People in Detective Conan are going crazy over the comments section.

Since returning from the Fukito Mountain Villa, Asakawa Yu and Akemi have returned to their peaceful daily lives. Although their days are ordinary, they have a unique charm, just as life should be like this.

But perhaps the peaceful daily life didn't fit the tone of the Detective Conan world. As time went on, Asakawa Yu always felt that something was wrong, like... the calm before the storm.

"By the way, boss, when I saw Ai this morning, she looked a little off. She looked like she had a cold, so I'm going to check on her after get off work."

Since there were no guests visiting at the moment, Akemi was happy to have some peace and quiet, but she seemed to be too worried about her sister's health, so much so that she was now feeling down.

"Has she caught a cold? Could it be that she stayed up too late doing experiments again?"

Asakawa Yu offered his own guess as to why Ai Haibara caught a cold.

Mingmei nodded in agreement, "I told her a long time ago not to stay up so late, but it seems she's been ignoring what I, her older sister, said. I'll definitely have a good talk with her when we get back!"

Although it may seem like a complaint about her younger sister, it is actually an older sister's concern for her.

"That's it..."

As she said this, Asakawa Yu slowly walked to the door and gently flipped the signboard at the door. Naturally, the 'Open for Business' on it changed to 'Closed for Business'.

"Hey? Boss, why are you here so early today..."

Aren't you very worried about Ai?

Akemi stood there, stunned. "Is that so? But..."

"Then let's leave work a little earlier today to visit her. Money can be earned anytime, right?"

Perhaps Asakawa Yu's words touched Akemi's heart, because the next second, Akemi also began to tidy up the utensils on the table.

"Since you've said so, boss, I'll gladly accept it."

"Sigh, you..."

As the sun slowly set, only a few clouds remained on the horizon, and orange light bathed the two of them, creating a beautiful scene.

"Ding dong!"

Asakawa Yu rang the doorbell of Professor Agasa's house, and the two waited quietly at the door.

Japanese elementary school students get out of school very early, and Ai Haibara and the others should be home right now, barring any unforeseen circumstances.

With a click, the door to Professor Agasa's house opened, and a head peeked out. Asakawa Yu was somewhat surprised, because it wasn't Professor Agasa who opened the door, but Edogawa Conan.

"Huh? What are you doing here?"

Conan's lips twitched slightly at Asakawa Yu's question. "What, can't I come to Dr. Agasa's place?"

"No, not at all. By the way, Ai should be here. I heard she had a cold, so she and her sister came to see her."

Conan noticed Akemi standing behind Asakawa Yu at that moment and immediately greeted her, "Hello, Ayami-neechan."

"Hello Conan, Ai Haibara..."

"Haibara is inside, but her cold seems to be getting worse." Conan made way for them to come in.

When the two entered Ai Haibara's room, they saw her lying on the bed wearing a mask, looking like her cold had gotten worse. Professor Agasa was also by her side.

"Asakawa, you've arrived."

"Thank you for your hard work, Doctor."

"It's alright. After all, I've always treated Ai like my own granddaughter. I was very worried when I saw that she had a cold."

"elder sister……"

Akemi stayed by Ai Haibara's side with a worried expression, while Asakawa Yu stood quietly behind the two sisters. Strangely, he keenly sensed that the atmosphere in the room was a little off.

When he turned to look at Conan, he realized that Conan was holding a letter in his hand and carefully reading its contents.

Furthermore, he then noticed that a series of bullet comments were floating above Conan's head, which made Asakawa Yu realize that another case was probably about to occur.

"I think something must have happened to you. If you don't mind, would you like to tell me?"

Realizing something was amiss, Asakawa Yu looked at Conan and Dr. Agasa and said...

At this moment, Conan and his friends seemed to realize that they had been discovered, so they stopped hiding and handed the envelope to Asakawa.

"Well, you can see for yourself."

After saying that, Asakawa Yu took the envelope and began to examine it. However, the more he looked, the more his calm demeanor remained, but his once dormant heart began to stir again.

It seems the time has come; he should have thought of it sooner.

The party, the full moon, Ai Haibara's cold—it was all so obvious, yet he only remembered it now.

The Full Moon arc has arrived. By now, that woman, Vermouth, probably already knows that Ai Haibara is Sherry and Conan is Shinichi Kudo.

It's likely that their room is already under her surveillance.

If that's the case, judging from the conversation between the two sisters just now, Vermouth can probably deduce that Akemi's true identity is actually Haibara's older sister.

However, there are exceptions. For example, Vermouth may not know about this and may only regard Akemi as a kind older sister who is very good to Ai. But the chances of this happening are less than 20%.

Even his personal information has probably been thoroughly investigated by Vermouth long ago.

"Do you see anything?"

Seeing that Asakawa Yu remained silent for a long time, Conan became a little anxious, but he was afraid of interrupting Asakawa Yu's train of thought, so he whispered a reminder.

"Well, so we now know the identity of the sender. No, or rather, you probably know more about him than I do."

"What do you mean?" Ai Haibara asked, her voice slightly nasal.

"Fumos, a type of liquor, you should know it, right?"

Conan and Ai Haibara nodded.

"It seems you think the same way I do. This time, it's probably one of those organizations causing trouble again," Conan calmly analyzed.

But Asakawa Yu changed the subject, gazing quietly at Haibara Ai, who was half-lying on the bed, "I think you're probably more familiar with the name Vermouth than this one."

The moment Asakawa Yu uttered the name, Haibara Ai's entire body began to tremble uncontrollably, and she even buried her head in her knees, shaking violently.

"It's okay, Ai, it's okay, your older sister is here."

Seeing this, Akemi hugged Ai Haibara with heartache. Although she had never heard of this name before, seeing her sister so scared, she knew that this person was probably not simple.

Meanwhile, in a dark room, a woman dressed provocatively sat surrounded by a pile of machines, smoking a cigarette.

"Interesting. It seems I've learned something incredible again. Things are starting to get interesting."

"I'm becoming more and more interested in you, Asakawa Yu..."
