Summary: They were supposed to be together, she and he. Everyone believed so and so did she. So, where did that detective girl come from and dare to steal him from her? She wasn't going to let her have him! After all, Love is War!

KaiShin, AokoKaito one-sided.

Author's Rant: Well, I'm writing another story~!

This was inspired when I was complaining to my friends about the teen stories in our country. All the stories that have girl loved her childhood friend and when that said friend has a girlfriend, the girl would be depressed and ignore the boy for sometime before she let him go…Just like that the girl wouldn't even try to win the boy back…

So I write this, Aoko wasn't going to let Kaito be together with Shin-chan that easily, but still…I'm a KaiShin fangirl…so don't worry about the main pairing v^^.

Beware of AU, OOC-ness and girl!Shinichi and typos and stupid grammar mistakes!

Disclaim: If I own DC or MK, Shin-chan and Ran would never be together~! Same for Kai-chan and Aoko!

Of Childhood Friend and Girlfriend.

Chapter 1:

"Mou, BaKaito! Hurry up! We're gonna be late!" a girl with messy brown hair was tapping her foot impatiently as she waited for the boy called 'BaKaito'.

And a blur of black ran past her with a cry, "Coming!"

"Ehey! Wait for me!" she yelled and ran after him hurrily.

He just turned his head back to grin at her, "Didn't you say hurry, Aoko?" and she glared at him while trying to keep up with him.

"I race you to school!" she, Aoko declared with an arm held up determinately.

"Seriously? I won't go easy on you." And he grinned again, running ahead of her though not at his full speed, just enough for her to keep up.

She smiled to herself. This was their daily things. Arguing and all but they cared for each other, understood each other very well.

Ever since he had come to her with a red rose when they were little, they became friends from then on and were always together. They grew up together. Everyone believed that they'd be together in no time and she believed so too. She liked Kaito and she was sure he liked her too, he just didn't know it yet and hadn't confessed to her. But he would one day. And they'd be together.

xxxxxXxxxxxXxxxxx

Though Kaito was a bit of a pervert, famous for his constantly peeking into the girls' changing rooms and flipping the girls' skirts-especially hers, and a prankster, everyone in the school didn't hate him, just a bit wary of him and his pranks.

And the girls in the school liked Kaito a lot. Though he was a carefree person, he still cared about people around him very much-especial her. He would always be there for you if you need his help. Not to mention he was pretty good-looking too. He was seriously a dream boyfriend of every girl but they knew he belonged to her, so they didn't make any move for him.

And Kaito was really clueless too. He didn't notice all of those things, just continuing to live and brighten up people's lives with his tricky pranks.

Everyone could see that he cared for her the most and would usually give her a red rose each day which the girls in their class envied of.

They would be together. She would make sure of that. He belonged to her.

Kaito had been acting strangely these weeks, making everyone in the class nervous. He didn't prank people as much as before and he didn't even flip the girls' skirt or went peeking in the girls' changing room. He sat silently during the class and would often take out his phone to text-which he had never done in the past, and then giggled when he received the reply. She wondered curiously whom was he texting to.

And when the class end, he would bolt off the class hurrily as soon as the bell rang and she would have to walk home alone. She would not see him again until the next morning.

She had come by his house a few times after class but his mom cheerfully informed her that he hadn't been home and he had sent her a message to not make her worry.

Where had he gone after class?

She wondered, and she was to find out today.

And as he was about to bolt like usually, she quickly blocked his way. But since he was very skill in any sports that was not skating, he easily flipped over her head and ran off with a yell.

"Sorry Aoko! But she's waiting for me!"

And he was gone.

…'she'?...so he had been meeting with a girl eh? Aoko felt her blood boiled at the thought.

She narrowed her eyes thoughtfully. Though Kaito hadn't officially confessed to her, they were already a couple in everyone's eyes and as clueless as he could get, Kaito knew and he never seriously against it, just grinned and brush it off. That's why she took it as he accepted that he liked her.

So…who was this girl he had been meeting?

xxxxxXxxxxxXxxxxx

Aoko was waiting for Kaito as usually the next morning but then his mother came out to tell her that he would not go to school today.

"You know it was raining yesterday, right? Kaito came home without the umbrella," his mother explained, "So he's sick…nothing seriously, just a light fever and he's sleeping right now."

Aoko bowed politely to her and turned to walk to school, alone for the first time she remembered.

The class was quiet without Kaito. And the entire class, from students and teacher were all relaxed but also on alert. Because who knew if he wouldn't suddenly appeared in a puff of pink smoke to grin at them with a cry, "Me, sick? You're all fooled~!"

But the class went on peacefully and Aoko kinda missed the lively atmosphere, in another words, she missed him.

He didn't appear and when the class ended, every student babbled to each other about how they didn't believe that the prankster was sick.

She went to his house immediately after school. And when his mother opened the door for her, she frowned as she saw another pairs of shoes, girl's shoes at his doorstep.

"Oh, Ao-chan," his mother smiled to her cheerfully, "Come in, he's awake and he'll be back to school tomorrow."

Aoko smiled back at her and walked upstairs, to his room.

"He'll be happy to see you, Ao-chan," his mother called after her, "And I think you'll like his friend too…have you met her?"

"Her?" she turned back to ask his mother curiously.

"Yes, a real sweet girl though a bit shy," his mother smiled at her, "Oh, sorry for holding you back, go on to his room, dear~."

And his mother walked into the kitchen while humming a happy tune. Aoko continued her walk to his room while curiously wondering about this 'real sweet girl'.

The door to his room was slightly opened, as she was about to walk in a girl's voice stopped her.

"…geez, I told you to take the umbrella but noooo, you had to prove that you are a superman that wouldn't get sick walking under the rain eh?" the girl complained though Aoko could detect no annoyance in her voice.

"Shin-chan! Don't be so mean, you shouldn't talk like that to sick people," Kaito's voice whined and Aoko peeked inside to see the back of a long black hair girl sat beside Kaito's bed.

"You're not that sick Kai."

"Am too! And where the 'chan'? You're supposed to sweetly say, 'Oh, Kai-chan, you poor cute little thing. Come here, I'll kiss the sickness away!'"

"…In your dream," the girl replied in an even voice.

"C'mere! Say it, just for me?"

"No way! I'm going home!"

And as the girl stood up and was about to leave, Aoko saw Kaito yanked on her arm, making her fall on top of him with a surprised yelp.

And she froze and Kaito placed a loving kiss on the girl's forehead, whose face now buried into his chest. She murmured something Aoko couldn't hear but she could see Kaito smiled gently and ran a hand through her long hair.

She turned and left quietly. After bowing a quick good bye to his mother, she hastily ran home.

She could felt her eyes watered but she quickly dried them. She wouldn't cry! Her eyes narrowed, she was stronger that that!

They were supposed to be together, she and he, no one was going to get between them, she'd make sure of that.
