Somehow I Ended up Dating the Perfect Female Classmate, but My Sister Found Out and They're Turning Into Yanderes - Chapter 60-61

Chapter 60: An Intercom That Means the End

““““……””””

Not a single person spoke, and silence filled the living room.

We had just finished eating dinner.

It was about a day since yesterday’s shocking announcement.

Today, Ayuka ate dinner at home too, but during the meal, just like now, no one said a word.

And no wonder.

In just a little while, that tyrant Satsuna would return.

Satsuna is one year older than me, and we lived together in this house until I entered my second year of high school.

After graduating middle school, she went to Shinkai Girls’ Academy, one of the top elite girls’ schools in the country.

Shinkai Girls’ Academy is quite far from here, too far to commute, so she now lives in the dormitory.

Huh? Wasn’t it a super serious atmosphere when Satsuna left home?

Didn’t Fuzuha cry and throw a tantrum or something?

Well, that’s not how it went.

That day when Satsuna left home (honestly, I barely remember it),

everyone acted sad, but it was obviously fake.

Didn’t Ayuka even make a small fist pump halfway through, unable to hold it in?

Rinka, with her personality, didn’t show any joy, but her eyes were completely cold when she saw Satsuna off.

Fuzuha might have been genuinely a bit sad, not just acting, but at least she didn’t cry.

As for me, I don’t remember much, so I was probably fighting sleepiness or something?

Anyway, it’s hard to say Satsuna was loved by us.

The reason? Her personality, of course.

Being the eldest daughter, she observed her younger sisters as much as Rinka did and was very responsible.

But she always made snide remarks.

In simple terms, she gave off a strong vibe of looking down on people.

Her refined, lady-like way of speaking and that mocking smile of hers were big reasons for it.

Unlike those rich mom friends in satisfying manga or Line stories online, Satsuna is extremely talented.

Her looks rival any girl around me, and she’s top-class in both studies and sports.

In daily life, no matter how hard you try to find a flaw in Satsuna, she’s so perfect that you end up accepting her superiority, even if she looks down on you.

But Rinka probably felt a lot of humiliation from Satsuna.

To me, Rinka is plenty perfect, but compared to Satsuna, she falls just a step behind.

Everyone knew it, including Rinka herself.

And, of course, Satsuna knew it too.

Satsuna often said things that hurt Rinka’s pride, and since her words always hit the mark, Rinka couldn’t argue back.

Maybe Satsuna just meant to tease her serious, cute little sister a bit, but it definitely clouded Rinka’s self-esteem.

To overcome that inferiority complex toward her older sister, Rinka threw herself into kendo.

Ironically, Satsuna’s actions ended up helping Rinka grow, but I’ve recently started wondering if Satsuna planned it that way with her harsh words… Nah, with her personality, that’s probably not the case.

With the eldest daughter gone, Rinka basically took control of the house, setting even stricter rules than before.

As the lowest in the family hierarchy, she treated me like livestock.

It was like something straight out of an SS story tagged with “perfect for masochists,” and it transformed “me” into the “me” now.

“…Hey, is Satsuna-neesan really coming back now?”

Ayuka still doesn’t seem to grasp the reality.

When I told Ayuka, who came home late last night, that Satsuna was returning tomorrow, she lazily said,

“What? Is this revenge for that forced kiss before? If so, come up with a more believable lie.”

She clearly didn’t believe it, but Fuzuha and Rinka must have told her too.

During and after dinner, she kept her head down, apparently still unable to face reality.

“…Ayuka, accept it.”

Rinka’s regretful murmur seemed to finally wake Ayuka up, and her face darkened.

Even Fuzuha, who looked so relieved yesterday, now seems awkward, realizing the weight of what she’s done.

And me? I’m just imagining what’s about to happen, my desires going up and down like a rollercoaster.

But in that moment, the intercom rang, putting an end to it all.

Chapter 61: The Queen’s Return

“Oh, it’s been a while, Rinka.”

“…Welcome back, Sister.”

The moment the interphone rang, Rinka rushed to open the front door.

She’s totally turned into a servant.

“Is everyone in the living room?”

“Yes, everyone’s here…”

A voice like one from an adult audio drama, all refined and ladylike, came from the entrance.

““…””

As Satsuna’s footsteps got closer, everyone’s faces stiffened.

Then, the living room door slowly opened.

Long legs in black tights, a black-purple uniform that screams high school girl, and long, silvery-white hair.

She’s about as tall as Rinka, with slightly larger-than-average breasts.

And above all, a face so refined that anyone would agree she’s the elegant type.

That’s Satsuna Nuregami, walking in.

“It’s been a while, Ayuka and Fuzuha. And…”

Satsuna turned to me, flashing a dazzling smile.

What is it… Her smile is so perfectly villainous, it’s making my “son” lose control.

“I’m back, Brother.”

…As usual, she only uses that super ladylike tone when talking to me.

Not that I mind, though.

“Welcome back, Satsuna-nee.”

“…Satsuna-neesan, welcome back…”

Both of them stood up to greet her.

Even Ayuka didn’t make a single annoyed face.

“Fuzuha, I noticed it over the phone, but your voice has changed a bit. You’ve grown taller too, haven’t you?”

“But my classmates still call me a little kid.”

Oh, she notices stuff like that?

“And Ayuka… Have you started wearing a bit of makeup?”

“N-No, just a little, just a little!”

Huh? Ayuka was wearing makeup?

I’ve been with her so long and didn’t notice, but Satsuna picked it up in a second.

Total defeat.

“And Brother… Heh, you haven’t changed at all. Or rather, have you gotten even shorter?”

Hmph, I’m used to height jabs.

No matter how much she teases, it doesn’t hurt or itch—it just becomes “nutrients” for me, so it’s pointless.

“Oh, not just your height, but your face looks even more pathetic than before… No, wait, it was already plenty pathetic, so it’s a wash, isn’t it?”

…That one stung a bit.

What does “pathetic face” even mean?

If it’s about looking young, that’s more fuel for me, but if it’s about looking old or just plain ugly, my “son” might starve.

“So, Sister, what’s the reason for today’s visit…?”

Rinka, who came in after, cut in.

“Oh, right. I’ll play with Brother later, but I came back today to talk about some things.”

Satsuna looked around.

Noticing this, Rinka quickly placed a chair right in the center.

Seriously, she’s totally a servant.

Is this what they call “tamed”?

Satsuna sat down, crossing her legs.

There it is—the sitting pose that excites me (us).

Once Satsuna sat, everyone took their seats.

“Yesterday evening, I got a call from Fuzuha at the dorm. She said your relationships have been strained lately and asked me to mediate.”

This is not the attitude of someone mediating.

“What’s going on, Rinka? I thought you were in charge of this house now, and I told you to handle it that way.”

Told her, meaning she ordered her.

Questioned by Satsuna, a slight sweat appeared on Rinka’s forehead.

Rinka, who didn’t sweat even after intense exercise in the heat.

“…I have no excuses. If Fuzuha feels that way, it means I haven’t been diligent enough.”

“I’m not asking about Fuzuha. I’m asking how you feel about the state of our sibling relationships.”

Her tone didn’t change, but Rinka must have felt the slight increase in pressure.

“I feel the same as Fuzuha. I admit there’s a rift in our sibling relationships lately, and I recognize it’s my responsibility.”

“I see. You’re aware. Then explain exactly how you’re responsible.”

The pressure’s getting heavier.

It’s only because it’s Rinka. If it were me being questioned, I’d either wet myself or my “son” would rip through my pants.
