Sojung's cellphone is ringing for numerous times. Calls from the girls. But Sojung doesn't want to pick it up and talk to them. So then after upteenth time, Sojung decide to turn off her cellphone.

Sorry, girls...

I don't think I'm sane enough to talk to you right now. I don't want to say rude words to you.

Just give me time to calm down first.

I promise to talk to you when I'm ready.

Sojung thought.

*****

Seoul. GFriend dorm. Maknaes room.

"I can't stand still. I have to do something. Anything! I have to find that Jerk and beat him up!!" SinB exploding.

"Huft~... I know how you feel, SinB-ah. I want to do that too. But I think it's not right choice." Umji trying to calm her roommate down.

"Argh! You are too much thinking, Yewon-ah! You being too make sense. I can't do that. I'm too angry. I have to vent this anger. It's killing me.... that Jerk really pain in the ! How could he found Unnie and did those rudeness to her after all these years... ARGH!!" SinB messing her own hair and kicking aimlessly into the air, just trying to expressing her upset.

"Uhmm.. but isn't weird that he could found her, not too long after we found her. It's too weird as coincident. Was any of us maybe leaked it?" Umji sharing her opinion.

"What?! One of us leaked it? Who? Me? You? One of our unnies? Manager-Oppa? CEO-Nim? I don't think so... they... we won't do something like that. It's too silly. Afterall we all promised to not tell anybody else." SinB argue.

"Yeah, I agree it's too silly. But what about if it happened by accident?..."

"Accidently?.... uhmm...." SinB thinking about the possibillity, "Did one of us post something on SNS?"

"SNS? Uhmm... yeah it could be one of posibillities..." Umji considering, "But trust me, I didn't do it. I even almost forget about my cellphone once I saw Sojung Unnie, Joonwoo, and how pretty their house. I just used my cellphone after we at here, at Seoul, I even had to charged the empty battery on our practise room, my cellphone was completely dead after days I'm not used it at all. And I definitely didn't post anything on my SNS about Sojung Unnie."

"Yeah. Me too. I had fun played with Joonwoo or helped Unnie at her grocery store, or even just walked on the beach of their backyard. I also almost not used my cellphone. But how about our unnies?..."

"Maybe we can ask them..."

SinB sigh, "I really wish that it's not because one of us..."

"Yeah... me too." Umji said, "I can't imagine how I should respond if turns out it because of one of us. It's too surreal..."

So then, Maknaes decide to ask their Unnie. The 5 of them gather on the living room.

"Unnies... did any of you... uhmm... by any hance... huft~... told someone else than us about Sojung Unnie at Jeju?" SinB stutterly ask.

"Do you suspecting one of us as the culprit?" Yuju ask back in disbelief.

"Are you out of your mind?!" Eunha also sound offended.

"Uhmm... we're so sorry. But Unnies, try think another alternatives... are there? Because SinB and I had thought about this... and we didn't found another possibilities. Beside her family, it's just us, Manager-Oppa and CEO-Nim who know about Sojung Unnie at Jeju. After all these years, we just found her recently, few days ago. How come that jerk also found her today? It must be there connection... don't you think?" Umji trying to explain.

Yerin sigh, "I understand your logic. Indeed it's feel too 'in time' with our moment we found her recently."

Yerin take a deep breath, then with more firm tone she says, "Girls... Maknaes are right. We have to find the cause, we have to find the culprit. For Sojung Unnie and Joonwoo's sake. Unnie almost refuse us to back into her life. She said she's too scared to take the risk that somebody else found her there and blow up about Joonwoo to public. She don't want to lose Joonwoo. She sacrifice her life and her career and even us/our group for her son. She begged so hard to us and we promised to keep it as a secret, remember?"

The girls sadly nod.

"But what we should do to help?" Eunha questioning.

"To be honest.. I don't know... are there any of you have idea? Let's discus it together. Let's figure this out together." Yerin said.

*****

Days after, at Jeju...

There's nothing happen in particular. As if nothing bad things happened. It's been normal days, it gradually makes Sojung calm back down. That's why on that peaceful afternoon Sojung feel at ease to pick up the phone call with notification from 'Yerin' name on her phone screen.

*on phone conversation*

Sojung : "Hello"

Yerin : "Sojung Unnie..."

Sojung : "Eung. What's up Yerin-ah?"

Yerin : "Are you okay? Is everything's fine? Is that jerk come again and make trouble?"

Sojung : "Fortunately no. I hope he never comeback again, so currently is fine. I'm okay. How about you and the girls?"

Yerin : "Glad to hear that. Yeah, we're okay too. We have hectic schedules as usual. By the way... I'm at the emergency exit stairs of TV Station right now... your favourite hideout, right? (Chuckle) It remind me of you, Unnie, that's why I decided to call you."

Sojung : "Well... it's been long time since I hide on place like that..."

Yerin : "You hiding at Jeju now, remember?(chuckle)"

Sojung : "(sigh) Unfortunately my current hideout already caught up... so where I should hide onward?"

Yerin : "(sigh) Unnie... Promise me that you will tell me whenever you'll go... I don't want to lose you again."

Sojung : "With the risk of being found again? You kidding, right?..."

Yerin : "It's not one of us. Trust me."

Sojung : "You can prove it? Then who the culprit is? Who the one should responsible?"

Yerin : "(sigh) To be honest, I don't know... but we here are also trying to find it."

Sojung : "(sigh) Yerin-ah... can't you just forget about me? Just live your life without me. You all had done it so well before we met, also you doing great these past 6 years without me. So just keep going..."

Yerin : "Eventhough what you said is correct, but Unnie, you had filled our life in between the time we live without you. If before we met, we were indeed done fine, grown up fine, but after you came into our life, you completed our life become better. Then eventhough we look just fine after you left us, but actually deep in our heart, your spot in our heart is irreplaceable, it's empty all these time and just you who able to fill it again. Our life is incomplete without you. I'm sure you feel the same like we do..."

Sojung : "..."

Yerin : "Am I right, Unnie?"

Sojung : "(sigh) I hate to admit it. But... yes, you're right."

Yerin : "(tears up) So then promise me! Don't make we have to looking for you on the next years. It's hard for all of us, you know? Please... don't leave us again without track."

Sojung : "(sigh) I don't know, Yerin-ah... I just can't ignore the fact that everytime I let you all back into my life, then it make my life and Joonwoo become harder... i'm struggled before you came, and now I'm become even more struggling."

Yerin : "(sob) Oh... sounds aweful~... it makes me feel guilty by heard that...."

Sojung : "I'm sorry. I sound too rude?"

Yerin : "No. Don't be sorry, Unnie. It's not because it sound rude... It's just... the bitter reality that we have to face."

Sojung : "..."

Yerin : "(inhale a lot) It's hard for all of us. It's even harder for you... I know. But I beg you, Unnie... please... don't leave us again. Don't shoo us away again. Let we help you. We can make these works by working it together."

Sojung : "..."

Yerin : "We are no longer your naughty clumsy childish babies who used to need you to feed us to made sure we ate properly, or need you to told us, scold us over and over again to made sure we walk right on path. We all grown up now. We also can do something for your sake."
