The love of functions and derivatives

The room where everyone sleeps in the party hall is set up early in the morning.When Function returned to his room, he felt uncomfortable no matter what he thought about, and even holding his mobile phone felt boring. The news in the mobile phone was not transmitted from his eyes to his brain at all, and Function just blankly posted for several hours. Take a look at the mess in your mind.

Going back to the original question, since the derivative concealed something after he woke up, does it have anything to do with his assassination?

The function also thought of the confrontation between Derivative and the delivery boy at his home more than a month ago. If the delivery boy was just an ordinary avenger, why did Derivative stop moving forward after hearing certain words? pace of?Why do you say that you have never met the delivery boy?

That video should still have some clues.

The function patiently read it from the beginning.

The video is only about 40 minutes long, but he was tired of watching the function in order not to miss a single detail. Unfortunately, he didn’t find anything. The progress bar of the video is obviously about to fail. The function is a bit decadent. In the scene of committing suicide, Function watched as his chest was stabbed with a dagger, and the blood stained the blade——

and many more!

The function immediately clicked the pause button, and he maximized the screen——

The delivery guy's blood is red.

He is human!

Then everything is easy to explain, including why he has a great hatred for him even though he obviously doesn't know him?Including why the police did not find his body after the takeaway boy committed suicide, because this was simply a way for him to return to the human world.

You ask me why the function knows this, because he has a good relationship with the tester of the college entrance examination, and the tester of the college entrance examination is also a human being, and he uses the method of "suicide" every time he goes back.Function has also sighed before, hey, this scene is a dream that many high school seniors and college entrance examination candidates hide in their hearts but dare not pursue!

The function also knows that some specific conditions are required to enter the world of high school mathematics textbooks, but the specific conditions are unknown.If that's all it is, why doesn't the derivative tell itself the truth?What else is he hiding?

Function sat tormented until [-]:[-] in the evening, which meant the beginning of the next day, and also meant the end of his pretend couple with the probability day. Function rushed out of his room and knocked on the derivative door.

He wanted to find out about the derivative.

Derivative opened the door, with tipsy red cheeks, saw the face of Function in front of him, and was about to close the door immediately, but fortunately, Function noticed it first, and put his palm in the crack of the door, Derivative moves a little slower, Function's palm will suffer inhuman pain tonight, but Derivative even stops the door: "You—"

Derivative is a little bit exasperated.

After the function came in, he found that there was a bottle of red wine on Derivative's bedside table with only one-third of it left. Derivative's pace was actually a bit staggering. He walked to the bed, sat down, and took a sip from the wine glass. , when he turned his head, it seemed that he suddenly found that there was another person in his room, and said to the function: "What are you doing here?"

Derivative drunk?

"Leave if you have nothing to do, don't disturb me for a drink." The derivative's head shook, even the wine in the glass in his hand was shaking non-stop.

Function wants to have a good chat with Derivative, but looking at Derivative’s state, I’m afraid it’s not easy to communicate, Derivative who is drunk is a bit arrogant and unreasonable, not to mention that Function can’t be sure that Derivative will remember what he said when he wakes up tomorrow morning?

"Okay, I'm leaving." Function said goodbye politely.

Function turns his back and walks to the door, holds the doorknob with his right hand and pulls it down. When he is about to turn it to the vertical position, a huge force pulls Function's body over and hits the door——

The thick aroma of red wine surrounded Function, and the scorching breath sprayed on Function's ears and neck. The shadow of Derivative reflected by the dim chandelier completely covered Function. Derivative grasped Function's shoulder with both hands, and exerted strength with four fingers.

Derivative's eyes fell from the eyebrows of the function to the bridge of the nose and then to the lips, as if tracing the outline of the facial features of the function with his eyes.

In the silence, the derivative suddenly said——

"That day at KTV, I sang the song "fools" to the window."

What does it mean to sing to the window?

Perhaps it was the smell of wine that was causing trouble, but Function suddenly had no thought of escaping. He raised his head to look at Derivative, revealing the line of his Adam's apple. Clear the emotions in the eyes of the derivative.

The two looked at each other for three seconds, and within three seconds, Function heard three tick-tocks of the wall clock and three beatings of his own heart.

Three seconds later, Derivative quickly leaned down, which should be a precursor to a kiss, but the moment his lips were about to touch, Derivative suddenly stopped.

"Why did it stop?"

Perhaps the dark environment can bring people great courage, Function asked while looking straight at Derivative's chest.

Derivatives are unanswered as the function expects.

Anyone who has a good relationship with the function knows the good temper of the function, but at this moment, the tone of the function is full of anger that can be heard carefully, but it is not known whether it is because of the derivative or because of himself.

"Then listen to me, if you hadn't concealed and deceived me—"

The function also didn't expect to get an answer from the derivative, he stretched out a hand to grab the tie of the derivative, and let the tie wrap around his hand, with a cold look, "Then the tie you are wearing around your neck now I should have sent you."

Function's hand holding the tie pulled forward, and the other hand hooked Derivative's neck, and kissed it directly.
