Those discussed before are all speculations of Guangyou. It can be said that he has made a brain hole, and no one can jump to conclusions without evidence.

It's fine if Guangyou's idea is wrong, but if you guess it right, then it can be considered as providing a little idea for the case.

Solving a case is not afraid of the difficulty of the case, but afraid that there is no idea and direction to solve the case. This is the same as doing math problems. If there is no idea, even if you look at it for a year, you will definitely not be able to do it.

Even if this idea was found to be wrong in the end, at least it was put into practice.

At this time, Conan had trot to the bathroom, ready to tell their guess to Officer Mumu.

Taking into account the inaccuracy of the guess, Conan did not tell the truth, and the news was only half of the story, only that the man called the dead.

As for the passbook, Conan plans to wait for the passbook to be placed in a conspicuous place for the police to find out so that the police officer will not carry him out again.

After listening to the news provided by Conan, Officer Megome nodded thoughtfully, and then said to Takagi, "Brother Takagi, you take a few people to the nearby piano store to investigate...well, those who have pianists. Don't miss the restaurant or cafe."

"Yes!"

After an energetic response, Takagi took a few police officers to investigate nearby.

Seeing that his goal was achieved, Conan found a reason and left near the bathroom. He wanted to look for it for a while to see if there were any missing clues.

On the other side, it is impossible for Guangyou to sit on the sofa waiting for the police to close the case. At this time, he is looking for clues on the second floor with Xiao Ai.

The focus of the investigation was placed in Kuroki Yuri's bedroom. To be precise, it should be Kuroki couple's bedroom, but Kuroki Jianer is not at home on weekdays, so this bedroom is basically only used by Kuroki Yuri.

The area of ​​the room is not big. There is a double bed in the middle. There is an LCD TV on the cabinet opposite the bed. There is a dressing table next to the TV with some cosmetics.

The drawer under the dressing table was open at this time, and Guangyou knew that this must be Conan's handwriting without thinking about it. Presumably the passbook was found in this drawer.

Standing in a messy room, Xiao Ai glanced around and asked, "Do we still need to find something?"

Guangyou, who was looking for clues, answered without raising his head: "Keep looking, maybe Conan will miss something."

After hearing this, Xiao Lai was going to stay in this room to help Guangyou look for clues together. As soon as she was about to start, her eyes were attracted by the photos hanging on the bedside wall.

The person in the photo is not the point, but the theme of this photo is a bit special, and it is this theme that makes her self-sufficient.

"Xiao Ai, what's the matter with you?" Guangyou just turned his head to find Xiao Ai who was stunned in place. Following her gaze, he also saw the picture hanging on the wall, and then he laughed.

The sudden laughter made Xiao Ai wake up from her self-repair. Seeing Guangyou standing next to her, she hesitated for a while and sighed, "This dress is pretty."

Looking at the picture, Guangyou said with a serious expression: "You look better in your clothes. Sooner or later, you will dress like me in a suit."

Such a reply made Xiao Ai very satisfied. Thinking about the business at this time, she urged with a smile on her mouth: "Okay, let's continue looking for clues."

"Oh."

Originally Guangyou wanted to continue talking, but she skipped this topic.

However, look at her expression...

Is this a promise?

...

It's a pity that in Kuroki Yuri's room, Guangyou and Xiaoai didn't find any useful clues at all, so he changed another place and continued searching.

This time I searched Kuroki Tetsuya's room. For this room, Guangyou didn't have much hope. He didn't think there would be any clues in this room, so he simply went in and took a look.

At this moment, Xiao Ai stood in front of Kuroki Tetsuya's desk, looked at the photo album spread out on the table, and said with emotion: "No wonder the kid is looking for a detective."

Hearing this, Guangyou also leaned forward to take a look, and then nodded in agreement: "I know this family used to be very happy, it's a pity..."

The side of the photo album spread out is all the previous photos of the Kuroki family, either on the grassland, by the sea, or in the amusement park, but no matter how the location changes, the three people smile on the faces of this family They all seem so happy.

The happy smiles of the three people in the photo reminded Xiao Ai of some past events, and only listened to her softly: "Actually I am quite envious of him, after all, he has enjoyed it for a while, and I..."

Having said this, Xiao Ai was silent, and then smiled and said: "Forget it, everything is different now..."

Hearing the first half of Xiao Ai's sentence, Guangyou thought she was touching the scene again, so he opened his hands and hugged Xiao Ai into his arms without hesitation, and said softly: "And you have me, silly Nizi."

"Don't worry... didn't you hear the second half sentence?" Xiao Ai felt helpless at the same time, feeling a warm current in her heart, "rest assured, I am not as fragile as you think, let alone now I..."

"What's more, now I have you..."

Her voice was very soft, but the two were close, and Guangyou could hear it clearly. Hearing this sentence, the stone in his heart also fell.

She said that she was not as fragile as he thought, Guangyou agreed, but it was just not as fragile, the word strong is still far from her, no matter what, Xiao Ai is just a girl of seventeen or eighteen.

Because of this, when Guangyou heard the first half sentence, she was worried that she would be depressed for a while because of these photos, so that he didn't hear the second half sentence at all.

However, after hearing what Xiao Ai said to him this time, Guangyou understood that he was too worried. Although he understood this, he still did not let go. He still held Xiao Ai and buried his head on her shoulders. .

"Xiao Ai, you won't say anything like this in the future, okay? Because I still can't help but worry about you..."

A slightly low voice reached Xiao Ai's ears, causing her heart to tremble, her eyes gradually softened, and she replied: "Okay, I promise you."

"Get up, there is still work to be done."

"Let me hold it for a while."

...

After the two men calmed down, the investigation continued. Guangyou picked up the album on the table and began to turn page by page.

Immediately afterwards, the two suddenly noticed that there were a lot fewer photos of the three in the album. More importantly, the smiles on Kuroki Kenji and Kuroki Yuri's faces gradually changed, as if they lost the taste of happiness.

"The time for these photos..." Xiao Ai glanced at the time in the lower right corner of the photo and said, "It seems that they were all taken in the past year. It seems that the Cold War is indeed a long time. It is no wonder that children can feel it. There is something wrong with the relationship between the parents."

"Well, these two people also specially acted for Kuroki Tetsu, but their plan fell through." Guangyou said, turning the album to the next page.

When he saw the photo behind, the motion on his hand suddenly stopped, and after a long time he said: "Sure enough."
