[In a liquid or solid composed of molecules, the force that allows molecules to bind to each other is called () force.] 】

Kinoshita Hideyoshi's answer

[Cosmic Force (All forces in the world are made up of it, it is the universal force!!)]

Teacher's opinion

In the past, the teacher also had a time when he expected to be able to awaken to the Force and become a Jedi, but this was not enough to be a reason for Hideyoshi-kun to score...... Moreover, there is no such convenient force in the world as [universal force]!!

Yuko Kinoshita

【Van der Waals】

Teacher's opinion

Correct answer. It can also be called an intermolecular force. The van der Waals force is often mistaken with the Coulomb force generated by the combination of ions, so be careful.

Yuji Sakai's answer

【VanderWaals'force

- It doesn't matter what the molecular force is, Hideyoshi, let's get married, shall we?]

Teacher's opinion

============================= divider =============================

"Long time no see, Hideyoshi, Yuko. ”

The familiar black-haired hedgehog head, the teenager pulling a suitcase of luggage, greeted the two with a sunny smile.

"Ah, Sases, Friedes, Yuji-kun. ”

Yuko tried her best to show a quiet smile and beckoned to Yuji, looking elegant and quiet, full of girlish atmosphere. In contrast, Hideyoshi, who was on the side, reacted much more normally, and also responded to Yuuji's greeting with a smile.

So far, it is just a normal reunion scene between relatives and friends who have not seen each other for a long time, and the faces of the three people present are all soft and close smiles.

However......

As a black shadow that could not be seen clearly with the naked eye rushed over, the smiles on the faces of Hideyoshi and Yuko stiffened after a while.

"Long time no see, cousin...... Anyway, why do you suddenly hug the old decay?"

"Ah, I haven't seen you for several years, and as a childhood sweetheart and cousin, I'm shouldering a great obligation to confirm the growth of your breasts......" Facing Hideyoshi's somewhat troubled expression, Yuji buried his face in his chest as if he didn't notice it, and rubbed it, without the slightest intention of letting go.

No, no, childhood sweethearts don't have this kind of obligation, even if they are cousins...... Just as Hideyoshi's face was embarrassed and he wanted to correct this, the less and less pleasant touch came from his chest, but he couldn't stay calm like this anymore

"Wow~~, cousin, what are you doing......"

"As you can see, I'm very serious about checking your development!" Yuji said with a serious face, as if he was unaware of what he was doing, and he didn't even count, and then he commented on what was pillow on his face—

"Well, it's soft like brocade and tender like fat, it's worthy of being a dream place for beautiful girls in legends, it seems that Youzi's growth and development in recent years is good!"

"Eun, so I'm relieved. ”

“......”

Don't worry, you're a big-headed ghost!Yuko really wants to yell at the moment.,The name is innocently involved, not to mention being forced to watch this **** scene.,What the hell is going on!

The anger value has risen a lot unconsciously, and Yuko almost can't maintain her image. And the two idiots on the other side are still living and don't know whether they are alive or dead, and continue to accumulate pressure on her-

"Hmm~~...... Cousin, old decay, old decay is a boy, so there will be no boobs growth or something. ”

"Well, Yuko is talking nonsense again, how can it be a boy who is so cute...... It's not okay to be so awkward, girls must know some physiological knowledge of secondary sexual characteristics, and they must know how to protect themselves!"

"So...... Why do old people have to know the importance of secondary sexual characteristics?"

......

It is worth mentioning that this is not a remote corner, but a crowded station platform. Yuuji's unscrupulous movements and special words such as 'breasts', 'growth', and 'sexual characteristics' not only attracted a lot of attention, but also caused a discussion among the uninformed people around him

"Hey, the two people holding you over there should be boys, right?" asked one of the people in the crowd in a low voice to the person next to him

"Well, both of them are rare beautiful boys."

"Aha~~ The combination of a beautiful boy × a beautiful boy, the feeling of buzzing, this is really amazing!"

......

For some reason, this conversation is a little weird.

No matter what other people think, Yuko can't bear it anymore. Although as an excellent inheritor of [Kinoshita's Blood], her acting skills seem to have turned into instinct and penetrated into her bone marrow, helping Yuko play the omnipotent honor student at school and play the good girl in front of her parents, but this does not mean that Yuko likes to be watched like a monkey in a zoo.

"You two...... Give me a little bit of moderation!!"

Bang, bang

Separate and hold your head

"Woo~~ Sister, why do you even knock on the old decay?"

"That's right, you can't be so violent~~ Hideyoshi, we should get along well......"

"Hideyoshi, your sister! You're Hideyoshi! Your whole family is Hideyoshi!"

"Sister, I always feel that the old name has become a bad word for you?"

"No road race, no road race, no road race! It's not all you who did such shameless things on the street...... Yuko scolded as she pointed at the noses of the two of them with a red face, so angry that she couldn't even speak.

"What's wrong, what's wrong?...... We're cousins who love each other. (Note: What's bad? What's bad?—— from what Isayama Huangquan said to Tsuchinomiya Kagura in "Soul Eater".) ）

I want to ask, which cousin hasn't seen each other for three years, and they hit their chests as soon as they met? Is it a pervert? Is it a pervert? Yuko's forehead was bruised, and her fists clenched at the thought.

Speaking of which, Hideyoshi and Yuji are both boys, and it's not a big deal for a boy to hit a boy on his chest (it's about old chastity, so it's not a big deal, can you skip it?—— Hideyoshi), and as Yuko, who loves girls' novels, she should be happy to hear about this situation, but for some reason, Yuko just can't be happy.

No,It's not accurate to say that I'm not happy.,It should be said that Yuko is the only one who can't accept the cp composed of his younger brother and Yuuji.,Although both of them meet the standards of a beautiful boy in Yuko's heart.,But every time I look at my brother who looks very similar to myself.,Yuko feels like she's looking at another self in the mirror.,Now watching Hideyoshi being made like that by Yuji...... The shy action made Yuko can't help but be shy in her heart, and her whole body is so hot that she can't do it.

Yuko didn't want others to find out about her little thoughts, so she tried her best to hide her expression even though she was uncomfortable, although Yuji's eyes that kept looking up and down halfway made her a little hairy, but fortunately, the two people around her didn't seem to notice her abnormal appearance, and Yuko calmed down a little.

No, now is not the time to be reassured-

"What are you doing, staring at us all the time?"

"Ah, it feels a little weird......"

Looking at Yuuji's serious groaning, Yuko's heart that he had just put down suddenly pulled up again, and he heard his mother say that this guy seems to be the head of the grade in the general martial arts high school, and his head seems to be very good, could it be...... Did he really find out something?

"I think Yuko is my sister, right? But why does she call you sister again? and...... Yuko, why is she wearing men's clothes when she's so cute, what a waste, shouldn't she be wearing a cat-eared girl's outfit here?"

......

Hehe~~ I thought for a moment that this guy could see through everything, I was really a stupid......

And until now, I haven't noticed anything that has reversed my identity with Hideyoshi...... This kind of sluggishness is really infuriating, and I want to hit someone!

Yuko held her forehead and sneered twice, her fists clenched so much that she 'crunched'!

......

"So, my cousin made a mistake from the beginning, it's my sister over there, and it's Hideyoshi!"

Here, Hideyoshi, who can't bear the ravages of Yuko and Yuuji, finally tells the truth.

"Eh, liar!"

And then it was categorically denied.

Yuji said with a shocked expression, "My aunt told me before that Yuko has become a girl who is both gentle and lovely, kind and considerate, how can it be that kind of violent girl who is both rude and flat-chested, it is impossible for her spine to be crooked to both sides, and she is probably about to break......"

Finally, Yuko heard the sound of a string breaking in her head

"I'm a rude, flat-chested, and gentle and considerate violent woman, it's really right, no, up!"

Secret Technique - [Cross Fixing]

"Ah~~ It hurts, it hurts, it hurts...... I was wrong, I know I was wrong, Yuko is sorry!!"

"If it is useful to apologize, what else do you need the police to do, grit my teeth......"

...... Click~~

An overwhelmed voice rang out from the spine.
