"You are..."
"Sorry for the late introduction. My name is Kamiki Eiji, I'm a part-time worker here."
"Oh, so you're the young man Nino was talking about! My name is Nakano Itsuki, just call me Itsuki so you don't have trouble distinguishing our names."
Glancing at Nino across the table, Itsuki felt Eiji looked even more handsome than the photo sent in the group chat.
"So, Kamiki-kun, can you show me where I made a mistake."
Not only was she not angry, she gave Eiji a chance to verify her statement.
Although Itsuki was only a trainee teacher who had been teaching for three months at one of the high schools in Tokyo, she was highly dedicated to her work. For example, when she corrected students' math test papers, she would provide the correct answer to the wrong answers so that the students could study them at home.
"Sure, give me a pen and paper."
"Use this."
Taking a notebook and pen from her bag, Itsuki handed it to him.
"The formula in this part is wrong." Eiji said, pointing to one part of the test paper.
He carefully observed the formula Itsuki had written, then continued, "If you use the correct approach, it should be like this..."
Eiji began to write a new formula smoothly, confidently showing the correct steps.
"..."
Itsuki could only be stunned watching his explanation, which was so detailed and reasonable.
How could a young man who had lost his memory be so brilliant in mathematics? His explanation was easier to understand than when Fuutarou taught the five of them when he was still a tutor!
Nino wasn't lying to her, was she?
"Oh my god, I didn't even realize. I almost misled the students."
After carefully examining the formula Eiji had written, Itsuki admitted her mistake without making any excuses like politicians.
"It's not just that, Itsuki-san made some other minor mistakes."
The pen in his hand moved quickly, Eiji corrected the formula Itsuki had written and marked the location of her mistakes.
"There are many? Maybe I'm not suitable to be a teacher..."
The ahoge hair on top of her head wilted, Itsuki doubted her own qualifications.
"Itsuki..."
Seeing her gloomy, Nino and Miku wanted to cheer her up, but before either of them could start, someone acted faster.
"It's okay, Itsuki-san. Everyone can make mistakes, you don't need to be ashamed. The most important thing is how not to repeat the same mistake." Eiji was like an experienced mentor.
"Kamiki-kun is right, this shouldn't happen again, I'll be more careful from now on so I don't make the same mistake."
Itsuki's face turned slightly red with embarrassment, but she immediately nodded earnestly.
"Thank you very much, Kamiki-kun. You helped me a lot. As a thank you, I'll take you to my favorite place to eat."
"No need, Itsuki-san said herself that a teacher's job is very busy. I don't want to bother you."
"No, I have time on the weekend. Let's go together."
"That—"
Before Eiji could continue his refusal, Nino interrupted their conversation with an unhappy tone.
"I didn't expect Itsuki to be so active in asking men out on dates. This is unexpected, you think so too, right, Miku?"
"Mm."
Miku just nodded, not wanting to get involved in the confrontation.
"D-Date?! W-What are you talking about Nino? I just want to return the favor to Kamiki-kun."
Standing up and tapping the table, Itsuki refuted with a blush on her face. She didn't want to be misunderstood as liking the young man.
"It's just a joke, don't take it too seriously, Itsuki."
Nino changed her initial frowning expression to a playful smile on her face.
As the saying goes, women change their expressions faster than turning the pages of a book.
"Huft... That's not funny at all, Nino." Itsuki sighed, then she looked at Eiji and asked curiously, "How did Kamiki-kun know the formula I used was wrong just by looking at it once?"
"I don't know either. It just happened, when I saw the test paper, I felt it didn't matter if the test was difficult."
Saying that, Eiji scanned the test paper on the table. He was sure he could get a perfect score if he took the test himself.
"Let me tell you something interesting, Itsuki. Actually, Kamiki has an IQ of 210!" Nino smiled proudly as if it was her achievement.
"IQ 210?!"
Hearing that, Itsuki was shocked and exclaimed. After all, she and her four quintuplet sisters had below-average Iqs and barely graduated from high school. Therefore, her reaction was huge.
"Miku and I also showed a similar response to yours." Nino chuckled.
"Itsuki is so cute." Miku smiled amusedly.
Eiji: "😐"
Because Itsuki kept talking, he didn't want to interrupt and could only wait for the atmosphere to calm down.
"Amazing... Doesn't that mean Kamiki-kun is smarter than Uesugi-kun? If only he was our tutor." Itsuki sighed regretfully.
"You're thinking too much, Itsuki. When we were still in high school, Kamiki-kun was only 13 years old. Dad would never agree to let an elementary school student teach us, no matter how genius Kamiki-kun is." Miku rolled her eyes and couldn't speak.
"That's true." Itsuki felt embarrassed by her silly idea.
"..."
Seeing that they had finished chatting, Eiji no longer delayed.
"Nino-san, Miku-san, since it's closing time, can I go out for a walk? Don't worry, I won't go far so I don't get lost."
"Sure, but you have to be back before 8:30 pm."
"Understood."
After getting permission from Nino, Eiji immediately left the restaurant.
"Are you sure Kamiki-kun will be alright?" Miku asked, still worried.
"Kamiki is not a child. Besides, can't he use his phone if he really gets lost? Let him get to know the surroundings."
"So that's it."
Itsuki didn't interfere with Miku and Nino's conversation, she continued her task of correcting the test papers. This time, she was more careful.
❀❀❀
Meanwhile, Eiji had walked a few hundred meters from the restaurant.
"Winter is coming."
On the street, the majority of pedestrians wore thick clothes that provided warmth to their bodies.
"It seems my body has a resistance to cold temperatures that exceeds ordinary people."
Eiji was not affected by the cold wind at night. He discovered a new fact about himself.
Occasionally, some women approached him to invite him to karaoke or play together. Having no money, he declined all their invitations.
"Hm? What are they doing?"
At a crowded zebra crossing, Eiji saw a black man dancing in the middle of the road, disturbing other pedestrians.
There was another black man recording the dancing man's actions with his phone.
With his Six Eyes vision, Eiji saw the other party's phone screen while running a live broadcast application.
"So that's it. Foreign tourists who are causing trouble in Japan to collect donations and AdSense from their actions that attract viewers."
Taking his gaze away, Eiji lost interest in them. He continued his wandering and saw many things in Tokyo at night.
