Somehow I Ended up Dating the Perfect Female Classmate, but My Sister Found Out and They're Turning Into Yanderes - Chapter 40-41

Chapter 40: Fitness Date

“Here we are.”

“Ha… Rinka, your pace was a bit fast…”

The moment I saw our destination, I stopped talking.

A hardcore sports center!?

Who said anything about a love hotel!?

“Uh, is this really the place?”

“Where else would it be?”

Now that I think about it, the only place Rinka would go on a day off is somewhere like this.

But is this a place to come with your brother…?

“This is the biggest sports center in Joto City, right?”

“Joto Comprehensive Sports Center. It’s well-known nationwide.”

It looks as big as a large shopping mall.

I heard it even has a basement.

“So, what sports are we doing today…?”

“Well… we’ve already done enough running.”

More than enough.

We ran here from home, and it felt like five kilometers.

Rinka’s pace didn’t slow down at all.

She even stopped at a vending machine to buy me a drink.

Though her taste is terrible since it was vegetable juice.

“How about ping-pong first?”

Ping-pong?

It might suit me, but it’s probably the least suitable sport for Rinka.

“Come on, let’s go inside.”

The sports center is twice the size of a private high school gym.

It goes up three floors.

The first floor has basketball hoops and a volleyball court.

Some people are using them, but they don’t seem serious.

“Ping-pong is on the second floor.”

I follow Rinka upstairs.

The second floor has the same gym setup, but there are countless ping-pong tables.

And for some reason, it’s crowded.

Most people have serious looks.

Maybe the stereotype that ping-pong clubs attract people like me is true?

“That table’s free.”

Finding an open table is harder than expected.

Rinka picks a table right in the center.

Naturally, it draws attention.

The paddle and ball are on the table.

“Alright, I’ll go first.”

Shouldn’t you let me go first?

Whatever.

I’m new to ping-pong, but I’m good at ping-pong video games.

In that popular Olympic game, I crushed the max-strength NPC in ping-pong.

…Though I was too scared to play online because of toxic players.

So, I don’t think I’ll win, but I can hold my own against Rinka—

…

I couldn’t.

“Were you even trying?”

Rinka piles on as I completely lose my will to fight.

“I’m a beginner, so could you go a bit easier…?”

“What are you saying? I wasn’t even trying.”

There’s her catchphrase.

I noticed before the match, but why is everyone staring at us?

The guy practicing next to us was mesmerized when Rinka smashed the ball.

Either they’re stunned by Rinka’s coolness or excited by a guy getting crushed by a girl in a reverse-domination scenario.

“I wanted another round, but it’s clear you can’t match me in ping-pong. How pathetic. If we’re going to live together someday, how can you be this bad at sports?”

Sorry… wait, live together?

“I felt it during our morning run, but you lack stamina. You’ll need to keep up with me. No breaks.

Next, we’ll do one-on-one basketball.”

Wait!? Living together? Keeping up with her? (In a suggestive way?) There’s too much information, and my head’s spinning!

Is that why we came to the sports center?

If so…

Well, maybe I’ll give it a try… //

At that moment, my heart was completely stolen by Rinka.

Chapter 41: Declaration of Dependence

After that, Rinka and I played basketball, soccer, badminton, and tennis.

By the second half, I could barely move, but Rinka showed no sign of slowing down.

“You’re giving up already? That’s pathetic.”

“S-Sorry.”

Rinka looks at me with disappointment.

“Whatever. It’s getting pretty dark.”

I wasn’t paying attention to time, but we’d been playing sports for about ten hours.

Oh, Rinka said no breaks, but we did eat lunch.

It was just a convenience store bento, so I’m starving now.

“I sent Fuzuha a message earlier.”

“What kind?”

“To buy her own dinner.”

So…

“We’re eating out?”

“Y-Yeah, something like that.”

Why’s she acting a bit tsundere?

I can’t expect Rinka to escort me to a restaurant like this.

“W-Well, let’s go to a nearby family restaurant.”

“Y-Yeah. I wanted to eat out with you for once.”

We leave the sports center.

By the way, Rinka paid for everything.

The fee wasn’t too high, but since we stayed so long, it might’ve added up.

“So… where’s this family restaurant?”

“…I don’t actually know. I was about to look for one…”

“O-Okay. Then, as the one supporting you, I’ll take the lead and find it.”

S-Supporting me!?

Did she just say she’s supporting me!?

She mentioned living together earlier…

Does that mean my future job is being a gigolo!?

My lifelong dream came true.

“Hey, that place looks good.”

While I’m lost in weird fantasies, Rinka already found a family restaurant.

“…It looks a bit expensive.”

“Don’t worry about the cost. I’ll make sure you lack nothing.”

Our conversation feels off, but if Rinka says so, I can’t argue.

We enter the family restaurant.

It’s surprisingly crowded, but there are still seats, and we’re told to sit anywhere.

“We’re just two people, so should we sit at the counter?”

“Meals are usually eaten face-to-face. Eating while looking different ways defeats the point of coming together.”

“S-Sorry.”

She gave me a serious reply.

We end up sitting at a regular table.

“Alright, I’ve decided. Hurry up and choose.”

So fast!?

Did she plan to come here and already check the menu?

“I’ll have the katsu bowl.”

I press the button to call the waiter.

Rinka reads off my order too.

“One katsu bowl and one large seafood bowl.”

A large seafood bowl???

It might be rude to say this about a girl, but… that’s a lot of food.

I thought Rinka would order something like a sirloin steak.

“…”

“…”

And here’s that silence again.

“Sorry about today.”

“Huh?”

“For dragging you to the sports center without telling you.”

That’s very Rinka, and I’m not mad.

But her apologizing makes me realize she’s changed.

“…Hey, Kiyoto.”

“W-What?”

“…I’m competing in the Kanto kendo tournament this summer.”

“Oh, yeah.”

I’m not surprised.

With Rinka’s skill, it makes sense she’d compete in the Kanto tournament.

“Will you… come cheer for me?”

“Cheer?”

“I know you’re a senior with exams. But still, will you come…?”

“…Of course I’ll go.”

“!? R-Really!?”

“I want to cheer for my little sister’s big moment.”

Since I’m aiming for a recommendation, summer cram school is just an excuse to see Kirino-san.

“W-Well, yeah. As family, or even more, it’s only natural you’d cheer for me.”

…The last part sounded concerning, but I’ll pretend I didn’t hear it.
