A Salted Fish in the Second Dimension

So Hanyu happily went to play games.

……

……

Monday, make-up exam classroom.

"Takasaka-san."

"Hanyu listens to the snow."

Hanyu and Takasaka Kyosuke did not sit very close to each other. Instead, they were at the front and last tables on the outer side of the classroom.But that didn't stop them from making intense eye contact.

"Da da da da... (Takasaka-san, are you ready?)"

"Da da da da... (Hanyu-san, received. Everything is ready, only the east wind.)"

Before the exam, the two used their own secret techniques to tap the desktop to conduct a pre-exam experimental exchange.

After that, Hanyu, who was ready, calmed down.

"Da... Da... Da..." A sound of high heels stepping on the ground came from outside the classroom.The classroom door was opened, and the invigilator walked in.

When Hanyu saw that the invigilator who came in was actually Hiratsuka Shizuo-sensei, he panicked.

"Da da da da... (What should I do? If it's her. Will we be found abnormal when we tap the table. Hanyu classmate?)" According to rumors on campus, Hiratsuka-sensei will get a lot of things, two People aren't sure if tapping their modified Morse code will be found.

Hanyu began to think about a solution.

Suddenly, Hanyu saw that the sun was a bit strong today. The metal buttons on his clothes reflected the sun's light, forming a light spot on the ceiling. His eyes suddenly lit up and he had an idea.

He scratched his head and looked at Kosaka Kyosuke, and after the two looked at each other, he motioned him to look at the ceiling.Later, I saw that Kosaka Kyosuke noticed the light spot on the ceiling, and then Hanyu passed a message to Kosaka Kyosuke by blocking the light of the metal button.

"... (We rely on the light spot above to communicate information, so there is no sound.)"

"...(Received, understand.)"

"... (But since her opponent is her, this method can still be used without it.)"

"……(clear.)"

Then Hanyu didn't know that his little actions with Kosaka Kyosuke had been watched by her since Hiratsuka-sensei entered the classroom.Hiratsuka Shizuo-sensei couldn't help showing a disdainful smile.

"Okay, be quiet. The exam is about to start. This time it's a make-up exam, so you all know the consequences of failing the exam this time, so I won't say anything more. Do the test." After explaining the pre-test matters, Teacher Shizuka Hiratsuka distributed the papers and waited for the bell to ring to officially start the test.

After Hanyu finished the paper, he immediately read it again.Luckily, it seems that it is not very difficult to read the paper for the make-up exam. Hanyu feels that it should not be a problem to write most of it.

However, Hanyu was not very confident in himself, so he thought about adjusting the eraser and drink he had prepared so that he could see the formula posted on it more easily.

"Hey, Hanyu-san. The teacher is a little thirsty. This bottle of drink is borrowed from the teacher and will be returned to you later." Before the exam started, Hiratsuka-sensei came to Hanyu's side, and took Hanyu's drink without waiting for Hanyu to say anything. The drink was drank, and instead of drinking it all in one breath, he took the drink and returned to the podium to drink it without a sip.

Hanyu smiled when he saw Hiratsuka-sensei's playful expression when he looked at him, Hanyu felt guilty.He signaled that Teacher Shizuo Hiratsuka was free, not to be polite to himself.

And Kosaka Kyosuke, who was sitting at the back of the classroom, felt a little guilty when he saw what happened in front of him and moved his drink, hoping that Hiratsuka-sensei would not notice him.

The bell rang, and the classroom reverberated with the rustling sound of the tip of the pen rubbing against the surface of the test paper.

Hanyu wondered if Hiratsuka Shizuo-sensei noticed that he had done a little trick on the packaging of the beverage bottle.So I answered the question in a panic, for fear that Teacher Shizuo Hiratsuka would suddenly say to me that he failed in cheating.

Finally, after writing for a while, Hanyu breathed a sigh of relief when he saw Hiratsuka-sensei threw the finished beverage bottle into the trash can.Then the mind became active.

Looking at the topics I have written, most of them are basically written.Forget the score, if you write correctly, then you will pass.

Then Hanyu really didn't have confidence in himself, so he was going to ask Kasaka Kyosuke to 'communicate'.

First of all, Hanyu coughed, then put his metal button under the Yangguan, reflecting a light spot on the ceiling, and then after seeing another light spot, he knew that Kosaka Kyosuke had already received his message.Hanyu began to communicate.

"...(Multiple choice, check.)"

"... (Wait a minute I'm not done yet.)"

"...(Notify me when you're ready.)"

Then, without waiting for the two to communicate again, Hanyu saw Shizuo Hiratsuka tapping on the podium rhythmically with his fingers.

"Da da da da... (do the questions yourself, don't think I'm blind.)"

Hanyu was about to cry, but Hiratsuka Shizuo-sensei was also an understanding person.

……

……

"Jingle Bell……"

The bell for the end of the exam rang, and Hanyu wanted to struggle on the paper again, but unfortunately, Teacher Shizuo Hiratsuka took the paper away mercilessly.

"Okay, today's exam is over, and the results will be known tomorrow. Hanyu-san will stay, and the others can leave."

Hanyu was a little flustered when he heard that Hiratsuka Shizuo-sensei wanted to leave "instruction alone".

After everyone else in the classroom had left, Hanyu stood in front of Hiratsuka-sensei with his head bowed.

"Really, there are so many crooked ideas, can't you put your cleverness in your studies?" Seeing that no one was there, Teacher Shizuo Hiratsuka broke down Hanyu's careful thoughts.

"Teacher...I..." The guilty Hanyu was a little confused and didn't know what to say.

"Forget it, for the sake of learning Morse code, I'll let you go this time. But there's no next time."
