[Deductor of Kagerome Hidden City] Happiness Theory

{Guiyin's perspective}

library.

"Have fun studying together☆(ゝ.)"

The library should have such an atmosphere—although the only ones who really need to work hard here are the two hard-working learners on the opposite side.

But different from usual, the place that has always been synonymous with quiet, now even the air seems restless.

"Because it's Valentine's Day."

It is said that the library is also in the top three of the "Campus Dating Spot Ranking☆～Let's enjoy a young relationship～", but what is more interesting is——

"Who came up with it?" Guiyin glanced at the couples. The sweet pink atmosphere surrounding them is almost impossible to look at. Although he said so, in fact... there is still something I'm jealous.

Guiyin glanced at Haruka who was sitting opposite, and sighed silently.

...still can't send it out...

"Happy Valentine's Day, Shintaro."

Fumino, who was beside Guiyin, smiled warmly, and handed the chocolate in his hand to the boy who was reading manga on the opposite side.

Well done Wen Nai!Thank you so much!In this way, you can take a nonchalant attitude "by the way, I also have chocolates that haven't been delivered yet", and then hand it to him casually, add a happy Valentine's Day and you're done!

"This is for Guiyin-senpai, happy Valentine's Day."

"Ah, thank you Wen Nai."

...Eh, wait.

Looking at the chocolates in her hand and that of the male group opposite, Guiyin discovered a fact.

"Is this Giri chocolate?"

The girl wrapped in a red scarf nodded, "What's the matter, senior?"

——The problem is huge!Fumino's life chocolate was not given to Shintaro? !

At the same time, something different about Wen Nai's body attracted her attention.

"No, it's nothing...By the way, Fumino, why did you make the scarf into a bow tie today?"

{From the perspective of Shintaro}

It is a very happy thing to receive chocolates on Valentine's Day. Even if there is only one piece of Giri chocolate, it is a personal acknowledgment for boys, so naturally they should accept it with gratitude.

But the mood is still a little subtle when I actually accept it.But it should be in the category of curiosity—to whom did Fumino get his natal chocolate?

Inexplicably agitated, Shintaro felt that he must have been affected by the atmosphere. Today's library has no way to calm people down.

"By the way, Wen Nai, why did you make the scarf into a bow tie today?"

Guiyin's words caught his attention, and only then did he notice that Wen Nai's scarf was not draped behind his back as usual, but tied into a cute bow, like a gift?

Wen Nai probably didn't do it himself, after all, it is more difficult to tie it from the back.

"Hey this—when is it?"

The surprised reaction of the person concerned also proves this fact, have you been teased?

"It was tied at home, after all, you were with me this morning, and I didn't see anyone doing such a thing."

"In that case...well, my brother should have done it."

younger brother?

Although I don't have a deep understanding of Wen Nai's family, I can be sure of the only child.

"Neighbor's?"

"No, he was adopted. He is a very cute child." When Wen Nai mentioned his family, a very gentle expression appeared on his face.

"Maybe it was put on secretly while I was making chocolates this morning...Because he kept asking me for my own chocolates, so I didn't pay much attention to his movements."

Takaon looked at Shintaro with a playful smile.

"Hey~ In other words, Fumino gave the chocolate of his birth to his adopted brother, and he even tied the scarf into a bow~ What a wonderful brother."

"Because he said that he wants to prove his charm, so he must want a piece of natal chocolate. This should have nothing to do with being powerful..."

"It should be said that it is really not to be underestimated."

The moment the words came out of his mouth, Shintaro was surprised by himself.

——like jealousy.

{Wen Nai's perspective}

Turn the time back to morning.

I got up early today to prepare chocolate.In fact, she didn't have any beautiful ideas about the meaning of the festival itself, but just wanted to take this opportunity to thank the seniors and him for their care.

So, just prepare giri chocolate.

...feels a little sad.

It's not like there aren't people who want to deliver Honmei Chocolatier.But, no.

What he needs is someone who can hold him back.Standing at the current position, just keep watching, and Shintaro cannot be involved.

"Sister Wen Nai," what are you doing so early? "

Because of her age, her arms were slightly slender around her waist, and her head rested on her shoulders. She could feel the other person's breathing.

In short, it was being hugged from behind in a very intimate gesture by others.

"Kano? Why did you wake up so early?" After picking up his mood, Fumina asked with a smile. Although the current posture is a bit too intimate between siblings, but because he has been watching Kano grow up, for Fuminai, It's just because of Kano's acting like a baby.

So, quite peacefully accepted.

"This is a problem from my side... Because I am a little concerned about Miss Wen Nai, so I got up and took a look."

"I'm sorry, but I still disturbed Kano. Today is Valentine's Day, and I want to make some chocolates for my school friends."

"Valentine's Day...that's true. Ah, Fumino-san, who is going to prepare the natal chocolate for—"

He looked at Wen Nai with sharp eyes that were probing.

"Benming chocolate or something, nothing, nothing!"

It should be said that it has been given up.But I still feel embarrassed when asked.

"Well, since sister Wen Nai said so, then give it to me."

There was an unreserved smile on Kano's face, for some reason it was impossible to refuse.

"I really want my own chocolate."

"——No, Kano. Chocolate is a confession that a girl gives to a boy she likes. Take the chocolate I gave you, and it might make the girl who likes you sad."

Although I don't know why Kano made such a request, but if some things are not good, they are not good, and we must tell him clearly.

"...Sister Wen Nai, I'm not the kid who didn't understand anything anymore."

However, unexpectedly, Kano did not give up.He looked at her with uncharacteristic seriousness.

"I've grown taller. Although I'm about the same size as Sister Wen Nai, I'm out of the scope of a child. It's okay to hug Sister Wen Nai."

"So, sister Wen Nai, please take a closer look. How am I now? I'm not willing to stay in the category of my younger brother."

Low voice, as if suppressing something.

"—"

I don't know what to say, so I made an unexpected statement.

It's not that I didn't notice it, but I ignored it subconsciously. Because I always played the role of my sister, I always looked at him with the same eyes. Of course, there is also a relationship that we get along with each other day and night. Speaking of which, when did we stop sleeping together? ?In short, it is quite a natural separation.

"...Time flies so fast."

The exclamation made Kano understand Fumino's thoughts in an instant, because she never changed.

"Yes, I don't know if you are too cunning or too slow to say sister."

"Hey, why do you say that?"

"In short, it's my sister who is not good. It's too much. She always treats me like a child-so give me the chocolate of my life! As a testimony of growth, I received a gift from the opposite sex at the first step of growing up. chocolate!"

"But wouldn't the sister give it look miserable?"

"I want it, so please, Wen Nai."

"I want to add my sister."

"It's not bad to feel like this once in a while, it has a feeling of intimacy."

So, in the end, I gave him the natal chocolate.

"Don't cry."

"Why do you say that?" Kano asked puzzled while holding a heart-shaped chocolate with obvious festive atmosphere.

"Because Kano looks sad. So, I want you to laugh."

"..."

Something soft and slightly cool was attached to his cheek - near his lips.

Kano kissed himself.

It only takes a few seconds to leave.But the aura that belonged to him has always surrounded her.

"Happy Valentine's Day, Sister Wen Nai, thank you for your natal chocolate, it was a gift just now."

My important brother smiled and said softly.

{kano perspective}

I'm watching.

I'm not old enough to go to school with my older sister, but it's easy to use if you just come in.

But he made such a behavior similar to a stalker - he really wasn't that kind of bad person, he just wanted to prove it with his own eyes out of a sense of competition.

Perhaps it is better to describe it as a declaration of war.

I really like the idea of ​​declaring war, and I feel like I have become my sister's favorite person.

So you are aware of it?

Although I don't quite understand what happened, but I should have this awareness—even if Wen Nai likes you very much, there are still competitors, and I don't have such a broad mind. Of course, the happiness of the person I like depends on myself create.

So -- again oh, listen up.

{From the perspective of Shintaro}

"I won't give Wen Nai to you."

For a moment, it seemed that someone was saying that.But I didn't find any suspicious person when I looked around. It should be my own illusion, because of her.

It seemed that he remembered something, his face burned all of a sudden, but he kept being teased by Guiyin-senpai, is it a girl's friendship?

The mood is still very irritable, although it has been well covered up just now.

and many more……

I accidentally saw a girl who was about to walk out of the library. Her hair was blond. I felt like I had never seen it before. Is it from our school?

As if she had noticed something—it should be said that it was a specially prepared coincidence, she turned her head and met her eyes.

"No, I'll leave it to you." The girl said so, this time it was not an illusion.

--What's going on?

Although I don't quite understand it, I can still feel the hostile feeling.

—Is it a declaration of war?

{kano perspective}

In the pocket is the natal chocolate given by Sister Wen Nai, and the packaging is also very good. Although the taste is a bit bitter, it feels very sweet, just like tasting my sister's favorite.

Even though it is very clear that this should belong to another person, sister Wen Nai did not give it to him, so I fought for it with my own hands - it belongs to me.

"Although it's cunning, I won't let it go easily."

Hey sister, when will you find out my true emotions?

{? ? ?Angle of view}

"Wen Nai, can I ask you a question?"

"What's wrong, Shintaro?"

"Your brother...does he have strange hobbies like transvestism?"

"—"

Boom!

"How is that possible!"
