When We Found Out We're Not Blood-Related, My Little Sister Became Seriously Love-Brained ~When a Little Sister Stops Being a Little Sister, the Ultimate Heroine Emerges!~ - Chapter 7: I Tried Analyzing My Little Sister

Chapter 7: I Tried Analyzing My Little Sister

A single sake chocolate melts memory. Sweet heat loosens the distance with Suzune.

Like keeping an “observation notebook,” I pick up gaze, fingertips, and breathing in order, trying to solve the equation of Suzune’s mood.

—While truly knowing that analysis is just another word for love.

“I’m going to the bathroom real quick.”

I’m waiting for Suzune at the supermarket entrance right now. Now that I think about it, Suzune is my little sister, so I’ve never looked at her objectively as a woman.

I’m bored, so I’ll kill time by analyzing my little sister.

First, her face.

Fair skin, big eyes. Double eyelids with long eyelashes, and maybe it’s just me but her pupils seem bigger than other girls’. She’s definitely in the beautiful girl category.

Next, her body.

Large chest with a slim waist. Healthy thighs with slender ankles. She says she hates her legs because they’re fat, but actually, she has a good figure. I know this. Even when Suzune occasionally skips bathing, she still smells good the next day.

And her personality.

Foul-mouthed and violent. Even though her clothes look flashy, she’s a serious girl. Actually a hard worker who’s good at both studying and sports. Her personality is kind to everyone except me. Also, maybe sometimes a tsundere.

Looking at it objectively again, she feels like a high-spec beautiful girl. Well, aside from being my little sister and her foul mouth.

※

“Sorry for the wait!”

Suzune came back.

“What, that girl. She’s so cute, is she a celebrity?”

Some unfamiliar aunties are gossiping about Suzune.

No, seriously.

Just as the ladies say.

Then Suzune glared at me.

“Hey, you.”

She’s angry about something.

“What?”

Did I mess something up?

“When I came out, you were looking at other women. Your nose was stretched out, grinning stupidly. That’s gross and unbelievable.”

What a false accusation.

I was actually looking at Suzune.

“So what? It’s my business.”

Ow.

Suzune kicked my shin.

“Even though you have such a cute little sister, you’re too cocky. You virgin.”

(Seriously foul-mouthed, this person.)

It’s frustrating to just take it.

I’ll talk back a little.

“I was only looking at Suzune though.”

“Fweh.”

Hm. A weird sound effect came from Suzune.

Suzune looked down and went silent.

She occasionally glances this way, but when our eyes meet, she tries to hide her face with her bangs.

If I add one thing to my earlier analysis, Suzune gets jealous easily.

※

When we got home, I was chased away to my room. Suzune put on an apron and looks busy. Apparently she’s making dinner.

I waited for a while, but there’s no word from her.

Looking at the clock, nearly an hour and a half had passed.

That’s a bit too long.

I got hungry.

I heard the creaking sound of someone coming up the stairs, and the door opened.

“I got hungry.”

When I stood up, Suzune had tears in her eyes and was pursing her lips.

“…I gave up on making dinner. Sorry, I’ll order delivery.”

I went down the stairs.

“H-hey. Don’t look!!”

Suzune pulled my arm.

※

Actually, even Suzune who can do anything has a weakness.

That’s cooking.

“I’m your older brother, you know? I know your abilities.”

In the kitchen, dark matter substances on plates greeted me.

This is quite…

Today’s especially impressive.

Dishes clad in deeper jet black than usual, perhaps in proportion to her effort.

I sat down and said:

“Come on. Sit down. Let’s eat quickly. I got hungry.”

“If you eat that, you’ll get a stomachache.”

Suzune looked down.

What kind of dish is this?

It’s on a plate, round and black. Ketchup is placed next to it.

…Maybe omurice?

Yeah. It’s probably omurice.

I shook off Suzune’s restraint and took a bite.

The salt’s a bit strong, but it’s not bad.

“No, it’s actually good? You should try it too.”

Suzune looked at me with half-closed eyes and took a bite.

“Don’t lie… This has to be bad. Wait, huh?”

“Right?”

I put a second bite on the spoon.

“Yeah. It looks bad, but it’s delicious!!”

Suzune smiled.

“See?”

“The appearance isn’t impressive, but I like the inside. Just like you. Hehe.”

Suzune looks happy.

She’s probably trying to compliment me, but is it just me or is that slightly annoying?

Also, this girl.

She has this ‘I’m eating this for the first time’ vibe, but didn’t she taste-test it?

“Thanks. By the way, Suzune, don’t you taste-test?”

“I don’t. Because if you make it according to the recipe, it has to taste that way.”

I see.

It’s not decided, which is why dark matter gets produced though.

Should I cook with her next time?

Cooking together would be fun, like when we were kids.

“Thanks for the meal.”

After eating, we wash dishes side by side. Suzune wipes the dishes I wash.

“Doing this kind of feels like the old days.”

When I said that, Suzune pressed against me without saying anything. Her body warmth gradually transmits to me, warm.

Even though she’s always foul-mouthed.

Sometimes she’s very girlish.

It throws me off.

After cleaning up, we decided to watch TV together.

Then Suzune clapped her hands.

“There’s a movie I’m curious about, will you watch it with me?”

“Sure, I don’t mind.”

I wonder what kind of movies Suzune likes.

Suzune talking to the TV remote.

The movie she chose was surprisingly horror.

“Mom got this from a friend. Let’s eat it without permission.”

Suzune said that and brought chocolate from somewhere. High-class looking chocolates individually wrapped in silver foil.

“Where was this?”

“Under-floor storage. Mom hides various foods there.”

Suzune picked up a chocolate and laughed mischievously.

I laughed back.

It’s like when we were kids.

…Doing mischief together is fun.

“Let’s watch it quick!”

When the lights went off, Suzune nestled against me like a cat.

The movie is the jump-scare type of horror, where the sound effects suddenly get loud sometimes. Suzune flinches each time, and the good scent of her shampoo wafts over.

Suzune eats chocolate every time she’s surprised.

Maybe she wants sweet things due to stress.

(She’s getting scared a lot, but does Suzune really like horror? Oh, this chocolate might be good.)

It’s dark so I can’t see well, but the chocolate has sweet flavored liquid inside.

When the movie ended and I looked at Suzune, she had her eyes tightly shut and was pressing her chest.

I decided to ask.

“Suzune, do you like horror?”

Suzune shook her head side to side.

“I don’t like it. But my friend said that after watching this movie, things progressed with her boyfriend.”

Suzune touched her knees together several times before placing her hands on her thighs.

Progressed?

What does that mean?

※

Sniff sniff.

What’s that? It smells like alcohol.

Could this be…

Suzune peeled the chocolate wrapper and took a bite.

“Hey, Suzune. Does that chocolate have alcohol in it?”

“Huh, but. I’ve eaten brandy bonbons before, so I’m fine.”

“Where’s the box for these?”

I looked at the chocolate box.

Then on the surface it said “sake chocolate.” Right below that it says “chocolate that brings out the flavor of sake.”

Since the lights were off, we apparently didn’t notice the difference.

At that moment.

“Beep! Suzune-san. Do you need something?”

Suddenly loud volume came from the TV.

“Kyaaaa!!”

Suzune jumped up and pressed her body against me.

Her sweaty skin touches my right shoulder.

“It’s the AI voice. You’re too surprised.”

When I said that, Suzune separated her body slightly and looked down.

Our fingertips are touching.

If anything, Suzune’s fingers are warmer than usual.

Suzune brought her face closer.

“Hey, my head is spinning.”

“You ate too much chocolate.”

Suzune stopped her hand, but liquid dripped from the piece of half-eaten chocolate.

When the transparent droplet slid down to her chest and disappeared, Suzune opened the collar of her shirt to let air in.

“It’s somehow hot and sticky…”

Suzune’s eyes looking at me were glazed as if appealing for something, and her cheeks were colored cherry blossom pink.

I’m reflected in Suzune’s moist eyes.

Gulp.

I swallowed.

…Could it be, is this what “progressed” means?

※

—That night, a single memo handed over by Suzune.

Just one line: “I, she, tell U.”

T/N: For context, the line “I, she, tell U” is written in actual english, meaning the letter is written in english, it’s actually a misunderstanding in Suzune’s side. If you read and vocalize it yourself, it actually sounds like Aishiteru, which is the japanese for I Love You.
