This form of address made her feel pampered, a completely new feeling she had never experienced before.

In the past, apart from those annoying people in the organization who would call her by her code name, only Akemi would call her Shiho.

In the past, some people had given her nicknames, but whether it was those nicknames or the code name she didn't want to mention, they all made her feel very uncomfortable. Only the name that Guangyou gave her now made her like it from the bottom of her heart.

"Only you can call me that..."

Ai imagined someone calling her "Nizi" in her mind. Forget about feeling pampered, she only felt a chill, which could be described as "disgusting".

As she was thinking this, Kōyū, who was sleeping on her lap, suddenly stirred again. Ai stopped thinking and looked down at Kōyū, trying her best not to make any movements.

When Ai saw the expression on Kousuke's face, she was slightly taken aback and murmured, "What was he dreaming about? He looks more like a helpless child now."

In reality, the situation was far less exaggerated than Ai Haibara appeared. She was not "helpless" at all; Kousuke was just frowning, as if he was troubled by something.

"Even sleeping can cause so much worry."

Ai became even more curious about Kōyū's dream. "I'll ask him about it when he wakes up."

When she saw Kwang-woo open his mouth as if to say something, she leaned down slightly so that Kwang-woo's mouth could be closer to her ear.

The distance between the two was less than two fists, and Ai could even feel Kousuke's steady breathing as he slept, like a warm breeze brushing against her face.

When she heard what Guangyou was saying, she straightened up. At that moment, she felt that Guangyou was more pitiful than her.

She has at least one older sister by her side now, but so far no one related to Guangyou by blood has appeared.

Ai Haibara also has no way to completely solve this problem unless she can use the police system to search for DNA, otherwise she simply cannot find it.

Moreover, there are those who are not recorded in the system, making the task just as difficult as finding a needle in a haystack.

There was only one thing Ai could do for him now. She quietly took Kousuke's hand and whispered, "I'll be by your side from now on."
