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 41-42

Chapter 41

“Tendou-kun, can I talk to you for a sec?”

On the way home.

Mizuki-san and I were walking together when she suddenly stopped and called out to me.

“Wh-what’s up?”

“Tomorrow’s your date with Ayaha, but you better not do anything weird, okay?”

“I-I know. It’s just for the novel—”

“Yeah, gathering experiences. But if you go getting unnecessary ones, we’re done. Like, over.”

Mizuki-san’s face was dead serious.

By the way, we decided the date order with rock-paper-scissors—Ayaha tomorrow, Mizuki the day after.

Maybe she didn’t like that result, or maybe she’s not actually that close with Ayaha, or maybe she’s just worried I’ll do something dumb because she cares about me.

Either way, she was in a really bad mood.

“I-I swear I won’t do anything.”

“Even if Ayaha comes onto you?”

“I-I don’t think she’s that kinda girl.”

“Well, I’d love to slap a GPS on you, but that’s too much, so I’ll hold back. Just report everywhere you go, step by step. If it’s turning into a boring date, I’ll give you instructions from here.”

“O-okay, got it.”

The air stayed super tense. When we got to her house, Mizuki-san said,

“I’m not gonna lose.”

Her face looked kinda sad somehow when she said it.

❤︎

“I’m home~”

“Welcome back, Mizuki. Sorry I skipped club today.”

“It’s fine. Thanks to that, I got to talk with Tendou-kun real slow and nice.”

“Hmm. So how’s the novel going?”

“Eh, decent enough. But Ayaha’s still—”

Blah blah blah.

I told Yuzuki everything that happened in the club room today, and her expression changed right away.

“Can I join in on that date thing too?”

“Huh? Why would you?”

“It’s about getting his experiences from dating different people and putting it in the novel, right? Then the more the better.”

“No, we’re not writing some harem story.”

“Even so, it’s normal to have like three heroines at least.”

“But—”

“Anyway, Tendou-kun’s not Mizuki’s or Ayaha’s boyfriend, so there’s no real reason to say no.”

Yuzuki said it all straightforward, and the vibe around her felt totally different from usual.

“…Something happen?”

“Nope. I just don’t wanna have regrets either.”

“Ohhh, so you’re finally motivated. Fine, as your twin, I’ll let it slide.”

“You’re being awfully understanding.”

“Not really. My little sister finally being honest with herself? As the big sis, I’m genuinely happy about that. And part of why you ended up like this is my fault anyway.”

“Mizuki…”

“But I’m not losing. Who knows—maybe after my date with him, stuff happens and your turn never comes. Hope you can forgive me if that happens.”

“I’ll pray it doesn’t come to that.”

When Yuzuki smiled, it made me happy too.

Deep down, I’d always felt like it was my fault Yuzuki couldn’t trust guys anymore.

Like, if I hadn’t fallen for that creepy senior back then, maybe Yuzuki could’ve had a normal high school life.

That foggy guilt just cleared up a little.

All thanks to Tendou-kun.

He really is like the sun to me.

“Okay then, Yuzuki. Tomorrow’s gonna be kinda lonely for both of us, but let’s hope Ayaha totally bombs.”

I said that and headed back to my room.

Right away, I fought down the urge to message Tendou-kun and opened my laptop instead.

Our page.

His and mine.

This private little space just for the two of us.

He’d uploaded another draft already.

I gotta hurry and edit it, polish it up, get the story far enough along so we can start posting soon.

Amatsuki.

Our names blended together—such a pretty pen name.

Just looking at it makes me melt, and every time I read it, I get this shiver.

Right now, I’m definitely the closest to him.

No way I’m losing to Ayaha—or to Yuzuki.

I won’t lose.

Well… maybe just this once.

I’ll turn a blind eye to this whole date thing, but that’s it.

This is your first—and last—chance.

“Seriously, Tendou-kun… it’s gotta be me. No one else.”

Chapter 42

♤

“From Yuzuki-san?”

It was night.

My phone suddenly rang.

“Hello?”

“Uh, hello? Tendou-kun? G-good evening.”

“What’s up?”

“Um, uh…”

She paused for a second, then kinda shouted it out.

“Hey, go on a date with me too!”

“…Huh? A date?”

“Ah—no, wait, that’s not—I mean, yeah, but! Mizuki told me about it, y’know.”

“Oh, you heard? Yeah, it’s for the novel. Tomorrow I’m going with Ayaha-san.”

“And the day after is with Mizuki, right? So the day after that… wanna go somewhere with me?”

“Y-yeah, sure, of course. Did Mizuki say something to you?”

“K-kinda like that. Anyway, just keep that day free, okay?”

She said that and hung up real quick.

“…A date, huh.”

I never thought Yuzuki-san would suddenly ask me out like that, so I was pretty shocked, but… she probably just wants to help with the writing in her own way.

Mizuki-san and Ayaha-san seemed to be competing on their own somehow, but what about Yuzuki-san?

Would she even have fun going on a date with someone like me?

…No, thinking stuff like that while on a date would be kinda rude to her.

Things got weird fast, but anyway—tomorrow first.

…I wonder where Ayaha-san’s gonna take me.

♡

“Haa… guess that’s about it.”

I’m still nowhere near being totally honest, but for me, that was pretty brave.

I probably surprised him by blurting it out like that.

He said yes to the date, though.

Going out with someone like me might not even be fun for him… but thinking that feels kinda rude to Tendou-kun.

…Where should we go?

Lemme search.

“First date… where to go”

♤

“Tendou-kuuun!”

Right after school ended, she was waiting at the main gate, waving big as she came over.

“Hey, good work today, Ayaha-san.”

“Ugh, why so formal? It’s a date—drop the polite stuff already?”

“Y-yeah, you’re right. So… where we headed?”

“Leave it to me. I’ve got this killer spot.”

And just like that, the after-school date plan kicked off.

I followed Ayaha-san and we turned into this narrow alley I never usually go down.

“Uh… it’s kinda dark around here.”

“Don’t get all paranoid. There’s a really good place just a little farther.”

A bit farther down the empty, shadowy alley, one single lit-up sign appeared.

“BAR Aya… wait, BAR? Like, a bar for drinking!? No way, we can’t go there.”

“We’re not drinking alcohol, duh. Their pasta is seriously amazing.”

“B-but… can high schoolers even go in?”

“It’s fine, it’s fine. Trust me.”

She opened the old door without hesitating and walked right in.

I stood there alone for a second, stressing hard.

Walking into a bar in uniform—if a cop sees us, aren’t we getting picked up?

Ayaha-san’s hair is pretty light too… maybe she’s kinda delinquent…?

“Hey, come on already~!”

She poked her head back out the door and yanked my hand hard.

“W-whoa, wait—oh wow.”

Inside it was dimly lit, but candles lined the counter, giving this soft glow.

Rows and rows of fancy bottles behind the bar.

Thick, expensive-looking carpet.

It looked like something straight out of a movie or drama—this whole adult world—and I couldn’t help letting out a little sound.

“Pretty cool place, right? Come on, sit at that counter seat over there.”

I did what she said and sat at the end of the counter.

Ayaha-san headed straight to the back of the shop.

She seemed super used to this place. I got even more nervous, fidgeting in my seat, when—

“Papa! I brought a customer~!”

A voice called out, and this super handsome older guy in a suit came out from the back with Ayaha-san.

“P-Papa?”

“Hehe, yeah—this is my house.”

“Huh?”

“Haha, good reaction. This is my dad’s bar, and we live right upstairs.”

Ayaha-san sat down next to me, grinning. The handsome guy stepped behind the counter and stood right in front of me.

“So you’re the one who helped Ayaha the other day.”

“Uh, h-helped is kinda exaggerating. Um, well—”

“You can call me Papa if you want.”

“…Huh?”

“Ahem, kidding. I’m Ayaha’s dad, Toru.”

“Uh, hi—I’m Tendou Asuka, Ayaha-san’s classmate.”

“No need to be so nervous. I heard my daughter was bringing her savior, so I closed the place for the night—just us.”

Ayaha-san’s dad stroked his neat goatee with a small smile, then smoothly pulled out two glasses, dropped ice in them, and poured orange juice.

“Ah—thank you.”

“I’ll whip up some food too, so just hang tight.

Enjoy yourselves.”

Ayaha-san’s dad disappeared into the back again.

“Hehe, were you nervous?”

“Y-yeah, obviously. But… your dad’s really cool.”

“Suave, right? He’s super nice too—looks intense but he’s actually pretty chill.”

“B-but, uh… is this really okay?”

“Ugh, still worrying? It’s my house, dude.”

“That’s exactly why. Even if we’re just classmates, I’m still a guy.”

“Ohhh, that kinda thing? My parents are chill about it. Working nights, you meet all kinds of people anyway.”

“O-oh… right. Um, I might need the bathroom real quick.”

“Oh, it’s back that way.”

She pointed me to the restroom in the back of the shop.

I went, did my business, and finally took a breath.

“Haa… still super tense.”

But man, this is an amazing experience.

If Ayaha-san hadn’t dragged me here, I never would’ve stepped foot in a place like this until I was way older.

The novel’s set with college students right now, so today I’m gonna soak up as much as I can.

“Ayaha, he seems like a pretty serious kid.”

“Right? He looks kinda unreliable at first, but when he helped me out the other day? Super cool.”

“Still waters run deep, huh. Alright—Papa’s gonna go all out to help.”

“Mm-hmm, thanks!”

Getting Tendou-kun to meet Papa right away was a success.

Papa’s a pro at this—he’s really good at steering conversations wherever he wants.

Our bar’s got a rep for being great for couples—people say if you come here with someone you like, it works out easy.

And it’s not just the vibe or the drinks.

Papa’s skills make a huge difference.

So yeah… me too.

“Tendou-kun, I’m not letting you go home tonight.”
