Somehow I Ended up Dating the Perfect Female Classmate, but My Sister Found Out and They're Turning Into Yanderes - Chapter 14-15

Chapter 14: Self-Proclaimed Masochist Gamer Multiplayer With Her

“Ugh, I’m so tired from everything today.”

The oversleeping incident.

The bento incident.

The long-distance run with Rinka.

The sisters’ fight.

“With all these troubles making me tired…”

I looked at the workbooks on my study desk.

“…I can skip studying today too.”

It’s fine, it’s fine.

I’m in my third year, but it’s only June, so I don’t need to get serious yet.

I just need to make sure this doesn’t keep up and make me fail the entrance exams.

“Well then, before bed tonight…”

I remembered the fake masochist game Fuzuha played yesterday.

No, that game’s difficulty is way too high for me to play alone.

And I can’t call Fuzuha at this hour.

“…The only thing to do before bed is that.”

Not studying, but “nighttime studying.”

I put the tissue box from beside the TV on my bed.

“Now, what should I watch tonight?”

Come to think of it, I haven’t fantasized lately.

If I don’t fantasize soon, my imagination will start to fade.

I decided to search my mind for some usable fantasy.

Then, my phone’s notification sound rang.

“Hm?”

It’s an email notification.

“An email for me? From who?”

Well, there’s only one person it could be.

“Sorry, are you still awake?”

Kirino-san sent me a message.

“I’m still awake. I’m about to play a game.”

I recently learned it’s important to be honest instead of making myself look better.

So, instead of saying I was studying, I told her I was about to play a game.

Though, it wasn’t studying or gaming…

“A game? The one you said you played with your sister today, set in medieval Europe…?”

“Yeah, yeah, I’m about to play that one solo.”

Saying I’m gaming was a lie, but the “solo play” part was true.

“Actually, I’m really into that game too.”

“What? You, Kirino-san?”

I can’t imagine Kirino-san playing games, especially that edgy, masochistic one.

And this morning, when I mentioned it, she didn’t seem interested.

Could it be…?

Did she buy it today just to play with me!?

That game, with its insane difficulty, allows online co-op to help out.

“So, want to play together now?”

“Absolutely, yes! I’d love to play with you!!”

I answered instantly.

“Kirino-san, can you use the controller’s mic?”

“Mic? Where’s the mic?”

Did she buy not just the game but the console today for me?

That’s way too kind!

After that, she told me her account name, and we became friends.

When you add a friend, you can see when their account was created.

As expected, Kirino-san’s account was made today.

“Ah, ah, can you hear me, Kiyoto-kun?”

Kirino-san’s voice through the game was as beautiful as ever.

“I can hear you, Kirino-san.”

I wondered how my voice sounded through the game.

I heard game mics can add a voice changer effect, making your voice sound different, and I wanted to check if that was true.

“Kirino-san, have you cleared the tutorial yet?”

From watching Ayuka play yesterday, I knew you needed to clear the tutorial, or the story’s regular enemies and bosses would kill you instantly.

Since Kirino-san likely bought it today, I figured she was struggling with the tutorial boss.

“Yeah, I cleared it already.”

…Huh?

She bought it today and beat it today?

Also, she bought it today, but since she was with me all afternoon, she could only have gotten it at night.

“Uh, do you remember how many times you died in the tutorial’s final boss fight?”

“Hm, I don’t remember exactly, but probably within twenty tries.”

Within twenty tries!?

On the day she bought it!?

She’s crazy good.

“W-Wow. Then can we play multiplayer with my save data?”

“Yeah, I want to help you out, Kiyoto-kun.”

…It seems even in the game, she’s the one leading me.

Of course, in my fantasies too.

Chapter 15: Turning Tsundere…?

I woke up today before the tsundere voice sounded.

I washed my face, changed into my uniform, and went downstairs.

“Good morning…”

I said this quietly while opening the living room door.

As expected, inside—

“…”

Everyone was silent, and a tense atmosphere hung in the air.

For some reason, Rinka didn’t go to morning practice today.

Ayuka had already finished breakfast, messing with her phone in a bad mood.

Fuzuha, like me, awkwardly moved her chopsticks.

As for Rinka, she sat in a chair with her arms crossed but hadn’t touched her food.

Was she waiting for me?

“Kiyoto, eat.”

Rinka noticed me approaching and urged me to eat.

“B-Before that, Rinka, what about morning practice today…?”

“…Are you really a senior?”

What did Rinka not going to morning practice have to do with me being a senior?

“It’s one week before the test starting today.”

“…Huh?”

Come on, you’re joking.

Rinka’s personality makes her bad at jokes.

Let me check… What!?

I checked the date on my phone, and it showed July 7th.

…It seemed I was the only one still thinking it was June.

“I-I’ll eat…”

I lost all energy and weakly put my hands together.

When I started eating, Rinka began her meal too.

“…”

Then Ayuka stood up so fast her chair almost fell, not looking at us, and headed to the entrance.

…This was pretty serious.

I should take care of Ayuka too.

Alright, your turn, Fuzuha!

“…Ha.”

Fuzuha noticed my signal and followed Ayuka.

“Wait, Ayuka-nee!”

Since they went to the same middle school, it made sense for them to go to school together.

“Hey, what are you looking at? Focus on eating with me.”

“Yes, yes… Wait, with you…?”

Did Rinka just say something super tsundere!?

She kept a straight face, but was she holding back a blush!?

“Hey, if you have time for stupid fantasies, eat faster.”

“…Sorry.”

Her tone didn’t sound embarrassed at all.

“Thanks for the meal.”

Breakfast was a bit smaller than usual.

Rinka probably felt guilty about yesterday.

“You’re done eating.”

“Yeah, this portion size is just right.”

Now that I finished eating, I’d head to Kirino-san’s house—

“Can we talk?”

Rinka’s voice stopped me as I tried to grab my bag from upstairs.

“Uh…”

“?”

It was rare for Rinka to hesitate with words.

“Since it’s test period and no morning practice… w-want to go to school together?”

“…”

Was this really Rinka in front of me?

The Rinka Nuregami who was once called a gender-swapped guy?

“You… want to go to school with me?”

“Isn’t it nice sometimes? Is that bad?”

Her gap-moe was killing me.

The usually cool and strict Rinka weakly asked to go to school together.

What guy wouldn’t fall for this?

Especially when it’s his little sister.

“O-Okay, let’s go together.”

“…Please.”

Rinka was already ready for school, with her bag in the living room.

I hurried upstairs to grab my bag and headed to the entrance.

“So you usually go straight to school like this.”

“I did until the day before yesterday… Oh!”

…I forgot something important.

If I went to school with Rinka, I’d run into Kirino-san.

From yesterday, it was clear those two didn’t get along.

But, well—

“What’s wrong, Kiyoto?”

Rinka seemed calmer today, so it probably wouldn’t turn out like yesterday.

So, I headed to Kirino-san’s house with Rinka.
