After eating breakfast and getting ready to go out, Hana and I went to the center of the city by train—and as I don’t especially have anything I needed, today I would just go wherever Hana wants to go.

“Nee Onii-chan, which do you think is better, this one or this one?”

Hana asked my opinion as she adhered two one piece dresses on her body. One is a black dress while the other one is a light blue dress.

Both have a contrasting impression, but as expected in this case—

“Let’s see. I think the black one that looks like it’s swallowed by the darkness is better.”

“Then, I choose this one.”

Having said that, Hana gave the black one piece dress back to the clerk and purchased the light blue dress.

Oi, why did you even ask?

Anyway, right after we left the store, Hana pointed her finger to a certain direction.

“Look Onii-chan, it’s a crepe shop. Let’s go there!”

“Alright, alright.”

We lined up at the crepe shop with my hand being pulled by Hana. Then, Hana’s eyes shined as she looked at the menu placed at the store.

“I choose this strawberry crepe. What about you, Onii-chan?”

“Let’s see…Banana chocolate, then.”

Hana’s eyes widened when she heard my answer.

“Are? It’s unusual for Onii-chan to buy this kind of thing. Usually, whenever I asked what you wanted to buy, you always rejected it with ‘I’m fine’. What happened all of a sudden?”

“Muu…”

Certainly, I have always avoided these kinds of extra expenses and only bought things for Hana at such times. However, I have some money that I earned from capturing the dungeons right now. So, I think a bit of luxury could be allowed this time…

Still, because it would be troublesome to explain such circumstances, I tried to think of an excuse.

“I have had a sweet tooth since yesterday.”

“Since yesterday!? W-what happened for you to become like that..”

Yosh, looks like I have successfully deceived Hana with that. I think this is what is called ‘Perfect Communication’.

After that, Hana and I, who have just received our crepes, went to sit on a nearby bench.

“Itadakimasu. Nn, It’s so sweet and delicious!”

“Yes, it’s delicious”

The crepe was very delicious with how sweet it is. I guess this kind of thing is good once in a while.

“Onii-chan, let me take a bite of your crepe too”

“Nn? Okay…”

When I was about to hand the crepe with the paper that wrapped it, Hana widely opened her mouth and bit the crepe just like that. While I was surprised by Hana’s aggressive behavior, something happened.

“Eh..? Rin-san, Hana-chan? Why are both of you together…”

A voice that I have heard before shook my eardrum. When I looked at the direction of the voice, Kasai Yui, the girl that I just met yesterday stood there.

“Yui?”

“Yui-Senpai?”

Hana’s voice and mine overlapped. Apparently, Hana also knew this girl.

“Hana, you and Yui know each other?”

“Y-yes, she is my senpai in high school. Rather, I was more surprised that you two know each other, what kind of relationship did you two have?”

“She is my acquaintance adventurer. I met her in the dungeon the other day…Nn? What happened, Yui?”

Yui was looking at us absentmindedly. She regained her usual state when she heard my question.

“I-I’m sorry to suddenly call out when both of you are together. I didn’t know you two have that kind of relationship….”

“That kind of relationship?”

Are you talking about Hana and I being brother and sister? Well, it can’t be helped that she didn’t know about it since I had not explained it before. That’s what I thought, but…

“I never know you two are such a lovey-dovey couple…”

“”Couple!?””

Looks like Yui has a great misunderstanding.

“Wait a minute, Hana and I were not a couple. And didn’t you say yesterday that you have an acquaintance with Amane as her name? You were talking about Hana, right? If I said this far, you understand what I mean, right?”

“I-I see. In other words—“

I stroked my chest in relief because it seems she finally understand that Hana and I are brother and sister—

“—It means student marriage, right!”

“Not even close!”

How did she even think to get this conclusion? I sighed deeply and next to me, Hana smiled bitterly.

“Ahaha…As always, what an extreme imagination.”

“She has been like this for a long time, huh…”

Then, we tried to explain to Yui about our relationship while still in exasperation. It was five minutes later when Yui understood that we are brother and sister.
