I’m Having Trouble With a High School Girl I Meet on the Commuter Train Who for Some Reason Has Take

My sister Aina came with Yuika.

So far, so good.

The problem started when Aina said she was going to get us together.

I brushed my bangs and said in an exasperated tone, “Why are you trying to get me and Yuika together?”

“You do know the person who will be your wife is going to be my sister, right? In that case, I also have the right to choose.”

“No, you don’t.”

I’ve been alive for twenty-six years, and I’ve never heard anyone say such a thing.

As I was exhausted and aghast, Aina held up her hand in a pose of an anime character.

“Aina Sasamiya Orders you. Confess your love” 

(T/N: Ahh Is this Geass? Lelouch’s pose when he orders?)

“Hey, don’t give me orders.”

Aina’s selfishness was nothing new, but this time it couldn’t be helped.

""

In the first place, there was no way Yuika would want to go out with me.

From her point of view, I was an old man.

Just being asked to talk about this kind of thing was going to set off her usual harsh tone.

…… Gughh

I heard the door open and turned around to see Yuika peeking through the gap.

“Hey. I changed my clothes… but what should I do?”

“Wa~! Show me, show me!”

Urged by Aina, Yuika timidly revealed her cosplay.

It was the magical girl cosplay that was so popular in the anime.

She wore a short skirt and a corset that emphasized her breasts.

As expected, she kept her hair as it was, but wore a beret instead, the same as the character’s.

It was a costume that suited her perfectly.

Seeing it live was completely different.

No wonder so many people look forward to cosplay.

“Hehh~, isn’t it cute? It suits you, Yuika”

When I said what I honestly thought, Yuika covered her lips with her hand.

“Amazing. For the first time, Onii-san is able to use witty words… I can’t help but be surprised.”

“Why am I being made fun of for giving a proper compliment?”

My sister Aina, on the other hand, made a gesture as if she was crying.

“Ugh~, bro~! When did you grow up?~ I’m so happy~”

“I don’t think there’s anything to cry about, you know?”

Yuika always teased me, but I didn’t expect even Aina to react the same way. ……

I guess they must have been exchanging stories beforehand?

Aina approached Yuika and clasped her hands together in a begging pose.

“Hey, Yuika-san. Let me take a picture of you and my brother together. Please~”

“Yeah, sure. Aina-chan you might as well cosplay and let’s take a picture of the three of us together.”

“Are you sure!? I did it! Then, I’ll change right away!”

Perhaps she was so happy to be asked to take a photo together, she immediately packed her things and went into the next room.

Just in time.

I’ll use this opportunity to talk to Yuika.

“Hey, Yuika. Isn’t it bothersome to take a picture with me?”

“It’s fine. I’m the type of person who doesn’t care if I’m in a picture with a kappa or anything.”

“Huh? Am I being treated as a youkai?”

“More like a rare beast.”

Yuika, who made a light joke, beckoned me…to come closer to her.

Then she brought her lips close to my ear and started whispering.

“Aina-chan is trying to get me and Onii-San together, right?”

“……, did you hear that?”

“If it’s that loud, you can’t soundproof it with just one door.”

If she knows, then so be it.

In the first place, Aina’s plan won’t work in front of Yuika.

I bowed my head in resignation.　　　

“I’m sorry. That girl…. She goes out of control as soon as she’s interested.”

But Yuika shook her head.

“For now, let’s just go along with Aina-chan. I’m sure she’ll be happier that way.”

That was unexpected.

No matter how close they were, I didn’t understand why Yuika thought so much about Aina.

“Yuika, why do you care so much about Aina?”

“Hmm. It’s best to get along well, but if someone is doing their best, you’ll want to cheer them on, right?”

I see.

Yuika recognized Aina not as a younger person, but as a proper adult.

That’s why Aina was so attached to Yuika.

At that time, the door of the next room opened with a bang.

“Ta-da! Look! My brother had a gothic lolita maid outfit! It even has fox ears and a tail!!”

Aina exclaimed cheerfully, wearing the maid outfit I had prepared for Comiket.

The smallest size was not used, so it was stored in the closet until I returned it.

Seeing this, Yuika murmured in her usual tone.

“That outfit was In Onii-san’s personal belongings.”

…Hmm? What, Am I being misunderstood here?

“… No,… no. That’s work equipment…”

""

“Yes, yes, For sure. It’s okay. I understand.”

“Please, put some emotion in your voice.”
