Lunchtime.

Noriko Amamiya eats the bento brought from home, which she naturally makes herself, and her mother is useless except for being beautiful and leaving her better genes.

Selling cuteness and coquettishness is much better than her, and she occasionally thinks about it, who is her mother?

Shinichi Kudo doesn't know why she went, as if she was keen to find the owner of the two love letters she received.

Seeing him in class, he is diligently taking notes, planning, classifying clues and so on.

The old detective is up.

Suzuki Sonoko sandwiched a small piece of chicken from Noriko Amamiya's lunch box and chopped it up, "Noriko really likes to eat meat." ”

Xiaolan reminded: "When I was a child, I just ate it, but now it's easy to get fat." ”

"I'm the type with a high basal metabolic rate, and generally speaking, I can't get fat if I want to, and I have fitness." Noriko Amamiya was fearless, took a small jar of cumin powder out and asked Yuanzi, "Do you want it?" ”

Sonoko shook her head, wondering what is your basal metabolic rate?

Xiaolan explained: "It is the minimum energy necessary to maintain the basic activities of life, and the muscles are high, right?" ”

Yuanzi was curious: "Why does Noriko still have a cold and fever so often?" ”

Noriko Amamiya had to qualitatively say: "Two different things! ”

Otherwise, the delicate picture of muscular men with a cold and fever every day will emerge.

By the way, Xiaolan is a karate club and is heading towards combat effectiveness, and Yuanzi is the school tennis club, and if they have enough training, their figure will naturally be maintained very well.

After eating the meal during the chat, Sonoko wanted to drink a drink, but he ate a lot of Noriko Amamiya meat and didn't want to leave, so he decided to guess who would buy the boxer.

Noriko Amamiya was defeated neatly, and with bad luck, she was defeated by Xiaolan and Sonoko in one round.

There is no way to lose to Xiaolan, how many times Xiaolan has won the lottery and has traveled, it is a number worth counting, and Gong Jizi has a little luck, which can't be compared.

There are also tips for guessing to increase your chances of winning, but she's not that boring.

"I want Coke!"

"Juice is fine."

“OK。”

Noriko Amamiya wrote it down and went to buy it, the vending machine was around the corner at the end of the hallway, and when she passed, she found Shinichi Kudo leaning against the wall and drinking canned coffee while looking at the small notebook in his hand.

"What are you doing here?"

Kudo Shin didn't raise his head: "Solve the puzzle!" ”

"Oh..."Noriko Amamiya nodded, isn't this mystery the difficulty of Dr. Asasa, but the difficulty of Xiao Ai? It shouldn't be.

"Is this coffee good?"

After buying juice and cola, Noriko Amamiya asked by the way.

"Black coffee, it's bitter." Kudo Shinichi put the notebook back in his pocket, and was a little surprised when he saw this: "You help Xiaolan and Yuanzi buy drinks?" ”

"With such surprise? It's not your wife's luck. ”

Noriko Amamiya rolled her eyes.

“…”

Kudo Shinichi said that talking to Noriko Amamiya is full of landmines, why is he a wife? I'm so embarrassed.

Seeing that the detective blushed and did not admit it and did not completely deny it, Noriko Amamiya shook her head, professional, and 99% of her IQ was used to solve the case.

She only came to water the love flower occasionally, and then asked him how his investigation was?

Kudo Shinichi was immediately bright.

She analyzed the material of the two envelopes, as well as the time when they were put in her shoe cabinet, and used this as a clue to lock the envelope this morning, according to his investigation of the source of this envelope in the school There are three, one is the student union, one is the activity committee, and the other is the letter club.

He checked for a long time in the morning, and for now he can be locked as the president of the Correspondence Society.

In fact, it's the Correspondence Club.,A group of people who love letters.,He found out that the student union has no recent record of the use of envelopes.,So it was ruled out.,The activity committee has been busy with the Tianchang Festival recently and didn't help him check this kind of thing.,But he found that the vice president of the activity committee and the president of the letter club are the same person.,And he was responsible for purchasing this style of envelope.。

The most important thing is that I saw each other's handwriting from the activity committee and the letter agency, and after repeated comparisons, it was confirmed, and the other party came very early because of the activity committee's affairs, so he had time to commit the crime.

Kudo Shinichi's reasoning after the investigation may be wonderful, but Noriko Amamiya scratches her head and finally chooses milk.

"Can you listen to other people's reasoning!!"

Noriko Amamiya held three bottles of drinks: "I want to say it's exciting, but this person is actually not very important, anyway, I will refuse in the afternoon." ”

Kudo Shinichi frowned, damn it, this is for him to have nothing to do.

He put on a face that the puzzle-solving process was very easy anyway, and there was no challenge, and returned the letter to Noriko Amamiya: "The other party is a very rigorous but idealistic person, you can do it yourself in the afternoon, don't you want to drink coffee?" ”

"Roger." Noriko Amamiya nodded, and then gave him a blank look: "A sweet girl like me, can she drink coffee?" ”

“...”

I don't know why, it's even more infuriating than not listening carefully to his reasoning.

Noriko Amamiya went back with three bottles of drinks and a love letter, and on the way, a classmate said kindly: "Do you need help?" ”

"Ah, thank you very much, but no, just a few bottles of drinks, I think that classmate over there needs help, thank you."

Noriko Amamiya smiled sweetly.

The kind-hearted classmate was about to go over to help as if he had stepped on cotton, but he saw that it was his classmate who was holding a box of teaching materials here.

"Ota-kun? Are you here to help me?! ”

"No, I'm passing by."

Ota looked at the back of Noriko Amamiya and breathed a sigh of relief, although yesterday's envelope Amamiya-san didn't seem to have received it, but today I also talked to Amamiya-san!

The female classmate holding a box of teaching materials stepped on his feet hatefully,

"Ahh
