I turned around and saw Oxygen standing up, wriggling and saying, "Huh? Is it my turn? I'm oxygen, the one that everyone breathes every day. It can help the flame burn, right? Insoluble in water, colorless and odorless? I'm sorry, I didn't do well in junior high school. ”

。。。

It's the first time I've thought a girl can be so cute, and they don't seem to have been in my world before. The other party seems to have appeared out of nowhere. And now I want to know each other's names and know everything about each other. But apparently I don't know anything, but there should still be a chance.

I was thinking about introducing myself in the next class, and I was sure that I would know who Oxygen-san was.

。。。

Her surname is Wu, and her name is Wusu.

I don't know anything else, except that she was sitting behind me on the right.

In the following week, many students in the class fell in love with Einstein's class because it was so vivid.

But I fell in love with Einstein's oxygen and felt like it was all I had.

There is an essential difference between Einstein and the previous principal's aunt, or it is completely heaven and earth.

The former uses what they know and learns to create, while the latter uses what they know and learns to repeat.

What Einstein did was to make even those students who were a little weaker in the back row know the elements they represented, and even to review and self-study in advance.

And Einstein also likes to learn the knowledge points of any elements, and let whoever comes up to perform vividly.

This is the most vivid thing in Einstein's class, because the common elements in textbooks at that time were: hydrogen, carbon, oxygen.

Sometimes when it comes to certain lessons, these three students who act as elements can stand on the podium for the entire lesson without getting down.

And you can only perform one element by yourself, sometimes you need one or two oxygen or two to four carbons or something like that. The students who performed also had to hold their right hand pen high to draw their own numbers, but not to mention that other students learned really fast enough.

And I only have Wusu in my eyes, or only this lovely oxygen classmate.

I could look at Usu on stage for a long time, especially when Usubi Scissorhands.

I don't know if it's a delusion, but I think Usu's hair is better than the other girls in the class. It was brighter and darker, and even when Usu returned to his seat, I could smell a unique smell.

It was an indescribable scent, faint and smelly.

I used to check it on my phone, and some people said that it was the peculiar smell of milk on girls. Some say it's the smell of laundry detergent at home, but of course I believe in the former more.

After all, I knew in my heart that I could only smell it on Usu, and of course it was possible that the taste was enhanced by the liking of the mind.

Of course, there are some problems, such as the fact that I can't see Usu at all, except for Einstein's classes.

Normally, Usu sat behind my seat, and it was impossible to turn his head 180 degrees all the time during class.

I do that a lot, but it's awkward to turn around and meet a pair of eyes.

I was embarrassed to turn around, and I couldn't help but want to turn around again.

But they were all discovered, and it was impossible to turn around again.

In order to solve the problem of turning my head to look at Usu, I expect two things to happen almost every day.

The first thing is that the teacher gets down from the podium and walks down the stage, so that he can follow the teacher and peek at Wusu in the interval. But most teachers don't step down at all, and I've only seen English and Chinese teachers read aloud to students.
