by Mashiro...... Uun, that has happened many times before, I think.

She looks like she's just softly floating around being frivolous, but in actuality she thinks of me and also Nii-san, a kind girl she is......This girl has really become splendid.

"You've been looking at the ceiling since a while back; what's wrong?"

"Uun, it's nothing."

If it were a little while ago, I thought that even this kind of exchange would become irritating, but the reason why it became not so anymore is none other than because peace of mind has been born within me.

That's why, I could say it with confidence――The me now is very happy.

(What to do after school today I wonder~......)

As for meeting up with Nii-san, it is as usual, but I'm in the mood for a little shopping.

No matter how much I can't meet Nii-san, if I were to think of Nii-san, my heart is fulfilled, and naturally ends up making me smile.

This expression makes a fool misunderstand and often calls out to me though, and I come to want to shout out, "No one's looking at you anyway."

"......Being popular is also something that requires thought isn't it~."

"You're saying it, aren't you. Well, since that's exactly right, I'm convinced of it too, though."

To say that's exactly right and let me have her understanding Rikka is a good girl, you know?

Rikka knows the thing about me going out with Nii-san anyway, and in the classroom or somewhere, I often talk about my love affairs with Nii-san......But still, there is a man who calls out to me.

"Chisome-san, is it fine for a bit?"

"What?"

The one who came and called out to me was a boy in the same class.

I can somehow make predictions, but even if I reject him strangely, the impression will become bad, so I try to just ask about what he needs.

"I don't mind either now anyway; can I have a little time after school?"

"It's fine here. Come on, say it quickly."

"......Uhh, that is――"

Withdrawing my previous statement, this might still normally give a bad impression.

However, I basically didn't take an act as if making the other girls an enemy anyway. I said it before, too; perhaps because I speak of my love for Nii-san in an easy-to-understand manner, there is almost no hostility pointed at me from students of the same sex, so this exchange was unexpectedly seen as funny and comical.

"......Please, Rikudou-san. It's a bit unreasonable to be in a public place."

"Is that what you call it's impossible unless it's just the two of us thing?"

"Yo-, You're right."

To him, he probably didn't think I was the type to speak bluntly this much, I guess.

I understand the thing about me being flashy compared to normal girls anyway, and I'm also aware that the way I talk is somewhat gyaru-like too, so I don't think it's particularly unusual even for me to speak like this though.

Well but, now that I know what this person's purpose is, I have no intention of responding to him.

"Then give up. I don't want to be alone with a boy other than Nii-san."

"......It's starting again, this girl is"

Rikka is exasperated, but it's of no concern to me.

When I told him so that I wouldn't be alone with anyone other than Nii-san, he bit his lip in frustration and said something like this.

"Is it true? That you are going out with your brother......"

"It's true you know? I've been talking about love affairs with Nii-san quite a lot here, so I thought you knew, though."

"......Isn't it strange? I mean, you are brother and sister you know?"

For a second, I ended up looking at his neck.

It's so thin......In what way would the blood flowing through that artery make a spray of blood I wonder, I wonder how much force I have to put into that neck bone to make a nice satisfying snapping sound...... aah no good no good. Immediately, I discipline myself from about to end up falling to the dark side.

(......When something gets me pissed off, it might be that I have a talent for killing people when my gaze turns to the neck, which is naturally one of the weak points of people.)

While I thought, "What a dangerous thing to think about," I let out a sigh and continued my words.

"We are stepsiblings, so there's no problem anyway. Or rather, I don't want you, who doesn't know anything other than names, to easily step in, I think~. Won't you hurry and go back?"

"......"

By the way, as if responding to my emotional fluctuations, Mashiro took a position ready to kill him at any moment.

"You said it clearly didn't you." (Rikka)

"I think it's a kind way to do it, though see. Well, wouldn't he too change even his mind if he knew the old me? Nee, Rikka?"

"-......when you're saying that, I'm weak too aren't I. That time is......umm."

"Well, I don't care, so it's fine. At that time, there was me as some of the cause anyway."

There was me as some of the cause, who unconsciously entered people's hearts and made them hold fear.

That's why there's no need for Rikka to feel hurt about this, but maybe it's because she feels even the slightest of guilt like this, or it might be that even if I don't go as far as to completely accept it, she treats me as a friend.

From then on, it became after school, and I immediately left the classroom.

I was invited to play by Rikka and the others, but I declined because I had a promise with Nii-san.

"Chisome, quickly"

"Listen here. You can't run in the school hallways. So don't be rash."

It would be easier if I could also disappear my figure like Mashiro. But as expected, nonetheless with supernatural powers, to that extent, while unfortunate, I can't do it.

Like that, I'm jealous of Mashiro's abilities, and I actually feel her love from the bottom of her heart for Nii-san; it was at that time.

"......hmm? if I remember correctly, that person is"

A senior (senpai) girl passed in front of me.

Somehow the place she headed to seemed to be the staff room, but I became a little curious about the state of that senior, who seemed like she was troubled about something.

Normally, it's not something I should be particularly worried about, but still, the reason why I was curious about someone I've never talked to――that is because it was the person I heard about from Nii-san.

"Kitagawa Akane-senpai......that person is also a heroine Nii-san said." (Chisome)

"......Fu~n, it might be the first time I've seen her." (Mashiro)

She is a beautiful woman, but if I were to say which one, she's a girl with a very cool image.

It's a pity to think that there is a world where even someone like that might be made a partner (lover) with that idiot, but that idiot doesn't exist in that world, and properly as the protagonist, he should be a suitable person, so it's not particularly a pity, I think.

"Somehow, was her expression dark?"

At Mashiro's question, I nodded.

Probably, if it were normal people, it would be an unnoticeable sense of discomfort, but I was, after all, able to notice it.

Although I was curious because I had heard about her from Nii-san, originally, she's most likely to be someone who I care not about at all is without a doubt, so I didn't even call out to her as I had no particular involvement with her.

"Nii-san!"

"Otto"

Soon after that, I met up with Nii-san at the school gate.

We are such an idiot couple to the point that the people around us are envious. Nii-san seems embarrassed to be told so, but I'm completely fine with it though~.

"Nii-san, shall us let's kiss"

"Onii-sama, let's kiss?"

"After we get home alright? I'll let you do whatever you want after we get home......No, let me."

Gee, oh Nii-san!

True to his words, I kissed him to my heart's content after returning home......I did it hard!
