Although Gangnam Linyi National High School is an ordinary high school in Seoul, it is very large, with a total of nearly 3,000 teachers and students.

When Kim Yoon-ho and Shin Dong-hae arrived, they were warmly received by the principal.

In the principal's office, after greeting each other, as soon as he sat down, Kim Yun-ho asked, "Principal Li, when did your school find out that Shin Jing-ah and Ko Hyun-jung disappeared for no reason?" ”

"It was last Wednesday morning that the teacher found out that the two of them were absent from class for no reason and reported it to the Academic Affairs Office. Subsequently, Shin Jingya's parents came to the school to verify her whereabouts, and this was discovered. Principal Li replied directly, obviously already having a draft in mind.

"I heard that Shin Jingya and Ko Hyun-jung are both boarding students, did they spend the night in the dormitory last Tuesday night?"

"This..."Principal Li hesitated for a long time to say why, and seemed to have some concerns.

Kim Yoon-ho thought about it and understood what Principal Lee was worried about. He was afraid that the school would take responsibility and have a bad impact on the school and himself.

Jin Yunhao said expressionlessly: "I hope you understand that now that the two living girls are missing, finding them as soon as possible is the most important thing, and everything else has to make way for them."

In addition, I would like to assure you that as long as your school fully cooperates with our investigation, I will not take the initiative to hold you accountable after the fact. If the family investigates, I will also help you mediate. ”

"Hehe, that's good, that's good." Principal Li wiped the sweat from his head, and after not worrying, he took the initiative to explain the truth:

According to the dormitory warden's records, Shin Jing-ah and Ko Hyun-jung were not in their dorm room on Tuesday night.

You don't have to look at me like that, Investigator, and I know that our school is negligent in this regard. But we also have difficulties. There are more than 3,000 students in the whole school, and it is impossible to cover everything.

And for Shen Jingya and Gao Xianzhen's skipping class and not returning home at night, we also talked to their parents. However, the effect is minimal, and their parents are not enthusiastic about managing and educating their children. Relying on our school education alone really doesn't have much effect. ”

"Did the two of them go to school last Tuesday?" Kim Yoon-ho asked.

"Well, I attended classes during the day, and there were students who met the two of them at seven o'clock in the evening."

……

During the conversation with President Lee, Kim Yoon-ho learned some basic facts, and at the same time, Yoon Kook-hong, Song Eun-ji, Lee Hye-na, and Park Ji-cheon also arrived one after another.

Kim Yoon-ho asked Principal Lee for an idle classroom to serve as a temporary case-handling place. On the blackboard in the classroom, the relevant information about the case was recorded, which was dictated by Kim Yunhao and written by Shin Donghae.

In front of the blackboard, Kim Yunhao stood upright, knocked on the blackboard behind him, and commanded the others in the room:

"Take a look, the basic information of Shin Jingya and Ko Hyun-jung is recorded on the blackboard. When you make new discoveries, you have to record the information as well.

Let's explain the task.

Investigator, you are responsible for interrogating the teachers of the school and obtaining basic information about the missing person while he or she was in school; Interrogate school staff to see if there have been any strange, suspicious characters in the school recently. At the same time, the school's surveillance footage was retrieved.

This classroom, as a confession was recorded live.

Investigator Shen, you are in charge of interrogating the missing person's male classmates.

Secretary Song, Secretary Li, the two of you are responsible for interrogating the missing person's female classmates

Captain Park Zhitian, please take the people with you to maintain order on the scene.

Now, action. ”

"Yes." The others echoed in unison.

Even Park Zhitian and the other three policemen who came with him nodded in response.

Park Zhitian is a veteran police officer, and he also sees something unusual about this case.

I am grateful that Kim Yoon-ho has not forgotten him as a person, and let them participate in this case and get a share of the credit, and I am very glad in my heart for the decision to help Kim Yoon-ho in the first place.

Therefore, for Kim Yunhao's orders, Park Zhitian and his three cronies will carry them out to the letter.

――

While the others were working separately, Kim Yoon-ho, accompanied by Shin Jing-ah's teacher, came to Shin Jing-ah and Ko Hyun-jeong's dormitory to investigate in person.

In Shin Jingya's desk and cabinet, a large number of SJ's posters, postcards, albums, etc. were found. Although Kim Yunho doesn't know much about the market, it can be seen that Shin Jingya must spend a lot of money in this regard.

However, this discovery only confirms the previous conjecture that Shin Jingya is an avid fan of SJ. But other than that, no other clues were found.

When Kim Yoon-ho investigated Ko Hyun-jeong's desk and cabinet, he also found SJ's posters, albums, etc., although the number was not as good as Shin Jing-ah's, but there were quite a few, which was completely beyond a normal range.

And what caught Kim Yunhao's attention was that compared with Shin Jingya's ordinary clothes, Ko Hyun-jeong's clothes were very high-end, and there were many expensive brands. Among them, there was one piece of clothing that Kim Yun-ho was particularly impressed, because this dress was the same one he bought for Kim Yun-hee yesterday.

A high school student wearing millions of clothes?

Kim Yun-ho asked the question in his heart: "Excuse me, how is Ko Hyun-jeong's family background?" ”

The teacher thought about it for a moment and replied, "As far as I know, Gao Xianzhen's family background is average, she is a single-parent family, and she was raised by her father. And her father is also an ordinary clerk, and I met the parent when I entered the school, dressed very ordinarily. ”

Hearing this, Kim Yun-ho roughly guessed a possibility.

――

After several hours of visiting, everyone completed their work.

In the classroom, which is often used as a temporary case, several tables are placed together, and Kim Yoon-ho and others are sitting around.

On the main seat, Kim Yun-ho banged on the table, staring at the information on the blackboard, pondering and analyzing.

After a long silence, he showed a knowing smile, and then turned to the others and said, "Tell me what clues each has in their hands, Secretary Song Enzhi, you come first." ”

Song Enzhi stood up, opened the notebook, and read: "When Secretary Li Huina and I interrogated the female classmates of Shen and Gao, we mainly found two things:

Shin and Gao are fans of the SJ boy group, and they often skip classes to watch SJ's performances at their own expense.

In addition, Shin Jingya usually dresses ordinarily, but she is lavish when buying items such as music albums. Ko Hyun-jung also bought a large number of albums, and at the same time she was gorgeously dressed and expensive.

The interviewed students thought that the reason why Shen and Gao, who were from ordinary families, were able to buy these Eastern Evil Spirits was because they were doing ...... Aid in communication. ”

After Song Eunzhi answered, Shin Donghai then added a report: "I also found this content on this side.

Shin Jingya and Ko Hyun-jung are very beautiful and are evaluated as class flowers by their male classmates. Many boys tried to chase the two, but to no avail.

It is worth noting that there are also some boys who are very disgusted with Shen and Gao, and they think that Shen and Gao do help socializing in private. However, there is no evidence, it is all their conjecture. ”

Shin Jing-ah and Ko Hyun-jung are doing assistance communication?

At present, the reports of Song Eunzhi and Shin Donghae all point to this.
