The next day Hiroki sat in his seat, calm and waiting for class to start, while two figures watched him: one with anger, the other with desire.
'I swear you pipsqueak, I will kill you whenever I get the chance!' Bert thought while glaring at Hiroki.
'Hiroki, you hid from me yesterday, but you can't run from me every time. Soon, I will claim you and make you my puppet,' Nao thought, smiling as she glanced at Hiroki. The classroom door opened, and Erika entered. Every student greeted her, and Erika responded with a smile, looking at everyone, especially the boy with blond hair and blue eyes.
'Yesterday, you humiliated the others, but this time, I will be the one who humiliates you.' Erica thought while looking at Hiroki.
"Class, before we start today's lesson, I've decided to give you all a pop quiz," Erica said with a smile. The whole class, except Hiroki, Bert, and Nao, shouted "No."
"Okay, first you, stand up." Erica points at a student, who stands up hesitantly.
"What is the chemical formula of water?" Erica asks
"Huh?" The student was surprised by the question.
"Don't you know the answer?" Erica said.
"I know, it's H2O." The student replied.
"Good, sit down. Next, you stand up and tell me what Newton's First Law of Motion is also called." The student stood up, happy with the simple question.
"It's the law of inertia." The student said.
"Great! Now, you." Erica pointed at another student and asked her another simple question. This continued for a while, with Erica asking each student a simple question they could easily answer.
"Now, Hiroki Mori, stand up and answer my questions," Erica said with a smile. Hiroki stands up and looks towards Erica.
'I knew you would do something foolish, but I didn't know this much foolish. Try everything you can, but you can't win against me.' Hiroki thought.
"Tell me the Organelle for photosynthesis and the key pigment," Erica said. The students in the class gasp.
"But Sensei, we didn't even read about them yet." A student said.
"Did I ask you the question? " Erica said with a piercing glare towards the student. The student goes silent.
"Tell me the answer, Hiroki kun, or go stand outside for the rest of the time,"Erica said, acting like she is angry, but inside she is laughing, thinking Hiroki didn't know the answer.
"Chloroplast; chlorophyll." Hiroki said, that shocks the class and Erica too.
'How did he know the answer?' Erica thought while getting angry.
"Great, Hiroki Kun, but you need to answer one more question," Erica said with a smile.
"Come here and write 10 derivatives on the board," Erica said with a smile. The students got confused and started gossiping among themselves.
"What is a derivative?" A student asks to another.
"I don't know," the other replied.
"Wait, I knew I read them in my brother's textbook, but it's for second-year students."
"Silent!" Erica said, and everyone stopped talking.
"Hiroki Kun, write 10 derivatives on the boards or go outside," Erica said with a serious look. Hiroki moves towards Erica and crosses her.
'Now stand outside for a while.' Erica smiled a little, but Hiroki stopped and moved towards the board, took the chalk, and started writing.ddx(x2)=2x\dfrac{d}{dx}(x^2) = 2xdxd(x2)=2xddx(3x3)=9x2\dfrac{d}{dx}(3x^3) = 9x^2dxd(3x3)=9x2ddx(5x4−7x)=20x3−7\dfrac{d}{dx}(5x^4 - 7x) = 20x^3 - 7dxd(5x4−7x)=20x3−7ddx(x)=12x\dfrac{d}{dx}(\sqrt{x}) = \dfrac{1}{2\sqrt{x}}dxd(x)=2x1ddx(1x)=−1x2\dfrac{d}{dx}\left(\dfrac{1}{x}\right) = -\dfrac{1}{x^2}dxd(x1)=−x21ddx(sin?x)=cos?x\dfrac{d}{dx}(\sin x) = \cos xdxd(sinx)=cosxddx(cos?x)=−sin?x\dfrac{d}{dx}(\cos x) = -\sin xdxd(cosx)=−sinxddx(tan?x)=sec?2x\dfrac{d}{dx}(\tan x) = \sec^2 xdxd(tanx)=sec2xddx(ex)=ex\dfrac{d}{dx}(e^x) = e^xdxd(ex)=exddx(ln?x)=1x\dfrac{d}{dx}(\ln x) = \dfrac{1}{x}dxd(lnx)=x1
"As you wished, Sensei, I wrote 10 derivatives. Did you want me to write more?" Hiroki said, looking at Erica. She got shocked, she never thought Hiroki could answer her questions.
"N-no, go sit on your seat," Erica said, feeling humiliated.
"Now, let's start the class," Erica said.
"Excuse me, sensei." A student said this with a serious expression as he stood up from his seat.
"Now, what?" Erica said, looking towards the student.
'The plan starts,' Hiroki thought.
"May I go to the washroom?" The student said, and the whole class started laughing.
"Silence! Why didn't you go before the class?" Erica said.
"Sensei, it's a nature call I can't control when it's going to come or not." The student said this, making everyone laugh and irritating Erica even more.
"Fine, go," Erica said and moved towards the board. The students start going towards the back door, but before he does, he looks towards the students near him and nods at them. When he reached near Bert's seat, he fell and made a loud sound, making everyone laugh again. The student stands up and looks towards Bert in anger.
"Why did you make me fall?" The student shouted at Bert. Bert got confused.
"What did I do?" Bert asks.
"Don't act innocent, you just spread your leg in my way to make me fall." The student said. Bert stands up furiously.
"I did nothing. Why are you accusing me?" Bert said.
"What is happening there?' Erica said.
"Bert spread his leg in my way to make me fall, sensei." The student said. Bert smiles, secretly knowing what will happen.
"Did you have proof of what Bert did, or someone who claims to have seen Bert doing it?" Erica said, and three students stood up.
"We saw it, sensei. Bert spread his legs to make him fall." Bert was shocked.
"Are you sure?" Erica asked, looking at them.
"Yes, sensei, we see him doing that!" The three said. Erica flinched a little. Four students are accusing Bert, and if she doesn't punish Bert, the students will become suspicious of her and Bert's relationship. Bert stood up from his seat and grabbed one of them by the collar.
"Shut up now, you bastards, or you will regret blaming me," Bert said
"See, sensei, he is even threatening us in front of you." Others said.
'What will you do, Erica? Will you punish your lover or let the others know about your relationship and get your career ruined?' Hiroki thought while seeing all this silently.
"Bert, go stand outside. We will talk later." Bert was shocked; his puppet was not supporting him.
"But I did nothing!" Bert shouts.
"Go stand outside now, Bert," Erica said with an angry expression.
"Tsk,"Bert clicked his tongue and went outside. Erica is sad and irritated, but she can't show it on her face, or everyone will get suspicious.
'Erica, you thought you could use your role as a teacher to contempt me, but I already controlled the whole class, everyone here have some secrets they can't told to anyone, I can use those secrets to blackmail them and make them do whatever I want and that's not all the videos of you and the others, Kaede left in my room sells in a huge price and that money I used to make those four following my orders. I just need to text them with an unknown number and send them some advance cash to make them do whatever I want, and you are in my control, too. The way you asked me the tougher questions and even asked me second-year level questions is something I already predicted and prepared for, but you forget that if you only ask one student difficult questions than others, it will make the students suspicious of why you do it. They will think that you have a grudge against me and how you try to protect Bert, who bullies many students and is famous for the many evil deeds he has done., If a teacher tries to protect a student like this, the other students will surely get suspicious.' Hiroki thought.
"Hey, didn't you find it strange that Erica sensei only asked Hiroki the tough questions? It's like she wants to ridicule him." A student whispered to another student.
"Yeah, it's definitely suspicious before Bert arrives, Erica sensei always shows a soft spot for Hiroki and for others, but now she acts cold towards everyone." A student replied.
"Now, you said it, didn't Erica sensei try to save Bert, and even reluctant to punish him?" Another student said.
"Hey, what are the chances Erica sensei sucks Bert?" A student said with a smile.
"It can be true, what if she has a relationship with him?"
"If it's true,then she has a very bad type, who wants to be in a relationship with that monkey; he always reeks, and that weird grin he has disgusts me and the other girls." A female student with a disgusting expression. In the meantime, Hiroki was listening to the students whispering and getting suspicious of Bert and Erica's relationship.
'The seed is already planted and gets enough water, now let's wait for it to grow into a plant I desire.' Hiroki thought.
