Chapter 29 Cheating

Maki came out of the bathroom drinking milk as usual. If it were someone else, they would drink beer in the basin on this occasion, but Maki was born allergic to alcohol. "I said, look at this..." As if waiting for Maki to drink milk, his wife Masako put a piece of paper on the table, "Look at Ryozo's exam paper?" "Huh? 100 points..." Maki couldn't help but took the piece of paper and looked at it carefully. There were mathematical formulas on it, all of which were two-digit multiplication two-digit math problems. There were about 50 problems. All are circled in red.

"The answers were quick, and they were all correct!" There is also a line of comments in red letters like this above. "Well, great! Is that guy asleep?" If he hasn't slept yet, Zhenmu really wants to praise him a few words. "I've been asleep for an hour. Not only did he answer these questions well, but he also answered the other questions well. He was the first to hand in the test paper, and he got all the answers right. It seems that it's right to invite Teacher Lily Zhi!" A month ago, Liang Ze had been studying with a female high school student named Lily Koizumi.Masako and Liangze both called this tutor "Lily Branch".

Yurie Koizumi is the niece of a beautician Masako knew. Once, when Masako was doing her hair, the beautician asked: "Are the children in your family primary school students? Do you go to a private school for homework?" "Oh, my husband said that elementary school students don't need to go to tutoring. I don't agree with that either." "Then you can hire a tutor! My sister's daughter is in the second grade of high school. She wants to be a teacher after graduation, so she wants to work part-time to tutor elementary school students." It seemed that the topic was going on like this at the time.

Maki went to China on a business trip.A week after returning home, Masako told him about it. Masako's sentence "Please invite Mr. Lilyeda to come" - it was at Masako's insistence that Maki agreed. "But it's a bit weird!" Shinaki asked while looking at Ryono's answer. "What's wrong?" "Answer! Generally, the multiplication of two digits should be written in the calculation formula, but he only wrote the answer." "yes." Masako pouted.This is her habitual action. "As you said, the multiplication of two-digit numbers is a written calculation, right? That's the calculation method for third-grade students when they graduate. And in fourth and fifth grade, they use computers or abacus to calculate. Therefore, mental arithmetic can calculate the number... "

"Oh, so Liang Ze already used a calculator?" "Well, his calculator and abacus are useless. He said he used a silent algorithm." "Silent calculation? Is it cheating?" Maki asked. "No. He said it was a method taught by Teacher Lily Zhi." "Wait a minute. What does the word 'mo' mean? Is it a new way of cheating?" "No, how do you teach children this kind of thing? I'm afraid it's a new calculation method. I remember it was introduced on TV." "But what is 'silent calculation'?" So, Maki took down the tome dictionary "Kōjien" from the bookshelf in the corner of the living room.

He didn't find the word from the word "mo".I have been looking up the last word of this group of pinyin, but I can't find an explanation for "silent calculation". "How is it? Did you find it?" Masako also asked, looking at the dictionary. "No. Some popular slang, I'm afraid." "What? How about calling Liang Ze up and asking?" "Forget it, don't call him." Maki closed "Guangciyuan". In the afternoon of the second day, Maki thought of the word "silent calculation" again.That's when he heard the term while eating deep-fried shrimp at a soba restaurant near his company.

A joke show was playing on the TV in the store. I don't know who the actor was, but it seemed that he said the word "silent calculation".Just such a word suddenly triggered the memory of this word stored in Maki's brain. Ah, maybe this is a popular word in the film and television industry.Maki was thinking this while munching on the fried shrimp. As soon as he got back to the company, he went into the library.I went straight to the dictionary shelf, where there were several Mandarin dictionaries. He searched one by one, and finally found that there were two dictionaries with the word "silent calculation".

[Silent Calculation] Using computer games or application programs to obtain effective results using undisclosed operating methods. (Sanseido's "Great Ci Lin") [Silent Calculation] Use computer games and other methods that have not yet been formally operated to carry out favorable development. (San Seido's "Xinming Jie Guoyu Dictionary") From here, it seems that it is a computer game language.For Maki, he is "computer illiterate", so it's not surprising that he doesn't know at all. Masako also doesn't know much about computer games.Although she explained that "silent calculation" was a "special method", she also didn't understand what that meant.

Therefore, Maki became more interested in the term "silent calculation". One day, Maki called home beforehand and returned home much earlier than usual.Because if you don't tell the family first, the wife won't prepare his meal. He wanted to finish the housework earlier so that he could ask Liang Ze what "silent calculation" meant. After Maki returned home, she changed her clothes in the bedroom when Masako came in. "It's also good news today, he was praised again..." As she spoke, she showed Zhenmu the homework. "Yesterday, Liang Ze's arithmetic score was the highest in the class. Not only did he score in arithmetic, but he is also interested in learning. I am so happy."

The seal of "Obana" is stamped under the homework. "What is this?" Shinaki asked while returning the homework to Masako. "This is a connection book between school and family. So far, it is full of praise and comments. Therefore, this child also loves going to school." "What about this 'Oka'?" "It's his homeroom teacher." Masako was stunned, "It's Mrs. Taeko Obana!" "Oh? Isn't the head teacher calling for a meal?" "No wow..." Masako frowned and said, "He is the former teacher. After five years as the class teacher, he changed to Teacher Ohana. Anyway, she always praises good rules."

"Well, that's not bad..." Shinaki said while changing his clothes, "Why did he suddenly fall in love with school?" "Thanks to Teacher Lilyzhi! He is an only child, and he doesn't even have a talking partner after he comes back from school. How boring! When Teacher Lilyzhi comes, isn't it like having a sister? Every Wednesday when the teacher comes And Friday, he was as excited as if he had lost his soul. And he hoped to be praised by Lily Branch, so he studied hard." "Ah? He's not in love, is he?" Maki said and laughed.When he was in the fifth and sixth grades of elementary school, he had a crush on female middle school students. "Really..." Masako also laughed, "Ms. Lilyzhi is a high school student, so it's not polite to say that!" Dinner is roast beef with vegetables. Maki usually only comes back once or twice a week early, and at that time, this dish is cooked at home. Masako thinks it is best to cook this dish when the whole family is together. "Ah, let's get this one!" Shinaki picked up a large piece of beef and put it on his son's plate. "Ah, thank you." After hearing this sentence, Maki stared at Liang Ze's face, as if he had never seen his son like this. Liang Ze showed his white teeth and smiled happily. He has changed, and he must have been influenced by "Teacher Lily Branch"... "Then..." Sanmu suddenly said, "Liangze, do you know the word 'silent calculation'?" "What, what 'silent calculation'?" Liang Ze asked strangely. "It's arithmetic! The 'silent calculation' method used when doing calculations." "What..." Liang Ze looked at Masako with a puzzled expression, "Mom, what did you say?" "Do not be like that!" "Why don't you..." "You really don't want to do this!" Shinaki said, "Your mother knows about it, but your father doesn't. It's not fair!" "This……" "What kind of technique is this 'silent calculation'? Teach me?" "No!" Liang Ze unexpectedly refused.And with a strong tone. "No? Why?" "That's silent calculation. Silent calculation cannot be taught." "That's weird." Shinaki said, "Didn't your tutor teach you?" He can't call "Teacher Lily Zhi" like Masako and Liang Ze.Maybe it was because of the consciousness that she was only a sophomore in high school. "Ms. Baihezhi thought of that silent method. She created it herself, and no one taught this method. Because I didn't invent it, what I said without asking the teacher..." "Ah, then ask!" Shinaki said with some admiration, "I don't know if she agrees, but this is considered a rule." "Ah, there must be rules..." Shinaki tilted his head and thought for a while: Ryoze's words are also correct. "And..." Liang Ze went on, "I said 'silent calculation' to my mother, but I never said what 'silent calculation' is, so it's not unfair to not tell my father, right?" "Ah, that's true. But seriously, your dad was really surprised when he saw your homework. So you really have a calculation method faster than computers and abacus?" "Hmm..." Maki paid close attention to Ryanori's answer.But it wasn't a confident "hmm," and he felt his son was a little confused. "Then, after dinner, you can do it in front of your father, so that he can see it too." "What do you know?" Liang Ze's expression became stiff. "It's a two-digit calculation! Let your father come up with a question..." "That can't be done. 'Silent calculation' is not a juggling show for people to watch." Liang Ze waved his chopsticks with his right hand.His face became red. "you……" Masako gestured to him with her eyes, as if she wanted to continue asking. "Understood." Shinaki said helplessly, "Forget it. I'll ask 'Teacher Baihezhi' again. If she knows that a father wants to know what 'silent calculation' is, she will definitely tell me..." "Hmm..." Liang Ze also nodded helplessly. The next day, Maki went to the company with the arithmetic problems that Liang Ze brought home. There are college students who graduated from science and engineering in the company.He thinks that these people will understand what's going on when they look at the arithmetic problems of Liang Ze. In order to take away the assignment, he also had a fight with Masako. She said she didn't understand why her husband insisted on finding out what "silent calculation" was. "What I mean is that if this 'silent calculation' is a means of cheating, it will be very detrimental to the future of Liangze. And it is even more serious to teach elementary school students to cheat. In this way, we cannot let such people be tutor." "But will you know if it's cheating when you get it to the company? Does your company have cheating experts..." "No. In the company...for example, Koga-kun, he graduated from the mathematics department of the university. So, let Koga-kun see the answer and he will understand what is going on with the 'silent calculation'. If even he If you can't see it, it means that this is a cheating method. If this is the case, I will quit this tutor..." "It's ridiculous!" Masako shouted loudly, "That Mr. Koga is not a god, so he may not be able to understand it. His judgment is not absolutely correct!" "Although it's not absolutely correct..." "How about this?" Masako came up with a compromise, "If Mr. Koga doesn't understand, you can just ask Teacher Lilyzhi directly, and if she doesn't understand, then she will be dismissed." "Well, you are really smart!" Maki agreed with Masako's suggestion. As soon as he arrived at the company, he immediately made a copy of the question paper and answers of the good rules. There are thirty questions in total.At first glance, I thought it was more than fifty, but it was actually an illusion. Then he took this copy and went to other departments to find Koga. Koga joined the company two years later than Maki.He had learned that Koga graduated from the mathematics department of the university when he made the company's operation plan. When Maki patted his shoulder from behind, Koga immediately turned his head. "Ah, it's rare!" He laughed, "Is there something wrong?" "Oh, I brought something to ask you, a great expert, I'm laughing at you." Saying that, Shinaki put the copy on Koga's desk. "Is this all calculated?" Gu He looked at the copy and said. "Hmm. However, I wonder if this method of calculation is a kind of 'silent calculation' that is faster than computer or abacus calculations." "'Silent calculation'? Ah, I see, it's faster than using a computer to calculate the answer." As Koga spoke, he wrote in pencil on the copy: 24×26=624 72×78=5616 93×97=9021 ... Maki can understand at a glance. Koga's pencils are flying around, non-stop.Maybe Koga is using "silent calculation", but outsiders can't see it.His speed is exactly like printing out with a printer. "yes……" After Koga finished writing, he pushed the copy in front of Maki.It was only a minute before and after. "It's incredible!" Maki said in surprise, "As expected of an expert in mathematics! Is this 'silent calculation'?" "Yes, this is a kind of 'silent calculation'. Mathematics has nothing to do with 'silent calculation'. But there is a rule in these questions, and it is easy to understand..." "law?" Maki's eyes fell on the copy that Koga pushed back. "How?" Koga asked, "Do you understand its law?" "No, sorry, I..." "Then let me explain, please sit down..." Koga said and let Maki sit on an empty chair next to him. "Well, the first question is 24×26. Its 4 and 6, what do you think?" "4 and 6? Ah, if there is 5, it can be connected into 4, 5, 6." "Not bad..." Koga said while stroking his chin, "That is to say, 2 and 8 in the second question, and 3 and 7 in the third question... After reading these, do you think there is any pattern in it? ?” "This..." Zhenmu was puzzled, "The single digits of the first question are 4 and 6, the second question is 2 and 8, and the third question is 3 and 7... the combination of these three numbers is 10 .” "Yes, that's correct." Koga nodded with satisfaction, "This kind of relationship is called the relationship of 'complementary numbers'. These problems are the formulas in which the ones digit of all multiplications is a complementary relationship." "So what?" Maki looked at the copy again, and it was indeed what he observed. "How about it?" "That's the case. But Mr. Koga, is this very clear without looking at it?" Shinaki asked puzzled by this point. "Oh, it's like this... I like numbers more for mathematics. When I see the license plate numbers of cars walking on the street, I think how much they add up. This is my hobby..." "So, what if the numbers in the ones place add up to 10?" asked Maki. "Oh, the formula written here is another law. I think it's very simple." "Well, let's put it this way. For example, if the multiplied single digits add up to 10, the same number..." Maki said boldly. "Yes, as you said, the addition of single digits in the formula here is all 10. How about it? Because this is multiplication, two-digit multiplication is two numbers, which are the same when compared with 10. And the individual The digits of the digits have a complementary relationship." Koga took "24×26" as an example. "It's a two-digit multiplication. The product of the single digits is 24 when they are multiplied." "And this time it's a 10-digit calculation. On the one hand, the 10-digit number is 1. They are multiplied together. Therefore, in this formula, it is 2+1=3 and then multiplied by 2. That is, 2×3=6." As he spoke, Koga wrote "6" before the "24" he wrote just now. "This 624 is the answer to 24×26. The same is true for the following, and the answer can be easily obtained by using the same method. Of course, this method is faster than computers and abacus." "Hmm... the sum of the ones digit is 10, and if the 10 digits are the same... this kind of calculation method can be used for multiplication." "Yes, we still need to prove that its laws are correct." Gu He said while smiling. "Can you prove it?" "The laws of the digital world can be proven. Come and see." Koga turned over the copy that Maki had brought, and wrote on the back: [10A+B] [10A+(10-B)] =100A2+100A-10AB+10AB+10B-B2 =100A2+100A+10B-B2 =100A(A+1)+B(10-B) "It should be like this. If the formula of 24×26, A is 2, B is 4, the final formula is to bring A and B into the formula. Try it." 100×2 (2+1)+4 (10-4) "The important thing is to put the multiplication of 2 and 3 equal to 6 in the position of 100. In this way, in the case of 1 and 10, just multiply 4 and 6 and write it." "Ah, now I understand... I will think about it slowly in the future. Ah, thank you very much." After finishing speaking, Maki stood up from the chair. "It's a call from your house." When the operator said, Sanmu was slightly startled: Could it be that Liang Ze had a traffic accident... If it wasn't urgent, Masako wouldn't call the company. "yes……" "Excuse me, are you busy now?" Masako asked eagerly. "Ah, it's okay, what happened?" Maki asked immediately. "It's not something urgent, it's a matter of 'silent calculation'... What did Mr. Koga say?" "this……" Maki felt a little strange.Does she also care about Koga's answer?But for this, she will call... "It's still a matter of 'silent calculation'. I was surprised when I calculated it myself." After listening to the "lesson" from Koga, Maki also recalculated those questions. He used the method that Koga taught, and the time was 90% faster than normal. "Well... do you think it's necessary to ask Teacher Lilyzhi face to face?" From Masako's tone, Maki noticed that Masako suddenly became very calm. "Well, but..." "Today is Wednesday, and it's also the day when Teacher Lily Zhi came. If you can go home early, I think you will see her..." "Early? What time is it?" Maki asked. "Usually she comes at 3 o'clock and goes back around 6 o'clock. So, you can arrive before 6 o'clock..." "I can't go back at 6 o'clock today. However, I can think of a way, what's the matter?" Shinaki asked. It seems that Masako really wanted to meet Maki and Yurie Koizumi. "Today, a gift for the Ghost Festival was sent from Teacher Lilyzhi's house. And her father wrote a letter..." "Gifts for the Hungry Ghost Festival...but we are the ones who should give gifts..." "Yeah, I feel very embarrassed. It's just that the letter is a bit strange. It's something like 'I'm very sorry, I often eat at your house and stay overnight. I'm very sorry...'" "Stay overnight?" Shinaki asked, maybe Lily Koizumi stayed at home when he was on a business trip? "No! She hasn't even eaten dinner. Every day I prepare food for her, but she never eats and goes home." "So, her family has always thought that she lives in the home of a student who is a tutor?" "You can only think so? So, come back quickly and ask about this." "But if you want to ask this, why don't you just ask? It's not too much for you to ask such a letter from her father." "It's true..." Masako seemed a little embarrassed, "During the time the teacher came, Liang Ze never left us, asking such complicated things in front of him..." "Yeah..." Zhenmu smiled wryly, "Will Liang Ze not leave? It seems that he really likes her." "That's right. Last night you said Liang was your first love, and I really felt that too. He still respects her a lot." "What kind of person is she?" Maki asked. "What's it like... It's different from the female high school students seen on TV. She doesn't wear makeup or white line half-height pantyhose, which is fashionable for female students. She has short hair and looks like a boy. She moves like a girl. He looks like a child, but he can't say a word anyway." "She... is a sophomore in high school..." I learned from a weekly magazine that there are many female high school students engaged in prostitution in modern society.Maybe she stayed at a man's house... "Okay..." Maki made up his mind, "I'll be home at 6 o'clock today. So, you must keep her!" "Understood. But work doesn't matter, does it?" "Ah, there are only two things. One of them can be done tomorrow." Maki replied. On this day, Maki finished his work and returned home at 6:10. As soon as he entered the house, he first looked at the place where the shoes were placed.If there is a pair of women's shoes that have not been seen before, it proves that Lily Koizumi has not left. But did not see the shoes he expected. "I'm back..." He said and took off his shoes.But there was no reaction at home. He entered the restaurant, Masako was alone at the table. "Teacher Lily Branch is in Liang Ze's room?" Shinaki asked in a low voice. He only used the word "teacher" when he might be heard by Lily Zhi. "Well, she's resting today... Liang Ze may be very depressed because of this, shutting himself in the room and playing game consoles." "Rest? Did she say so?" "Yes, she didn't come at 3 o'clock in the afternoon. I thought it was very strange. She just called and said that she couldn't come because of a temporary emergency... So I called you immediately, but I said that you were out of business, and then I went directly go home." "yes……" Maki sat down at the table without changing his clothes. Along the way, he planned to ask Koizumi Lilyzhi a few questions, but it was in vain.Ryoze is the same, looking very depressed. "But don't you think it's a little weird?" Masako made a cup of tea for Maki while talking. "Strange? Who?" "Teacher Lily branch!" Masako put the teacup in front of Maki. "If there is something urgent, we have agreed before that! Isn't this a breach of contract?" "How to pay her?" Maki asked after taking a sip of tea. "She comes twice a week, 10,000 yen a month. If that's the case, it's not sure what to do if she doesn't come temporarily." "Twice a week, eight times a month, 10,000 a month, isn't it too cheap?" It is equivalent to 1,250 yen at a time, and if it is calculated as three hours each time, it is equivalent to more than 400 yen per hour. "However, that's what the introducer Yamagata beautician said. And her original intention was to train herself by teaching elementary school students, and she didn't intend to make money..." "Who is that beautician you're talking about?" Maki asked, one of the related questions he'd thought about on the way home. "Thirty-five or six-year-old, quite a cheerful person." "What is Liang Ze's current homeroom teacher like?" "What? Oh, it's Taeko Obana-sensei! She's in her thirties." "Married?" "Ah, it's over. Her husband is a high school teacher." "Where's the child?" Maki asked while drinking tea. "I've never heard of it. What's the matter?" "Oh, let me know." Shinaki only said this, "You said that the beautician is Mr. Lilyzhi's aunt, is that true? Did you talk about the beautician in the chat with Mr. Lilyzhi?" "Ah, I never mentioned it. When I was first introduced by Mr. Yamagata..." "Oh..." Maki stood up, "Let's eat first, I'll go change my clothes." Maki had a question. Liang Ze mastered the method of "silent calculation" from Yurie Koizumi and came up with exam questions suitable for "silent calculation" in the school.And it's not one question or two questions, but thirty questions.However, they are all aimed at "silent calculation". Is it too coincidental?Isn't it easy to feel that the exam questions are made by people who know the "silent calculation" method? As a result, Liang Ze's test scores were the first in the class.The next day, in the contact book, the teacher wrote a comment to praise the good rules. And once you praise the good rules, it is equivalent to praising the tutor... Thinking about it this way, "Teacher Lily Branch" must have something to do with the class teacher Oka... The next morning, as soon as Maki was sitting at the dining table in her pajamas as usual, Masako brought the morning paper.She pointed to a place and whispered: "Keep quiet and take a good look at this passage." "Just don't let Liang Ze hear it?" "Yes, don't talk about it when he wakes up later." Zhenmu took the newspaper strangely. "High School Student Dies Inexplicably in a Hotel" Around 11:00 last night, a suspicious body of a woman was found in a room of a hotel on a bustling street in District S. At around 5 p.m. that day, a man in his thirties and a woman in her twenties entered the hotel, but no guests had checked out after the check-out time.When the room attendant went in to understand the situation, he found that the male guest was no longer there, and the female guest died in the room. The police officers in the jurisdiction investigated the deceased's belongings and found out that the deceased was Miss A Zi (16 years old), a second-year high school student who lived in District M.She told her family to go to tutoring and went out. Department S police are looking for the whereabouts of the missing male. The above is the general content of the message. "Huh..." Shinaki looked at the report in surprise.He understood what Masako was trying to say.The deceased's son-in-law mentioned in the newspaper is most likely Lily Koizumi. Indeed, the fact that she is a sophomore in high school and left home as a private teacher to teach classes proves that she is very likely to be "Teacher Lilyzhi". But if Liang Ze learned of the death of Teacher Lily Zhi, he would definitely be hit.Therefore, Masako repeatedly emphasized not to mention this matter in front of Liang Ze. "Hey, I'm not going to work today, am I?" Maki said. "What? Why?" Masako just brought Liang Ze over. "If it has something to do with this matter, I must come to ask about it. Wouldn't it be better if I was there at that time?" Shinaki intentionally did not say the word "police". "If it's just that..." Masako frowned, "Why don't you visit customers today?" "That's nothing. I just said I had a fever and couldn't move..." Then the phone rang. "I'll pick it up." Shinaki thought it might be the police, so he took off the receiver, "Hello..." "I'm sorry." The other party was a woman, "Is Madam at home?" "Which one are you?" "I'm Yamagata, a beautician." The other party notified the name. "Ah, she is looking at the fire right now, and she can't leave for a while, can you tell me something?" Zhenmu lied. "That's right. Have you read today's morning paper? The student on it is the high school student I introduced. I hope you don't say that I introduced you to your house." "Why? Should we tell the truth to the police?" "Ah. However, the male murderer has turned himself in, right? It won't matter if you don't talk about such a trivial matter." Yamagata explained. "Are you talking about the murderer? Then you know that person?" Maki asked again. "Well... then, I'll call again." Maybe Yamagata thought that what she requested could not be done, so she hung up the phone suddenly. "Who is it?" Masako asked curiously. "It's Ms. Yamagata... She said don't say that the dead high school student was introduced by her." "Huh? Why?" "Ah, she said the male murderer turned himself in." Yamagata wasn't lying.The man who escaped from the dead body of the high school girl surrendered himself to the S Department early in the morning. Maki, who did not go to work at the company that day, learned the news from the noon news. Here's what the news reported— The man was Genichi Ohana (35 years old), a teacher at a municipal middle school in District M with a vocational department. The deceased was a student when he taught middle school.The two got back in touch a year ago. On Wednesday night, he took her to a restaurant in District S.As they had sex and climaxed she made a sudden look of pain, then went quiet. "I wanted to call a doctor, but if I was caught having sex with an underage woman, I could be fired from office, so I ran away from the hotel, but I didn't mean to kill her." He justified it like this. The S Department arrested the man for "violation of juvenile protection regulations" and awaited the results of an autopsy.He will be investigated in detail at that time. "Then he killed someone?" Masako said after watching the news. "Well, there is that kind of game where you strangle the neck during sex to suffocate the other party." Maki continued, "This man is called Ohana, is it Mr. Ohana's husband?" "Maybe. He's a middle school teacher again... Ohana-sensei is so pitiful. Maybe she'll resign..." "Well, yes." Maki said. "But to be honest, isn't it a bit strange? What kind of personality variation does the couple have?" "Ah, this..." Maki's words were a little vague. He was considering whether this incident might have something to do with his wife Taeko Obana.In other words, could the role of his wife Taeko be the cause of the death. First of all, it is a fact that Yurie Koizumi works part-time regardless of the tutor's salary. She also often lied to her family that she was living in a student's home.I'm afraid she lives with Ohana Genichi at the hotel twice a week. In this way, the Yamagata beautician who introduced her part-time job may also have something to do with this incident.Because without her introduction, Koizumi Yurie had no excuse to live outside... The strangest of them all is Taeko Obana.She praised Lily Zhi through the "silent calculation" test questions and contact book.That is to say, her purpose is to make Lilyzhi have more time to do tutoring at the Shinaki family. From this point of view, don't Yamagata beautician and Obana Taeko have a common purpose? And it seems that Taeko Obana doesn't dislike her husband "staying overnight" twice a week. So... Maki reasoned like this. Taeko Obana is most likely gay.Although she is married to Yuan Yi, this marriage cannot "satisfy" her. Later, she met a Yamagata beautician.In the process of many beauty salons, the two sides had "love". And "letting" Yuanyi stay outside is precisely to provide convenience for their sexual intercourse. Maki reasoned like this.And once this reasoning is established, the "silent calculation" test question can be justified. But Maki didn't tell Masako his reasoning because there was no evidence. "Ryoza is too cute, don't hurt him." Maki couldn't bear to let Masako fall into more chaotic conflicts.
