Somehow I Ended up Dating the Perfect Female Classmate, but My Sister Found Out and They're Turning Into Yanderes - Chapter 101-102

Chapter 101: Kirino Has Changed

“…Oww, oww, oww…”

The pain in my neck is still shooting through me.

This morning Kirino spotted the bite mark on my neck, found out Satsuna did it, and while shaking with anger she dug her fingers into my neck.

That mark stayed super clear too, so during the opening ceremony I couldn’t take it anymore and ran to the nurse’s office. I just finished getting the bandage wrapped.

“Hey, Kiyoto. You ditched the opening ceremony—where’d you go?”

When I got back to the classroom, Kouta was the first one to call out to me.
Well, he’s pretty much the only person who talks to me, so that makes sense.

“Nah, my neck was hurting a bit…”

“Your neck? Wait, don’t tell me that’s from Kirino—”

“Kiyoto!”

Kouta’s words got cut off as Kirino jumped right in.

“Is your neck okay!?”

“Y-yeah, they just wrapped it with a bandage and that was it.”

“Oh, good… Sorry, Kiyoto. I got so mad I put too much strength in my fingers.”

…Honestly, Kirino’s finger marks were way clearer than Satsuna’s bite.

“Oh, by the way—”

Kirino suddenly turns her eyes to Yoshirin standing next to her.

“You still haven’t made Kiyoto apologize for that thing, right, Yoshirin?”

That thing…?

Oh, right.
The time she snuck photos while I was relaxing at Kirino’s house.
And then sold those pictures to Satsuna.

“Come on, Yoshirin. Say ‘I’m sorry’…”

“……”

Even though Kirino ordered her to apologize to me, Yoshirin just grimaces and doesn’t say a word.

“Did you not hear me~? Come on, ‘I’m sorry’?”

“Guh!?”

Right then Yoshirin’s face twists in pain.

“Hey, Kikujima, what’s wrong?”

“Can you stay out of this, Kouta? This is a problem between the three of us, so I’d appreciate it if you didn’t butt in.”

He was just worried about her and he gets treated like that.
Tough luck, Kouta.

But why does Yoshirin look like she’s in so much pain…

A bad feeling hits me and I glance down at her feet.

Oh… Kirino is completely stepping on Yoshirin’s foot.
And she looks like she’s putting a lot of weight on it too.

Kirino… could you please stop stepping on Yoshirin’s foot?
You can step on my head instead.

“S-sorry…”

“What was that~? I can’t hear you, Kiyoto~?”

“!?”

Ah, she probably just put even more weight on the foot she’s stepping with.

I think the main reason Yoshirin can’t properly apologize is because the pain is making it hard for her to speak, though her pride is probably part of it too.

Also, Kirino… people around us are starting to look a little freaked out…?

“I-I’m sorry!”

Yoshirin apologizes desperately, like a kid getting spanked by their mom.

Hey, don’t get the wrong idea—I’m not the one making her apologize, okay!?

“Yeah, Yoshirin said it too… so can you forgive her, Kiyoto…?”

No, like I keep saying, I never told her to apologize in the first place!?

“N-no… you don’t have to apologize that much… is your foot okay…?”

“…I’m fine… thanks for worrying about my foot, I guess… guh.”

“…Hey, Yoshirin. Kiyoto is kindly worrying about you, so what’s with that rude attitude?”

This time Kirino squeezes Yoshirin’s shoulder hard.

“…Th-thank you for worrying about my foot…”

Her face doesn’t look thankful at all.

In moments like this, what am I supposed to say—

“Huh? Kiyoto isn’t saying anything… so I guess he still hasn’t forgiven you. In that case, Yoshirin, keep going until Kiyoto says it’s okay.”

“W-wait, Kirino, stop! I already forgave her a long time ago!”

“…Really? You’re not just forcing yourself because you feel sorry for Yoshirin, right…?”

“I honestly forgive her! So please let go of Yoshirin.”

“Got it. If that’s what you want, Kiyoto, I’ll let her go… There, Yoshirin. Kiyoto forgave you. Now say thank you.”

“No, you don’t have to!”

If this keeps going Yoshirin’s really gonna end up broken beyond repair.

She likes Kirino enough to sneak into her house to try to break us up, and now the same girl is threatening her like this. Her mental state must be a total mess.

“…Hey, is that really Kinui…?”
“Our angel… our angel has fallen and become a fallen angel…!”
“Poor thing… she probably got trained by that masochist guy…”
“But violent Kinui is kinda hot too…”

See, Kirino? The peanut gallery is saying all kinds of stuff.

And there’s no way I trained Kirino!
It was the other way around—I got trained!
I almost got stolen by other girls who trained me thoroughly.
Actually, I did get stolen!

“Ah, looks like the teacher’s here. Hey, Kiyoto, your seat’s next to mine, right? Hurry up and sit.”

Kirino completely ignores all the weird looks and whispers around us and pulls me to our seats.

…With a start like this, is the second semester really gonna be okay…?

Chapter 102: About the Sports Festival

“You third-years, this second semester is the real battle.”

In homeroom the teacher is just saying the usual obvious stuff.

Speaking of exams, I wonder if my classmates actually studied hard over the summer.
After the opening ceremony the class was noisy, but I didn’t hear a single word about studying for exams.

Well, this school doesn’t even call itself an advanced school, so I guess it makes sense.

“Also, right after this semester starts we’ve got the sports festival coming up.”

Oh yeah.
Our school holds the sports festival in September.
I wonder if only the third-years get excused because of exam prep.

Do we even need a sports festival?
It’s just an event for the outgoing sports-club kids.
Though in this school most people are super unmotivated, so it doesn’t even feel like it’s for the outgoing kids.
It never gets that lively anyway.

“It’s technically a class-versus-class thing, and the events are listed on the blackboard.”

What’s written there is:

Everyone-participation 100-meter dash.
Ball toss.
Big jump rope.
Tug-of-war.
Three-legged race.
And the class-representative selected relay (200-meter dash).

Whoa, aren’t there more events than usual this year?
Wait, you think that’s still few?

Nah, maybe it seems few for a normal lively high school, but remember this is Joto High.
The shadow-person manufacturing machine high school.
Yet if we ever do a school camping trip, tons of guys end up locking themselves in toilet stalls at night to let out their pent-up desires.

Just keep that in mind.

“So, uh, from today until the day of the sports festival you’re allowed to practice on the field after school… but whether you actually do it or not, decide for yourselves.”

…The teacher clearly doesn’t care either.

And today we finish at lunch, so if we do practice it won’t even be that long.

……

Nobody really has any opinion, but I bet everyone’s thinking the same thing inside.

We don’t have to do it, right?

The teacher must’ve felt that too, because

“Well then, let’s take a break for now.”

He ended homeroom early.

“Hey Kiyoto, you wanna practice?”

The second break started, Kouta was the first one to talk to me.

This guy talks to me even faster than Kirino does…

Wait, is he into that…?

“You already know my answer, right?”

“Yeah, I figured, but you’re probably—actually definitely—getting in on recommendation, so you’ve got more free time than the regular kids. I thought maybe you’d be up for practicing.”

Sure, I’ll have more free time than the normal students, but if I’m gonna use that time for anything, I’d rather spend it researching my own dick than practicing for the sports festival.

“Plus you got yourself a girlfriend now, so I figured you might betray us bros and throw away all your masochist doujinshi to try forcing yourself to become an outgoing guy.”

“There’s no way I’d throw away the means to release my own desires, right? Especially not to my fellow comrades.”

“Fellow…?”

“Ah, no… I mean, there’s no way I’d betray my comrades like that.”

I pat Kouta on the shoulder to reassure him.

“Hearing that puts my mind at ease. I was worried you’d changed your own kink.”

“Everyone, listen up!”

Kouta’s words got cut off again, this time by Kirino.

“You know… even if exam studying is busy, I think we should still practice for the sports festival.”

The whole class looks confused by Kirino’s sudden announcement.

“This is our last sports festival in life, right? So instead of half-assing it, I want us to practice seriously and show off everything we’ve built up through PE until now.”

…I don’t have anything built up from PE.

“That way it’ll definitely become a great memory, and we’ll feel glad we were in this class.”

Kirino’s saying some pretty cheesy stuff.
Well, the real Kirino isn’t a DV girlfriend—she’s the type who says things like this in front of everyone, I think.

“Right? You think so too, don’t you, Yoshirin?”

Kirino walks over to Yoshirin’s seat a little farther away.

“I-I…!?”

“Come on, you think so too, right?”

I take it back.

The real Kirino really is a DV girl after all.

She’s probably standing right next to her, but I can’t see her hand, so she must be yanking Yoshirin’s hair from behind.

“I-I think so too.”

“Yeah, see? Yoshirin said it too, so everyone else thinks the same, right?… You do, right?”

““““““““““““Y-yes!!!!!!!!””””””””””””

Kirino’s voice carries heavy pressure, and everyone gives in and answers.

And so, thanks to Kirino’s reign of terror, our third-year D class ended up deciding to practice after school until the sports festival.
