It was saturday night, Nayeon and Jeongyeon are on their way home when a truck suddenly hit their car. The metal pipe that came from the truck should’ve been for Nayeon if it wasn’t for Jeongyeon who shielded her from the pain of being pierced by a metal pipe. 

"Nayeon.. wa-wake up ple-please. Yo-you need to live.." 
"Jeong..." 
Before they hold hands both of them lost their consciousness.

Nayeon woke up in a white room, no ones there except the girl in the couch.
"Uhh where am I?" Nayeon asked the girl and the girl looks at Nayeon.
"You are in the hospital" she said 
"Uhmm what happened?"
"You were in coma for almost two years" she said and Nayeon look at her in confusion. Nayeon have been in coma for almost two years. Nayeon thinks that it is insane. 
"Are you serious?"
"Yes, I've been watching you for almost two years and I'm glad that you are finally awake"
"Wait who are you?"
"So your memories are completely lost? Aish I know it will happen. I'm Jeongyeon"
"I don't even know your name" Nayeon said and Jeongyeon  just laugh at her, Nayeon thinks it's not funny.
"You'll remember me" those words echoed in Nayeon's head without knowing what was it. 

Days passed but Nayeon still can't remember her, they've been spending days together in a small white room. Nayeon felt something weird last night like whenever she saw Jeongyeon her heart beat so fast. Nayeon knows it's weird because she don't remember or know her very well.
"Is there any problem? Want something to eat?" Jeongyeon asked Nayeon
"Ah no I'm okay"
"Then why are you so quiet?"
"I just felt something weird"
"What is it?" 
"I know it's sound funny or fishy or whatever do you want to call it but whenever I see you my heart beat so fast. What's happening to me? I won't die right?" Nayeon said without hesitation and Jeongyeon laugh at her.  Here we go again, seriously? Do I look like I'm joking? She's weird. Nayeon said to herself.
"Lol no you won't die haha I can't say anything but you'll find the answer to your question soon" 
"Why can't you tell me?" Nayeon said but she just ignored Nayeon's question.
"Btw where's my parent? I didn't saw them when I woke up nor the day I woke up, are they okay?"
"You don't have to worry, they're okay actually they're waiting for you"
"Waiting? But---" she cut off what Nayeon's saying and Jeongyeon just put a piece of bread in Nayeon's mouth. They continue what they're doing and they teased each other. 
The night has come and Nayeon already fell asleep while Jeongyeon stuck staring at Nayeon.
"You need to live, no one can take your life" she said while staring at Nayeon

Nayeon still have one week left and she can finally leave that small white room. She will surely miss that white room. Glad Jeongyeon's there, She's so happy beside her and Nayeon hope that her memories will come back again to her. She's badly want to know who's this Jeongyeon in her life.
"For almost two years of staying here I'm glad that you'll finally leaving this hospital haha" Jeongyeon said and she look at her.
"Will you stay beside me? I mean you won't leave me right?" 
"Lol no I'm staying in your life haha you need to remember me"
When she said that Nayeon's head hurt a little and her heart beat so fast to the point that it hurts too.
"Are you okay?" 
"I'm just tired haha don't need to worry"
"Just sleep Nayeon you still need to rest"
"Come here" Nayeon said and Jeongyeon came next to her
"Sing for me" 
"What? I can't sing very well"
"It's okay I just need to hear your voice before I go to sleep" she sigh but she starts singing. Her voice.. Nayeon already heared this but she can't tell where or when. She start to pat Nayeon's head and she's slowly closing her eyes, signs that she will fall asleep.

Two days left and she can finally go home. She's so excited to go home with Jeongyeon because she said that she will stay in her house. 
"What are you planning to do after this?" Jeongyeon asked 
"I don't have any plans for now" 

It's Nayeon's last day in the hospital but she still have this weird feeling. How do I get rid of that feeling? Is this what they called "love"? Nayeon said to herself. She's started to look for Jeongyeon to ask her what was that feeling.
Nayeon can't find Jeongyeon there.
 Sometimes I want to punch her face she's always like this whenever I want to find her. Nayeon said to herself. The door open and Jeongyeon enters. 
"Ya where have you been?" 
"Woah chill Nayeon I just talk to your doctor and he said that you are fully healed no need to worry, you can finally go home" she said while smiling
"Jeongyeon I have a question"
"What is it?" 
"How can you say that you're inlove?" 
"Ohh what a nice question" she said and she sat next to her.
"How can I say this? Uhm I think the feeling of inlove is when you always think of this one person and you can't stay still. You are comfortable with this person to the point that you see this person as your home"
"Oh okay" 
"So are you inlove?" 
"Uhmm I-- I don't know"
"Who's this lucky person?" 
"Hey I said I don't know if I'm inlove but I think I'm inlove argh don't mind me" Nayeon said and Jeongyeon just laughed at her.
"You're too cute haha" she said and then Nayeon's face became red. Nayeon thinks that this is embarassing. 
"Oh your face-" 
"Shut up" 
"Come on Nayeon who's this person?" 
"No"
"Tell me please?" Aish she's cute how can Nayeon say that she's inlove with this person? 
"It's--"
"Hmm?" 
"IT'S YOU JEONGYEON, I'M INLOVE WITH YOU" Nayeon said and she just smiled at her.
"You may not remember me in your mind but I'm glad that your heart remember me" Jeongyeon said and she's slowly disappearing. Nayeon is in state of confusion. She didn't expect it to come. How can a person slowly disappearing? 
"Jeongyeon? What the is this? Why are your body slowly disappearing? Jeongyeon tell me what's happening?!"
"It's time Nayeon you're awake, that one week thing is your time, when you go back tell our friends that I love them and Nayeon I love you" after she said that she disappear and Nayeon finally woke up. 

"Omg Nayeon's finally awake guys go tell the doctors" 
"My daughter"
"Nayeon-ahh I missed you" 
"Huh? Where am I?" 
"You are in the hospital" she saw Jihyo smiling at her with tears
"You were in coma for almost two years sweetie, I'm glad that you're awake now. It's your birthday now" Nayeon's mom said but if you look in her eyes there's sadness.
"Wait, why can't I remember anything? I know you guys are my friends and you are my mom but why can't I remember this one person?"
"Who?" 
"This person I met in my dream" 
"Sweetie it's just a dream okay?" 
The door suddenly open and Nayeon's friend, Chaeyoung came.
"G-guys"
"What is it Chaeng?" 
"Jeongyeon-ah" Jeongyeon? Nayeon finally remember that name. 
"Mom it's her, she's in my dream. I need to go see her please?" 
"Nayeon-ah" Chaeyoung said but she just ignored her. Nayeon want to see her so bad.
Her friends and her mom hesitate to help her get up but in the end they helped her.

As soon as they arrived in her room she saw that there's so many doctors. Nayeon's other friends are in the bench waiting and they are crying. Why? What's happening? Nayeon can't help but to think negative things. 
After 15 minutes of waiting she saw one of the doctors came out of room, this old lady talk to the doctors and she suddenly cried and her friends comfort her.
 Nayeon doesn't know what's happening 
"Jihyo what happened?" She finally asked her but she just hugged her and she suddenly cry.
Nayeon who doesn't know what's happening started to cry without knowing the reason.
The old lady came to her and she hugged Nayeon.
"My daughter really loves you, I can now understand why she saved you from that accident 2 years ago" 
"I'm sorry but I don't remember anything, can please someone tell me what happened 2 years ago?"
"You and Jeongyeon driving to your way home then a truck suddenly hits your car. Jeongyeon saved you from that metal pipe that came from the truck but both of you are in coma for almost 2 years" Jihyo said and Nayeon suddenly stand up even though she can't walk properly. She badly want to see her. 
She opened the door and she saw her. She started to touched her hand and she felt that coldness in her hand.
 "You can't leave me" Nayeon said to Jeongyeon
"Wait Jeongyeon I remember you, please wake up. You said that you won't leave me. So please fulfill that promise you made" Nayeon started to cry. This can't be happening. 
"I'm so sorry Nayeon" Jihyo said 

My world, my life, it's all gone now. So in the past two years you were here beside me, guiding me and protecting me. 
Now that you are gone, what am I supposed to do now when the best part of my life was you? 

In order to live, one person must sacrifice her life. After the accident the two of them became a prisoner in their dreams but Jeongyeon is the only one who's awake in the dream. So jeongyeon waited for two years and sacrificed her life in order for Nayeon to live. Jeongyeon sacrificed her life to protect Nayeon from dark shadows that wanted to take Nayeon's soul. In order to save Nayeon, Jeongyeon stayed beside her in hoping that she would remember her. Remembering her will save the two of them but Nayeon failed to remember Jeongyeon in her dream but her heart remember her. The mind and the heart should be unite. That's why Nayeon was the one who live because she failed to remember her in her mind. Jeongyeon serve as mind and Nayeon serve as  heart.  When Nayeon finally woke up, it is also the time that Jeongyeon died. Nayeon can still see Jeongyeon in her dreams and everytime Nayeon wakes up she started to cry. 

She always think that it is just a dream
