The love of functions and derivatives

It was not a kiss like a touch of water, it was a kiss that was menacing and full of catharsis. The two people clearly pressed their lips together softly, but they were both competing with each other, as if both of them hoped to pass this cross-border. The contact makes the other party perceive their own thoughts, and the breaths of each other exchange and whirl. After the kiss is over, both of them are panting badly. The experience of losing sufficient oxygen is still clear and palpable. Function looks up at the derivative, panting: "I and The relationship of probability is fake, it is probability that forces me to act as a boyfriend for a day."

When it's time to betray your friend, Function will never be the least bit soft-hearted, and then Function asks: "Now, it's your turn to explain how you lied to me."

Derivative's two beautiful eyebrows were about to come together because of frowning, and he looked a little naive because of being drunk: "When did I lie to you?"

Function laughed angrily: "Are you still stubborn? I have evidence in my phone."

The evidence of the function is the video recorded by the pinhole camera.

The derivative over there dragged the function and walked towards the bed in a daze. He didn't care what the function wanted to say at all, and said to the function, "Let's go to sleep."

The function was pulled by the derivative and had to sit by the bed: "No, if you want to sleep, you have to explain it clearly before going to sleep."

When the function sees the derivative, it is obvious that it does not cry when it sees the coffin, so it finds its own trump card from the network disk - video backup.Due to network problems, the video was loaded after the function was exited and entered several times. The function immediately gave it to the derivative, but found that the derivative next to it was already sleeping soundly.

Function's face is complicated: ... your sleep is really just sleep.

The function covered the derivative with a quilt, and went back to his room.

At [-]:[-] the next morning, the derivative and the function had a face-to-face meeting. The derivative got up at [-] o’clock because of the biological clock that goes to bed early and gets up early, but the function woke up at [-] o’clock only because of the math definition and the group next door who can stay up all night. The definition of language was really fun, and the function couldn't sleep after arguing all night.

Both of them had ghosts in their hearts, but Derivative's reaction was bigger. Derivative's expression after seeing the function was obviously hesitant to speak, and when he saw the other party, he planned to avoid himself. I haven't explained it clearly yet."

"Last night—what happened last night?" Derivative asked puzzled, "I just remember that you seemed to come to me, what happened afterwards?"

The expression of the function looking at the derivative thinking does not seem to be fake, it should be really forgotten, the function said: Alcohol is harmful, it is true.

But the function doesn't want to wait any longer, now is the right time, the function said firmly: "The problem is not big, then we should have a chat, what do you think?"

"Right on my mind."

There is almost no room in the party hall that is quiet. Even if there is, the room next to it is noisy. The dandruff falls down with the scalp, so the derivative takes the function to the yard outside the party hall, the small yard Very delicate, there is a path paved with cobblestones, the path is full of flowers and plants, and the path extends to a small woods in a winding way.

"Tell me, why did you lie to me?" The function and the derivative walked up the cobblestone path side by side, and he added, afraid that the derivative would deny it, "You obviously saw the delivery guy."

"I..." Derivative knew that he had to tell the truth no matter what this time, "Because he has a relationship with a person, and that person is a lunatic. If he knew about our relationship, he would torture you as well. I don't want you to be tortured." Get involved."

"That person? Who is that person?" Function asked.

"Yes—" Derivative was about to answer when he caught a glimpse of a silver light from the corner of his eye. In this flash of light, Derivative's body responded faster than his brain. He pushed the function away and reached out to the phantom at the same time. What should have fallen on the function fell on the derivative, "be careful—"

A section of the needle tube fell to the ground, Derivative was quick to step on the needle, and the black unknown liquid in the needle flowed out. Calm has returned to his eyes, "You are very smart, why not."

The delivery guy He Jie said indifferently: "You lied to me, and you are also very cunning."

Function recognized the takeaway boy at a glance. Even though he was wearing a mask and hat when delivering food, only a pair of eyes were exposed, but with these eyes, he would not admit his mistake. Function asked urgently: "You give the derivative What was injected?!"

The takeaway boy ignored him.

Function calmed down, called the hospital immediately, and called the police again after the call, even though he knew that calling the police was useless. After doing this, he stepped to see the wound of the derivative, but was stopped by the derivative: "Don't look."

"Are you OK?"

Derivative shook his head against the dizziness, but his face turned pale at a speed visible to the naked eye, and Derivative said softly to Function: "You have made all the calls you should make, don't say anything, don't do anything , leave it to me."

"you--"

Derivative stretched out his index finger and put it on his lips, making a silent gesture, and Function had no choice but to swallow his worries back into his stomach.The function quietly stood behind the derivative on the right, supported the derivative, and lent him some support.

"I knew you would come back." Derivative's tone was as calm as usual, but only he wanted it. If you can’t come, let’s talk.”

"Okay." He Jie smiled triumphantly, "Although I didn't succeed in killing the function, killing the derivative is also a windfall."

"But you lied to me." He Jie suddenly changed his face, becoming faster than the sky in June, "It turns out that the phrase 'I'm about to succeed' in He Jun's diary means this. A drop of ink can completely destroy you."
