Hijiri is more understanding than I thought.
Come to think of it, you said before that you were bad at memorizing things... but if you look at the textbook like you are now, you might be able to use formulas to solve problems.
Of course, you won't be able to bring textbooks to the actual test, so you'll need to memorize them.
However, there are still nine days until the test, and I think I can memorize the main formulas if I keep solving them every day.
After all, the important thing about math problems is to solve a lot of them.
Even if you don't try to memorize it, the formulas will automatically be engraved in your brain during the process. Whether you like it or not, the formulas will keep going round and round in your head. That's just how mathematics is, so I'm sure Hijiri will remember it in the same way.
Thinking about this, I thought I could finally relax about mathematics.
"Phew, we did our best! Alright, let's take a break."
"Eh? Already?"
I've only got three questions answered so far.
However, Kiyoshi-san had a satisfied look on his face as he pretended to wipe the sweat from his forehead. The air conditioning was on so it wasn't the kind of temperature that would make you sweat, but... a cold head? No, looking closely, I couldn't see that she was sweating after all. Also, she looked unnecessarily pretty, so I couldn't really look at her directly and I stopped looking at her right away. Come to think of it, she was a beautiful girl. I had to be careful.
"Ah, I'm tired."
"...I guess it can't be helped if you're tired. Umm, that's right. I brought that with me to replenish my sugar."
Is it because you're not used to studying that you end up getting tired quickly?
It's still early days, but I'm ready to take a break. With that thought in mind, I took out some snacks from my bag. They were a bunch of individually wrapped, bite-sized chocolates. They're perfect for snacking in between studying, so I keep them on hand at this time of year.
"Hijiri-san, please."
"Oh, chocolate♪ Thank you!"
When I handed one to him, Kiyoshi accepted it with a big smile.
The moment he received it, he immediately put it in his mouth. As always, he eats it with great enthusiasm.
Hmm. I guess one isn't enough.
"...Feel free to eat whatever you like. I'll leave it here for you."
"Is that okay?!"
His expression, which had been gloomy from studying just a moment ago, is now bright.
He placed the bag next to Kiyoshi and began eating the chocolates one by one.
"Sweet♪ Chocolate tastes better when you're using your brain to study."
"...I don't think I've used my brain that much yet."
In contrast to her older sister's cheerful mood, Hime's expression remained gloomy.
Huh? I was hoping that she would be at least a little happy since my studies were going well, but... she seemed worried about something, as she was staring intently at my sister.
"I can't stop. I can't stop."
"...It's not a snack food."
Even though Hime points this out, Kiyoshi doesn't seem to care.
I gave him the chocolate with the intention that he would eat it in between studying, but before I knew it, eating had become his main focus.
"Hijiri-san? It's almost time for break to end and start studying..."
"Just a little more!"
...To be honest, I was underestimating Hijiri.
And I will come to realize.
What's really difficult for this person isn't his memory.
In fact, his mind isn't that quick. If you teach him the steps properly, he can even solve math problems.
After all, Hijiri-san has the same bloodline as Hime, so there's no way she's stupid.
However, there is a reason for the low grades.
It was because of her personality.
"...Night."
I was careless. When I looked away for a moment to check the scope of the math test, Kiyoshi had his eyes closed.
"What? You're asleep?!"
"...Hmm. It's like this every time."
Hime sighed in exasperation as she watched her sister take a nap.
"She doesn't have the motivation, and she just skips things. My sister is a sloth."
...Hijiri's laziness.
That seems to be the main reason why students fail.
