Someone Who Believes They Can Live Normally in a World Where Chastity Is Reversed (Did You Think You Could Live Normally in a World With a Male-To-Female Ratio of 1:5?)

My classmates in the basketball club were mostly nice.

Recently, things have gotten a bit better thanks to Onii-san, but there were times when I was bullied by the seniors before, and these kids always stood by me…

Everyone gets along well, and I trust them.

So, when we become third-years, I thought it would be nice for all of us to work hard together in tournaments and stuff.

“Eh, What’s up with that cool guy over there!! Why didn’t you introduce me to him, Yuka?!”

“I might come here every day…”

“Yuka, you were planning to monopolize him, weren’t you! What have you been up to until now? Did you… did you do naughty things? How far did you go? You silent pervert!”

…I’m starting to really dislike her.

Why did things turn out like this?

Today, we didn’t have club activities, so since everyone was free, we decided to play basketball.

We talked about using the gym that’s open to the public, but it’s too hot inside, so we decided to play basketball outside.

Luckily, I knew a park where I played basketball with Onii-san, so I suggested that.

…It’s Onii-san’s place, so I was a bit hesitant, but…

While we were playing basketball at the park, when we were taking a short break, a man started playing basketball on the court while we weren’t looking.

“What! Someone took the spot while Miho and the others aren’t here!”

“…Wait, isn’t that a guy? It’s rare to see someone alone.”

After hearing my friend’s words, I looked at the person… and immediately recognized him as Onii-san.

His height, his vibe, and his basketball play.

Even if I had just one of those, I’d recognize him, but having all three, there’s no way I wouldn’t know.

My beloved person.

“Hey, where are you going, Yuka?”

“Yuka, stop! Even if you’re a silent type, it’s a crime to approach a passing stranger!”

…Isn’t that too rude?

I’m not a silent type! I’m just average! Average, I tell you!!

And so… things were going well until I approached Onii-san and called out to him…

Before I knew it, three people came, and unbelievably, they asked Onii-san for basketball coaching!

T-That’s my privilege…!

“Uh, um, Onii-san is personally coaching me…”

“What kind of coaching are you getting? Details~”

“I thought you’ve become more mature recently… in that sense.”

“That’s not it!!! Seriously, stop saying rude things to Onii-san!”

Ugh, this is the worst.

Now I don’t know what they’ll say to Onii-san…

“Ah, Yuka, I think I’ll go home after all. I’m sorry.”

“Ah! N-No, wait! Onii-san, please don’t go…”

“…? Really?”

I don’t want Onii-san to leave.

But I’m anxious that the three of them might say weird things to Onii-san.

I’m so confused~!!

While that was happening, the three of them were happily introducing themselves to Onii-san.

Is everything going to be okay…?

Ah. Miho’s holding Onii-san’s hand tightly…

Ugh~ I feel so uneasy~ Onii-san is mine…

“Mo~~~~~~!!!”

If I had known this was going to happen, I wouldn’t have suggested the park?!

—-

Surprisingly, when we actually started receiving basketball lessons, everyone was quiet and listened attentively.

I guess everyone really does love basketball.

Realizing that made me a little happy. Onii-san adjusted his coaching to match their levels, and he even gave me proper guidance too.

Every time, it makes me feel special and happy when he says, “I’ve told you before, Yuka,” to me.

The time I spend with him is irreplaceable to me.

I hope it’s the same for him too.

“Pass, Onii-san!”

“Onii-san, you’re amazing!”

…But anyway, why does everyone call him “Onii-san”?

He’s my Onii-san… I feel weird.

Anyway, if everyone calls him Onii-san, then I should change how I address him.

Should I call him “Masato-san”? But he seemed happy when I called him Onii-san before… “Masato-nii-san.” Yeah, I’ll go with that.

“Onii-san, Onii-san!”

During our break, Suzuka ran over to Masato-nii-san.

…I have a bad feeling about this.

“What does Yuka-chan mean to you, Onii-san?!”

“Hey, Suzuka!?”

What are you saying!!! I immediately grab Suzuka’s head.

“Ouch, ouch! …But Yuka-chan, you’re curious too, right?”

“Guh…”

Well, yeah, I’m curious. What am I to Masato-nii-san…?

Considering the other day… maybe, perhaps he might even… like me…

“Well, Yuka… It hasn’t been that long since we met, but she’s already like a little sister to me.”

My chest hurts a bit.

“A… little sister…”

A sister.

In terms of intimacy, I think it’s close. I can feel that he treasures me. But being seen as a sister… No, that’s not right.

Because being seen as a sister means he probably won’t see me as anything more. He won’t see me as his girlfriend.

I like Masato-nii-san. So, I want him to like me back.

The pain in my chest spreads slowly.

“And does Onii-san have a girlfriend~?”

Is that you, Miho?! That’s quite an intense question, you know?!

“Nope~. Single.”

Phew…! G-Good.

If he had said yes, I probably would have cried. Seriously. I would have cried and gone home.

“Huh~? Surprising! Okay, okay! Then, I want Onii-san as my boyfriend!”

“Miho!!!”

Seriously, Miho, you’re so…!

Wait, didn’t you say you had a boyfriend already?!

—-

After practice. After taking a breath, I went to thank Masato-nii-san.

Alone.

“Um, thank you very much. Um, Masato-nii-san.”

“Hmm? Hmm… No, I should be the one apologizing for bothering you… They’re good kids. Take care of them.”

“Yeah, I will. If you’d like, please come watch our game sometime.”

“Oh, definitely. I want to see Yuka playing in a game.”

…I’m happy.

Just hearing that warms my heart.

I’m simple-minded, aren’t I…

Now then. That’s why I want to change the perception of being a little sister.

Suddenly, the words come out of my mouth.

“Um… um…”

“Hm?”

But what should I say?

Many words come to mind, only to vanish.

I don’t have the courage to confess.

But saying “Please see me as a girl” is practically a confession.

I’m not against being treated like a sister. It’s nice when he pats my head or praises me. But I want our relationship to go a step further.

“…It’s nothing.”

“…? Then, see you next time. I’ll accompany you for practice anytime.”

I’m… such a coward.

In my heart, I scolded myself.

But in front of him, I smiled.

“Yeah. Next time, I want to practice with just the two of us.”

“Hahaha, yeah. It’s better if it’s just the two of us when teaching Yuka.”

Just the two of us…

Those words make my heart race.

I wonder if Masato-nii-san also thinks that being just the two of us is good.

…

Someday, for sure. I’ll make Masato-nii-san notice me even more.

My love, unlike everyone else’s…

“Yes!! Please teach me again!”

Because I’m serious.

…

That night.

I changed into my pajamas and lay down on the bed, thinking alone. What I recall are Masato-nii-san’s words from today.

[She’s like a little sister to me.]

A sister, huh?

How can I graduate from being a sister?

“Well, I have to make him notice me, right?”

Ways to make someone you like notice you… Even after searching online, I honestly don’t know. There aren’t many examples of older men, so it wasn’t very helpful.

But, making him notice me is important.

To make him notice… how?

Hugging him? No, that’s no good. I was emotional last time, but it ended with just getting my head patted, like usual sibling affection.

Holding hands? Hmm, isn’t hugging better?

In that case, hugging is better…

“Kissing… or something.”

Suddenly, my face heats up. I bury my face into the pillow.

No, no, no! That’s too much.

But, it might be nice. If I do that, he’ll definitely notice me.

In my mind, I see Masato-nii-san’s beautiful face.

His lips…

“…!!”
