"It's supposed to be a math problem." I said.

"What the hell should it be? What about math problems? The sea said.

"This is for you to solve. Don't you understand? I said.

"Well, I don't understand it, but I know it. You asked me to look it up on the Internet, and I'll have it on the Internet for a while. You don't know that everyone on the Internet has it, and everyone is talented. They speak so nicely, I like them so much. The sea said.

"You can't send it, don't mess around." I said anxiously.

"Is it the Bitcoin password? This cannot be asked. The sea said puzzled.

"Anyway, it's very mysterious, you can look it up. If you can't find it, forget it, remember not to send it out. I said.

"Okay, I'll check. I don't think I have much chance of unraveling this stuff. The sea said helplessly.

"Then keep in touch." I hung up the phone.

It seems that the sea is not passable, and there are no math experts around.

I watched this string for almost the whole night, and I didn't understand anything.

The next day, Usu was still sitting in his original seat in the library, and he made a greeting between his eyes and me, but he just waved his hand and didn't speak, and I was a little embarrassed.

Didn't speak, as if nothing had happened. Is that string of code just for me to give up? Or is there really something hidden inside?

I looked at Usu, and Usu continued to look at the astronomy book.

I wondered, maybe this isn't a math problem? Could it be related to astronomy?

A certain coordinate? Or is it the number of a certain planet?

I don't seem to know anything about celestial bodies?

So who can I go to? It's better to go to a teacher who teaches.

I immediately got up to leave, and when I looked back, I glanced at Usu.

I saw that Usu was also looking at me, and I smiled.

I immediately walked out of the library and rushed straight to the astronomy classroom.

The class schedule posted on the door told me the exact location, and it seemed that the first-year students were starting classes.

When I arrived at the door, the bell rang just after class.

The students poured out, and by the time the students were almost gone.

I saw a tall figure packing up the courseware.

I immediately ran in, and my legs went weak when I saw the teacher who was teaching the class.

Because the teacher's face is really cloudy.

I haven't met Usu's father, but the person in front of me really matches the word cloudy.

Of course, it's hard for me to imagine how such a strong teacher can give birth to such a quiet daughter.

Daughters are like mothers, daughters are like mothers. This time the word came to my mind, and it kept circling.

At this moment, the dark clouds seemed to see me and said, "This classmate? What are you doing here? ”

"Huh? Like Mom. I blurted out subconsciously.

"What mom?" The clouds were thick and he said incomprehensibly.

"No, no, no, teacher. Oh oh oh, Professor. I have a question here, and I hope you can help me see what it is. I said nervously.

"Oh? Question for me? Everyone left in a hurry after my class, and it was rare to see anyone who came to ask questions after class. It's rare to have someone who really likes this class, why haven't I met you? The clouds covered and he stretched out his hand.

I turned around my backpack and just as I was about to take the letter out of my bag when I remembered that there were words on it.

I immediately put down my bag and tightened the zipper.

If the crush Jun looks up and makes the clouds see it, I won't be dead if I still recognize the word.
