My Little Sister Is the Best F*p Material

Volume 1 Chapter 10: A Few Minutes Before School for a Certain Brother and Sister

It had been years since I had seriously faced my own face.

The person reflected in the mirror of the washstand looked like a stranger to me. Could a slight change in hair length make such a difference? I had thought that a cheap haircut was enough, but I was looking at my unfamiliar hairstyle with a gaping mouth, having had my hair trimmed by the hairdresser introduced to me by Miyu.

Would I be laughed at by everyone if I went to school like this? My anxiety was growing. Just the fact that I had paid a lot of money for a haircut was enough to make me a laughingstock in my previous life.

“Hmm…”

I kept fiddling with the collar of my blazer and my tie, and my outfit just didn’t look right. Eventually, I began to regret it. I had been persuaded by my sister, but was it a mistake to follow a woman’s taste after all?

I set my hair with a dryer and wax as the hairdresser had taught me, but somehow it looked worse than before. I had thought it looked good right after I got my hair cut yesterday, but it seemed that even the way of styling hair was different between professionals and amateurs.

It was almost time to go to school, and I even felt like I wanted to skip school. No, it was too embarrassing. I even felt that my life without being popular was better than being seen in this state.

“… Onii.”

I heard a voice from the bathroom door and quickly withdrew my hand, which had been touching my hair. Miyu was watching me, sticking out half of her body from the door.

“What’s wrong? Why are you hiding like that?”

“Nothing. I just thought it was a good sign…”

Miyu, who should have finished getting ready first, had come all the way to the bathroom to say that, so it must have been her true feelings. Was it really that great to start caring about my appearance? People should judge others by their character rather than their looks, but in the end, they would exclude those who didn’t care about their appearance.

“Isn’t it a bit narcissistic of me to fiddle with my hair in front of the mirror…?”

“Of course, you shouldn’t do it in front of people. At least, you should fix it in private and not care about it once you’re outside. You should also avoid doing it in public restrooms.”

Miyu came into the bathroom, lecturing me.

She faced me head-on and quickly scanned me from my heels to the top of my head.

“Hmm. It’s a total failure.”

Miyu bluntly denied it, like a strict boss checking a document.

Even so, everything except my hairstyle was the same as usual. Well, if Miyu said it was a failure, I could understand.

Looking at Miyu’s appearance again, she’s beautiful. Even though I have no intention of hitting on her, her looks are polished to the point where those words come out naturally. Her long hair is well-kept with not a speck of dust, her skirt and blouse have no wrinkles, and the fit of her clothes, including her underwear, is probably perfectly tailored to match her.

Her standing posture was also impeccable. Her back, hands, and feet were positioned perfectly. Her manners and etiquette were embodied, and I could understand why our ancestors compared them to flowers.

Miyu, wearing a uniform that was a kind of attribute in itself, looked as if she were wearing the clothes, rather than the clothes wearing her.

“You haven’t had this blazer cleaned for a while. There are too many wrinkles. You must be rolling it up and putting it in your bag, right?”

Miyu pulled and stretched my clothes from the sleeves to the back. She was speaking in an unusually emotional tone, but she wasn’t handling me roughly.

“I’m just wearing a jacket because it’s cold today. The clothing changeover day has already passed, so I’ll take it to the cleaners next week.”

I wouldn’t have noticed the need to take it to the cleaners unless my mother told me to. I didn’t even know how to do it.

“The hem of your shirt is too close to your waist. The waist positioning is also wrong. Take off your pants.”

Miyu unbuckled my belt without giving me a choice. Well it’s not like it’s the first time she’s going to see me in this state, but it was the first time I had been undressed, so I felt strangely embarrassed.

My pants were pulled down, my shirt was adjusted, but she didn’t pull my pants back up. Miyu, after staring at my belt intently, wrapped it around my waist and furrowed her brow at its excessive length.

“What’s this?”

“I’m sorry.”

I apologized profusely, standing with my pants exposed. Miyu unfastened the buckle of the belt, which was too long for my waist, and sighed as she looked at the end of it.

“Didn’t you know you could adjust it?”

“I know, but I don’t know how.”

“Moo!”

My sister was angry, pouting. It was the first time I had seen such an expressive Miyu.

“I’ll be right back with some scissors.”

“Eh, it’s okay. I’ll be late for schoo sol… and there she goes.”

Miyu ignored me and went back to her room.

I go to school by bicycle. If I pedaled hard, I might make it to the morning assembly on time.

“— Listen here, Onii-chan.”

Miyu came back and cut the belt to the right size. The original belt wasn’t that long, so if I fastened the buckle to the innermost hole, it would barely stay on my stomach. I tried putting the belt through my pants, and it seemed that the looseness of my lower body had indeed disappeared.

“I’ll get rid of the dust, too.”

Miyu used adhesive tape to pat my uniform.

I was running out of time. I had to dash after this. I’m going. I’ll go no matter what Miyu says.

“Hmm…”

Miyu was groaning as she removed the dust from my uniform. I had a bad feeling about this.

“The length of your tie doesn’t match.”

“Okay, okay! I’ll fix it! I’ll fix it when I get there!”

I made my best gesture to show that I was in a hurry. Our homeroom teacher was known for his bad mouth and personality. If you were an excellent student, he might listen to your excuses, but for ordinary people like me, the only way to survive was to avoid upsetting him.

“No complaining.”

Miyu gently stopped my resistance. She reached for my neck and started fiddling with my tie and collar. I also completely gave up.

We were both silent, and the only thing that continued was the ticklish contact. When my tie was tightened, my back naturally straightened.

“Since you look good now, it’s okay to be late.”

Miyu finally closed the front button of my blazer. She patted my back and turned my face back to the mirror.

“Haa…”

That exclamation was not an agreement to Miyu’s opinion.

It looked good. The outfit that I had always thought was uncool, no matter how I changed the way I wore it, looked quite impressive, even though nothing had changed.

“You should button the jacket when you stand up and unbutton it when you sit down.”

“Hmm, hmm.”

I reached for the second button of my jacket, as Miyu had instructed.

Then, my hand was slapped hard.

“You don’t button that one.”

“Okay.”

My sister was quite strict.

“Manners change depending on the era and region, so you don’t have to be so strict about them. But since the uniform is designed to look best when worn properly, it’s a good idea to be aware of that.”

“Understood.”

Miyu is certainly cute, and she’s also tolerant when it comes to erotic things, which in itself is enough to make her quite charming. But, I couldn’t understand why I was so drawn to her.

The reason for that was finally revealed today. She had been making such an effort without even realizing it. That’s why she was so popular with both men and women.

I was finally freed from the bathroom and had somehow moved to the entrance, slipping on my shoes with a sideways glance at my bag. I felt so lighthearted. My usually worn-out leather shoes somehow looked like they were shining.

“……?”

This wasn’t just a feeling. The leather shoes were really shiny.

“Just for today. The first day of an image change is crucial after all.”

Miyu put on her shoes next to me.

Wasn’t she doing too much for me? What’s with her mindset? I had to like another girl from now on. Did this perfect sister of mine understand that?

“Well, thank you.”

“You’re welcome.”

She had her usual composed expression again. She was carrying her bag in front of her and looked like someone who attended a real girls’ school, but it felt really strange that we were heading to the same school I also attended.

“Well, let’s go.”

If the traffic lights were connected, I might be able to make it to the morning assembly just in time. I stopped, holding the doorknob of the entrance, thinking about how to avoid being late.

I was suddenly overcome with an unfamiliar anxiety. My head was afraid of the disharmony that someone was behind me.

That’s right. I had never left the house with Miyu before.

“Miyu, aren’t you also going to be late?”

You’re definitely going to be late, aren’t you?

It took me, a guy, about fifteen minutes to go to school even by bicyclel. With my current school, I’m already late even with a reasonable commute time. So, Miyu should be in the same boat.

“I was very late because I had to accompany my Onii-chan, who couldn’t even dress properly.”

Miyu, with no sense of urgency, stared at me.

Standing perfectly still. As if waiting for something.

Holding the key to the bicycle in her hand, she gazed up at me.

“Ah…”

One chance. The hope of making it in time was not spun from my mouth.

“Being late is troublesome, right?”

“Yes.”

“I could make it in time if I really tried, though.”

“Looks like it.”

My sister still didn’t move. I was impressed that she had calculated it all.

“Ah! Fine! I’ll just take you there, okay!?”
