"10, 9, 8, 7"

Yoona looked at her clock. She smiled.

"6, 5, 4"

Yoona closed her eyes and make her hands crossed.

"3, 2,"

She slowly open her eyes and said.

"1"

She smiled. She must be happy for this day.

"Happy Birthday Yoona" 
She whispered to herself.

She opened the windows and the wind rustled her soft strands of hair. 
She moved her arms back and forth because of the cold breeze or air.

"It's cold during midnight, silly me" 
Yoona said then she let the windows half opened. 
She rested her chin in her hands as she sit resting her back in the wall. 
She sighed.

"What am I going to do this year?" She thought.

It's Yoona's birthday. 
She didn't sleep and waited for 12:00 in the midnight for her birthday countdown. 
Every year in the treehouse, at the very same day, she is always there celebrating her own birthday.

"Aha" Yoona thought of an idea. 
She quickly go down and locked the door. 
She get her bicycle and started riding it. 
She go to the nearest convenience store and buy some food
. 
. 
. 
.

"I can't sleep"
SeoHyun said as she scratch her head sitting at the edge of the bed. 
Suddenly she heard a knock coming from the window. She looked at it and saw no one.

Another knock is heard and it made SeoHyun afraid.

"Who is there"
SeoHyun said as she wrapped her arms around her leg.

"Seo---Hyuu--nnn" 
The person sounded like a ghost, haunting SeoHyun's ears. 
SeoHyun closed her eyes and cupped her ears as if she was hearing nothing.

"SeoHyun it's me!" 
Finally Yoona showed up in the window smiling at her. 
SeoHyun pouted in relief that it's not a ghost or a monster walking around just like in some children's books she always read before.

"Yoona!" SeoHyun pouted. 
Yoona knocked the window for the third time but SeoHyun ignored her pretending to be mad. 
She knocked the door again and showed the food she bought a while ago. 
That caught SeoHyun's attention. 
Suddenly her stomach growled.

"I am hungry" SeoHyun thought then smiled looking at Yoona. 
She opened the window and said.

"What are you doing here, you climb up in our gate again?"

It's Yoona's habit since before that If she wants to go to SeoHyun's house late at night, she will just climb up carefully and knock at SeoHyun's window.

"Yeah, I just want to go somewhere, and eat" Yoona said.

"Where are you going?"

"Go here outside and I will show you one place" Yoona whispered and SeoHyun agreed. 
Yoona slowly opened the gate and left her bike inside the frontyard of SeoHyun.

"Where are we going?" SeoHyun said still in her pajamas.

"I'll just get my tandem bike and we will go to my place"

"But your place is just there" SeoHyun said pointing out their house next to them.

"Nope, not there, at my secret place" Yoona winked.

"Secret place? Lee Yoona I thought we must not hide secrets! and then you have a secret place!" SeoHyun pouted.

"That's why I am going to let you see my secret hide out so I will not have hidden secrets to you anymore, Araso?" Yoona said as she walked and opened the door in their house. 
She placed the things she bought in the basket and called SeoHyun to ride their tandem bike.

"You know you are weird today Yoona" SeoHyun said.

"Why?"

"Because before, you don't want anyone to touch and ride this tandem bike for many many years to be exact 12 years"

Yoona smiled and said. "I just feel to ride this bike again"

"Why?"

"I miss someone, it's the thirteenth year, thirteenth year that we did not ride this bike again" Yoona sighed.

SeoHyun wants to tell something but she hesitates to tell it.

"Yoo..Yoo..Yoona"

"Neh"

"Nothing"

"Is there something that bothers you?" Yoona asked.

SeoHyun took a deep breath and said. "How do you miss..Kibum"

"Miss? How do I miss him?" Yoona said.

"Neh"

"I don't know, but my heart is finding him as much as I want to find YoonMi"

"How about if.."

"If what?" Yoona asked.

"If he is back"

"If he is back, I don't know how I would feel" Yoona said.

"Because I feel It is impossible" She added.

"Impossible?" SeoHyun asked.

"How do you say so?"

"I feel that he already forgot me, You'll know why when we get to that place" Yoona said.

"If you only knew" SeoHyun thought as she sighed

Kibum is there sitting in the chair near the pond in their house. 
It's past 12:00 midnight and he is there blowing his pinwheel he kept for years. 
He is just in his T-shirt and shorts and he felt the coldness of the night.

"I should bring my jacket next time"
He thought while blowing his hands to make him feel warm. 
He felt a pair of hands in his shoulders and someone put a jacket in his back. 
He stared at his back and saw Jessica smiling at him. 
He sighed and then smiled at Jessica.

"What are you doing here It's late now" Jessica said.

"Ahmm, just relaxing" Kibum replied plainly.

"Relaxing? this late at night?" Jessica said.

"It's past twelve, It's morning now" Kibum chuckled.

"Okay, Good Morning" Jessica said as she have a peck on Kibum's cheeks. 
Kibum's eyes widened with what Jessica done earlier.

"Oooopppss... I'm sorry" Jessica's face turned shy and walk away.

"I'll sleep now, have a rest Kibum" 
Jessica looked back and go inside the house.

Kibum sighed. 
Eventhough he really tried his best to fall in love with Jessica, He can't. 
Knowing that he's been already arranged with Jessica and he's been her boyfriend for years, he still can't lend his heart completely to Jessica. 
From the very first time he met Jessica, he known her as a nice girl. 
But still his feelings never grow in Jessica. 
As years go by, he only loves one girl and the longer they don't see each other, the deeper he loves her.

He really tried to forget her but he can't. 
Now he know that he could only end up with Jessica sooner or later, he did tried his best. 
But he is back in Korea, and the memories can't stop from coming back. 
He can't stop thinking about her.

"Did she forget me already?" He thought.

"Chi Chi, Chi Chi!" Yuri's voice is heard.

"What happened to Chi Chi?" 
Kibum asked Yuri who is running around the garden near the pond. 
Chi Chi is the hamster of Yuri. Yuri bought it a week ago there in Korea.

"Chi Chi is lost , Chi Chi is here, I know it, it's just hiding from me" Yuri said worriedly.

Kibum laughed and said. 
"Forget about Chi Chi, maybe she's eaten already by Robby"

"Robby? can a Rabbit eat a Hamster" Yuri pouted.

"Uhhhmm, If not Robby, maybe Chan Chan already eat it"

"Can a Dog eat a Hamster?" Yuri said. 
"Why not" Kibum grinned as a tease.

"Aissshhh!! Aiggooo..." Yuri whispered.

Until someone yelled from the house. 
"AAAAAHHHHHHHHHHHHH!!!"

"It's Tiffany" Kibum said then run inside the house. 
Yuri opened the door and saw Tiffany screaming her lungs out.

"Chi Chi!" Yuri cheered as she get her little hamster with her hands.

"Get that rat out of my bed!" Tiffany squealed.

"Unnie, It's not a rat, it's a hamster" Yuri said as she touch Chi Chi.

"Yuck! I tell you you must buy a dog than that small creature!" Tiffany go back to sleep and buried her head with her pillows.

Kibum and Yuri laughed silently as they have a high five.

"Kibumshhii, why are you still awake?"

"Ahhhmm...just you know breathing some fresh air and thinking of something" Kibum said.

"Kibumshii, I want to go somewhere today, where are your favorite places here in Korea?" Yuri said.

"You really want to?" Kibum asked.

"Of course, I want a very peaceful place"

"Have a sleep first, I'll wake you up at 6:00, It's good having a walk by that time" Kibum said.

"Okay bye" Yuri said as she holded her hamster tightly
. 
. 
. 
. 
. 
.

"We are here" Yoona said. 
SeoHyun looked around and said. 
"How do you know this place?"

"Well Kibum let me know about this place" Yoona replied.

"Oh, there are birds" SeoHyun said pointing out

"Love birds, actually" Yoona laughed as she climb up in the treehouse.

"What are you doing?" SeoHyun asked.

"Just come with me" SeoHyun go up in the treehouse and look inside.

"Wow" 
Yoona sit down and have some snacks she bought a while ago.

"Wow, Yoona you didn't tell all of this, I thought all of your paintings were gone, I thought you w-"

"Yeah, I'm sorry for keeping you all about this, It's just like I promised him that This will be our secret place, you know SECRET" Yoona said.

"But we are supposed to be not keeping secrets right, how many secrets do you have that you haven't tell me" SeoHyun pouted.

Yoona sighed. 
There are lots of it. 
Even keeping SeoHyun's identity. 
SeoHyun never know that she is adopted, and just founded in a plane crash. 
Even the deepest secret , she must hide from her. 
But she is so guilty because of that. 
Guilty while hiding that thing and SeoHyun keeps on trusting her.

"Yah I think and I feel like you don't trust me"
SeoHyun pouted as she digs her spoon into a yellowish blob that was supposed to be some kind of dessert pudding.

"You know, you are my bestfriend SeoHyun, why won't I trust you" Yoona said making SeoHyun smile.

Yoona slouched and bowed her head. 
She extended her arms reaching a small box and opened it.

"What was that?" SeoHyun asked.

"It's my necklace, My sister also have this" 
She said while SeoHyun looks at her face turning sad.

(A/N:If you want to see the necklace just go here and imagine that there is the name of Yoona and YoonMi ahahha!! http://www.runningwithheels.com/wp-content/uploads/2008/12/jennifer-zeuner-silver-diamond-moon-necklace-300x300.jpg)

"It's your birthday right, you must be happy, cheer up" 
SeoHyun said lifting Yoona's chin up.

"You know If I will just turn back time, I think YoonMi and I were not apart, If that thing just didn't happen, I think we are here together, maybe you also meet her" Yoona said as she faked her smile.

SeoHyun patted her shoulders and said. "Its okay, just imagine I am YoonMi just this day"

"Okay, so you are YoonMi now" Yoona said hiding her tears.

"Yoona, Happy Birthday to us" SeoHyun hugged Yoona.

"Are you kidding SeoHyun?"

"I'm not SeoHyun, I am YoonMi" She stuck out her tongue to Yoona.

"You know, It will be the 13th year without my sister celebrating our birthday together"

"Don't be sad, It's your day, let's go somewhere later, my treat" SeoHyun said. "Okay"

*BAM!*

"What is it" SeoHyun said as she stand up.

*BAM*

"What was that" 
Yoona reacted then quickly go down to see what's happening.

And then she saw a box in front of the tree near where the bike is placed.

"What is this" Yoona thought as she tried to reach the box but SeoHyun stopped her.

"No, Wait" SeoHyun stopped her.

"What?"

"Maybe it's a bomb?" SeoHyun said.

"Who will bring a bomb here, no one knows this place" 
Yoona said and reached for the box. 
She holded the box and tried to shake it. 
She opened it and saw a letter.

"Letter?" SeoHyun whispered but too loud to hear.

Yoona opened it and read:

You hear a sound of a crash, right? 
And your friend thought this box has a bomb 
This day I want you to be happy I am longing to see you sometime

Just follow the steps....

"Follow the steps?" 
SeoHyun said.

Suddenly Yoona walked around following something.

"Yoona"

Yoona indeed followed the footsteps with SeoHyun and they reached a tree with a pinwheel moving with each wind that passed by and another small box.

"Another bomb?" SeoHyun laughed who's getting the "scheme"

SeoHyun think of a person who'll do this kind of surprise. 
"I know he did this" She thought.

"Another box SeoHyun"

"From a stalker?" SeoHyun said.

"I don't know, wait let's see" 
Yoona opened a box and saw a bracelet in at and a small note.

"Happy Birthday, Wear it always or else I'll be mad, Just look around and you will know who I am" Yoona read the note.

"Wow, oh it looks so pretty, a pinwheel design? wow it's silver it looks cute, you love pinwheels right" SeoHyun said. 
(If you want to see the pendant of the bracelet, go here http://www.poppytalkhandmade.com/files/images/IMG_1362.JPG)

While SeoHyun keeps on talking and talking, 
Yoona did look around. 
Suddenly she saw a person hiding in a bench near them.

Yoona shouted "Who are you"

Then the person run away.

"Wait!" Yoona said then run.

"Yoona!"

"Hi!" Donghae appeared infront of her.

"Donghae?" Yoona said. 
"Yeah, why are you here this late hour" Donghae said as he yawned. 
"I feel sleepy" he continued.

"Well, why are you here Lee DongHae!" Yoona said.

"Uhhmm, Hi SeoHyun!" Donghae greeted SeoHyun trying to change the topic.

"I am not done with you yet Donghae"

"Hi Oppa!" SeoHyun greeted Donghae helping him to change the mood and discussion.

"Wait, Oppa, why are you here, how do you know this place huh?"

"Well, I already know this place even before, I know that during your birthday, you always come here waiting for the time to be 12:00, right" Donghae said then smiled.

"Yah, you didn't tell me about that!"

"It's a secret right, why would I tell you"

Yoona get the bracelet in the box and showed it to Donghae.

"Thanks" Yoona smiled.

"Thanks for what?"

"Thanks for this" Yoona said and give the bracelet to SeoHyun.

"You must be kidding, I am not the one who give that and besides I am going to surprise you because of this" Donghae get his bag and showed Yoona his gift.

"What is this" 
Yoona excitedly opened the gift and saw her favorite book she longed to read but she has no time.

"Oppa you bought this book just for me!" Yoona cheered.

"Ofcourse, i really saved money for that you know, I know that book is your favorite and you have no time to borrow it from the library that's why I've decided to give you that" Donghae explained. 
Yoona looked at the book with happiness and hugged Donghae tightly. 
"I love you Oppa!!" Yoona said happily. 
Donghae smiled because of her sister's cuteness.

SeoHyun coughed and said. "It's cold outside you know"

"Yoona, won't you invite us in your treehouse?" 
Donghae said breaking the bug. 
Yoona slapped Donghae's hands lightly and said 
"You're so bad"

"I didn't do anything"

Yoona stuck out her tongue and run going to the treehouse. 
Donghae followed and SeoHyun too. 
SeoHyun followed while looking at the bracelet seriously.

"SeoHyun come up here!" Yoona called SeoHyun.

SeoHyun go up and saw Donghae sitting in the floor eating her favorite pudding.

"Yah Oppa! Don't touch my food!"

SeoHyun yelled.

"Don't mind him, just eat his favorite noodles" Yoona said to SeoHyun.

"Yah, that's mine!" Donghae shouted.

"Nope, It's mine now" SeoHyun stuck out her tongue at Donghae and put some hot water in it. Donghae pouted.

"SeoHyun, where are the boxes?"

"Here" Yoona opened it and put the bracelet in her arms.

"Who gave you that? A secret admirer?" Donghae asked.

"I don't know, It says Happy Birthday and I must wear this or else he or she will be mad" Yoona said.

Donghae smiled and give a glance at SeoHyun. 
He winked at SeoHyun slightly.
SeoHyun looked at him and smiled back

Everything is black and dark...

"Yoon--"

"Yoon--"

Whispers and mutters..

"I have a plan"

"What is it?"

"Shhhhhh" 
A girls voice is heard.

Yuri wants and tries to open her eyes but she can't

"We must leave this place before they will get you"

"Huh?"

"We must be together no matter what"

"Look at our necklace"

A picture of two girls holding their hands always flash in her eyes. 
It was so fast.
Every second the picture blinks and flash. 
She couldn't understand.

"This will be our promise, this necklace is our only last remembrance from our parents, and we will promise to this necklace that we will be together forever" Another voice haunts her. 
"Yoon-"

"Wait!"

"AAAHHHHHHHHHH" 
A scream of a girl is heard.

"Yoon-" 
Another picture of a necklace flashed in her eyes and blinks every second.
She tried to reach it but it disappears. 
A light striked her and she is in a place. 
A place, It was a very peaceful place. 
There are 2 girls running back and forth in the garden. 
She tried to talk to the girls.

"Hello, why I am here?" Yuri asked but they didn't answer.

"Yoona, YoonMi, breakfast is ready!"

Yuri heard it but not as clear as it should be. 
And then she saw a mother and a father but with blurred faces.

"Hello"

She walked again but she found herself again in a different place.

"Eomma, Appa!" 
A man and a woman is in a stretcher covered with blood. 
Then her sight become black again.

"Yoo-" 
Another voice 
"Yoon"

She opened her eyes.

"Yuri ahh" 
Tiffany said waking her up. Yuri took a deep breath and smiled so her sister will not worry.
