Reincarnated as My Little Sister

After club was over, I went home together with Yuna-chan partway.
The way home also has pedestrian traffic and bright, so it wasn’t that dangerous to that extent, but it seems like Nii-san is worried, so he told me to go home with someone if possible.
It is only midway home, but going home with Yuna-chan is fun, so there’s no problem.

“You see, Kohona-chan recently taught me how to skillfully serve♪”

“Aren’t your positions reversed there?”

“Since she’s the experienced one, it’s the not reversed you know. It’s normal right?”

It’s normal to ask the expert person to teach them you know.
Because I’m older, it can’t be helped that I was throwing my weight around you see.

“Well, it’s fine I guess; I’m going this way, so see you later…”

“Yeah, bye bye♪ See you tomorrow!”

“See you tomorrow.”

I continued to wave my hand until I couldn’t see Yuna-chan anymore, and returned home thinking it was somewhat childish.
It would’ve been better if I hadn’t done it.
While my face was slightly red, I noticed that Kouyou from far away when I turned to go home.

Kouyou always had the image of being together with Nii-san
Huh? But it seems like someone’s with him…?
…… A girl!?
Kouyou is together with a woman...

　◆◇◆◇◆◇

Kouyou is next to a girl. That never happened in my previous life, so I was shocked. I wonder what kind of relationship they’re in.
No way, a girlfriend!
I’m interested…… in the women’s face.
I only discovered this by chance, so her face was too far and I couldn’t see her face properly.
I can’t see it at all!

If I’d look a bit more closely, I’d probably be discovered, but I wonder if I should. Alright, let’s go.
I decided promptly.

As I approached, Kouyou’s familiar face gradually became clearer.
No, it’s not like I want to see Kouyou’s face or anything…
Alright! The women is also getting into view.

Hm? I’ve seen this person before...

...Natsuyuki-sensei!?

Why? Why in the world is Kouyou with my homeroom teacher…
Of course, if I don’t make contact, I won’t be able to talk with them though.

...I’m sort of curious what they’re talking about.
I need to get closer and make sure!

I approaching them with that thought, but their conversation seemed to have ended, and the two of them walked separate ways.
Only a bit more and I would’ve...

Or rather, Kouyou is walking over here!
I should be fine not hiding, but I looked for a place to conceal myself.
Fu, I felt like I some something bad for some reason.

“Naru-chan, what are you doing?”

I was exposed in an instant!?

“W-Well… what a coincidence. Good afternoon Morita-san.”

“Well, it looks like it’s becoming time for ‘good evening’.”

It’s getting dark soon.
Putting that aside, since we met, I should ask him about at first…
I am curious.

“Were you with someone at first?”

“Hm? Ahh, you saw. That was Natsuyuki-sensei. Naru-chan’s homeroom teacher.”

As expected, it was her.

“But why were you with sensei?”

“When I was in middle school, I received various favors from her. Since we met by chance, I was thanking her and chatting.”

I couldn’t imagine from the current teacher, but she was a nice teacher during my middle school days in my past life.
However, I did not think that Kouyou would give his gratitude.

“Hee, is that so?”

“Did you think she was my girlfriend? Were you jealous? Hey? Hey?”

“I did not. I was only curious.”

For a moment, I felt like Kouyou felt far away, but he immediately returned to his original idiotic face, so I was slightly relieved.

“I’m happy even if you were just curious~♪”

“Ahh, come on! Morita-san is truly like how is he is normally!!”

In the end, it was his usual noisiness.
