The S-Class Beautiful Sisters at My New School Somehow Got Super Attached to Me and Ended Up Becoming Yandere Without Me Even Realizing It

Chapter 6

“I’m home—”

“Welcome back, Mizuki. How’d it go?”

Mizuki came in with her ponytail, but the second she got home she let her hair down and looked kinda worn out.

“Haa… I dunno, it was weird.”

“What’s that supposed to mean? Don’t tell me your cover got blown?”

“Not blown, exactly, but he definitely felt something was off. Hey, are you actually that close with him?”

“Me? Not at all. If anything, you talked to him first.”

“Yeah, true. Hmm.”

This might be the first time I’ve ever seen Mizuki thinking this hard.

But honestly, ever since I met him, I’ve been feeling the same kinda way.

“Hey, tomorrow let me talk to him.”

“Which version of you?”

“My normal self, obviously. So what’d you guys talk about today?”

“Umm… like why he transferred here, why he’s not joining any clubs? Oh, and I kinda asked if he had a girlfriend.”

“You asked that?!”

“Well, he was being so indifferent and didn’t ask anything about us. But he doesn’t seem totally uninterested in girls or anything.”

“…Awkward.”

“Huh? What?”

“Asking something like that just makes it sound like I wanna date him or whatever.”

“Does it?”

“…Whatever, it’s fine. I’ll smooth it over tomorrow.”

Smoothing over my own mess sounds weird, but whatever.

Mizuki’s always taking care of stuff for me anyway, so I can’t really complain.

…But I better text Tendou-kun later and tell him not to say anything weird when I’m in my real look.

“…Ugh, so tired.”

The second I got home I collapsed onto my bed.

“What was that about anyway?”

Why’d she suddenly ask if I had a girlfriend?

No way Yuzuki-san’s actually interested in me… nah, that’s pushing it.

Maybe she was just being nice to the new transfer kid, or scrambling for something to talk about.

More importantly though…

“…Was that really Yuzuki-san earlier?”

For some reason, the girl from before didn’t feel like Yuzuki-san at all.

But why would Mizuki-san bother switching with her sister just to walk home with me?

…No clue.

I don’t even have solid proof they were switching anyway.

“Haa… this is so confusing.”

◇

“Uh, morning.”

Morning.

On my way to school someone called out from behind me.

I turned around—and there was Aoyama Yuzuki.

“G-good morning.”

“…Thanks for yesterday.”

“N-no no, I didn’t really do anything worth thanking.”

“Y-yeah, true. But still… sorry for asking something weird.”

She scratched her cheek awkwardly and wouldn’t quite meet my eyes, which somehow made me feel awkward too.

“Nah, it wasn’t weird or anything.”

“A-anyway… Do I seem different today compared to yesterday?”

“Different?”

She hit me with another random question out of nowhere, so I tilted my head.

But when she said “different,” I didn’t really notice anything…

“Hmm…”

“So you can’t really tell?”

“Um… did something good happen?”

“Huh? What do you mean?”

“Ah, no, it’s just… like, you seem brighter today? More natural or something.”

Just a gut feeling.

But yeah, the weird vibe I got from her yesterday after school wasn’t there at all.

“Natural… huh.”

“I-I mean, I could be wrong. Did I get it wrong?”

“No, it’s fine. Anyway, I’m heading in first.”

She looked down like she was thinking hard, then walked off ahead of me without another word.

Chapter 7

♡

“Ughhh, why am I getting all nervous like an idiot!”

Once I was alone, I grabbed my head with both hands.

Yeah, it was kinda awkward, but more than that I just couldn’t stay calm.

My face felt all hot and embarrassed, my whole body was heating up.

…What even is this, seriously.

“Got a nice little show first thing in the morning.”

“M-Mizuki? Since when were you there?”

“Hey, you’re the one who said ‘follow from far away,’ remember?”

“Y-yeah, true, but… um, did you hear the whole conversation?”

“Kinda, bits and pieces. What was that? You falling for him or something?”

“N-no way! I’m not falling for him! It just got awkward ‘cause you asked that weird question yesterday!”

“Yeah yeah, sure, whatever you say. So… looks like Tendou-kun might’ve noticed our switch after all?”

“…Probably. He seemed to feel something was off somehow. No clue how he could tell, though.”

“Hmm, interesting. Yuzuki, go get closer to him anyway. We need more intel on him. You’re classmates, right?”

“Why are you so into this? Wait… don’t tell me you’re the one who’s actually interested in Tendou-kun?”

“No way. I just wanna know if there really is a guy who can tell us apart without relying on looks.”

“Well… yeah, I agree with that. If someone like that actually exists… nah, too early to get my hopes up.”

Right. Nothing’s confirmed yet.

But one thing’s for sure—he’s different from every other guy I’ve ever met.

Maybe… just maybe… he’d actually see me properly too…

♤

“Yo Asuka, I saw everything.”

The second I got to school, Nakanishi came right up to me with this kinda scary look.

“W-what do you mean?”

“This morning. You walked with Aoyama Yuzuki, didn’t you.”

“Huh? You saw that?”

“Yeah, during morning practice I was running on the other side of the river. So what’s up with that? Don’t tell me you and Aoyama—”

“N-no, no, it’s nothing like that! Total coincidence. Turns out our houses are kinda close or whatever.”

“Ohhh, that’s all? Lame.”

Nakanishi looked super relieved for no reason, so I decided to ask him something.

“Hey… that thing you told me about the Aoyama sisters before—was that actually true?”

“Hm?”

“Y’know, the hair thing. Hair down is Mizuki-san, ponytail is Yuzuki-san.”

“Oh yeah, that’s 100% real. They straight-up told everyone themselves ‘cause they hated getting mixed up.”

“They told people?”

“Yeah. Makes sense though—when they look that identical, nobody can tell without some kinda marker. Like, they could probably switch places and nobody would even notice.”

Right as Nakanishi said that, Aoyama Yuzuki walked into the classroom.

Ponytail.

So that really was Yuzuki-san earlier.

But… was it really?

Right now… I’m pretty sure it’s Yuzuki-san.

“Even if they switched, nobody’d know, huh.”

“Hm? You say something?”

“Nah, nothing.”

After Nakanishi went back to his seat, I watched Yuzuki-san chatting with her friends from across the room, but nothing really stood out.

She didn’t come talk to me or anything all day.

Then, right after the last homeroom period ended, Sensei called me over.

“Tendou, have you decided on a club yet?”

“Uh… do I really have to join one?”

“Look, I get that jumping in mid-year feels awkward. But unless you’ve got a special reason, everyone’s gotta join something here. How about the reading club? They basically just do whatever on their own.”

“Reading club…”

Pretty sure that’s the one the Aoyama sisters are in.

But I heard they’re both ghost members anyway, so if it’s just signing up and never showing up, that might be the easiest option.

“Okay. I’ll do reading club then.”

“Great. Fill out your name and the club on this form.”

He handed me the club entry sheet right there.

I wrote my name and the club, gave it back, and he handed me a key instead.

“What’s this?”

“Key to the clubroom. It’s at the far end of the third floor in the north wing. Lock up when you leave, got it?”

“Y-yeah.”

“Also, ghost member or not, at least show your face in there once.”

Sensei said that and left first.

“…Reading club, huh.”

I gripped the key tight and headed out of the classroom toward the north wing.

Yeah, Sensei kinda pressured me, but I was also just curious what this reading club room was even like.

I walked through the quiet, kinda dark school building until I reached the third floor of the north wing. At the back, there was a classroom with a sign that said ‘Reading Club.’

I went to put the key in the door—

—but when I touched it, the door rattled and moved.

“Wait… it’s not even locked?”

I muttered that to myself, then pushed the door open and stepped inside.

And then—

“Good work today, Tendou-kun.”

In the middle of the classroom—surrounded on every wall by bookshelves—stood a girl.

“Ah… Aoyama… Yuzuki-san?”

Ponytail, those big eyes—definitely the beautiful Aoyama Yuzuki.

“What’s with that face? Like you just saw a ghost. Am I bothering you by being here or something?”

“N-no, that’s not it at all.”

“Whatever. So you came here ‘cause you joined the reading club too, right? Then… looking forward to it, starting today.”
