Chapter 06: My Cute Little Sister Can’t Sleep Peacefully, Fearing I’ll Take Something Important from Her

“Takuya-nii, can I use your computer for a sec?!”

I showed no signs of being startled by the sudden intruder. That’s because the one who had entered was…

“…Miyu, how many times have I told you to always knock before coming into my room?”

My sister Miyu was the culprit. She was sixteen, a year younger than me. Even if you set aside any brotherly bias a big brother may have, I would say that she was rather cute. She had a different sort of charm compared to Manami, my one-sided childhood love. That’s why she often caused me various troubles…

“Back then, we used to sleep in the same bed, so there’s no need to be shy now, Takuya-nii!”

Hearing those words from Miyu made my heart skip a beat…

About half a year ago, Miyu and I had been sharing a room. She had once secretly hidden in the upper bunk of my loft bed. I was really taken aback at that time. Regardless of her being my sister, I was still a healthy high-school sophomore. There shouldn’t be any room for mistakes though. And there was a deep reason for that…

…In truth, Miyu and I are step-siblings, with no real blood relation between us.

My father remarried when I was in elementary school, and that’s how Miyu and I started living under the same roof.

I still remember vividly the day we first met.

A cute girl, wearing a large straw hat and sporting skin as white as snow—completely opposite to my sunburnt self—was standing in front of the entrance.

I lost my biological mother when I was very young and was raised solely by my father, so I wasn’t very accustomed to interacting with women.

Initially, I behaved rather brusquely towards Miyu. Looking back, I was really just a stupid kid back them.

Our new mother treated me with a mix of kindness and sternness, as if I were her real son. So when Miyu said that wanted to sleep in the same room as me, our mother trusted and understood it and allowed it without much fuss..

Miyu had also enrolled in the same girls’ high school as Manami this year, Kimisarazu Minami Girls. Although we now had separate rooms, her unabashed entry into my room like she owns the place was truly troublesome for me.

“M-Miyu, wasn’t it you who snuck into my bed on your own!? Crying, ‘Onii-chan, I had a scary dream and can’t sleep, I might wet the bed!'”

“S-Stupid brother! I never said anything about wetting the bed!”

“Is that so…”

I purposely teased her lightly. My sister Miyu has always been easy to read, which makes it fun to tease her.

Her emotions quickly show on her face…

“Takuya-nii, forget all that. Just let me use your computer, quick!”

Pouting, she sat in the chair at my desk. Given the lingering warmth of the days, her outfit consisted of a light hoodie and shorts.

Ever since entering the prestigious girls’ school, she seemed to have grown taller. Her modest features still remained, particularly on her upper body. If Miyu were curvy, it would be hard even for me to know where to turn my gaze to. The current slightly flat appearance suits her well and is quite cute though…

My gaze inadvertently fell on her healthy-looking thighs peeking out from her shorts.

“Takuya-nii, I don’t know the login password. Could you come here and enter it?”

She booted up my laptop and immediately made such a request. Such a high-maintenance sister… Today, Miyu had her long hair tied back in a ponytail. Whenever she moved her head, the cute, little tail swung, momentarily capturing my attention.

“…Alright, alright. I’ll enter it right away; just wait a second.”

Reaching over from beside Miyu, I typed in the login password. My arm accidentally brushed against her shoulder as I did so.

“…Ah!?”

Miyu suddenly flipped around with the force of a young fish, startling me in the process.

“Miyu, is something wrong!? Your face is red all the way to your ears…”

“…I-It’s nothing! I’m about to use the computer to do some research, so Takuya-nii, don’t bother me, okay!?”

What’s her deal? She’s acting strange… suddenly getting flustered and then snapping at me.

“I won’t secretly peek or anything; I have zero interest in what you’re researching anyway…”

It’s pretty rude to talk like that to the person you’re borrowing the computer from. If she feels that way, why not save her allowance and buy her own computer?

Miyu, unlike me, has a knack for saving money. Our parents even praised her for it. But what is she planning to use all that savings for anyway? Well, she’s still a high school girl; maybe she wants to buy some cute clothes or something with it.

Ignoring her, I laid down on the sofa and started fiddling with my smartphone.

The loft bed is space-efficient, but it’s a hassle to climb up to the top every time, so I usually use this sofa for anything other than sleeping. It’s also a favorite spot for my beloved cat, Mugi, to bask in the sun. My room is perfectly positioned for drying laundry, with great sunlight. Glancing out the window, I saw Miyu’s colorful underwear swaying in the wind today as well.

The light, rhythmic sound of keyboard clicks filled the room.

The intermittent noise became a sort of lullaby for me, and I soon found myself dozing off on the sofa.

＊＊＊＊＊＊＊

“W-What is this~~!?”

I was jolted awake by Miyu’s shrill voice. What on earth was happening?

I sprang up from the sofa where I’d been sleeping and rushed over to the computer desk.

Miyu had stopped typing and stood there in a daze, her shoulders trembling.

Her unfocused eyes were staring at one spot, and that spot was…

The screen of my laptop displayed a page from a major search engine. A dropdown menu showed past search results.

“What the!?”

I couldn’t hide my surprise and found myself frozen on the spot.

[How to have ♡Love Love♡ ‘fun’ with your sister]

[Spend the night with your sister in a sailor uniform♡]

[Downing premium sweet potato shochu in one go!!]

Whoa, whoa, whoa! What’s with this ridiculously lewd search history!? I have absolutely no memory of this; it’s a false charge! Miyu, Onii-chan definitely didn’t do this.

…Psssh!

It felt like smoke was coming out from the top of Miyu’s head… Her face was turning bright red in seconds.

“Onii-chan, you pervert~~!!”
