When I woke up, it was already late in the evening.

Although I kept saying that I was fine, when my head touched the pillow, I immediately lost consciousness.

Recently, if you want to say that there is no problem, it is definitely self-deception.

"Light, are you awake?"

It's a bit surprising that I'm surrounded by a senior sister who has always taken care of herself.

"Senior Sister Bi, have you stayed until now?"

"yes, yes."

As if he was saying something for granted, he replied very naturally.

It's still the same, this gentle senior sister always takes things that trouble her for granted. Honestly, I was a little impressed. She's so popular at school definitely not just because of her flattering appearance.

I looked left and right, but I didn't seem to see the dome in sight.

"Ah, Sister Dome said, because the doctor said you should wake up around the evening, so she seems to be going to make you some dinner, so she must be busy right now."

"How do you ......"

"Ah, guessed right?" Yan Bi clasped her palms together and laughed. "Your brother and sister have a really good relationship."

Mitsuki Umihara changed the subject with some embarrassment.

"You care too much, I said it wasn't a big deal......"

"No, it's not." Ji Yanbi interrupted him, "The doctor came while you were asleep, and we couldn't wake you up at that time, but Sister Dome was frightened. ”

"Is it that serious?"

"Look, it's a doctor's diagnosis."

He received the diagnosis from the hand of Ji Yanbi, and the conclusion of "unexplained brain wave abnormality" was clearly written on it.

If you want to talk about the cause of brain wave abnormalities, it is not too rare, and the first thing that comes to mind should be concussion or something. But I don't remember anything that happened that caused the brain wave abnormality.

"In short, the doctor's recommendation is to recuperate for two days. You can't be the kind of person who can't calm down, right? ”

"Don't make fun of me, Senpai. Anyway, isn't there a problem with you not going to school today? ”

"It's okay, the president helped me ask for leave, and the teacher has agreed. It's Sister Dome, nothing, right? ”

"No, it doesn't matter. She didn't go to school for a while, so there was no such problem. ”

"Didn't go to school?"

"There was someone like a governess to teach her. And if she went to a normal school, it would be a waste of time. ”

"Huh? Is it a waste of time? ”

Ji Yanbi didn't understand what Mitsuki Kaihara meant. Kaihara smiled, reached out and took a notebook from his bedside and handed it to hers.

I opened it for some reason and looked at it, and there were a large number of calculations recorded in Juanxiu's font in the notebook, which made it completely incomprehensible.

"What is this?"

Ji Yanbi was confused.

"It's her study notes, which I recently asked her to borrow, and this one is about non-relativistic quantum field theory. Ordinary schools can't teach this, right? ”

Truly......

Although I have heard Haiyuan inadvertently mention his sister's excellence many times, is this girl so good?

When mentioning his sister, Haiyuan always has a proud look, which can be understood by seeing Qiong Nai Yanbi.

Amazing beauty, brilliant mind, clear voice, flawless character. Seriously, even if it's just a brief contact, this girl is very fond of Yanbi. It can even be said that there are people who don't like her, and it is a question of whether they exist.

But......

"Humph......"

Ji Yanbi deliberately leaked something as if "I'm going to be angry!" sounds.

"What's wrong?"

"Hikari, are you natural?"

Obviously, Mitsuki Umihara didn't understand what she meant for a while.

"What do you mean by that?"

"Boasting about another girl in front of a girl, how brainless it must be to do such a thing."

"Ah, so that's what you mean, senior sister. I'm not worried. ”

"Huh?"

As a result, it was Yan Bi who was surprised.

"Because of Senior Sister Bi, the so-called comparison, from a certain standpoint, is also some kind of special war. Generally speaking, smart people don't take the initiative to provoke a war that is sure to be lost, right? ”

was completely seen through.

In fact, although not as good as a mortal, Dome is the type that is definitely not annoying. On the one hand, it's because of her own good character. On the other hand, as Mitsuki Umihara said, no one will compare her with himself.

A meaningless and inevitable war that no one in their right mind will fight, right?

Most of the so-called jealousy has a premise of comparison. If even the premise is not satisfied, it is often difficult to establish.

"Of all the things you've ever said, this one hurts the most."

Yan Bi pretended to be indignant.

"Perhaps, but only what has been said. If you don't say anything in order to lie to you, that's even more hurtful. ”

Yes, this junior of mine is such a person. It's hard to figure out whether he's too stupid or too smart.

"Well, whatever you want."

But then again, that's why he's always very pleasing in every way.

Just like his sister, the person who really hates him should not exist. Although the types are different, they can always attract others unconsciously, and they can only be said to be brothers and sisters.

"Speaking of which, I haven't thanked you yet. Sister Bi, thank you very much. ”

"No, I don't. Actually, I didn't do anything today, it's Sister Qiong Nai who has been taking care of you, and I can't intervene at all. ”

"Is that so?" Haiyuan's face gradually became a little gloomy, "This stupid guy is obviously preparing for the exam, and he is still wasting time on this kind of thing......"

"Exams?"

"Ah, it's Tokiwadai's entrance exam. After all, it's better to go to school normally in middle school. ”

Tokiwadai Junior High School is probably the most famous junior high school for girls in the world. As you can imagine, the entrance exam will not be easy.

"I see. But I think even if you ask her to hurry, she won't be able to learn. Ji Yanbi clapped her hands lightly and said with a smile, "Look, your brother and sister have such a good relationship, you are the way you are as an elder brother, it is absolutely impossible for Sister Qiong Nai to study with peace of mind, right?" ”

That's true, although Mitsuki Kaihara himself doesn't quite want to admit it.

"Senior Sister Bi, your words are also very hurtful, how did you do it, I seem to be a burden."

"If you don't want to be a burden to your sister, just recuperate and get better as soon as possible."

At this time, Dome walked in with a prepared dinner. When she saw Haihara who had woken up, she could simply describe her joy. For her, who always gives people a relatively indifferent feeling, this is actually not common. Of course, this point, Ji Yanbi, who met Dome just now, didn't understand. However, there are similar feelings.

Yan Bi stepped back a little. It's not for any reason, it's just that she thinks that the most ideal brother and sister in the world should be like the brother and sister in front of her, and there is a feeling that outsiders can't intervene at all.

Although it seems that most of the siblings are not very good with each other, and even the better relationship will behave more ordinary, but these two people are obviously not like this.

Close but not sticky, respectful and caring enough for each other. An almost perfect brother and sister duo, an almost perfect brother and sister relationship.

Honestly, envious. But I also understand that it is something that I will never be able to achieve.

Concepts such as "family......

So, Ji Yanbi chose an appropriate time to get up and say goodbye.

Since it was almost dinner time, the Haiyuan siblings wanted to at least stay for dinner, but she insisted on leaving. Although this senior sister is gentle, no one can change what she insists on. Mitsuki Haihara understood this, so he didn't force him to stay.

Although he said that he wanted to rest, Kaihara did not plan to do nothing. He picked up the textbook he had borrowed from his sister and flipped through it.

Seriously, it's tough. Haiyuan's physics and math are very good, but he still has a headache from this thing during this time. In any of these passages, Haiyuan had to struggle to understand some of them. Tokiwadai actually used this kind of thing as the content of the entrance exam, I really don't know what the reason is.

About two hours later, someone walked into Kaihara's room.

Kaihara put down his book and saw his father sitting at the head of the bed.

"Didn't you sleep?"

"I've slept enough today."

My father sometimes came back late, and that seems to be the case today.

"I've heard Dome say it, how are you feeling now?"

"It's fine."

"Is it an accident that you will get sick, has the cause been found?"

Regarding his father's doubts, Haiyuan himself also felt the same way. I have always been quite healthy when I participate in reasonable physical exercise, and at most I only get some common colds.

"No, the doctor couldn't tell what it was. However, it doesn't seem to be too much of a problem. ”

"That's good." Father's eyes fell on the textbook in Haiyuan's hand. "Since it's a break, don't look at this kind of thing."

His father was a theoretical physics student, so he could understand what it was just by looking at it, and he took the book directly from Kaihara's hand.

"It's just a little boring to do nothing."

Mitsuki Haihara replied casually. But his father seemed to be stunned suddenly, and he looked through the textbooks he had taken from Kaihara's hand, and his face gradually turned pale.

After going through the textbook as quickly as possible, my father quickly got up and took away all the things related to Haiyuan's bedside, including notes, without leaving any room for negotiation.

"Tell me where you got this textbook? I don't think a regular bookstore can buy it. ”

My father, who has always felt more like a scholar, lowered his tone, and it actually gave people an amazing sense of oppression.

"This—This seems to be the entrance examination textbook used by the dome ......"

"Bastard! What kidding!"

His father is not a person who gets angry easily, but on the other hand, it is very scary to get angry. Although he knew that it should have nothing to do with him, Mitsuki Haihara was still so frightened that he couldn't speak.

The father, who sat down again, took out his mobile phone and made a call. After a few moments, the other side seemed to be connected. But my father didn't even listen to what the other side was talking to, and there was a burst of slashing on the spot, mixed with insults that were completely incomprehensible in Japanese and Russian. After scolding, it was almost completely like a roar.

It's scary! What's going on? Mitsuki Umihara had never seen his father get so angry.

From the fact that his father used Russian, Haiyuan guessed to whom his father was calling. But this scene is really surprising. It's hard to believe that my father would be so angry with his senior, and he seems to make the other party completely speechless.

After scolding for a long time, the father gradually calmed down, and he was talking to the other side in Russian. Although the tone is still not very good, the final result seems to be reluctantly agreed.

The father who hung up the phone took a deep breath, probably adjusting his emotions. After calming down a little, he said to Kaihara:

"Listen to Guanggui, I already understand the cause of your illness. You can't look at these things, at least not now. This is not an exhortation, but a warning. ”

In the words, there is a coercive force that absolutely cannot be opposed by Haiyuan.
