After becoming a chaotic daughter

【Set point N(3, m), straight line l: y=k(x-3)+m, simultaneous equations...】

Sitting at the chaotic desk, Nanako was lying on the table, slowly writing formulas on the draft paper with the pen in her hand, and a book of "High School Mathematics Special Topic Practice" under her arm, the tone There are densely printed exercises on the single boring page, and Nanako patiently worked on it one by one.

She finished five questions very "patiently", then dropped the pen, pushed away the exercise book, and reached out to pick up the novel magazine on the other side of the desk, opened the magazine and began to read the novel stories on it .

"Nanako——" Ranbu, who was sitting on the office chair, was holding a manga, and while reading the manga, he threw another potato chip into his mouth without raising his head, and crunched it into pieces, "Go downstairs and help Dad Buy cakes!"

Randomly took out a 500 yen coin from his pocket, ranpo gave the coin to Nanako, and sent her to run errands for him.

Nanako picked up the coin that had been thrown on the table, holding the round coin in her palm.She raised her head and looked left and right. Gogol was sitting at an empty desk, supporting her head to help her copy today's homework. The thought of "I don't want to copy words" overwhelmed the thought of "I'm too lazy to move my butt and run errands". After thinking about it for a second, Nanako decided to run errands for her father to buy cakes by herself.

She stood up, thought for a while, and felt that she was "sharing the labor of the other party for Guo Guoli".Therefore, adhering to the principle of "fair exchange", Nanako sat back on the chair, rummaged through her schoolbag, and pulled out the Chinese copybook and Chinese textbook.

She silently stood up with the two booklets in her arms, moved them to Gogol's desk like a little snail, then silently put down the copybook and textbooks, and slipped silently. Out of the detective agency.

After closing the door of the detective agency, Nanako immediately trotted into the elevator and pressed the [1] button.

The elevator stopped on the first floor, and when passing the mailboxes at the entrance and exit of the office building, Nanako saw that the row of mailboxes in the detective agency was full of letters, and some of them couldn't even fit in. envelope corner.

Nanako carefully grabbed the corner of an envelope and pulled the letter out of the delivery slot.The white envelope has been crumpled. The sender is the chairman of "So-and-so Medical Devices Co., Ltd.", and the addressee has the name of the president written on it. What is inside the envelope is some kind of stiff paper, Nanako Guess it was an invitation to a business dinner or something.

Detective agencies have been in the limelight recently, and many agencies have sent similar invitations, some of which can be rejected, but others cannot.

The president's grandfather was forced to change into formal clothes, and went to several meetings on such occasions. When he came back every day, he looked as if he had fought a life-and-death struggle with a hundred killers. Ranpo and Nanako said that the president is "" Surrounded by troubles, so the heart is like still water", which is also commonly known as "people are numb".

It is better to be invited to a banquet than to be a guest, at least for Nanako who stays at the detective agency every day. After all, the former is none of her business. Every now and then, someone I don't know will pick her up and say something in a very exaggerated tone, "As expected of Mr. Ranpo's daughter", "It's extraordinary at first sight", "It's quite like Mr. Fukuzawa"-and so on. Eyes talking nonsense.

As the saying goes, a dead fellow Taoist will never die a poor monk.

Nanako stuffed the envelope she pulled out of her hand back into the mailbox, and poked the exposed corner of the envelope very intimately to prevent any letter from accidentally falling out.

The crisp sound of wind chimes hitting, the mellow aroma of coffee lingering in the brightly lit retro coffee shop, the melodious jazz music echoing softly, the red-haired girl with braids wearing an apron subconsciously raised her head and raised her voice towards the people who entered the shop. Customers say hello.

"welcome--"

Putting the orange juice on the tray on a customer's table, Lucy Maud Montgomery turned her head and saw Nanako coming in through the gap opened by the glass door. After leaving the group, she was also in the Vortex Cafe After working for a few months, I am quite familiar with the kid from the detective agency upstairs.

Holding the tray in one hand, Lucy watched Nanako walk into the store slowly, and when Nanako came to her side, she led her towards the bar and asked, "Here again. Does your father pack cake?"

"Yeah." Nanako nodded.

"What an unreliable father." Lucy said in a dissatisfied tone, but she still climbed up to the high chair in front of the bar and sat down, then went into the back kitchen with the order list and went to serve Nanako, she packed the strawberry cake.

Today is a working day. At this time, there are not too many customers in the store. The store manager is standing behind the bar and wiping his precious coffee cups. The waiter is probably busy in the back kitchen. A new young clerk got off and was serving several tables of customers.

The young clerk has strange and beautiful long hair. As long as he is in the space where he is, everyone's eyes will unconsciously fall on him and his long hair.Half of it is pure white like snow, and the other half is rare pink and purple, which are just neatly separated from the middle, so it doesn't look messy, and it is as soft as silk spun from silk.

Such elegant and magnificent long hair, paired with his equally beautiful and moving face, will probably immediately become the focus of the crowd wherever he goes.

Nanako had seen this person before, two or three times on the street, because of his special hair color, Nanako, who was very bad at recognizing people, remembered his appearance.

The young man's name is "Sigma", a name full of "mathematical flavor", and he came to the whirlpool coffee shop as a waiter three days ago.He has a good temper. Nanako only talked to him a few words and thought he was a good person.

Nanako heard from Gogol that Sigma seemed to be an international student studying in Japan. His family owned a casino in Russia, but because the casino closed down and the family went bankrupt, he had no money to continue studying, so he had to work in a coffee shop first, and wait until he saved enough money. After paying the tuition fee, he went back to school to continue his studies.

Some people are still trying to save money to study even though their family is bankrupt.

Some people, at the age of 16, have not even been to school.

Nanako thinks that more homework should be used in the future, so that Gogol, who is out of school, can feel the "warmth" of school.

There were not many guests, and Sigma soon became free. Nanako watched him sit down at a single table in the corner. There was a pen and two books on the table.Sigma put down the tray in his hand, picked up the pen, opened the two "books" on the table, looked at them for a few seconds, and soon began to write something.

Nanako looked at the two "books" he spread out on the table, one was thicker and the other thinner. Although they were a little far away and couldn't see clearly, Nanako still felt a little familiar.

... For some reason, she always felt that those two "books" looked a bit like her English textbook and word copybook.

that thickness.

that size.

And the book cover of that bag.

Japan is a country that likes to cover books. Not only students will cover newly issued textbooks, but when adults go to bookstores to buy books, many bookstores will also provide free book cover services. Put the plastic or kraft paper cover with the bookstore logo on the customer's new school bag.

Nanako also wraps her textbooks with book covers. Her English textbooks are wrapped in white-bottomed book covers with little yellow ducks printed on them. It is the "little yellow duck book cover set" that Luanbu found after squatting in the stationery store for 5 minutes. ".

——But her English textbooks and transcripts should be in the detective agency at this time.

When she went out, Gogol was still slowly helping her with her homework of copying words... Although she didn't pay attention to see where Gogol copied.

Sitting on the high chair, Nanako clasped the bar with both hands, and looked at the position in the corner with her head. The body sitting on the chair was dangling, and the small leather shoes on her feet stepped on the pedals of the chair.But no matter how she stretched her neck, she couldn't see what was written in the book so far away.

[Slip over and take a peek. 】

As soon as this idea came to Nanako's mind, Lucy lifted the curtain and came out with the packed cake.

"Here, your cake." With one hand on her hip, she handed the cake box in front of Nanako with one hand, holding a small bag of cookies wrapped in a plastic bag, only two or three pieces, Watching Nanako carefully jump down from the high chair and take over the cake box, she handed the plastic bag containing the cookies to Nanako, "This is from the store manager's aunt, hurry up and thank you Take it!"

The auntie of the store manager is the auntie of the waiter, and the auntie of the waiter and the store manager who make coffee are husband and wife, so it is not wrong to call her "Auntie the store manager".

Nanako also caught the cookie, looked at Lucy with dark eyes, and said firmly, "Thank you."

"Okay, okay, go back quickly!"

Lucy waved her hand, pushing Nanako out like she was chasing a duckling. Although it was a gesture of chasing someone, she pushed Nanako's shoulder lightly. She also helped Nanako open the heavy glass door and looked at her. Xiaotiao went down the steps in front of the shop, and then closed the glass door behind Nanako.

Nanako was carrying the cake box, nibbled on the cookies, and wondered whether Sigma was copying the same English textbook as hers. When she walked into the office building, she saw someone waiting for the elevator. .

She was a woman with long black hair, fluffy and slightly curly. She was wearing an off-white long windbreaker and a small square bag with a simple style on her shoulder. She couldn't tell her age from her back.

It may be someone from the law firm on the third floor, or a client from a visiting law firm or a detective agency.The elevator door opened slowly, watching the woman walk into the elevator, Nanako bit the cookie, and quickly ran over with the cake box, and ran into the elevator car before the elevator door closed.

After she stood firmly, she turned around and stretched out her hand to press the button with the number [4] written beside the elevator door. After she withdrew her hand, the woman standing beside her didn't reach out to press other floors.

That should be the client who came to the detective agency to entrust.

Nanako thought about it in her heart.

She stuffed the remaining half of the cookie into her mouth, her cheeks puffed up a bit, and as she chewed, she moved like a little hamster just eating.

Nanako raised her small face, and turned her head to take a look at the client reserve who is about to send business to the detective agency. It would be best if she could assign this job to Ranpo, and don't let her idiot father Continue to fish.She has gone back to school to continue her studies. As a father, Luanbu should of course 'share joys and sorrows'.

Thinking so, Nanako raised her head and saw the woman's ordinary face, which could only be regarded as delicate.

It is a face that is not easy to impress people. It looks like it is in its early 30s. It is very ordinary, just like every ordinary person passing by on the street. There is nothing special about it. It only has a pair of eyes. Some rare deep black, very deep, completely pure black, like thick ink falling from the tip of a pen.

The woman stared at the closed elevator door in front of her, but within two seconds, she soon lowered her eyelids again, and suddenly noticed Nanako who was staring at her from the corner of her eye.

She turned her head slightly, met Nanako's gaze, and opened her mouth, as if she wanted to say a few words to Nanako, but in the end she just smiled gently at Nanako.

Nanako couldn't see any emotion on her face, she stared at the aunt without turning her dark eyes.

With a clear sound of "ding", the elevator reached the fourth floor.

Nanako looked back, she lowered her head, clutching the cake box tightly in her hand, there was still the last piece of cookie in the bag, she didn't eat it, but just held it in her hand, sweet and crispy cookie Cracked into pieces.

Nanako ran out of the elevator, opened the door of the detective agency, got in through the crack of the door, turned around, and locked the door.

That aunt has eyes very similar to hers.

She didn't want that aunt in.
