"Let me think..." Hattori Heiji raised his chin slightly, thought for a moment, and then said, "Just bring me a bottle of oolong tea."

"What about Kōyū and Ai?" Kazuha looked at Kōyū and Ai again.

“I’m going there too,” Ai replied, glancing at the convenience store not far away.

"Okay." Kazuha nodded.

"What would you like to drink?" Ai turned to look at Kousuke and asked, "Mineral water or juice?"

Before Kōyū could speak, Ai made the decision for him, "Mineral water it is."

"I'll take your word for it, mineral water." Guangyou paused for a moment, then realized what Ai meant and nodded with a smile.

After discussing what to buy, Kazuha and Ai walked towards the convenience store together.

...

Six minutes later, Kazuha and Ai, each carrying a bag, walked out of the convenience store and returned to the bumper car area.

"Your bottled water."

Taking the bottled water from Ai, Kōyū unscrewed the cap, tilted his head back, and took a big gulp. Then he screwed the cap back on, leaned over, and glanced at the bag in Ai's hand.

Then Kōyū asked, "Ai, what else did you buy?"

"I bought some bread." Ai opened the bag, showed it to Kōyū, and then took out another bottle of mineral water and handed it to him.

Although Ai didn't say anything, Mitsuyoshi understood what she meant.

After taking the bottle of mineral water, Guangyou unscrewed the cap and handed it to Xiao Ai.

Kazuha and Ran, who were standing nearby, witnessed this scene.

Meanwhile, Heiji Hattori was drinking oolong tea and chatting with Conan, and neither of them saw what was happening.

"Give it a try," Ran's voice rang in Kazuha's ear.

"Hmm." Kazuha nodded, took a deep breath, as if doing so could relieve her tension.

After hesitating for a while, Kazuha took a step forward, walked up to Hattori Heiji, and handed him the bottled water in her hand.

At the same time, he called out Hattori Heiji's name.

"Heiji..."
