[Day 1]

Thinking about yesterday all over again, she made some notes. She was able to prolong the effects of antidote so far. Still there were few things, she thought were important to attempt to. Next antidote may be a step closer to that of permanent one. Anyway, she had to stop now, or else she would be late for her school.

"Ai-kun. You better get ready or you will be late." Professor informed her from upstairs.

"Yes, hakase", she answered. 'I can collect his medical analysis after school, today' thought she.

The girl, recognized as Haibara Ai, by remainder of world, except those, who knew who she truly is. Miyano Shiho, codenamed Sherry, was long dead. Now only Haibara Ai was to live.

After she got herself ready, she went outside to see that her friends are almost near her house. They all chatted about latest events, new episode of Kamen Yaiba; and now, they were on the topic of yesterday's case.

"Oi Conan" Genta called.

They all looked in the same direction. There he was standing with his 'neechan'. He ran to them.

'Something seems strange', she thought and looked away from high-school-detective-stuck-in-a-child's-body. 'I should not waste more time after school to inspect after-effects of antidote.' She could not put what it is, but something seemed strange today.

"I said," says Mitsuhiko, "I heard that Kudo-san solved some case yesterday and it was brilliant".

"Ah, thank you", said Shinichi, and the next moment, caught his breath.

"What?" asks Ayumi.

"Really?" yells Genta.

"Why are you saying thank you?" asks Mitsuhiko.

Haibara interrupts, "he is his cousin and mentor, you see. Isn't that so, Edogawa-kun?". 'He will let it slip someday,' thought Haibara. 'Now, you owe me a favor, Meitantei.'

"Yes. That's the reason," Shinichi get along with the reason Haibara made.

"Is that so? Well can we meet him, Shinichi-san, that is", says Mitsuhiko.

"Yes, Conan-kun?" asks Ayumi.

"You better make him meet us, then we will go to eat with him", Genta says.

"I'll ask him. But he's on very hard case right now, that I don't think he could make it,"said Conan.

Haibara was going to remind Shinichi of her newly-owned favor, but at the same time, they had reached school, so she dropped the thought.

They were changing their shoes with slippers, and that's when it occurred to her. Something caught Haibara's attention. It made her wonder, all the procedure she applied to prepare the latest antidote. She was now desperate to perform the inspections of after-effect of antidote of APTX 4869. It may have looked nothing of importance to others, but to the scientist-working-on-antidote-of-most-dangerous-drug-that-can-be-used-as-poison-but-may-sometimes-spare-lives-on-account-of-ten-years, it was important.

It was a small action made by Conan, that did all of this.

He placed his shoes in locker without any efforts.

The only wrong thing about it was that the locker was higher for his reach, until today.
