A/N: thank you for the last chapter reviews.

Sorry if I updated late. School .

oh yeah, I did say back then that Conan can absolutely sing in this fiction right? Hehehe time to turn the table.

DISCLAMER: I DON'T OWN DC AND IF I DID RAN IS WITH SOMEONE ELSE AND CONAN IS WITH HAIBARA.

P.S. I'LL MAKE CONAN A SINGER NOT JUST A HANDSOME SOCCCER PLAYER.

HAHA, crazy me XD.

CHAPTER 6: One and Only You

'This is such a great weekend!' Conan thought happily as his and Ai's hand were entwined together as they walk back home after they picked up some romantic movies from a store, (A/n: Just think of a random cheesy romantic movie. I don't about romantic movies XD).

He tried to come up to something to start a lovely conversation with her but she beat him to and its not a good start,

"Why are you doing this?" she asked emotionless as if she denies that she like what's happening between to her and him right now. "Are you just forcing yourself to move on and leave HER behind?" with a bitter emphasis to her. "Are you using me?" she keeps on asking those questions which makes her stop walking and hang heard head slightly with sadness and let go of Conan's hand.

This made Conan a bit sad. He already missed her soft hand.

"Why do you think that I am only using you?" he answered as confident as he can. "You don't trust me, do you?" This time, sadness can be felt from his every words.

"No. It's not like that."

"What then?"

"I just wanted you to prove it. Prove all those words that you told me at the park. I don't want to get hurt anymore. I have received enough pain through my whole life. I couldn't take anymore." she almost broke down through the whole thing but still manage to stand still.

He smiled but that smiled didn't meant anything bad but a smile of confidence and love for her. He is ready to prove it anytime. He grabbed her hand once again and flashed a smile before he dragged her along he promised, "I'll definitely prove it to you. Don't worry." She couldn't do anything but to trust his every words.

"If you just put those things aside, your lovely smile shows." he teased with a huge grin on his face, Ai just blushed and remained speechless.

~In Hakase's living room~

'I hope I didn't sound stupid earlier.' she thought sadly as they enter the mansion.

"Why are you still so down?" he said worryingly. "Go ahead sit on the couch and watch the movie before me, I'm just going to get something from my house. I won't be long." after that he ran off to his house.

She just sighed and follow what Conan just said. 'Wait, why am I doing? I won't follow orders to anyone.' she thought annoyingly but she then smiled and whispered "I guess I can always make an exception." With that she walks towards the DVD player and fed it with the DVD, found herself a comfortable spot on the couch and start watching.

~Meanwhile at Kudo's Mansion~

He scanned his big library containing all of his mystery novels including his dad's. But this time he's not looking for a mystery novel. He's looking for an instrument, not his violin but his acoustic guitar.

"I knew I can use this thing once again." he whispered to himself as if the guitar was alive. "Good thing I asked dad to get me a teacher for vocals and guitar lessons." he chuckled softly.

~Flashback~

(A/N: months before valentine's day and still best friends in this moment but I wanted it to be sweet best friend thing. You'll see what I mean XD)

"Oi, Ai. Do you want me to sing this Valentine's Day? Just a little gift for my best friend what do you say?" Conan said happily while sitting with Ai on a garden hammock, his left arm around her shoulders while Ai is reading her fashion magazine on a sunny Sunday morning. They are just 'best friends', that's what they say to everyone they knew. But they know they act more than that. This makes Conan's parents, the Mouris, the professor, the shounen tantei-dan, and the Osakan detective Hattori Heiji suspicious about their true relationship but at the same time happy for both of them. They all knew, except the kids and Ran, that they can't go back to their normal body because there is no antidote, so whatever they had now they have to accept especially Conan's crush for Ai.

"You don't know how to sing." she said without a second thought. "And will you please remove your arm around my shoulder before I snapped it out of its position." she threatened him.

"Ooohhh, I can sing I just need some.."

"Some?" she cut him and raised an eyebrow.

"Okay, a lot of practice."

"aaand?"

"and a great teacher" he finished chuckling nervously.

"Very good." she giggled a little as she looks up to Conan and she taps his cheek softly. "And now get off me." she continued with a cold scary tone with a cold scary glare.

'Hehe, I'll play for a bit.' he thought almost evilly with a wide grin followed by a soft cackle.

"I said get off me not laugh evilly at yourself , baka." she reminded him again now annoyed and looks like at any moment she is ready to snap off the arm that's on her shoulder.

"Why? Is it too much for you? I kinda like this, as a matter of fact I feel like I'm going to take a nap rrrright here at your shoulder." he said as he chuckle his way to Ai's shoulder. He didn't think twice. He knows that he is just a moment away from snapping off his arm but he still totally did it. His head is now comfortable on its position and to show that he is serious about taking a nap on her shoulder, he shut his eyes and pretend to sleep. 'Why isn't she moving?' he confusingly ask himself as he opened his one eye to take a peek out of his best friend's angelic face.

'Heh, I knew this will come.' she thought smiling but Conan didn't notice as he shut his eye and pretend to sleep. 'You choose to play with the wrong person Conan Edogawa.' at that thought she puts away her magazine and threw on the ground. Conan then felt something heavy laid on his head.

'What in world is this...' as he opens his eye and looks up to Ai, he was really surprised to see his cold but sometimes sweet best friend's head laid down on his. He blushed immediately. He tried to flinch but his body can't. His brain keeps telling him to move but his body is completely frozen. His body don't want to move away from her; it feels like its the right place to be.

'Let us see how long you can last Conan-kun.' she thought. She wanted to speak but she got the same problem as Conan. Her brain says "move away and laugh out loud in front of his ridiculous looking face" but she just can't; it feels like home. Little did they know, there are people watching them. These people were namely Conan's parents Yuusaku and Yukiko who's camera is already onto them since the beginning, Ai's adaptive father Professor Agasa who's chuckling his belly off, Heiji who is absolutely bored but smiling, Kazuha on the other hand is squealing together with Ran because they thought it was too romantic to not to make a sound.

(A/N: Ran doesn't know that Yukiko and Yuusaku is actually Conan's parents. She only knew that they are visiting their their relative as well as Kazuha.)

"How long do you think they'll stay like that?" Heiji asked annoyingly.

"Shhh. Shush up Heiji. They're having a cute time. And its too cute to disturbed them. Do you really know something about love?" replied by the annoying Kazuha. "Aho, if I don't know something about love how come I'm dating you?" he replied back blushing while the rest of them chuckled. Kazuha immediately stand up straight and shouts Heiji's ears out "A-aHO!" that's all she can say. "I think they're not the only ones who are having a cute time." giggled Ran.

As they turned their attention to the Osakan couple, the kids in the hammock already noticed them and broke apart but Conan's arm didn't move at all. They looked each at each other, blushing and look away as fast as they could. "Wow that was a nice nap." he broke the silence around them while laughing nervously.

"No it's not." she replied coldly but deep inside her it was really the greatest feeling she ever had.

"Okay, that made me feel a bit sad but, there is a way to cheer me up." he said happily and he finally removed his arm around Ai.

"Surprise me." she said sarcastically.

"Can I sing you a song this Valentine's Day as your gift?" he pleaded with his puppy dog eyes. "I wouldn't take no for an answer and if you will still say no, I won't stop until you say yes." he continued.

'He really won't quit it.' she thought annoyingly. She gave a big sigh and said "All right, as long as you practice. I'll be expecting a good performance from you this Valentine's Day." she said honestly and smiling.

"Yes!" Conan shouted that make the eavesdroppers turned their attention back to them and the next thing they saw came into their shock. They can't believe what Conan just did. He kissed Ai's nose to say thank you. He then stand up and ran towards to those people who took their picture more than twice. As he reached his dad he asked excitedly.

"Tou-san do you know someone who can teach me how to sing within less than a month?" he said grinning to his dad.

"Haha, sure I'll find you one son. Your mom can help to you know. Right Yuki?" he turned to his wife and squealed excitedly "Sure! I'm happy to teach my Co-chan."

"Great I can meet him/her as soon as.. Let's say tomorrow?"

"Haha, sure, son. No problem."

"Thanks tou-san. This is going to be fun." He is so excited about what will happen the next day. "Oh yeah HEIJI-NEECHAN, close your mouth it may attract flies." he teased with a huge mocking grin that annoyed Heiji so much making him to do his stare of shut-the-hell-up-brat-or-those-glasses-will-be-around-your-neck.

"Tou-san can I ask something else?"

"Sure, what is it?"

"Can I have a guitar lesson as well? I might have a good use for it someday. But keep it a secret from mom." he whispered to his dad slightly fidgeting.

Yuusaku obviously wouldn't say no for his son. He agreed with a smile of amusement. "I think my son is putting a move eh? The unusual one." he said grinning to his blushing son.

"IT'S NOT LIKE THAT. It-it's just you know." he shouted to his father and just give him a soft smile.

~The Next Day~

"Conan-kun! Your mom is on the phone." shouted Ran.

"Moshi, moshi Kaa-san?" he answered excitedly because he knows that he's vocal teacher will be meeting with him today. "All right Kaa-san I'll be there. Ja ne." he hung up. He picked up his skateboard and bid his goodbye to Ran.

"Oh, Co-chan meet Kyo-chan he is going to teach you some singing." his mom said excitedly as ever.

~After 6 hours~

"Phew, that was hard stuff." Conan said with relief because he can finally rest his voice.

"Wow, Yukiko-chan, I thought you said that he is not the singer type but I have to say he is really something." praised by his vocal teacher with a smile. "He will be in tune for valentine's day in short time." he chuckled teasingly.

"That's great news. Thanks sensei. I'll see you tomorrow then." he said gratefully then took off to where his dad is.

"So, Yuusaku-kun will be teaching him how to play?"

"Yes, This will be fun. Yuusaku is not an expert but he can teach him." Yukiko said with a loving smile.

(A/N: Slightly OC sorry 'bout that)

-in his dad's office-

"Tou-san."

"Ah,there you are. Come to meet your teacher." his dad smiled but Conan is confused.

"Where is he then Tou-san?"

"Well, he is in front of you. Surprise!" his father said totally amused to his son's expression. "Let's get started, but before that." he handed a brand new guitar to Conan and immediately gave a big smile.

"All right we're all set!"

-After 1 week-

~2 weeks before Valentine's Day~

"I guess you're all set Conan-kun." said Kyosuke. "You're in a perfect shape in just one week. Well done."

"Hehe, thanks I'm just really serious about this." he said with a big smile.

"What are you singing anyway?"

"Well.." he then showed the lyrics of the song with chords in it. Kyosuke is smiling. "Wow, how romantic." Conan smiled blushed.

Yuusaku entered the door holding his guitar. "Why did you bring the guitar Tou-san? Kaa-san will find out!" he said in panic but his dad explained that his mother already knows.

"So let's practice with the chords, the strumming, and then the voice." Yuusaku said and Conan didn't think twice.

-3 days before the Valentine's Day-

"Awesome, you know everything and you'll be fine this Valentine's." his mom and dad teased with a smile.

"I guess so." Conan replied quite nervous.

"Do you still have some tricks up your sleeve Co-chan?"

"No Kaa-san. I wanted it to be plain and simple." he said now smiling.

-Valentine's day-

*ding-dong, ding-dong*

"Stop playing in with the stupid door bell will you." Ai said with a hint of annoyance. Why wouldn't she be? In this kind of quiet night, she'll probably in her room reading or looking at her crush's picture. And its not just a 'night' it's Valentine's Day and she really forgot about Conan's present to her. As she opens the door, flowers are right on her face with a little card on it says "Happy Valentine's Ai Haibara/Shiho Miyano". She was slightly confused to her admirer but as the flowers slightly move down and stop covering her eyes, it reveals a four-eyed little boy with a huge grin on his face. She was undeniably surprised and her face makes pout a bit.

"You completely forgot about this, do you?" he asked as if he was like a little boy about to cry.

"No it's not that. I'm just surprise because I thought its just simple singing." she said honestly and still surprised.

"Oh, well, I'm not making it as simple as you think." a radiant smile came upon his face. He took her hand and lead her out the door. "Wait. Before we go." He covered her eyes and continue to walk to the garden where the hammock is.

"Here we are." he then removed his hands out of Ai's eyes. She was stunned by the scene. Their simple garden place feels so romantic. Those sweet scented scattered all around the place, it's more like a there's going to be an engagement rather than just a simple valentine's day gift from a friend.

"Wow, you have this arrange by your own?" she said with a really amazed voice.

"Ah, yes hehe. 'cause I thought it'll be more original if I didn't get any help arranging this kind of things from anybody."

"That explains some of the silly inappropriate things here." she said smirking just trying to play with his feelings but really this is just prefect!

"Hey, that's twice tonight. Just sit down on the hammock and at least try to enjoy this." he pleaded her just to avoid more criticism.

"Whatever. Let's just get this over with." then she sat down and look at him with a smirk. She's not the only who's watching them, there are his parents and hakase hiding and with a camera of course. They can't miss this one.

"All right, well this song is the first song I've ever sing in front of someone else other than mom. Well you might find this a little off, but I guess you'll like it." he smiled then picked up his guitar and start strumming. "This is One and Only You." her eyes widened in shock. 'One and Only You? That was a little off.' she thought but she let her best friend do what he really wanted to do.

It took one look
And forever laid out in front of me
One smile and I died
But I do need to be revived by you

There i was
Thought i had everything figured out
Just goes to show just how much i know
'bout the way life plays out...

I take one step away
When i find myself coming back to you
My one and only, one and only you

Now i know
That i know not a thing at all
Except the fact that i am yours
And that you are mine

Ooh
They told me that it wouldn't be easy
And i know
That i am not the one to complain...

I take one step away

When I find myself coming back to you

My one and only, one and only you

I take one step away

When I find myself coming back to you

My one and only, one and only you.

"Happy Valentine's Ai" he said with his warm warm smile and she sits there still... speechless.

"That was... unusual but still.."

"Still what? Come on don't I'm dying to know!"

"still, Romantic." she flash her best smile to him. "Thanks but I feel bad cause I only got you this." She then stood up, walks in front of him, ask him to stand up and gave him a hug, then whispered "Thanks Conan-kun." He hugged her back and said "You're welcome."

-End of Flashback-

"That was just one good valentine's." he chuckled lightly. He then got up, picked his guitar and ran outside his mansion as quickly as possible, to get back to Ai. He wants to surprise her once again but with a twist.

A/N: I supposed to end this story with this long chapter but I came up with a long flashback and split it into two. Hope you liked it.

Sorry if I didn't write the preparation more detailed.

A little trivia, a hammock is like a long swing that you sleep in it, mostly made of rattan or some net.

And the song I used is One and Only You by Parokya ni Edgar. Some of random names as well, sorry about that.

See ya in my last chapter smiles
