"Today's lesson is over."
Putting down the whiteboard marker, Ren said this to the seven of them.
Even though there were four more people taking lessons compared to before, he still didn't extend the lesson time too much and kept it almost the same as before.
Gabriel was still waiting for him to come back for dinner, he didn't want Gabriel to wait too long.
"It's over, so fast."
Ichika came back to her senses and could only sigh.
When she was in school, days could be said to be like years, and every class was painful. But when she listened to Ren's lecture, she couldn't feel the passage of time at all. So fabulous.
"That's right." Nino next to her narrowed her eyes and looked at Ren.
After chatting with Naoki just now, her inexplicable sense of familiarity with Ren disappeared, so she no longer struggled with her strange feelings for Ren.
While they were still talking calmly, Ren took out a stack of A4 papers from his school bag and handed them out.
"What's this?"
Taking out the A4 paper and looking at the math questions on it, Miku asked in confusion.
"You will practice after class."
After carefully considering his words, Ren gave a suitable explanation.
"Eh? Kamikawa-san, did you make this?"
After quickly confirming the title, Fumino confirmed it in disbelief.
"Yes, doing this can speed up your problem solving speed."
Ren nodded.
After taking the exam, he heard Fumino and the others say that they could do the questions themselves, but when their time was limited, he came up with an idea to help them increase their speed in doing the questions.
It just so happens that he also agreed to help Ichika and the others with tutoring, so he created a set of exercises from scratch based on his own understanding.
What he sent now was the most basic part of the series of questions, and also the content he had just finished today.
In this way, not only can it help Ichika and the others improve their basic skills, but it can also help Fumino and Rizu improve their speed in solving problems, so as not to be able to solve problems next time. It could be said to kill two birds with one stone.
"Truly?"
Itsuki took it carefully as if she had found a treasure.
"Isn't this Kamikawa-san too much trouble?" Fumino asked worriedly.
She was of course very happy that Ren could help them ask targeted questions, but when she thought about the time it would take to do so, she couldn't help but worry about Ren.
"No problem, the question is very simple," Ren answered honestly.
Maybe for other people it is very difficult and takes a long time to prepare, but for him, a person who has superpowers, it is just a thought.
He even said that these seven after-school exercises were all made by him, and they were just a cover when they were taken out of the school bag.
"Okay."
Now that he said that, Fumino couldn't say anything, but she just clenched the hand holding the test paper tighter.
Glancing at Itsuki and Fumino, Ren estimated the time needed to complete the math questions based on the speed of the two of them, and introduced: "This set of questions can usually be completed in half an hour. If it takes longer, it takes an hour."
"If you hurry..."
After saying this, Ren glanced at Rizu, then continued: "Five minutes."
For Rizu, a genius in science, those five minutes included the time she spent writing down the steps.
"It won't take five minutes."
Rizu saw the question and corrected it.
These are just some basic questions that can be solved easily.
"Then I'll try to finish it in half an hour," Fumino said with a smile.
Even though her math scores had improved a lot compared to before, when faced with the questions asked by Ren, she still set a fairly conservative pace.
Itsuki agreed: "Like Furuhashi-san, I'll try to see if I can finish it in half an hour."
"Okay, give it to me after you finish it tomorrow afternoon, and I will help you fix it."
Seeing how cooperative they were, Ren added and started packing his things.
Now that the tutoring is over, it's time to go.
Fumino and Rizu packed their things and prepared to leave with him.
"Do you have to hand it in tomorrow afternoon?"
At this time, Nino suddenly asked.
In an instant, everyone's eyes fell on her.
Ren answered softly: "Yes."
"Can I do it the day after tomorrow? I might not be able to finish it today."
After thinking about what to do tonight, Nino asked tentatively.
"Okay, but tomorrow there will also be practice questions."
Ren didn't reject Nino's idea of delaying his submission, but just reminded her that he would also hand out practice questions tomorrow.
Whether she does the exercises or not is his business, and he has no control over her.
"Tomorrow's exam is due Monday, okay? I remember weekends are not the time for tutoring."
Nino still knows that tutoring hours are Monday to Friday afternoons, and weekends are free time.
"Can."
After agreeing and making sure there was nothing anyone else wanted to say, Ren, Fumino and Rizu walked towards the door together.
Seeing this, Itsuki hurriedly got up and saw them leaving the house.
After seeing off Ren and the others, Itsuki closed the door and returned to the living room.
"I was shocked just now. I almost thought Nino would get into a fight with Kamikawa-san."
Thinking about the incident that just happened, Itsuki said with some fear.
As a sister, she knew very well that Nino had a very strong nature.
But Ren calmly decides what to do next, and Nino herself does not like studying.
It's not impossible to refuse to do practice questions and even fight with Ren.
"I felt the same way earlier," Ichika agreed.
Yotsuba added with a smile: "Yeah, I was wondering who I would help if you guys got into a fight."
"Hey, do I have that kind of image in your mind?"
Hearing her sister, Nino laughed angrily at them.
"How can I argue with him just because of practice? I had something to do tonight and was worried about not being able to finish it, so I asked that question."
In the past, she might have been angry because of this matter, but now that she had promised Naoki to study hard, how could she possibly quarrel with Ren, who had come to help them with tutoring?
After all, she was looking forward to the gift he had prepared for her.
"And you, Yotsuba!" Nino turned around and looked over, then pinched her face, "I quarreled with him, and you still doubt who to help. Then you shouldn't help. Are you 100% helping me?"
"I was just... Just talking casually," Yotsuba said incoherently as her face was pinched.
Seeing Yotsuba treated like this, Itsuki subconsciously touched her face.
Luckily, she didn't say that she planned to side with Ren.
