My girlfriend is actually myself.

Chapter 6: Studies on Children...

II. Symptoms of Twins (Observations and Summary of Two Bodies)

Shiraishi Saku continued writing his observation report.

[1. The two bodies can be controlled separately, which is more convenient and intelligent than controlling both hands.]

Shiraishi Shuo circled the word "intelligent".

While he continued writing in his journal, the girl in the house turned off Google and opened the game interface.

One of them held a pen, pondering the strange occurrence of twins, while the other controlled a game character, wielding a broadsword to challenge a boss. They each did their own thing, thought their own thoughts, and did not disturb each other.

But both he and she could feel the mechanical pencil and game controller on the other side, as well as the flow of information passing through their minds.

Both hands can work together, but cannot work independently. They cannot draw a circle with one hand and a square with the other. Even if they could, the drawing would be crooked and messy. However, Shiraishi Saku and Yukimiya Natsune can each have their own tasks: one writes a report and the other plays games.

It felt like I had two brains.

They did indeed have two heads, one with short black hair and the other with long golden hair hanging down.

Why is he here struggling to write his journal while she's over there happily playing video games?

Such a thought had barely arisen before it vanished, failing to stir even the slightest emotional ripple. Just as the right hand doesn't feel that the left hand is lazy, the feet don't feel that they should stay on top and let the hands walk.

Whether it's the boyish form of Shiraishi Saku or the girlish form of Yukimiya Natsune, they are a single entity. The only difference between Shiraishi Saku and Yukimiya Natsune is their left and right hands. It's somewhat like a collective life form in science fiction.

Shiraishi Shuo continued writing.

2. Distance doesn't seem to be an obstacle, at least not for two kilometers.

He was at school, she was at home, less than two kilometers apart, but they didn't lose contact and she didn't feel any discomfort.

Let's test the latency.

Shiraishi Saku took out his phone from the desk drawer and turned on the online clock. At the same time, Yukimiya Natsune also turned on the online clock on her computer.

At exactly 9:30, he thought of a number in his mind, and Yukimiya Natsumi immediately typed it on the keyboard. When the time was displayed as 09:30:01, a 6 appeared on the screen.

In a second, the numbers traveled from Shiraishi Saku's mind to the screen in front of Yukimiya Natsune. Subtracting the reaction time of both bodies, the delay was negligible, at least over a distance of two kilometers.

Shiraishi Saku moves on to the next item.

[3. Simultaneously controlling two bodies, no additional energy expenditure was felt.]

In many works, controlling another body comes at an extra cost, such as being prone to hunger or mental exhaustion. This is not the case with Shiraishi Saku, at least not yet.

4. The sensations on both sides are completely synchronized.

This needs no verification; Shiraishi Saku has always felt a heavy weight in his chest.

5. The sensations on both sides are layered; they don't overlap or overlap.

The bell had rung for a while when Shiraishi Saku entered the washroom and placed his hand under the faucet. The water flowed over his fingers, bringing a slightly cool sensation.

Meanwhile, at home, Yukimiya Natsune found an electric heater, plugged it in, raised her arm, and felt the heat seep into her palm, making it a little hot.

The sensations of hot and cold did not cause sensory confusion for them. They could feel both cold and hot at the same time, but they could also clearly distinguish where the cold and hot were located, without experiencing sensory disorder such as their palms being both hot and cold.

Back in the classroom, he wanted to continue with the sixth rule when a girl came over.

She was a member of the popular group in our class. I forgot her name, but she was just a high school student, yet her makeup was very elaborate.

With this makeup, she stood out among the girls and was known as the most beautiful girl in the class.

At this moment, this number one beautiful girl stood in front of Shiraishi Saku.

"Shiraishi-kun, you were so handsome just now. Do you like history?" The other person's voice was sweetly formulaic.

Shiraishi Saku wasn't interested in girls who exuded affectation from the inside out, and coldly replied, "Not interested."

Normally, people wouldn't know how to respond when they get here, but this is no problem for this number one beauty.

"You're not interested at all? That's pure talent, amazing!" The girl covered her mouth, feigning surprise.

It has to be said that the other party is very good at talking and providing emotional value. If it were any other innocent young man, he might have fallen for it.

Shiraishi Saku is no innocent boy; aside from anything else, his own girlish body is much cuter than the other's.

Ignoring the other person, Shiraishi Saku continued to ponder the sixth point.

The girl was given the cold shoulder, so she wisely left.

Two boys who had been observing from a distance took chairs and sat down on either side of Shiraishi Shuo.

They were people Bai Shishuo knew, and also two parasites who had just been arrested by their homeroom teacher.

Shiraishi Saku didn't plan to play the game of friendship in high school, so he didn't make any friends. These two boys were tools he chose to prevent himself from becoming too detached from the small society of the class and attracting unnecessary trouble—Japan's school bullying is notorious.

Their relationship was nothing more than this: Shiraishi provided them with completed assignments, and in return, they provided Shiraishi with information about the class.

It's been almost a month since the start of the first year of high school, and the small cliques in the class have basically solidified. Shiraishi Shuo is considered to be affiliated with the group that the two of them belong to, belonging to the circle of marginal people in the class.

One of them is named Shota Tanaka, and the other is Kaito Inoue. They don't have any special talents and usually like to talk about games and comics.

However, this pair of shut-ins actually have a heart that longs to be more like a normal person.

"Shiraishi, you're being far too cold to Shimizu."

"You're the only one who would treat Shimizu like this."

The two sighed to Shiraishi Saku.

Over the past month, they have basically come to understand Shiraishi Saku's personality. This handsome young man, who could easily join the ranks of popular people, has absolutely no interest in girls.

This made them sigh with regret, lamenting that the other person had truly wasted that face.

If they had that face, they would have long since escaped their marginalized status and indulged in the decadent life of the "normative."

"I heard that Shimizu has dated many boyfriends and has even done 'that' kind of thing," Tanaka Shota said in a low, mysterious voice.

Inoue Kaito chimed in, "If you date her, Shiraishi, you can do that kind of thing too."

Shiraishi Saku glanced at the longing on their faces and sighed, "You two are practically walking criminals."

The two whispered in defense, "This is our first time being in the same class as girls, it's normal to be a little excited!"

"Our goal is to graduate from magic school in high school and enjoy our youth to the fullest!"

They graduated from an all-boys school together, and for three years of junior high, they were surrounded by male students.

The phrase "graduating from a magician" is an internet meme, referring to the idea that a virgin who lives long enough will become a magician. "Graduating from a magician" means losing one's virginity.

Shiraishi Saku could understand their emotions, but he couldn't agree with them.

He twirled the pen in his hand and advised, "After you get married, you'll realize how precious your current life is."

The bell rang for the second period, and they all returned to their seats. Shiraishi Saku continued his experiment.

Under his control, Yukimiya Natsune lay on the bed and drifted into a sweet dream, while Shiraishi Saku remained awake and conscious.

He erased the five summaries in his notebook and re-summarized them into one.

[Two bodies, independent of each other, yet belonging to one whole.]
