2014...

Yesterday was the first time I met that eonni. What's her name again?

Ah... Jung Yerin. I don't know who she is actually but later I found out that she was the new 3rd year student who just move to our school.

They say she was problematic because she transfer schools a lot. But based on what I saw yesterday, I don't think so.

She looks quiet shy to the people she don't know. She said she was an introvert. That explain why she doesn't have friend and I understand her situation.

School ended as usual and I walked towards the meeting place Yerin said to me yesterday. Yes, I'm headed towards the rooftop.

When I arrived, I saw her side face. Looks like she didn't realize that I was here already. She really looks beautiful like what the students rumoured.

But one thing bothered me.

Just why....

Why did she look so...

sad?

"Eoh... You're here~?", suddenly that sorrowful face changed in a flash into a bright and cheerful face, looking at me happily.

"Eoh...", I answered.

"When did you arrive here?", Yerin asked.

"Just now", I said as I join her staring at the sun who slowly sets down at the end of the rooftop.

"You like it aren't you?", Yerin asked making SinB confuse with the question.

"Ne?"

"The view. Isn't it beautiful? I love to enjoy the dawn view while the breeze flying through me. Its somehow... calming~", Yerin continued.

"Hmm... You are right", SinB smiled a little bit.

"Can I call you... Yerin e-eonni...?", SinB asked nervously afraid that she might be a bit rude to the upperclass student beside her.

"Yeah sure. I would love to", Yerin smiled as her reply.

"Yerin eonni, may I ask you why did you change school? The students said... you made problems at your old school. That's why you change school? I'm sorry if I'm being rude", SinB slightly bend her body afraid that she might hurt Yerin feelings. But instead Yerin showed her a smile.

"It's okay I'm used to that kind of accusation~", Yerin said.

"Actually I was bullied. This is the sixth time in my life that I change schools to run away from the bullies"

"M-Mwo??", SinB was shocked when she learn the truth that actually it was the opposite from what the students rumours.

"I don'tknow why they did it, maybe because I didn't talk much. I couldn't make friends because I move a lot and people misunderstood me as an ignorant and arrogant, ignoring the truth that actually I'm an introvert", Yerin continued.

SinB blinked her eyes for a few times looking at Yerin. So people misjudged her just because she was a quiet person?

"It must be... hard for you", SinB said in guilty.

"It's okay~ I'm used to it~ I'm fine with all of those~", Yerin smiled brightly towards SinB, leaving the younger girl in amazement when she saw how beautiful that smile is.

The new, current, time travelled,

2014.

SinB ran as fast as she can to the 6th floor, trying to find the silhouette of the girl she's missing all this years.

"Jung Yerin!!", SinB shouted when she finally arrived at the rooftop. But sadly Yerin wasn't there.

Yewon said just now that today was 22 March. Yerin died on 5 April 2014, on this rooftop.

"Geez... I only have 2 weeks to save her", SinB said in distraught.

SinB remembered clearly the day when Yerin was pronounced dead. SinB world feel like stopping when she heard about it. SinB did have feelings for Yerin from their 2 weeks friendship.

But what make her more in distress is that the fact only SinB know Yerin was in some kind of problems in her life.

*** Flashback ***

SinB was at her home, having dinner with her mom and dad. But because of today's news, SinB didn't have any moof to eat. She just frozen in her seat.

But then moments later, the main door was knocked from the outside. When Mr. Hwang opened the door, the family was in chock that there's 2 police officers right infront of their door.

"We are from Incheon Police Department. May we talk to Miss Hwang Eunbi for a while?", the policeman said.

SinB get the idea that this maybe something related to Yerin's death. So she didn't waste her time to walk towards the front door and facing the policeman.

"Miss Hwang Eunbi?", he asked.

"Yes I am...", SinB answered weakly.

"You did know what happened to Jung Yerin today aren't you?", he asked and SinB simply nodded her head.

"We've found a diary in her bag and the only name she ever mention inside it was you. Hwang Eunbi", the policeman continued.

"E-Excuse me...?", SinB was dumbfounded with the policeman statement. She cannot understand what are they talking about but then the policeman handed SinB something.

"Here. The diary. It's for you", the policeman said while smiling sadly to SinB.

"What do you mean by all of this? I... I don't understand!", SinB was confused yet her heart began tu shattered again remembering the fact that Yerin was dead.

"We have done enough inspecting this diary. Also Yerin's mom want us to give this to you. Because she think you are the rightful owner of this diary", he said.

Slowly SinB reach her hand, trying to take the diary from the policeman's hand. Tears flowing thru her cheek. Why should a one person death... can be this... painful?

..................................

"Hwang... SinB?", suddenly someone's calling SinB's name at the rooftop. SinB recognized the voice and it belongs to no others than Jung Yerin.

"Yerin... eonni...", SinB turn her head around. Finally.... Finally she can see that beautiful face belongs to Jung Yerin again. The face that she miss all this years. The face that haunting all her life in guilty. SinB miss Yerin a lot.

"Someone said to me, she hear someone from the rooftop shouting my name. I was curious... so I came here", Yerin said. But she didn't get any reply from SinB.

"But hey... why are you crying?", Yerin saw it. Tears was flowing nonstop from SinB's eyes. She was confuse with SinB, but at the same time she was glad that she could meet SinB today. At least she has someone to talk to.

"Yerin... eonni....", SinB said in her low tone, still crying while putting her head down.

"Y-Yes?", Yerin answered in confusion.

SinB finally put her head back up again and slowly walking step by step towards Yerin. Yerin who was still confuse with SinB's act try to keep herself calm and stay standing at one place.

"Eonni..."

"Hmm...?"

In a flash SinB hugged Yerin tightly while putting her head on Yerin's shoulder. Her cries became louder somehow making Yerin a bit worried about the younger girl who she just met yesterday.

"Are you okay SinB? Why are you crying?", Yerin asked worriedly while patting SinB's head on her shoulder.

"Why did you ask me that question?", SinB asked. Yerin eyes was widen in confusion. What did SinB mean with her words just now?

"Ne?"

"I'm the one who should ask you that question. When you said you were okay with everything, did you really mean it....?", SinB asked.
