After work, SinB decided to walk home through the busy streets. Sometimes she can see people helping their friend who is drunk to walk. Sometimes she can see students laughing with their friends. Sometimes she also can see girls hanging out together for some fun.

"Gosh... its really remind me of her...", SinB smirk sadly looking her steps on the ground.

All of sudden rain starts to pour heavily on the city. SinB could only cover herself with her vest as she running through the rain. Everyone was seeking for a dry place, but then SinB spotted an old man who walk so slow thru the rain.

Without thinking much longer, SinB shared her vest with the old man, trying to protect both of them from every cold rain drops. The man flashed his smile to SinB gratefully.

"Thank you miss", he said.

"Not a problem~", SinB smiled back.

They managed to cover themselves from the rain. Standing inside a bus stop, the man again thanking SinB for her kindness.

"You really a kind woman", he said.

"Aniyo~ It's okay ahjusshi", SinB replied.

But somehow the old man keep looking at SinB from her head to her toe. SinB was a bit flustered at first, not until she was startled when the man stated...

"You have some regrets from your past, aren't you?", he ask.

"N-Ne?", SinB eyes was widen for a moment. Then the man examined SinB face again.

"I see that you want to save someone from your past if you could", he continued.

"H-How... How did you know?", SinB ask.

"Here... I will give you this as a reply for your kindness", he suddenly handed out a tiny glass bottle with some kind of crystal blue liquid inside it. SinB was flustered to take it, but slowly she reach the bottle and hold it in her hand.

"May I ask you what is this?", SinB ask.

"This will help you", the old man replied.

SinB take a look at the bottle. Is this some kind of poison? Should she take it? Or maybe not? It's not good to take something from a stranger tho.

"But for--"

SinB looked at her left and she was shocked when the man already gone.

"--what... should I do with this..."

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

Later that night, SinB was ready for bed. But she keep looking at that tiny bottle. What should she do with that bottle?

"Is this supposed to be drink? Or what?"

SinB opened the cap of the bottle, trying to smell the fragrance of the mysterious blue liquid. But then nothing strange coming from it.

"It smells normal tho. Should I... drink it?"

Bring careful, SinB took a sip of that blue liquid as minimum as she could. When she gulp the liquid down thru her throat, she finally coughing in disgust.

"What the heck is this??! It taste like green tea mixed with black coffee! Ewerghh..."

She cleaned her tastebud with some water and then try to drove herself to dreamland. She thought maybe she shouldn't trust that old man words just now. How the heck this mysterious water can help her regrets from the past disappear?

"Nahh~ Let's just sleep...."

"YAAAAAH HWANG EUNBIIII!!!"

"E-Eoh!!? What? What just--"

"Gosh! Are you daydreaming? It still early in the morning tho. I called you thousands time just now and you didn't hear it?"

"A-Ah... mianhae Yewon-ah~"

"Gosh....", Yewon sulking infront of SinB but SinB found it cute.

"You called me last night. You said you want to tell me that you met that new 3rd year student at the rooftop? Don't you remember?", Yewon asked.

"Hmm? Did I?? I called you last night?", SinB was confused. She really didn't call Yewon at all last night. All she remembered is that she drink that strange water and go straight to bed.

"Now tell me... how your first meeting with Jung Yerin yesterday~?", Yewon asked excitedly, anticipating the answers from SinB.

"N-Ne? Are you crazy Kim Yewon? Yerin eonni died 17 years ago? Don't you remember?", SinB was startled. What's wrong with Yewon? She should know already that Yerin was long time gone.

"Oh. She's dead 17 years ago?", Yewon make an ice cold face expression to SinB. SinB couldn't even understand whats wrong with Yewon right now.

"So you want to say that Jung Yerin died when she was 1 years old and at that time we didn't even born yet. Like that?", Yewon answered with her snickers.

"M-Mwo?? Yaahh Kim Yewon are you...."

Wait.

Something is wrong.

Something is definitely wrong.

It was wrong enough for Yewon to not know that Yerin was dead 17 years ago.

But it became unbearably wrong when SinB realized the world is totally wrong.

"Why the heck did I wear my school uniforms....", SinB mouth was agape.

"Isn't it obvious? Today was Tuesday. We have school. That's why", Yewon asked while looking at SinB in confusion.

"W-Wait... why are we at school, Yewon-ah..."

"Ha... Ha... Ha... It's not funny Hwang SinB", coldly asnwered by Yewon.

"What the.... HELL IS GOING ON??!!!!"

SinB try to brain the situation thats happening around her right now. She was at school, wearing her uniforms, obviously Yewon looks younger from what she saw a week ago, also there's lots of students inside the classroom.

"Seolma.... Yewon-ah... don't tell me... this year was... 2014....?", SinB lifted her head up in shock, looking at Yewon with her widen eyes, only get a heavy sigh from Yewon as a reply.

"Gosh..... Hwang SinB what's wrong with you today?? Should I even tell you the date? It's 22 March 2014 you idiot!", again a sigh from Yewon.

SinB was puzzled. What just happen? Did that old man words from last night was true? If it's true, does that mean SinB was back to the past right now? Does that mean....

"Yerin eonni... still alive..."

"I'm pretty sure she is", Yewon replied short.

"YERIN EONNI IS STILL ALIVE!!", SinB stand up from her seat making the class attention was brought to her. SinB then smiled shyly and continue to sit back on her seat.

"Why are you acting so strange SinB-yah? Did you have a fever?", Yewon aksed worriedly while putting her palm on SinB's forehead.

"Ani! But one thing is for sure!", SinB said happily.

"What?", Yewon asked.

"Finally... god gave me a chance to make my regrets disappear!", SinB continued.

"What's wrong with this girl tho...", Yewon mumbled by herself.

SinB then stand up from her seat again and walk away towards somewhere on the 6th floor of the building. SinB know what she want to see thru years of her life was there waiting to be found.

"Yerin eonni..."
