I returned home from the pool in the evening. Even though I had taken a shower there, I still felt uncomfortable, so I decided to take a bath before dinner.

“Mina, I’m out of the bath!”

“Yes, yes. Make sure you dry your hair properly with the hair dryer there.”

“Will do!”

An appetizing aroma was drifting through the living room. This must be… curry.

“Curry in summer… it’s the best!!”

“By the way, it’s summer vegetable curry with plenty of vegetables.”

“Excellent!! You know, everything you make is delicious, so your brother is really happy. Your future husband is going to be one lucky guy~”

After all, she was such a beautiful girl, a tsundere who easily showed her sweet side, and she was excellent at cooking and all household chores. I heard she was popular at school too. When Mina brings home a boyfriend, I’d have to conduct a strict examination…

Suddenly, Mina’s hand stopped stirring the curry. Was it ready?

“Hey, big brother… what do you think of me?”

“What do I think? Well, you’re my tsundere, domestic, very cute sister that I’m proud of, of course.”

Why was she asking such an obvious thing now?

“Th-thank you… for praising me like that. Then… when we went on that double date at the amusement park before… how was it?”

“How was it…? It was fun, wasn’t it?”

“That’s not what I mean! …You know, we were pretending to be boyfriend and girlfriend… what did you think about that…”

“What did I think…”

“I-I can say it…! Don’t underestimate me! …I’ve been practicing in secret all this time… Then I’ll say it, okay? Um… Sh-Shotaro…kun?”

…She was just so cute.

“It was really good. I was happy to be the boyfriend of a cute girl like you, Mina. Even if it was just pretend.”

I spoke honestly. I might have weirded her out by saying such things to my own sister, though.

A moment of silence.

Wait, hold on. I was sad when there was no reaction, but…

“…I see. D-don’t read too much into it! I’m going to take a quick bath now, so keep an eye on the curry!”

“H-hey!”

She left as if she was running away.

What was that about? Well, my sister was cute today too.

Chapter 28: The One Who Waits

A week had passed since summer vacation began. There should still be about a month of break left. Yet there I was, wearing my uniform, at school.

“Do you guys understand why you were called here a week into summer vacation?” asked the PE teacher, Kato-sensei, dressed in his tracksuit.

The blazing sunlight. Cumulus clouds freely swimming across the blue sky. The sound of cicadas and the loud cheers of the baseball team could be heard from outside.

In the classroom without air conditioning, the only lifeline was the breeze coming through the open windows.

The sweat making my uniform stick to my skin was unbearably uncomfortable.

Summer… It was summer. Summer vacation. Yet for some reason, there were scattered students in the classroom.

Kato-sensei sighed in the quiet classroom.

“…Haah, somebody answer… Mitarai, you know why you were called here, right?”

“Because I had too many failing grades on the recent tests, sir.”

“That’s right. You all failed your tests. You understand? At our high school, if you fail even one subject, you get summer remedial classes… Well, some idiots failed four subjects.”

That would be me, yes… But I’m just not good at studying!!!!

“Unfortunately, your summer will be consumed by remedial classes for a week starting today. Well, you should be grateful we didn’t start remedial classes on the first day of summer vacation.”

A week into summer vacation was when your body got used to resting, your sense of time gradually became numb, and you started thinking that you should begin your homework soon while being awake during the day. To have remedial classes at such a time… Damn it!!

After three solid hours of studying…

“That’s it for today’s remedial class! Don’t you dare fail next year. Otherwise, your precious summer will disappear again~. See you tomorrow~”

I’d never felt such hatred for the words “see you tomorrow”.

I hurriedly left the classroom in search of cold ice cream. If I had to suffer this much, I should have asked Mina to teach me, even though she was a third-year middle school student preparing for entrance exams. Mina was smart and always maintained a position within the top five in her grade, so there was no need to worry about her.

As I exited the school gate, there was a familiar figure.

“Huh, Mina?”

“Ah, finally done? You’re late.”

“S-sorry… Wait, you were waiting in this scorching heat? Mina’s fair skin will get sunburned!”

“I-I’m wearing sunscreen so I’m fine. Don’t touch me all sticky like that! A-and I wasn’t waiting the whole time! I was j-just passing by the school…”

Mina turned her face away as if embarrassed. I didn’t miss the sweat on her neckline.

“I was thinking of buying ice cream on the way home… my treat?”

“Thanks. Häagen-Dazs, of course.”

“Leave it to me.”

We started walking together. These relaxed everyday moments as siblings were really nice…
