After the teaching session for Katase Seri, Rintaro arranged the exercises prepared for her last night, and Rintaro also adopted the same method for Katase Hatsuki. However, the speed of solving the problem is much faster than that of his sister, Katase Hatsuki, who quickly completed his part. Rintaro happened to use this time to check Katase Hatsuki's completion status.

Then I found something that was the same as what Akiyama said. No matter how difficult the question is, Katase Hazuki always seems to make some mistakes in some details. Sometimes it will not affect the general result, but if you answer the question in this situation, you will indeed lose a lot of points in vain.

Rintaro thought about his language, then swallowed it back, and then said to Katase Hatsuki: "Student Yeyue, you can do the question I just gave you again, this time it can slow down a little."

Katase Yeyue raised his eyebrows and looked at Rintaro, and then did as he did. However, Rintaro did not feel that Katase Yeyue's speed had slowed down. So, after the same time, Katase Seri completed about two-thirds of his homework, and Katase Yeyue completed his homework again.

Rintaro checked her again. After reading it, he felt something-?

If Rintaro had ten mistakes when checking Katase Hazuki's homework for the first time, then the second homework still had ten mistakes. If it was the usual situation, Rintaro would think that this was Katase Hazuki's normal level, after all, the number of errors has not changed.

But you changed the wrong place again, it doesn't seem good, right?

"Well... Ye Yue's classmate." Rintaro pondered for two seconds, then met Katase's cold gaze: "...It's done well, at least I already know very well that you have the ability to do all these two questions correctly, it's pretty good."

Katase Hatsuki still looked at Rintaro, but Rintaro seemed to be able to read something from her eyes.

Isn't this taken for granted?

Probably that's how it feels.

but……

"Let's do it again. This time we will be more serious, more careful, and a little slower."

Katase Yeyue looked at Rintaro with doubts, but after looking at Rintaro's zombie face, Katase Yeyue nodded. Then he did it again. This time, he happened to complete his part of his homework with Katase Seri. Rintaro got Katase Seri's answer and said to Katase Hatsuki: "You check it first, check it carefully, and I'll take a look at Hoshiri's classmate."

Katase Hatsuki's eyes were full of doubts. She looked at her answer seriously, and then successfully found two mistakes and corrected them. Rintaro looked at her distractedly, feeling very relieved.

There was no big problem with Katase Seki. Rintaro also gave Katase Seki a little explanation. After Katase Seki understood it, she did the question again. It was such a worry-free child. Given Katase Hazuki enough time, Rintaro then looked at the answer she gave again.

This is the third time I checked Katase Hazuki's answer, and I also watched her correct two places. This time, the previous situation should not happen again, right?

Rintaro looked at the answer from Kasase Hazuki and his blood pressure suddenly became high.

He looked horizontally and vertically with the paper full of answers, and saw two idiots between the lines - idiots. He felt that Katase Yeyue was mocking him, so he put down the answer paper, looked at Katase Yeyue, and said something he said a long time ago: "Did you mean it?"

The words Rintaro said with an expressionless zombie face seemed to be subconsciously shrank his neck because of someone's reaction engraved in DNA, and then looked at Rintaro. Her sister looked at Rintaro with the same cold face, silently expressing her doubts.

"Student Ye Yue... I always thought you would be a very smart, well-behaved and worry-free child..." Rintaro said earnestly.

"Then you may have read me wrong." Katase Yezuki interrupted Rintaro's spell cast very cleverly, causing Rintaro to glare at her expressionlessly.

"The question I just gave you, you made ten mistakes the first time, and the second time all these mistakes were corrected. This is very good." Rintaro began to comment on Katase Hatsuki. Katase Seri looked at his sister with admiration, but Katase Hatsuki felt that this was not that simple.

"But... Ye Yue, tell me why you can correct the previous ten mistakes while also making the questions wrong in other places that have already been done correctly? And there are still ten places where the mistakes are wrong?"

"...A momentary negligence." Katase Yezuki explained in a low voice.

"It's okay to say these two times. After all, small mistakes are possible. But how could you make ten mistakes accurately on the third time? Especially two of them were corrected after I reminded you. Don't say that I wronged you, I have a legitimate reason to suspect that you are mocking me."

Katase Yezuki seemed to be embarrassed and turned her head in another direction.

"Is it possible, Ye Yue, are you actually the kind of person who has the type of protagonist who can control your scores in normal times, suddenly exerts your true strength at the right time, and then wins the top score in the whole school in one fell swoop?"

"Please don't add strange settings to others casually." Katase Yezuki retorted: "It's just... a momentary negligence."

Katase Hazuki does not admit that she has that setting.

But Rintaro's eyes became more and more complicated when he looked at her.

In my mind, a script like "Although my grades are pretty good, I still need to retain my strength, make a splash at the most important moment and successfully achieve my goals, and through this foundation as a starting point, I can achieve an extraordinary life and shatter my mother's oppression on my sisters." It was released in Rintaro's mind.

"Although I don't know what you are thinking, I always feel like you are thinking about something unrealistic." Katase's words brought Rintaro back to reality.

"Then you can explain why you can get ten mistakes in three consecutive times on the exact same test questions, but you can do everything right. You know, Ye Yue, this is probably not reasonable." Rintaro held his hand.

"It's just a momentary negligence..." Katase Yezuki insisted on her statement.
