Tokyo Tutor: Starting with My Ex-Girlfriend's Sister

Chapter 20: Asking for Trouble

According to Yamazaki Kazufu's statistics, Himeno Saki Ryo went to the bathroom to pick flowers almost every twenty minutes during afternoon classes.

It seems that she has a biological clock inside her body that is comparable to an atomic clock. As soon as twenty minutes have passed, the drainage system immediately opens the floodgates to release water.

"Mr. Yamazaki, did I do that many things wrong?"

After grading the homework, Uesugi Aoi felt a little embarrassed when she saw the large number of mistakes.

"Uesugi-kun, you need to be careful even with your summer homework. Why did you get so many questions wrong, even in English, which is your best subject?"

"I'm sorry, Mr. Yamazaki..."

Sure enough, the high-intensity learning during summer vacation can easily make students feel tired of studying, leading to various problems.

For example, Himeno Saki's passive resistance to work, and Uesugi Aoi's inattentiveness.

Can I think of a way to increase their interest in learning?

Yamazaki Kazuka felt that this idea was somewhat anti-human.

From his own perspective, Yamazaki Kazuka still tried his best to explain all the questions to Uesugi Aoi.

"I'm done!"

After dawdling for a while, Himeno Saki finally finished and happily handed over the exam paper.

Yamazaki Kazukazu began grading papers, and the situation was much better than he had imagined.

"Saki-kun, let's start discussing the problem."

Yamazaki Kazuka breathed a sigh of relief; at least Himeno Saki could still understand the most basic content.

"Let me explain these questions to you again. After that, you can start doing your summer homework."

"OK."

Seeing that she had gotten so few questions wrong, Himeno Saki became very excited.

This is also one of Yamazaki Kazufu's methods. If Himeno Saki gets too many questions wrong, she will become very frustrated, lose confidence, and start to hate school again.

I simply gave her some simple problems to solidify her foundation before tackling more challenging ones.

This method is scientific, but is there enough time?

There's a saying that goes, "The best time to plant a tree was ten years ago, or it might be now."

Yamazaki Kazuka could only console himself with such inspirational words, and then gestured for Himeno Saki to lean over so he could explain the problem to her.

As usual, Himeno Saki Ryo lay face down on the table.

Why does it always happen like this?

Yamazaki Kazuka noticed that today's dress had an extra layer of black veil on the chest.

This makes its visual effect more appealing.

[Hehe, Yamazaki-sensei's eyes are starting to wander again.]

Uesugi Aoi was secretly delighted. For some reason, she always felt a sense of satisfaction watching Himeno Saki tease Yamazaki Kazuka in this way.

In particular, Yamazaki Kazukazu was struggling with his inner conflict while earnestly lecturing Himeno Saki.

[Mr. Yamazaki is secretly watching me again. Hehe, it's amazing that he can still give me a lesson like this.]

Even though accidentally exposing oneself is an embarrassing thing, Himeno Saki Ryo inexplicably felt a sense of accomplishment.

She had always been overshadowed by her older sister since childhood, and she felt inferior until she discovered her gaming talent.

Himeno Saki was so engrossed in the scene of her body being admired by Yamazaki Kazuka that she drifted off into thought again.

"Saki-kun, do you understand what I just said?"

Yamazaki Kazukaze once again noticed Himeno Saki's absent-mindedness.

"Mr. Yamazaki, what you just did...?"

Himeno Saki was stunned; she hadn't heard a thing Yamazaki Kazukaze had said.

Yamazaki Kazuka only glanced at it a few times out of the corner of his eye before lowering his head to begin his lesson.

After explaining a problem, I looked up and saw Himeno Saki's silly grin.

Anyone could tell that this guy was daydreaming again.

"I'm sorry, Yamazaki-sensei."

"I'll explain this problem again, but as punishment, you have to copy the answer and explanation ten times."

To teach Himeno Saki a lesson, Yamazaki Kazufu decided to increase the intensity.

"What, ten times? That's too many. How about five times, Mr. Yamazaki?"

"No, that won't work."

Yamazaki Kazukaze's attitude was very firm, and Himeno Saki Ryo, though very unhappy, had no choice but to accept it.

Seeing this, Uesugi Aoi was even happier.

"Uesugi-kun, please repeat the solution to the problem I just explained to you."

"Huh? Teacher?"

Uesugi Aoi stood frozen in place.

"If you can't repeat it, you can join Saki-san too."

Since there's no way to increase their enthusiasm for the time being, the only option is to use harsh measures to force them to listen attentively in class.

Afterwards, both of them slumped over the table with sorrowful expressions, copying texts as punishment. Yamazaki Kazuka began to think about how to motivate the two of them to study.

During this time, Himeno Saki Ryo glanced at Uesugi Aoi.

"What is it?"

"Uesugi Aoi said softly."

"You've forgotten. What did I ask of you this morning?"

Upon hearing this, Uesugi Aoi felt as if she had been struck by lightning.

"Are you sure you want to?"

"If you don't tell me about this, I'll tell my mom what you did."

Himeno Saki, who held Uesugi Aoi's weakness in his hand, revealed an evil smile.

"What are you two chatting about that's making you so happy?"

"No, nothing?"

The two quickly lowered their heads to copy the text. Although Yamazaki Kazuka was usually very easygoing, he was surprisingly strict in class.

Uesugi Aoi grew angrier the more she thought about it, and suddenly came up with a way to get revenge on Himeno Saki.

"Since my butt is going to get spanked anyway, Sakuri, you won't have it easy either."

"Focus on your homework."

Seeing the two girls whispering to each other, Yamazaki Kazuka couldn't help but speak up to remind them.

After a while, Himeno Saki, having finished copying the punishment, started doing her summer homework.

Halfway through, he encountered a problem and got stuck, so he had to ask Yamazaki Kazuka for help.

Seeing this, Uesugi Aoi realized that the time had come.

"Mr. Yamazaki, I need to go to the restroom."

This is Uesugi Aoi's first time today.

"Okay, go ahead."

"Saki, let's go together."

Uesugi Aoi stood up and patted Himeno Saki on the shoulder.

Then Himeno Saki looked up and stared at Uesugi Aoi with a look of utter disbelief.

"Are you crazy? This is my home!"

"Oh, I'm used to it at school."

Seeing that Himeno Saki's face was facing her, Uesugi Aoi, having achieved her goal, suddenly turned around and slammed her buttocks hard into Himeno Saki's face.

Caught completely off guard, Himeno Saki fell straight to the ground like a boxer hit by a powerful punch in the ring.

"Um. Aoi-kun, what's wrong with you?"

Yamazaki Kazuka was shocked by what he saw.

"Mr. Yamazaki, this is how we greet each other."

"In this way?"

Although high school students often do meaningless and childish things, Yamazaki Kazuka still can't understand such behavior.

"Uesugi Aoi!?"

Himeno Saki got up from the ground.

"Saki-kun, are you alright?"

"What are you doing?"

Himeno Saki growled these two sentences, his eyes blazing as he stared at Uesugi Aoi.

"Ahem, Aoi-san, you should apologize to Saki-san right away."

In order to prevent the situation from escalating further, Yamazaki Kazuka stepped in to resolve the conflict.
