This is my first fanfic so please be nice, everyone…

In this story, Haibara calls everybody by their last name except Ayumi and everybody calls her Haibara(-san) except Ayumi (Ai-chan), Ran (Ai-chan) and Hakase (Ai-kun).

~~~~CHAPTER 1: I'M AFRAID I HAVE SOME BAD NEWS~~~~

"Kudo-kun, I'm afraid I have some bad news…"

Startled at her sudden announcement, Edogawa Conan looked up from the PacMan game he was practicing and ran right into the enemy. Glaring at the screen like it was at fault, he sighed and put down the controller. "What is it, Haibara?"

She chewed her lip for a second before staring at his deep blue eyes. She sighed and said "Kudo-kun, I've been looking for a cure for APTX 4869 for 5 years now and I hit a dead end in my research… I hate to tell you this, since creating the antidote is probably the only reason you've kept me alive but…"

"Oi, Haibara, you can't possibly mean…" he trailed off.

"That's right Kudo-kun. There's no permanent antidote for APTX 4869. You can still use the temporary antidote but the more you use it, the more immune to it you become… I did my best," she smiled with what seemed like self-pity, "but unfortunately, my best just wasn't good enough…"

Conan ran to Haibara and started shaking her shoulders. "You can't mean that Haibara! There must be some way! Some way to get back my original form!"

"I'm sorry, Kudo-kun…"

"NO! No, you're not! If you were, you'd have the antidote by now!"

She looked at him and her usual ice-cold stare softened, "Kudo-kun, it's the truth. You always say 'shinjitsu wa itsumo hitotsu' (there is only one truth) and you have to accept this truth…"

"NO! NO! You're lying! You just don't want me to get back to Ran!"

Her eyebrows went up at that statement and she smirked, the gentleness in her eyes disappearing, "Don't flatter yourself, Kudo-kun."

Conan glared at her but seeing her aquamarine eyes, he turned away. He ran outside and slammed the door. "Dammit…"he muttered.

Thunder suddenly roared and all of a sudden rain poured, wetting the small detective. "The weather and I seem to be in sync today," he said while smiling bitterly.

Suddenly, the rain around him stopped, making him look up. There was an umbrella, shielding him from the pouring rain. He stared in surprise at the person who was holding the umbrella. "I wouldn't want you getting sick now, tantei-kun." The small scientist said, smiling gently.

He broke down, hugging Haibara as if she was the only lifeline keeping him in the world. She let go of the umbrella, letting the rain hide the tears of the small detective and put her arms around him. "Dammit, Haibara… Dammit."

The two stood there in silence, getting comfort from each other. After a while, Conan pulled away and stared at the ground, as if afraid to look in her eyes. "Thanks Haibara. And sorry, about what I said before."

"Don't mind it, Kudo-kun. If you do, I'll give you Hell as punishment." she said, smiling. "Let's go inside, I don't want to catch a cold because of you."

"Ne, Haibara," Conan said as they walked towards the house, "Is it okay if I stay the night?"

"I'm sure Hakase won't mind. But you better call Mouri-san. She might be worried about you."

"Yeah, I'll do that."

~~~~THE NEXT DAY~~~~

"Oi, Haibara," said Conan as they he picked on his food.

"What is it Kudo-kun? And eat your food. Hakase put a lot of effort just to make breakfast."

"I know that, but I don't want to die yet… Anyway, ummm…"

"Spit it out, Kudo-kun."

"What? The food or what I want to say?"

She glared at him.

"Just kidding. Ummm… What I wanted to say is… Can I have the temporary antidote? The thing is…"

"You want to be yourself when you tell her you won't be coming back?"

"Yeah… Something like that…"

She sighed, "When you finish, follow me to the lab. And bring some of your clothes."

His face brightened. "Thanks Haibara!"

~~~~IN THE LAB~~~~

He peeked into the lab, opening the door just a little bit. He saw Haibara staring at the computer, her back to him. He debated inside his head whether to barge in or announce his entrance.

"Come in Kudo-kun."

He jumped, startled that she knew he was there. "How did you…?"

"I was trained by the Organization Kudo. I could feel your presence."

"I-is th-that so…" he said while carefully walking inside.

"What's the matter Kudo? Scared?" she asked with a smirk.

"NO!" then blushed, embarrassed at his outburst. "It's just… I don't really know what to say to Ran…"

"Awww… Poor Kudo. Just like a lost little kitten…"

'"Shut up!"

"Don't you dare raise your voice at me, Kudo." She sighed and then said, "It doesn't really matter what you say to her. Just tell her what's in your heart. That'll probably be enough…"

Conan looked up, surprised at her revelation. "Yeah, I guess so…"

"So, you ready?"

He nodded, afraid that words might fail him.

"Take this. It's a different antidote. But from what I can tell, it'll only turn you back into your real form for about 12 hours. Be sure to come back before 11 hours pass. And… to use the antidote anymore will endanger your body. I suggest that this is the last time you revert back."

He took the antidote and entered the toilet. (this means he entered the CR okay? I don't mean he entered the toilet bowl if that's what you're thinking)

He swallowed the antidote and moments after, started feeling the burning sensation. My bones… feel like… they're melting… "AAAAAAAAAAAHHHHHHH!!!!!"

Haibara, hearing him scream said to herself, "That's why I don't like using the antidote."

Ten minutes later, the door opened and out came Shinichi Kudo. She observed him for a few seconds and said "It's 11 o'clock right now Kudo. Be sure to come back before 10. I don't want to risk any chances of her finding out your true identity."

Shinichi just smiled at her and said, "Thanks Haibara, for everything."

"Baka. If you say stuff like that it's like you're never coming back."

"Haha, I guess you're right. I'll borrow the phone. I want to call Ran and tell her to meet me." And with that he rushed out of the laboratory, leaving the little scientist behind.

"Baka…"

~~~~CHAPTER 1: I'M AFRAID I HAVE SOME BAD NEWS end~~~~
