Gloomy Outside, Gal Inside ~Dealing with My Step-Sister Isn't Easy~ - Chapter 05: Miu ①

Chapter 05: Miu ①

“Miu, I’ve been talking about it for a while, but I’m getting remarried. We’ll be meeting them soon, so keep your schedule open. There’s a boy who is slightly older than you, but he seems like a really good kid, so please rest assured.”

I heard suddenly that we were going to have a new family…

I had no objection to remarrying if it would make my mother happy for me, and if the other person had a son, I had nothing against it.

For me, if it makes my mom happy, I had no objections to her getting remarried, and it didn’t matter if the person had a son.

…Well, maybe I’m exaggerating a bit.

To be honest, I was a little confused. You see, I was used to being an only child, so I couldn’t really grasp the feeling of having a brother.

“I’m Kanato Kuon. Nice to meet you.” [Ayato’s Father]

Onii-chan… Nii-san. The first time I met him, I thought he was just an ordinary person.

He wasn’t particularly handsome or ugly… Just ordinary. Yeah, he was really just an ordinary person, but after we started living together… I quickly got to know Nii-san’s kindness.

“This is Miu-chan’s room.”

“If there’s anything, let me know.”

“I’ll help with heavy things, so don’t hesitate to ask.”

“I’m going out for a bit. Miu, is there anything you want, like ice cream?”

I think Nii-san was having a hard time figuring out how to treat me.

Anyway, Nii-san was always considerate of me… Even though I wanted to say he didn’t have to go that far, having an older brother who thinks of me like this felt warm in some way, so I interacted with him as a little sister, trying not to cause him any trouble.

“I’m back, Miu.”

“Welcome back, Miu.”

After living together for six months, there was no more hesitation between us.

I used to be timid and had a rather gloomy personality, but being influenced by Nii-san, I started talking more, and Nii-san started calling me by my first name without honorifics.

Of course, it wasn’t just that. On days when Mom and Dad went out and we were alone together, on my birthday, and in other moments, Nii-san genuinely cared about me.

“Why is Nii-san so kind?”

“Kind… Isn’t that normal? Well, honestly, I didn’t know how to treat a little sister if I never had one before.”

“Is that so? But… Well, I really think you’re kind.”

“Is that right? Well, I’m happy too. It’s, um… I’m going to say something a bit embarrassing, so forgive me, okay?”

“Huh? Yeah.”

“Spending time with my little sister, Miu. I started thinking, ‘Oh, so having a little sister can be this cute.’ Once I felt that way, as an older brother, I wanted to spoil you and be relied upon. I wanted to show off a bit.”

“Huh… Really?”

Nii-san suddenly said something like that, and I was surprised.

But… Was it from this point? I think this was the moment when Nii-san’s presence became significant in my mind.

And at the same time, it was also when I started being bullied in my class.

“Hey, plain girl. You kinda smell, yeah? It’s not just my imagination. Can you stay away from me?”

Back then, I was… really simple.

I had no interest in fashion, didn’t care about my messy hair, and my glasses were extremely nerdy, but I thought it was fine.

At first, I thought I could handle it if I just endured the little annoyances.

But because I didn’t react much, the bullying escalated… My desk was hidden, vases were placed on it, and such obvious things were done to me, but the teacher turned a blind eye.

“Miu? Is something wrong?”

“No, it’s nothing.”

I didn’t want to burden Nii-san, who was living in a new environment as a high school student, and I didn’t want to worry Mom and Dad either.

So I endured, endured, and endured… But the malicious words and actions unexpectedly hurt my heart… Enduring it became increasingly tiring.

“N-Nii-san…?”

“Miu.”

One day, Nii-san greeted me at home with an angry expression.

I became anxious, thinking I did something wrong, but instead of being angry at me, Nii-san was angry because he heard from my friend that I was being bullied.

It was exposed… I felt disappointed, but I leaned on Nii-san, who embraced me, entrusting everything to him.

“It’s okay now. It’s okay, Miu.”

And it was true. The word “okay” turned out to be accurate.

The bullying became known, and I must have become a nuisance to the ringleader and her followers.

In these times, it’s rare for someone to truly reflect when told to reflect.

That’s why I stopped going to school directly and started taking online classes.

“Oh, I’m glad I can see my little sister’s smile again today.”

“Hey, Miu! Today, while I was hanging out with some idiot friends, I ended up getting soaking wet.”

Even though my environment changed, Nii-san remained the same.

Whether it was to avoid reminding me of the bullying or not, Nii-san continued to treat me as he always had and considered me his precious little sister.

“Nii-san, thank you for protecting me. Thank you for saving me.”

But I have to express my gratitude properly.

Nii-san was taken aback by my sudden gratitude, but he quickly placed his hand on my head and said with a smile.

“It’s only natural. What kind of big brother would I be if I didn’t help my adorable little sister? If anything happens again… well, no, it shouldn’t, but still. I will always go to help Miu.”

“Nii-san…”

“No matter where you are, I will find you. No matter what happens, I will always come to help Miu… So if anything happens, call me immediately. It’s a promise between a reliable Onii-chan and you!”

“…You don’t have to say it yourself, Nii-san ♪”

“It’s okay for me to show off like you said before, okay?”

Seriously… It’s impossible when he does things like this.

I am simple… I’m so simple… Even though we’re siblings, even if it’s just a sense of duty, I thought something like that would never happen, but I take back what I said before—I’m completely in love with Nii-san.

“…Nii-san… Nii-san♪”

When I think about Nii-san, my body gets hot, and it throbs in my lower abdomen, to the point where it’s almost squealing.

I learned to do things alone when I was in 8th grade, but of course, imagining things and doing them with Nii-san… felt natural!

“Oh… Is this… Whoa!?”

Back then, well… I used to blush when I saw explicit things.

But when I entered Nii-san’s room, I happened to come across a manga depicting a lewd life with a little sister gal… and immediately, it struck me that this was it.

Of course, I didn’t act on it right away. I casually brought up the topic with Nii-san or sneaked into his room when he wasn’t there. I also learned that Nii-san had a fetish for the genre of an erotic little sister.

“…Originally, I had bright hair and big breasts… They were too big and bothersome, but seriously, they’re nice!”

Everything seemed to be on my side!

For someone like me who never really had any desires, aiming to be different from my usual self felt refreshing.

Only in private, I made my hair silky smooth and dressed a bit more flashy… I aimed to become a little sister gal that would appeal to Nii-san’s taste. As a result, Nii-san was surprised when he saw me, but his eyes clearly held a definite desire.

“Nii-san was… looking at me with such a lewd gaze… Ahaha♪”

It was pure pleasure.

Not only did the change in appearance affect my outward appearance, but it also influenced my inner thoughts… I became “me” from that moment on.

But unlike the heroines in manga, this appearance was strictly limited to private situations… If this appearance is considered the real me, it’s enough that only Nii-san and our family know.

“Well, I never had an interest in being fashionable… but it’s not bad. Am I cute and sexy? Am I becoming Nii-san’s type, I wonder♪”

Well, Nii-san probably has no idea why I decided to dress this way… But if I can tell him someday, it might turn into something fun.

“Is this good for today?”

And as for taking selfies… well, I wanted to see how others would react.

When I first posted a picture fully embracing the gal persona, and the only responses I received were “cute,” “beautiful,” and “sexy” from people other than Nii-san, it solidified my belief that this appearance wasn’t a mistake.

That initial picture unexpectedly went viral, and now I have over 40,000 followers on Twitter. I’ve become quite popular… Of course, I’m very careful when posting selfies.

“…Kufufu♪”

And also!

I have one desire – when I can enter that kind of relationship with Nii-san, I want to show off a picture of us standing together, completely naked. 

[TLN- What are you saying Imouto-chan!?]

As usual, I would hide my face so no one could recognize me. I want to declare that this body, which you all desire endlessly, is already exclusive to someone. I secretly want to see how those who keep requesting my attention will react… I’m really looking forward to it.

“Hah… Nii-san, I love you♪ I love you so much♪”

Well, recently, being with Nii-san has been so much fun… It’s been so blissful that honestly, I’m starting to think that posting selfies doesn’t really matter.

“Miu~”

“Yes~!”

“Do you want to go ahead and take a bath~?”

“I want to go with Nii-san!”

I want to take a bath with Nii-san!

When I said that, Nii-san blushed and ran away… Fufu, be prepared, okay?

If I confess to him now, Nii-san will surely hesitate, considering the boundaries of being family and all. But if he can’t resist anymore and comes to me… Well, that will be the moment when I know he wants me, right♪
