This is the first time I've gone shopping with my sister since crossing over with a horse.

Chiyoko carried the bag in front of her and protected it very preciously - after all, it contained "a huge sum of money".

Kazuma thought to himself that you were pressing the bag so preciously, which was not the same as saying to the thief, "Come on, there are good things here", but when he saw Chiyoko smiling so happily, he cheered up himself and paid attention to the surroundings, so that Chiyoko could continue to jump as she wanted.

After all, the past April has not had any happy memories for Chiyoko.

There were many pedestrians on the street, and Kazuma thought that he would see a lot of office workers who went to the izakaya to participate in "social events" after work, but it turned out that this was not the case, and most of the people on the street were families who dragged their families and led the group to act, and there were many children.

However, when he thought about it, even in a place like Japan in 1980, where workaholics were everywhere, there were still many people who chose to come out on the first day of Golden Week to enjoy family fun.

Chiyoko took Kazuma's hand and headed straight for the newly opened large shopping plaza in front of the station.

Kazuma looked at the gorgeous interior decoration of the shopping mall, and said a little worriedly: "The bookstore in this is very expensive, right?" ”

"Brother, books are all priced at a unified price, and the price will not change wherever the bookstore opens."

Chiyoko said as she pulled Kazuma into the gate of the shopping mall.

"It's so cool!" Chiyoko sighed, "It's getting hotter and hotter, it's time to take out the fan at home." ”

Of course, there were already air conditioners in this era, but the Kiryu family certainly couldn't afford it.

Not to mention buying an air conditioner, the monthly electricity bill after buying an air conditioner is enough.

You can only use electric fans and ice water to cope with the hot summer days.

When it comes to electric fans, Kazuma suddenly remembered one thing: the whole wind chime has to be hung on the edge side, how can there be no wind chimes in summer?

In line with the season, you have to do everything that you have to do, and you may be able to pick up the state in vain.

Kazuma was thinking about it when he suddenly noticed Chiyoko's gaze drifting towards clothes and cosmetics.

He Ma smiled: "Go to the fashion counter to see?" ”

"Don't go!" Chiyoko immediately rejected Kazuma's proposal and dragged Kazuma to the bookstore.

A few minutes later, Kazuma stood in front of the bookstore's textbook shelves, his brows furrowed.

Although he had heard that professional books and teaching aids in Japan were expensive, he didn't expect them to be so expensive - maybe this time and space was not the same as the previous life, and the price of books was printed by an extra zero?

He Ma casually pulled out a textbook to prepare for Meiji University, and looked at the price—Nima's poor children may not even be able to afford it.

However, it seems unlikely that the people who would choose to go to a private university would have been children of poor families.

Kazuma carefully put the book back on the shelf.

He felt the gaze of the clerk behind him, and considering the price of the books on this bookcase, it was normal for the clerks to be so nervous.

Chiyoko took out the list that he had just put in her bag with Ma, and said while looking at it, "Brother, which subjects are you not good at, let's buy books on those subjects first." It's more expensive than I expected, maybe just enough to buy a few copies......"

Hema replied without thinking: "My country is not good at literature, and there is history." ”

"Huh?" Chiyoko was shocked, "I can use a difficult four-character idiom accurately, but the Chinese language can't be used?" ”

Being able to use a four-character idiom is the knowledge that I brought over from my previous life.

And Ma muttered in his heart.

"I'll see, the national language and history should be here......"

"Kiryu-san?"

Turning back with Ma and Chiyoko: "Huh? ”

After all, both of them are "Kiryu-san".

The girl with thick-rimmed glasses and thick braids was startled by this uniform movement, took a small step back, and then she reacted.

"Ah, this is your sister Chiyoko Kiryu, right?"

Chiyoko stared at Kazuma's side face suspiciously: "Brother, who is this?" ”

He Ma scratched his head: "It's the chairman of our class." ”

Calling the chairman is really not used to it, and I always feel that she will manipulate something at any time.

The chairman pushed his glasses: "You even call me by your job name, Kiryu...... It's really too much with Ma. ”

The chairman was going to continue to call Kiryu-san, but in order to distinguish whether it was an older brother or a younger sister, he changed it to Kazuma-san.

In Japan, it is a sign of intimacy to call one, regardless of whether it is added or not.

Chiyoko raised her eyebrows, her gaze sweeping the chairperson from top to bottom like a scanner.

Then she patted Hema's waist hard: "Brother, you're very good." ”

Hema ignored his sister and said directly to the chairman: "What a coincidence, chairman, you also came to buy teaching aids?" ”

"Well, the teachers gave you a list of books, and I asked the head teacher to get a copy of it as it was." As he spoke, the chairman showed the book list in his hand to Kazuma, but compared to the one in Kazuma's hand, the chairman's book list was full of notes.

He Ma took the book list, looked at the notes on it, and found that it was written about the ways to obtain various books.

Some of the books are marked as "library collections", some are written "used bookstores may have", and some are crossed out directly, and it seems that they have been ensured.

Kazuma: "Awesome, chairman, worthy of ......"

He Ma almost said "worthy of being a master of micro-exercises", but changed it to "worthy of being the chairman of the committee" halfway.

The girl pushed her glasses: "Why does it sound like you're teasing me?" ”

"No, your delusion."

The chairman shrugged his shoulders, and then took back the book list: "Teaching aids are so expensive, it costs a lot of money to buy all new ones, so it's better to find some cheap means to start." After all, you have to pay extra money to go to cram school or something, and it shouldn't be enough to rely on the school teacher's small stove. ”

"Yes...... That's right. He Ma can only echo, "You really think about it very carefully." ”

"Didn't you think about it?" The chairman asked rhetorically.

And Ma responded seriously: "Now it's being considered." ”

"Huh? I thought you had been in cram school since winter break. So what's going on with your sudden improvement in English and math? ”

Kazuma's back began to sweat, and she always felt that if she continued to ask, it would be time for Yuan to come back.

"Well, I taught myself." And horses, hard braces.

The chairman continued to ask: "Self-study? What kind of teaching aids are used? I also want to try such a good teaching aid. ”

"Uh, with a textbook." Kazuma felt that he couldn't hold it anymore, especially in the face of the other party's intelligent gaze from behind the thick-rimmed glasses, which made Kazuma feel like his little secret was about to be completely exposed.

The chairman stood in place and pushed his glasses: "Textbooks? ”

"Yes, be proficient in the content of the textbook, lay a good foundation, and then you can be at a high level."

"Is there calculus in the textbook?" The chairman asked suspiciously.
