After becoming a chaotic daughter

There are three bookcases in the office area of ​​the Armed Detective Agency.

The largest is a two-meter-high composite bookcase, which houses various documents needed in daily work such as urban maps, contact books, and Japanese traffic timetables;

The shorter one is an oak-white stepped bookcase, which holds various novels, magazines, comic books and game consoles bought at random;

The smallest is a one-meter-high children's bookcase, which houses Nanako and Gogol's elementary school textbooks, writing books, and cartoon picture books.

Every once in a while, the bookcases that have been organized will always become messy due to various reasons. Kunikida tidied up the two bookshelves used by the members for work and leisure as usual, and there is still time to spare, so again Squatting in front of Nanako's children's bookcase, I want to help the two children tidy up their bookcases.

First-grade Chinese textbooks, fairy tale books, children's haiku collections, encyclopedias... He took out the books from the bookshelf one by one, and wanted to rearrange the books and put them back, but when he flipped through them, he felt like he had never seen them before. The titles of the books drawn from the bookshelf seemed to gradually become strange.

"Higher School·Mathematics A", "Basics of Biology", "English Ⅱ" - all his mathematics textbooks in middle school.

"Chinese Elective ([-])" - it seems to be a Chinese textbook, and it is full of classical Chinese.

"College Entrance Examination Must Recite 3500 Words" - the title of the book is also in Chinese, it seems to be some kind of word recitation book.

……

Some of them were his middle school textbooks, which Nanako took from him. During the Longtou War, Nanako seemed to ask him to borrow these books. At that time, the affairs of the detective agency were too busy. Both Nanako and Gogol They were playing by themselves, and the members couldn't spare their minds to take care of the two children.

When Kunikida was asked by Nanako, he didn't pay attention, and just let Nanako take it casually, and he could ask him if he didn't understand.But he didn't pay much attention, after all, Nanako was only a primary school student, so she probably couldn't understand the contents of the book, and could only look at the pictures in the book after getting it.

Of course, he still felt the same way now, he was just a little surprised, what happened to those few Chinese books mixed in the bookshelf.Kunikida Doppo is well aware of the book procurement situation of the detective agency, he has calculated every amount of money in and out, but he doesn't know where these books come from.

He picked up the "Chinese Elective ([-])" among them, got up and wanted to ask Nanako.

Nanako has grown a bit taller, and she is already able to sit at the desk and do homework. Today is the weekend, and Nanako is now lying on the chaotic desk, writing the questions.

Kunikida walked over with the book, pushed his glasses, lowered his head and was about to call Nanako, but suddenly saw the topic Nanako was writing - a high school physics problem to calculate acceleration.

"... Nanako." Kunikida looked at the formula Nanako was scratching and writing on the draft paper, and asked dully, "What are you doing?"

The flickering pencil stopped, and Nanako lay on a pile of draft paper, raised her head, her dark pupils had no light at all, like a deep well without waves.

She looked at Kunikida, and answered him in a wooden tone: "...I'm writing a topic."

No, of course he can see that this is writing a topic.

Kunikida felt that his emotions were very complicated. He felt that he should ask Nanako something, but he couldn't figure out where to start.

Logically speaking, at this time, he should show a look similar to "surprised" and "unbelievable", but there is no fluctuating emotion on Nanako's face, so that Kunikida didn't know how to control his face. muscles, and made such a large expression.

He dryly uttered a few "ah", "oh", and "uh" modal particles, and finally asked: "Have you encountered any problems that you can't do?"

Nanako lowered her head, scratched her hair and thought for a while, then held a pencil, pulled out an exercise book from a pile of messy exercises, opened it and found a question, poked the question with the tip of the pencil, looked up Xiaolian said to Kunikida, "I can't do this."

Kunikida glanced at it subconsciously. It was a physics problem related to the movement of charged particles into an electric field. Although he was already in his senior year, as a self-conscious student who was diligent in enriching himself, he still did not lose the knowledge he had learned in high school.

Therefore, after reading the question, his brain conditioned reflex had already started to think, and he took out a pen and began to explain the question to Nanako: "For this question, first find the electric field strength, and according to the kinetic energy theorem, substitute the initial velocity as 0 case..."

He explained the question to Nanako in a simple way, drew auxiliary lines, and wrote down a few formulas that will be used. He was serious like a teacher who was teaching Nanako a lesson.Finally, he asked in a serious tone, "Do you understand?"

"Yeah." Nanako nodded, picked up the draft paper, grabbed the pencil and began to concentrate on doing the problem again.

Facing such self-conscious students, Kunikida felt very relieved and felt that he was one step closer to becoming an excellent math teacher—he had just obtained his high school teacher qualification certificate last month—he stood up and picked up the The books on the table are as smooth as if the teacher picked up the lesson plan on the desk after class, turned around and prepared to go back to tidy up the bookcase for Nanako, but after taking two steps, he felt something was wrong.

"Nanako." Kunikida finally remembered what he wanted to do, "Did you buy these Chinese books?"

He raised the "Chinese Elective ([-])" in his hand and asked Nanako.

Raising her head from the topic, Nanako saw the familiar book in Kunikida's hand. It was a Chinese textbook that she asked Li Xiaolang to buy for her with pocket money. Hong Kong is also a little troublesome to buy textbooks from the mainland. I bought a few copies and brought them to Nanako after school started.

Nanako felt that Li Xiaolang must be an excellent young pioneer. Not only did she buy books for her during the holidays, but she even went from Tomoeda Town to Shengye Elementary School to deliver the books when school started.

The matter was a bit complicated, so Nanako gave Kunikida an abbreviated answer: "There is a classmate who came from Hong Kong, and he gave it to me."

Although the answer is very brief, it is enough to deal with Kunikida. He seldom asks others to get to the bottom of it. Unless the situation requires it, he always respects the privacy of others, even if the "other" is just a child like Nanako.

After getting the answer, he said "I see", then returned to the bookshelf and continued to help Nanako organize the books.Nanako also continued to immerse herself in writing her own physics problems.

Nanako and Gogol’s children’s bookcases are not big, and Kunikida quickly reorganized them. The various books are sorted by category and color, and the sundries are also sorted and packed in small boxes, and finally placed on the bookcase A small potted plant and a pendulum clock.

Satisfied with the finishing results in front of him, Kunikida stood up and was about to return to his office when he heard the door of the detective agency being opened from the outside.

"excuse me."

The man's flat, slightly hoarse voice came from the gate. Kunikida turned his head and saw a tall man with copper-colored short hair walking into the detective agency. The man was wearing a sand-colored windbreaker and had an unshaven beard. He hadn't taken care of it for a few days. Yes, the appearance gives people the feeling of a slovenly uncle in his thirties.

Kunikida recognized this man.

A low-level member of the port mafia, called Oda Sakunosuke, although he is a mafia, but his style of behavior is quite different from that of the mafia. He saved Nanako and adopted five orphans—Kunikida helped him find relationships with two of the children, I went through the procedures for admission to the nursery school.

Although the Mafia was hardly a good guy, Kunikida had no dislike for this man.

Oda nodded to Kunikida as a greeting, and asked, "Is Ranpo-san there?"

"Mr. Ranpo has gone out and hasn't come back yet." Kunikida answered him calmly.

It is said to be "going out", but it is actually just because a certain manga released the latest volume today, and the first brush will give a limited edition flash card, and the bookstore implements purchase restrictions, so Ranbu took Gogol to line up to buy manga together, wanting to get the whole set There are a total of twelve special flash cards—meaning that the two of them have to line up at least six times to buy them all.

It took too long to stand in line, so Ranpo gave up taking Nanako to make up the numbers.

If other club members skipped work for half a day in order to collect some "special code cards", Kunikida would definitely frown in displeasure, but if it's a disorderly move, that's another matter.No matter what Ranpo does, Kunikida will feel that it should be so, there is nothing wrong with it.

"Mr. Ranpo should be back soon at this time." Kunikida said to Oda, "If you don't mind, you can sit in the reception room for a while."

Oda Sakunosuke nodded, and was about to walk towards the reception room when the door of the detective agency that he had just closed behind him was pushed open with a "bang".

"I am back--"

Holding a stack of torn-out special code cards in his hand, the laughter of chaotic steps immediately filled the entire detective agency. Just one person instantly made the office area, which was quiet like a pool of stagnant water a moment ago, lively, and Gogo behind him Holding a few unpacked comics in his arms.

"Ah--hahaha! Even if it's a special code, it won't trouble me, a famous detective! It's so easy to get a set together...... Kunikida, please pour me a glass of water!" He said carelessly Said, walking into the house, I saw Oda standing in the office area.

"Huh? Isn't this Oda! What's wrong? Have you encountered any problems and asked a detective for help?" Ranbu asked and walked towards the office area.

Nanako was picking up a table of messy draft paper and exercises, and wanted to change to another table to continue writing the topic, but she hurriedly pulled away the nearest office chair and sat down at an empty desk: "It's okay. , Nanako, please continue to do your homework! — By the way, bring a bag of potato chips for Dad."

Nanako let out an "oh", put down the pencil in her hand, squatted down, opened the desk cabinet, found a bag of tomato-flavored potato chips, gave it to Ranbu, and ran back to Ranbu's desk Continue to write the topic.

After throwing the manga back on the table, Gogol took a peek at the problem she was writing, a bunch of physics formulas, and various force analysis diagrams. He guessed that most of Nanako’s school homework hadn’t been written yet, so she didn’t want to be a teacher. Gogol, the homework tool man, shook his cloak, and immediately slipped out to hang out again.

"So?" After accepting the water handed over by Kunikida, he leaned on the back of the chair, bit the potato chips in his hand, and asked Oda, who was sitting in front of him, with a smile on his face, "Tell me Tell me what's wrong with you?"

"Or rather—"

"What's the trouble with the port mafia?"

The author has something to say:

When you all want Xiaolang and Nanako to talk more

Nanako: Can you do purchasing services?

Li Xiaolang:?
