After leaving Matsushima's house, Fujiwara Yuu and others headed towards the house of the neighbor who provided the clue.

Fujiwara Yu still didn't know the suspect's name, so he couldn't help but ask:

"Otaki-senpai, can you tell me his basic information?"

Otaki Goro flipped through the notebook in his hand and read out all the information recorded about Yamamoto Koji:

Yamamoto Koji, a 30-year-old male, works at a packaging design company. He has lived alone since divorcing his wife, Satomi Fukuda, a year ago. His colleagues describe him as a polite and helpful person, and even his neighbors think he's courteous and never gets into conflicts.

Fujiwara Yu and Hattori Heiji both showed thoughtful expressions. They both got one point from this basic information, which was: this warm-hearted neighbor had an excellent reputation outside, and his colleagues and neighbors all thought he was a good person.

But if we dig deeper, we can conclude that his social relationships are very simple.

Because everyone who came into contact with him used words like "polite" and "courteous" to describe him, which are often used in social interactions with strangers. Otherwise, words like "friendly" would be used to describe him.

Therefore, it is not difficult to see that Yamamoto Koji uses a polite sense of distance to draw boundaries whether in dealing with relationships between colleagues or neighbors.

"Otaki-senpai, do you know who filed for divorce?" asked Fujiwara Yu.

Otaki Goro took out the notebook he had stuffed back into his pocket, found the note in the lower right corner of the page, and replied:

"It was his ex-wife who initiated the divorce application. I'm not sure about anything else."

"That's a bit strange."

"Huh? What's strange about it?" Otaki Goro was a little confused. Divorce was a very normal thing in Japan, so he didn't think there was anything strange about it.

Hattori Heiji stopped and shifted the brim of his baseball cap forward. He realized something was amiss and said quickly:

"Brother Yingsi, do you think that as a good man, he has no reason to divorce his wife? Or...why would his wife divorce a husband with such a good reputation?"

The five-yen coin that he was still playing with in his hand was put into his pocket. Fujiwara Yu looked at Hattori Heiji with satisfaction. The detective who would be needed by the victims in the future is gradually growing up. The young people are really formidable.

He nodded in agreement with Hattori Heiji's guess, then hooked his finger at Otaki Goro and whispered in a hoarse voice:

"Senior, please mention your ex-wife in front of him later. I want to test his reaction."

"Okay, no problem."

The four of them arrived at the iron gate of Yamamoto Koji's three-story house. Otaki Goro pressed the doorbell on the wall and waited for the other party to ask first before answering:

"Mr. Yamamoto, I'm sorry to bother you again. I'm the police officer who just came here. I want you to think carefully about the vehicle. Is it convenient for you now?"

"It's you, Mr. Police Officer. Please wait a moment, I'll open the door right away."

The front door opened, and Yamamoto Koji, wearing only a thin black shirt and even slippers in this weather, came out to greet them. As he approached, his eyes fell on Hattori Heiji and Toyama Kazuha, and he said in surprise:

"Hmm? Who are these two kids?"

"Don't worry, Mr. Yamamoto. They are the first witnesses to the case."

"Is that so? Then I'll prepare some juice for you. Please come in."

Fujiwara Yu was the last to enter. He glanced to the side and noticed the CCTV monitor at the entrance. While Yamamoto Koji was opening the shoe cabinet to get his slippers, he reached out and pressed the green button. The monitor showed the street outside the iron gate.

He quickly pressed the red button, making sure the display was off before looking meaningfully at Yamamoto Koji. So his question about who they were was completely an act; he could clearly see through the display that they were police officers.

This also explains one thing. Yamamoto Koji knew they were coming a long time ago. He must have seen them from a high place. This house has three floors. From the outside, the third floor should be just an attic... So is it in the attic?

Haha, that’s interesting. There’s definitely something wrong with this guy.

Yamamoto Koji didn't know he was being suspected. He kept a polite smile on his face. He turned and walked into the house to help put the slippers away. Then he walked into the kitchen and asked while opening the refrigerator door:

"Can you two have orange juice? Or would you like some soda?"

"No, we're not thirsty," Hattori Heiji refused directly. He had no interest in eating and drinking at the suspect's house. He had to find a way to find a flaw in the suspect, or find evidence that would prove he was the murderer.

"Don't be polite to your brother."

Hattori Heiji frowned, looking somewhat unhappy. He hated such hypocritical people trying to get close to him. Toyama Kazuha, who was standing by, was worried that Heiji's words were too harsh, so she quickly covered his mouth with one hand and explained:

"I'm not being polite, it's just that we just witnessed a murder scene and don't have much of an appetite for drinks."

This sentence instantly blocked Yamamoto Koji's next words. He rubbed the back of his neck with a wry smile, and said in a gentle tone:

"I'm sorry, little Yuanshan, I wasn't thoughtful enough. Let me pour you some boiled water."

Toyama kid? Fujiwara Yuu and Hattori Heiji couldn't help but look at each other. How did this guy know his name?

Hattori Heiji was still confused, but Fujiwara Yuu remembered the diary. Could it be that the murderer had looked through it after committing the crime?
