Speaking of the height of summer, it is inevitable that people will recall some painful experiences.

The scorching sun melts the whole world, and the sky and the earth seem to be only the intense incandescent color, walking on the streets, the body has to accept the scorching heat from the sun and the scorching air directly into the lungs, and even on a peaceful night, we have to bear the 'buzz' of mosquitoes in our ears......

And girls seem to have more reasons to hate summer, eating snacks in summer is more likely to have diarrhea, too strong sunlight will sunburn the skin, high temperature will cause heat stroke, plus a little exercise sweat will wet clothes and become sticky, for the day ** clean girls, there is probably nothing more unbearable than this.

However, even so, midsummer is still the most popular season for students!

The reason is clear as long as you listen to this sentence - as long as you are a student, you will not hate summer vacation.

That's right

It's summer vacation!

Compared to the winter vacation, when the cold breeze makes people want to spend time in a warm stove, and the spring vacation, when they are busy visiting relatives to welcome the New Year, the summer vacation with good weather and free time is undoubtedly more popular with students.

Summer vacation activities for Japanese high school students are generally exciting, after all, there is more than a month of free time, which translates into nearly a thousand hours. At this time, traveling with the whole family, playing with friends, and dating the girl of their choice have become commonplace options for ordinary high school students, not to mention large-scale festivals such as Obon and fireworks displays.

Summer vacation is a student's paradise, almost that way.

However, none of the fun options mentioned above such as "playing with friends" or "festivals" mean anything to Yuuji as an outlier.

Since elementary school, he has closed himself off, and every day he either studies basic subjects or studies human psychology, and the beautiful student years have passed before he has time to enjoy a moment. Perhaps for him, the word 'summer vacation' probably only exists in the most distant memories.

As a student, I've never enjoyed the summer vacation.,Of course, it's a pity.,But all of this has a chance to make up for it with Yuuji now becoming a high school student again.,Although the process is a little wonderful.,But Yuuji, who became a high school student again.,Naturally, there is also a chance to enjoy a great leisurely summer vacation.。

However,

"Report, telomeric reverse transcriptase antisense oligonucleotide labeling is successful, does it start targeted imaging?"

"Well, let's get started, but remember to send me a copy after you back it up. ”

This is a biotechnology research institute located in Chiba Inage Ward.

Looking down through the large screen glass of the observatory window, you can see researchers busy operating between more than a dozen precision instruments, and Yuji, who is standing on the glass-isolated observatory to give instructions, is dressed in a white coat + black-framed flat glasses at the moment.

"No, the display resolution is insufficient!" The image is blurry...... "The young trainee looked in the direction of the glass table in a bit of a daze, asking for instructions from the teenager who looked younger than himself, "What should I do, senior?"

In fact, in addition to the director and deputy director of the research institute, there are usually only the people in charge of each research project who can stay at the observatory and work regularly, so it is no accident that Yuji can work here.

As the person in charge of this research project, Yuuji is responsible for the conduct of the experiment.

"Is it a lack of resolution? Try adjusting the magnification parameter upward, if not...... Ikati-kun, please change the cross-sectional height and then take a look. ”

The two of them who received the instructions agreed, and then began to operate, their fingertips lightly tapping the buttons, as if they were accustomed to the young man's instructions, and no one in the laboratory objected. For a while, in addition to the dull and monotonous hum of machinery, a patchwork of keyboard music was added to the laboratory.

To become the person in charge of a project at the age of sixteen or seventeen, Yuuji must be lacking in qualifications, but fortunately, this weakness can be compensated for with ability, although this often means a heavier burden.

"No, no~, the image is still blurry!!"

"Still vague...... Hus?" Looking at the blurred mark colors on the display, Yuji frowned slightly

The staining is blurred, but the distribution is characteristic. And the number of telomere genes is also quite interesting! It seems that it is not related to the staining of specimens, in this case......

"Try it with chelating agents instead!"

After revising the experimental plan in a moment, Yuji supported the workbench with both hands and calmly gave instructions for the next step.

"G-ore labeling of full-stranded thio-modified hTERTASON (with a primary ammonia attached to the 3' end) and preparation of antisense probes for in vitro experiments, we switched to MRI!"

"Huh?"

Suddenly changing the experimental plan was of course a troublesome thing, and even if several assistants worked together, and even Yuji himself helped to bring in new trainees, it took a long time for everyone to start the experiment again...... But it turned out to be worth it.

"It's done, it's done! The image is clearly displayed!!"

Looking at the textbook-like pictures on the monitor, the new trainees couldn't help but feel a little excited. However, Yuuji knew very well that the solution was only a small problem in the experiment, and it was far from success, so he just made a quiet announcement

"Experiment, move on to the next one!"

"Yes!"

......

This is the daily routine of Yuuji's summer vacation.,There's no option to go out with friends.,It's not like in the comics.,Go back to your hometown and find an apostle or something.,And then forced by a mysterious organization to drive a super giant robot to constantly fight monsters.,Fighting.,When you're about to win, you find that you've fallen into the ...... of 'human orange juice plan' - such a plot unfolded by God.,It's as boring as an office worker.。 After breakfast with my family in the morning, I spent my mornings and afternoons at the institute, and occasionally worked overtime to do research, just like Yuji did in the United States.

The only thing that makes Yuji feel fortunate is that he can see his lovely sister and gentle mother when he returns home. Being able to chat and watch TV with your family, spend a simple night together, and live a dull and warm life, instead of going back to only face a deserted room and say 'I'm back' like a heart-filled emptiness.

To be honest, he was doing the same thing as before, completely forgetting his original goal of finding something, and Yuuji also knew that his behavior at this time was very ridiculous and stupid, but what could he do? If there was any other choice, he probably wouldn't do it.

After that day, although he still came to school with a confident and awe-inspiring expression as usual under the snow, and still fulfilled his duties as a minister and came to the ministry first, under that normality, Yuji was able to clearly perceive some changes in the ministry department.

The department is still the same classroom as before.,The personnel are still those familiar faces.,Even the daily life of talking and chatting hasn't changed.,But Yuji, who is sorry and wants to apologize.,And Yukino, who keeps his distance and resolutely doesn't forgive.,Whenever these two people come into contact.,The atmosphere becomes obviously bad.。

So, I can only rely on Yui, who is sleek but can't solve the problem, and Biqigu, who is withdrawn but understands people's hearts, to be a buffer between the two. The former 'ministry ministry' is broken and can no longer be healed.

It is undeniable that Yuuji has already realized the fact that 'his existence has become a 'foreign object' in this department, which can only cause embarrassment to the other three. So, he 'left'.

Although for the next month, Yuuji would still show up in the ministry every day and talk to everyone as usual...... But the place where he existed was no longer there.

Perhaps, the busy days now are not bad, at least the life spent every day is full, and it can fill the vacancy in his heart a little!
