Somehow I Ended up Dating the Perfect Female Classmate, but My Sister Found Out and They're Turning Into Yanderes - Chapter 8-9

Chapter 8: About Leftovers

“I’m back!”

“…”

Ayuka’s cram school ended, and we both returned home.

I said “I’m back!” loudly enough for Rinka and Fuzuha to hear, but Ayuka stayed silent.

Is this her middle-school rebellion phase?

We enter the living room to eat dinner.

“Hey, Rinka, is it ready…?”

“…”

In the living room, Rinka stands with an intense aura.

Next to her, Fuzuha looks like she wants to sigh.

“Uh… Rinka-san? Is something wrong…?”

I clasp my hands nervously and ask.

“Hey, Kiyoto.”

Oh, she’s mad at me, not Ayuka.

“Stay after dinner. We need to talk.”

Rinka orders me to stay without hiding her anger.

…Looks like my death sentence is confirmed.

From then on, we eat in complete silence.

Silent meals are normal, but today, not a single sound is heard.

No slurping of miso soup, no scolding from Rinka about bad manners.

“…Thanks for the meal.”

It took me forty minutes to finish eating today.

Our house rule requires everyone to stay until all finish eating before clearing the dishes, so we all stayed for nearly forty minutes.

But today, neither Ayuka nor Fuzuha complains about my slow eating.

And no wonder.

Rinka, sitting across from me, radiates burning anger, so no one dares speak.

When I finish, Ayuka and Fuzuha quickly clear their dishes and head upstairs.

Tch! Heartless sisters.

Don’t they care about protecting their brother?

“Kiyoto, come to the kitchen.”

…Facing Rinka right now is impossible, though.

“Now, explain this.”

In the kitchen, Rinka’s bento from today sits untouched.

…I’m done for.

“Didn’t you hear me say explain…?”

“Uh, well, today my stomach was completely full, you see…”

“…”

Rinka crosses her arms, glaring at me with piercing eyes while silently listening.

She’s listening, but I feel she’s not convinced at all.

“So, it’s not that your bento didn’t suit my taste. I just ate too many snacks from the school shop before lunch break.”

“I see. Snacks.”

She finally speaks, but her voice proves she’s still angry.

“So, the bento I poured my heart into before morning practice is less than snacks to you?”

Saying “poured my heart” makes me hesitant to eat it from now on.

“Just kidding. I felt sick all day and stayed in the bathroom, so lunch break ended before I noticed.”

“You didn’t go to the bathroom once during dinner.”

“I suddenly felt better after coming home. Must be because my sisters are here, calming my mind and fixing my stomach.”

“…”

Her expression doesn’t change at all.

I thought that would soften her up…

“Fine. I’ll let it slide today.”

“Let it slide” sounds odd, doesn’t it?

“If you were full from snacks or ate someone else’s bento, I’d have dealt with you.”

What!?

No way she knows, right?

And what does “dealt with you” mean!?

“That’s all. If you have no other business and don’t feel like helping with the dishes, go to your room.”

Isn’t she basically forcing me to help with the dishes?

Since I’m clearly at fault today, I help without complaining.

While washing, I notice Rinka looking sad for a moment, so I decide not to tell her I don’t need her bento anymore.

Chapter 9: Do-M Game

“Should I study a bit?”

I came out of the bath and now stare at my study desk in my room.

Being a third-year high school student, I wondered if I should study before bed.

“Well, I went to observe the cram school today, so maybe I can skip it.”

Observing is proper learning.

Besides, I observed for an hour and twenty minutes, so some content probably stuck in my head.

“But there’s still time before bed.”

I look around my room for something to kill time.

“Oh, there’s something good.”

My eyes land on a game disc on top of the console next to the TV.

I bought it because it was hyped as a “Do-M game,” but it turned out to be a different kind of Do-M game, so I quit at the tutorial.

“Normally, ‘Do-M game’ makes you think of a gal game, right? Why is it a death game?”

I’m a bit of a masochist, but I don’t get excited over unfair games.

“…Should I play it again…?”

I heard that people good at games often have sharp minds.

So, if I beat the first boss of this death game now, it might help with my exams.

“It’s designed for you to die anyway, so let’s try it for fun.”

With that decided, I press the power button on the console.

After it lights up, I insert the game disc.

“Was the controller always this hard to use?”

I’ve been playing PC games lately, so I’m not used to the controller.

I move the controller and press start.

“This title logo screams it’s not a gal game…”

They should make a medieval Europe-themed gal game sometime.

“Ugh, I didn’t even save the last tutorial. How quickly did I give up?”

I press new game, and a story opening video starts playing.

…The graphics are too crisp.

Also, the subtitles are annoyingly small.

When the opening ends, it switches to the protagonist’s perspective.

The graphics are sharp, but the movement feels sluggish.

“Okay, triangle to crouch behind the enemy… Wait, what!? This game’s NPCs have crazy instincts!”

After the basic movement tutorial, I enter stealth mode, but the enemy turns around, spots me, and it’s game over.

Apparently, my footsteps gave me away.

You can die in the tutorial!?

“You jerk!”

I try again, taking ten minutes to creep behind the enemy, and successfully ambush them.

“…Huh?”

Just as I brace for the next tutorial, a huge boss-like enemy appears.

“No way, a boss fight tutorial!?”

It appears so suddenly I can’t create distance, and its long axe hits me, draining my health instantly.

“…Isn’t this too much of a blind kill…?”

I try again, but the axe swings too fast to dodge, and I die again.

And again, and again, and again.

No matter how many tries, I can’t dodge the axe.

“Ugh, forget it! I’m done!”

The difficulty is so unfair I reach to unplug the power cord.

“Hey, big brother! You’re being loud!”

Fuzuha storms into my room in pajamas, yelling.

“Oh, s-sorry. I got carried away.”

Fuzuha’s room is right next to mine.

So, she heard my desk-smacking and shouting clearly.

“…Big brother, you’re playing games this late?”

You’re an exam student, she says, approaching the TV.

“Wait, isn’t this that death game that was trending!? You’re playing this?”

“Well, I bought it, so I thought I’d kill some time…”

“No way you can clear a game this hard, big brother.”

Yes, indeed…

“Give me the controller.”

“Huh?”

“I’m saying I’ll play it for you.”

“Okay, but… can you even play?”

“You don’t know, but I’m pretty famous as a gamer at school. During lunch, we play fighting games, and I always crush everyone.”

Middle schoolers playing games at school…

If Rinka finds out, it won’t just be physical punishment.

“So, you’re stuck on this tutorial boss?”

“Yes, Professor Fuzuha, please take care of it!”

“P-Professor… Being called that by you isn’t bad…”

After that, Fuzuha focuses on the game and stops talking.

She stares at the screen seriously.

Even if she’s good at games, beating it in one go is impossible.

Sure enough, Fuzuha dies a few times.

But unlike me, she doesn’t curse or slam the desk; she calmly analyzes why she died.

This kid’s kinda cool.

It took nearly forty minutes, but she finally beats the tutorial boss without taking damage.
